Patent ID: 10819419

Abstract:
A system and method for timing synchronization of satellite switching instants with gateway switching instants is described. The method includes: generating satellite switching instants according to a Beam Hopping Time Plan (BHTP); generating gateway switching instants according to the BHTP; transmitting a channel addressed to a plurality of beams hopped according to the BHTP based on the gateway switching instants, wherein each of the plurality of beams includes a signal including timing markers and a guard period at an end of the signal for the respective beam; receiving a synchronization information, without a loopback beam, for one of the plurality of beams; determining an adjustment period and an adjusted symbol rate for the generating of the gateway switching instants, based on the synchronization information, for a transmission of the channel such that at least a portion of the guard period in a respective signal for a respective beam aligns with one of the satellite switching instants; and adjusting a timing and a symbol rate of the transmission according to the adjustment period and the adjusted symbol rate, respectively.
