On Effects of Antenna Pointing Accuracy for On-the-Move Satellite Networks

In this paper, we study the adjacent geostationary satellite interference to/from on-the-move platforms with motion-induced antenna pointing errors. First, using satellite geometry, we derive tight upper and lower bounds for the average uplink and downlink interferences. Then, we derive the exact distribution of the adjacent satellite interference, and using a Gaussian approximation, we compute bounds for the outage probability for both links. Finally, the outage performance is investigated by simulations and by evaluation of the derived expressions. The performance results show the accuracy of the analytical expressions and quantify the link degradation due to random antenna pointing errors in on-the-move satellite communication systems.
