Abstract
Systems and methods are described synchronizing communications frames and their respective time slots for satellite communications architectures having multiple satellites in the same orbital slot in such a way that addresses inter-satellite inter-beam interference. In some embodiments, the first and second satellites communicate with a respective number of ground terminals (e.g., gateway and user terminals) according to first and second satellite time slots, respectively. The satellites maintain relative positions in their orbital slot to manifest a maximum path delay difference between first and second path delays, the first path delay being between the first ground terminals and the first satellite, and the second path delay being between the first ground terminals and the second satellite. A synchronization system can offset the first satellite time slots from the second satellite time slots as a function of the maximum path delay difference.
