  • Characterization and Analysis of Propagation Time Delay Range within NigComSat-1R Footprints
    A.T. Ajiboye, A.O. Yusuf, A.R. Ajayi
    Nigerian Journal of Technological Development, 2019
    NigComSat-1R could be part of Networked Control Systems (NCSs) to link plants, controllers, sensors and actuators which may be distributed within the satellite footprints. Associated with NCSs is location-dependent time delay which can drastically reduce system Quality of Performance (QoP), or in the worst case lead to system instability. To ameliorate these effects, the network delay should be taken into consideration at design stage. In order to achieve this, the ranges of propagation time delay incurred within a particular footprint or between two footprints of NigComSat-1R are modelled, simulated, characterized and analyzed. It was observed that the minimum and maximum possible time delays between the boundary of NigComSat-1R footprints and the satellite are 0.1193 sec and 0.141 sec respectively. Also, the minimum possible propagation time delay between any two footprints is that between C-band ECOWAS 1 beam and itself with value of 0.2386 sec while the maximum possible propagation time delay between any two footprints is that between L-band Navigation payload L1 beam and itself or L-band Navigation payload L5 beam and itself with value of 0.2832 sec. Keywords: Footprint, networked control system, Nigcomsat-1R, propagation time delay, quality of performance
