    Sukabya Dan, Atanu Santra, Somnath Mahato, Chaitali Koley, P Banerjee, and Anindya Bose

    2022 3rd URSI Atlantic and Asia Pacific Radio Science Meeting, AT-AP-RASC 2022, Published: 2022 IEEE
    Global Navigation Satellite System (GNSS) signals are frequently used for ionospheric studies, costly geodetic or special purpose receivers are utilized for the purpose. Compact, low-cost, dual-frequency GNSS modules are commercially available now, those are typically used for cost-effective geolocation applications. This manuscript presents the results of the study to explore the applicability of such compact modules for ionospheric studies. S4 indices are calculated and compared for GPS, GLONASS and Galileo signals for multiple frequency bands using data from two Ublox F9P compact modules concurrently operating with a geodetic GNSS receiver, and the values from both types of devices are found to be in good agreement. The results show the potential of the compact modules for the purpose in a cost and size efficient manner.

    Somnath Mahato, Mrinal Goswami, Surajit Kundu, and Anindya Bose

    2022 3rd URSI Atlantic and Asia Pacific Radio Science Meeting, AT-AP-RASC 2022, Published: 2022 IEEE
    Global Navigation Satellite System (GNSS) Real Time Kinematic (RTK) is a popular technique for obtaining instantaneous high-quality position solutions. This manuscript presents the novel results on the usability of compact, low-cost, dual frequency GNSS modules with commercial GNSS patch antenna for RTK Rover applications instead of conventional geodetic grade, costly receiver-antenna combination. Using concurrent data from two such modules (uBlox ZED F9P and NTLab 104) and a uBlox antenna for short to long baseline lengths, the results establish the suitability of such modules for use as RTK Rovers. Up to a baseline distance of more than 200km, submeter level precision has been obtained in GPS+GLONASS hybrid operation. The results would be useful for the GNSS user community in cost and power efficient application development without dense Base station network.

    Somnath Mahato, Mrinal Goswami, Surajit Kundu, and Anindya Bose

    2nd International Conference on Range Technology, ICORT 2021, Published: 5 August 2021 IEEE
    With the evolution of multi-GNSS in satellite navigation, there is a general tendency to combine satellites of different constellations. GPS+GLONASS hybrid operation has attracted the attention of the users for defense applications from India. An attempt has been made in this paper to compare the precession and accuracy parameters between the GPS and GPS+GLONASS combination for test range applications in the Indian defense programs. It has been observed that GPS+GLONASS hybrid operation provides a slightly better 2-Dimensional (2d) performance while the standalone GPS offers slightly improved 3-Dimensional (3d) performance as found from the precession parameters. This can be an important finding in applications of Multi-GNSS in Indian missiles and other airborne vehicles, and also for calibration of missile and satellite test ranges of India where the height is also an important parameter for consideration.

    Debipriya Dutta, Somnath Mahato, Sukabya Dan, Atanu Santra, P. Banerjee, and Anindya Bose

    2nd International Conference on Range Technology, ICORT 2021, Published: 5 August 2021 IEEE
    NavIC is India's own regional satellite-based navigation system that operates in L5 and in the unique S-band of frequencies. Still now, NavIC single point positioning is done and NavIC PPP or RTK is not availabel. Therefore, to find out a method for obtaining the best possible solution quality using NavIC dual frequency operation, this paper studies the ionospheric delay in L5 and S bands and the associated dual-frequency position solution qualities from two locations in eastern India. It is seen that the ionospheric delay (ionodelay) values are least during early morning hours (3–6 am IST) and the ionodelay values are less in S-Band. The solution qualities are also found to be the best during that same time span as observed through repeated data for several days. Till the availability of NavIC PPP, differential NavIC or NavIC RTK, therefore, for obtaining the best possible precise location solution in NavIC standalone mode, data should be collected during 3–6 am IST.

    Sukabya Dan, Atanu Santra, Somnath Mahato, and Anindya Bose

    Sadhana - Academy Proceedings in Engineering Sciences, ISSN: 02562499, eISSN: 09737677, Published: 1 December 2020 Springer Science and Business Media LLC
    Navigation with Indian Constellation (NavIC) is designed and deployed by Indian Space Research Organization (ISRO) as an indigenous, regional navigational system to provide precise PVT information over the Indian region and surrounding areas. This paper presents a detailed analysis of NavIC visibility under open sky and constrained condition over the service region using an in-house developed simulation tool, the effects of NavIC satellite geometry on single-point solution accuracy and NavIC single and dual frequency solution performances. The results show the potential of NavIC as an alternative navigation system for India and the neighbouring countries in south and south-east Asia, and over an economically important area containing major sea-routes. Even in constrained-visibility conditions, NavIC with its typical constellation design can offer seamless navigation solution over a large region of the globe; the unique S-Band NavIC signal supports enhanced accuracy for stand-alone operation. The results would be beneficial for understanding the potential of NavIC for the user community.

