Problems solved by technology

Existing tracking methods can well meet the tracking requirements of spacecraft targets, but they are risky or even unavailable for various non-spacecraft targets. For example, this is especially true for ship-borne targets. The trajectory and attitude of ship-borne targets have Randomness, often deviates from the predetermined trajectory, affecting the stable transmission of signals

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 shown relay satellite tracking device, the device includes:

[0057] The SSA link module 31 is used to establish the 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; Antenna correction parameters are generated at the predetermined position of the antenna; 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 also used to: send the forward SSA link establishment signal to the target terminal; receive the network access application fed back by the target terminal according to the forward link establishment signal; identify the target terminal according to the network access application, and establi...

Abstract

The invention provides a relay satellite tracking method and device, and relates to the technical field of space-based measurement and control, and the method comprises the steps: building an SSA linkwith a target terminal; receiving a current position returned by the target terminal through the SSA link; generating an antenna correction parameter according to the current position and a predetermined position of the target terminal; and sending the antenna correction parameters to a relay satellite, so that the relay satellite performs antenna direction correction. According to the invention,the actual position of the target terminal can be acquired by establishing the SSA link, and the antenna finally points to the actual position of the target terminal according to the deviation between the actual position and the predetermined position, so that the problem of inaccurate antenna pointing is solved, and stable and high-speed transmission of signals is realized.

Description

technical field [0001] The invention relates to the technical field of space-based measurement and control, in particular to a relay satellite tracking method and device. Background technique [0002] Relay satellite is a kind of communication satellite, which is mainly used for data transmission, and its characteristic is a large amount of data transmission. Relay satellites can provide data relay and measurement and control services for satellites, spaceships and other spacecraft, greatly improving the efficiency and emergency response capabilities of various satellites. Existing tracking methods can well meet the tracking requirements of spacecraft targets, but they are risky or even unavailable for various non-spacecraft targets. For example, this is especially true for ship-borne targets. The trajectory and attitude of ship-borne targets have Randomness often deviates from the predetermined trajectory and affects the stable transmission of signals. Contents of the in...
