Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The specific embodiment is carried out on the premise of the technical solution of the present invention, but the scope of the present invention is not limited to the specific embodiment.

[0016] Such as figure 1 As shown, for the satellite, an independent communication processing module is added inside the on-board payload and the measurement and control transceiver, and an emergency channel is constructed between the communication processing modules. The emergency channel is independent of other devices and the bus in the star. The communication processing module connected through the emergency channel can enable the satellite and the outside to independently send and receive data through the on-board payload and measurement and control transceiver. If there is no such independent data transmitting and receiving device in the satellite, th...

Abstract

The invention relates to an aerospace vehicle which comprises the components of an on-vehicle load, a measuring and controlling transceiver and a bus. Indirect data transmission is performed among ground, the on-vehicle load and the measuring and controlling transceiver through the bus. The on-vehicle load is provided with a first communication processing module. The measuring and controlling transceiver is provided with a second communication processing module. An emergency channel which is independent from the bas exists between the first communication processing module and the second communication processing module. Through the emergency channel, data transmission can be performed among ground, the on-vehicle load and the transceiver, thereby reducing a task executing risk of the aerospace vehicle. The invention further relates to a telemetering method of the aerospace vehicle.

Description

technical field [0001] The invention relates to an aerospace vehicle. [0002] The invention also relates to a telemetry method for an aerospace vehicle. Background technique [0003] For traditional satellites, the on-board load is managed by the on-board computer. The ground relies on the on-board computer to transmit the data from the on-board payload to the ground through the on-board measurement and control transceiver through the on-board measurement and control transceiver. [0004] The ground controls the payload on the star by sending indirect commands and direct commands. The indirect instructions are distributed by the on-board computer to indirectly control the on-board load, but there are certain risks in the indirect instructions. Indirect command is the main means for the ground to control the payload on the star or manage the data. Indirect instructions are received by the on-board measurement and control transceiver, transmitted via the on-board bus, dec...