  • Potential of multi-constellation global navigation satellite system in indian missile test range applications
    Mrinal Goswami, Somnath Mahato, Rowdra Ghatak, and Anindya Bose

    Defence Science Journal, ISSN: 0011748X, eISSN: 0976464X, Pages: 682-691, Published: 12 October 2020 Defence Scientific Information and Documentation Centre
    In this paper, the potentials of using Global Navigation Satellite System (GNSS) techniques in the complex calibration procedure of the tracking sensors for missile test range applications have been presented. The frequently used tracking sensors in test range applications are- electro-optical tracking stations (EOTS) and tracking radars. Over the years, the EOTS are used as the reference for bias estimation of the radars. With the introduction of GPS in test range applications, especially the DGPS, the reference for bias estimation got shifted to DGPS from the EOTS. However, the achievable position solution accuracy is limited to the order of a few meters for DGPS, EOTS, and Radars. With the evolution of Multi-constellation GNSS and carrier-phase based measurement techniques in satellite navigation, achievable position solution accuracies may be improved to sub-meter level. New navigation techniques like real time kinematic (RTK) and precise point positioning have the potentials for use in the calibration procedures of the missile test ranges to the accuracies of centimeter-level. Moreover, because of the availability of a large number of navigation signals over the Indian region, multi-constellation GNSS receivers can enhance signal availability, reliability, and accuracies during the calibration of missile test ranges. Currently available compact, low-cost GNSS modules also offer the possibilities of using these for cost-effective, networked RTK for dynamic calibration of test ranges reducing cost and resource requirements.

    G Jyothi, B Dhanraj, J Pavanija, G Kiran Kumar, Anindya Bose, and Pratibha Verma

    Proceedings of CONECCT 2020 - 6th IEEE International Conference on Electronics, Computing and Communication Technologies, Published: July 2020 IEEE
    In this work, a method for velocity estimation of the user is done using a GPS-IRNSS/NavIC/ SBAS (IGS) receiver. With the help of the receiver in a moving vehicle, dynamic data is logged continuously in IRNSS/ NavIC+GPS hybrid operation to get receiver’s coordinates, Geometric dilution of precision (GDOP) and receiver’s velocity. The logged values of receiver’s coordinate contain errors, which is minimized first considering Satellite Selection Algorithm (SSA) based on GDOP values and then by applying PSO based algorithm to reduce Doppler shift effect and receiver’s clock offset. After improvement of dynamic receiver’s coordinates for each observation, velocity of receiver is calculated. Results show that velocity obtained using this estimation technique is more accurate in comparison to the velocity information provided by the IGS receiver. This finds major applications in real time vehicle tracking for various applications. In addition, atmospheric delays are expressed here in terms of Doppler shift.

    Proceedings of CONECCT 2020 - 6th IEEE International Conference on Electronics, Computing and Communication Technologies, Published: July 2020 IEEE
    In this work, mathematical formulations are established for calculation of atmospheric delays against elevation angle of satellites after the statistical study of data of different days scattered over a year recorded by GNSS receivers. Two GNSS receivers used are JAVAD TRIUMPH LS and IGS GPS+NavIC receivers. Position error of GNSS receiver coordinates are minimized using satellite selection algorithm and iterative least square method (ILSM) in which derived mathematical formulations are considered for Ionospheric and tropospheric delays against elevation angle of satellites. The results obtained for horizontal position errors in case of mathematical formulations of atmospheric delay using polynomial curve Fitting method is [-1, 0.5] in x-coordinate and [-0.7, 0.6] in ycoordinate. Algorithm and statistical studies are done based on GPS+IRNSS/NavIC constellation.

