Embodiment 1
[0030] Embodiment 1 of the present invention provides a relay satellite tracking method, see figure 1 The shown relay satellite tracking method flow chart, the method includes the following steps:
[0031] Step S102, establishing an SSA link with the target terminal.
[0032] Before the start of the mission, first set the state of the relay satellite, including forward return SSA transponder center frequency, satellite-ground frequency, gain gear, forward return Ka-band Single Address link (Ka-band Single Address, KSA) forwarding The setting of the working frequency of the transmitter, the satellite-to-ground frequency, and the gain file. While setting the status of the relay satellite, configure the data transmission task of the ground station. The forward and backward SSA link only uses the channel of the system and does not use the terminal equipment of the ground station, so only the intermediate frequency switch matrix and radio frequency link need to be configured; The...
Embodiment 2
[0056] Embodiment 1 of the present invention provides a relay satellite tracking device, see image 3 A structural block diagram of the relay satellite tracking device shown, the device includes:
[0057] The SSA link module 31 is used to establish an SSA link with the target terminal; the location module 32 is used to receive the current position returned by the target terminal through the SSA link; the parameter module 33 is used to receive the current position and the target terminal according to the current position and the target terminal. The predetermined position of , generates antenna correction parameters; the correction module 34 is configured to send the antenna correction parameters to the relay satellite, so that the relay satellite performs antenna pointing correction.
[0058] The SSA link module is further configured to: send a forward SSA link establishment signal to the target terminal; receive a network access application fed back by the target terminal acc...