    2020 URSI Regional Conference on Radio Science, URSI-RCRS 2020 - Proceedings, Published: February 2020 IEEE
    Besides core services like Positioning, Navigation and Timing (PNT), Global Navigation Satellite System (GNSS) is used for atmospheric and ionosphere probing since the deployment of the systems. Costly and high data rate geodetic receivers are usually used for such research. These receivers may not be affordable for many users and cost reduction of probing systems may be useful for ongoing research. Low cost, compact, multi-frequency and multiple constellation enabled GNSS modules are recently being increasingly available in market those may be used for atmospheric or ionospheric research. In this manuscript, study results on suitability of such compact, cost-efficient GNSS modules for GNSS-based ionospheric research is presented. Low-cost single board computers (Raspberry Pi, RPi) interfaced with the module may be used for data recording. Approximate cost for such complete prototype unit would be around USD 360 (around INR 26,000) Signal strengths of GNSS satellites in terms of C/NO values may be extracted from the recorded NMEA data sentences and related atmospheric parameters can be derived from the C/NO values. This low cost, compact setup may be deployed at a fixed location or multiple such units may be deployed over a distributed geographical region for realtime, networked monitoring purpose. A comparative study on signal strength obtained from standard survey grade GNSS receivers and such low-cost receivers is made. For the module used in this effort, 6dB-Hz difference is witnessed between the values, but both the types show similar signature of signal strength variation. A properly calibrated system may be useful for designing cost- effective, GNSS-based ionospheric research.

    Requirement of accuracy and reliability of position solution obtained from satellite-Based navigation system provided by the Global Navigation Satellite System (GNSS) depends on the application. In some cases, meter level precision is required while cm or mm level accuracy is required for other precision applications. Surveying is one of the important applications of GNSS. Surveying of forest is a challenge for survey engineers in determining accurate position, because satellite signals frequently fade by stems and leaves of the tress. Consequently, the observables become noisy that affects quality of position solution. Real Time Kinematic (RTK) is a popular GNSS positioning method used in case of various precision applications. High cost receivers may provide better RTK solution those are not affordable for many surveyors. Low cost, single frequency, multi-GNSS enabled receiver are available in market those can provide raw data and can be used for RTK. In this paper an effort is presented to assess the precision and reliability of position solution obtained from the low-cost receivers within Indian forest environments. In the first case study over a short baseline, position solution precision provided by a low-cost Rover operating in forest is studied, and meter level of precision is achieved in GPS+GLONASS+Galileo mode. In second case study for long baseline RTK operation, reliable solution is obtained in GPS+Galileo+QZSS mode from a low-cost Rover operating within forest environment. So, reliable or precise position solution can be achieved using low cost receivers and suitable multi-GNSS combination under forest canopy.

    Global Navigation Satellite Systems are being increasingly used for myriads of applications. Along with many global systems, various regional systems are also deployed to exploit commercial potential, for strategic point of views and self-reliance. IRNSS/ NavIC is one of such regional systems developed by ISRO. NavIC enabled, costly, geodetic receivers are available in market and at the same time, few NavIC enabled chipsets also are being offered by manufacturers. These NavIC chips are low cost but the associated receiver board costs are much higher in comparison to the chipsets. Compact, cost-effective NavIC receiver boards are essential for NavIC based application development, popularization and effective utilization of the system. This manuscript presents an effort towards development of a compact, cost-effective NavIC receiver board and the results on the solution accuracy obtained from it. The power-efficient board operates in L5 band and is of 8 cm  10 cm size. The module is working properly both in static and dynamic operation and can provide meter level 2-dimensional precision; the altitude variation is found to be higher in comparison. Final cost of the prototype board is less than US$ 60 which may be reduced during bulk production. The board can be used with Raspberry Pi (RPi) or other controller boards for ASCII NMEA data reception, display and recording. The board has the potential for using it as a stand-alone receiver, for integration with other systems towards application development or as a geolocation sensor in IoT applications enhancing the possibility of deployment of multiple sensors because of cost, power and size efficiency.

    2020 National Conference on Emerging Trends on Sustainable Technology and Engineering Applications, NCETSTEA 2020, Published: February 2020 IEEE
    Modern smartphones are used for various purposes other than core telephony services. They are equipped with GNSS sensors and therefore are used as personal navigation devices. Presence of capable GNSS hardware enables them to be used for collection of GNSS data for geomatic application or basic GNSS research. With evolving Android versions, more capabilities are being included in such devices for collection of basic to raw GNSS data. In this paper, an effort has been made to study the capabilities of commonly available smartphones for use as a GNSS data collection device. Comparative analysis is made on the signal usability, satellite geometry, position solution accuracy and signal strength monitoring. GNSS data obtained from these commonly used Android based smartphones may be useful for positioning service community, training and basic GNSS research.

    2019 2nd International Conference on Intelligent Communication and Computational Techniques, ICCT 2019, Pages: 166-169, Published: September 2019 IEEE
    In this paper, an effort to reduce the position error obtained from GNSS receivers-using Iterative Least Square Method (ILSM) and Particle Swarm Optimization (PSO) based algorithms for IRNSS and GPS constellation is presented. RINEX data from GNSS receiver is used as input for algorithms presented in the work. First satellite selection algorithm to obtain best GDOP is implemented to select best satellite set to prevent unnecessary navigational signals reception from multiple satellite constellations. Then ILSM and PSO algorithms are applied individually to the receiver coordinates obtained. Results are compared those show that PSO algorithm has better efficiency than iterative algorithm to minimize the position error solution in terms of precision. GNSS receiver coordinates within ± 10m error range is obtained,

    Advances in Space Research, ISSN: 02731177, eISSN: 18791948, Pages: 3131-3138, Published: 15 May 2019 Elsevier BV
    Abstract Indian Space Research Organization (ISRO) has developed an indigenous system named Indian Regional Navigation Satellite System (IRNSS) or NavIC (Navigation with Indian Constellation), that consists of 7 satellites and transmits navigation signal in L and S bands. ISRO, for validation of the system, has installed many IGS (IRNSS/GPS/SBAS) receivers scattered over the Indian region. Using preliminary data from two geographically widely separated stations over India, this paper presents the results on studies on parameters of IRNSS signal quality and discusses how these parameters may be used to study the ionospheric behavior over the Indian region. The results show the importance and advantages of using IRNSS data for such studies.

    Advances in Space Research, ISSN: 02731177, eISSN: 18791948, Pages: 2995-3008, Published: 1 May 2019 Elsevier BV
    Abstract Indian region is expected to receive signal from multiple satellite-based navigation systems for multi-GNSS hybrid operation. Even in presence of GPS, GLONASS and GALILEO signals together, it is regularly found that, during some parts of the day no GNSS satellite is available above 60° elevation angle from large parts of India. This may cause problem in seamless navigation solutions in the locations, where visibility of the satellites is also obstructed in the lower elevation angles, which is a common feature in Indian urban conditions; the situation also degrades satellite geometry. IRNSS/NavIC is Indian indigenous regional navigation system operational since 2016. This paper presents theoretical, simulated and initial results of real-time studies on IRNSS/NavIC visibility from India using a IRNSS-GPS-SBAS (IGS) receiver. The studies show that, in such situations of inferior GNSS satellite visibility, IRNSS/NavIC operating together with GPS, can augment this time-dependent degraded visibility conditions. The Indian satellite navigation system ensures presence of at least one satellite above 60° elevation for use with GPS over the Indian region, supports multi-GNSS operation towards seamless solution, and improves satellite geometry.

  • Preliminary results on the performance of cost-effective GNSS receivers for RTK
    Somnath Mahato, Atanu Santra, Sukabya Dan, Partha Rakshit, P Banerjee, and Anindya Bose

    2019 URSI Asia-Pacific Radio Science Conference, AP-RASC 2019, Published: March 2019 IEEE
    Global navigation satellite systems (GNSSs) is currently used in myriads of applications and at the same time internet-based applications are also growing. In case of GNSS, stand-alone, single receiver-based position solution accuracy may not be enough in many applications like automated transporting service, unmanned air vehicle, Geodesy and agriculture etc and GNSS mass market needs low cost high accurate position solution. Carrier phase measurement-based position solution is more precise than code-based measurement, but phase ambiguity is a problem in carrier phase-based measurement. Real time Kinematic (RTK) technique is a method where precise position solution can be obtained using Network Transfer of RTCM message through IP (NTRIP) protocol; here multiple signal messages (MSM) are also sent from the GNSS base station to the rover and Carrier ambiguity can be resolved. This research work focuses on the RTK performance of geodetic, survey-grade receivers and low-cost receivers and analysis on their comparative performances. Geodetic receiver uses its own algorithm to calculate RTK solution and for the low-cost receivers, an open-source GNSS data processing software, RTKLib has been used. A static survey is made and found that low cost receivers can provide sub meter level precision in RTK operation which may help in GNSS mass market application and solution development.

    1st International Conference on Range Technology, ICORT 2019, Published: February 2019 IEEE
    Low-cost (around 100–200 US$), compact, low-power consuming GNSS modules are being increasingly available in the global market recently; precision and capability of such modules may open new prospects of solution developments. One of the methods of enhancing the quality of solution is the use of Real-Time Kinematic (RTK) method using such modules. This paper presents the results of the preliminary studies on the performance of such modules using Multi-GNSS from India. Comparison of performances of geodetic receiver and low-cost receiver as Base and low-cost, single frequency receivers as Rovers operating in short-baseline, static mode has been presented here. The results show decimeter-level solution performance in both the cases; the results may be useful in enhancing the confidence of using such systems for various applications including strategic ones.
