Abstract

The invention discloses a radiation electromagnetic compatibility test method for an electric propulsion system and on-star radio frequency equipment. Firstly, an ion thruster is arranged in a wave transmitting secondary cabin; the wave transmitting secondary cabin is connected with a main vacuum tank; and electromagnetic radiation interference produced by a plume of the ion thruster is emitted out of the main vacuum tank through the wave transmitting secondary cabin. Each equipment and antenna are connected. When the electric propulsion system is started to normally work, both uplink level and downlink level of a responder are weak levels; conditions of uplink instruction reception and downlink remote metering error code are checked; if the instruction reception is correct, the code ratemeets the requirement and the responder is not interfered; remote metering parameters for a GPS (Global Positioning System) receiver are observed, and absolute positioning condition and relative positioning condition are determined; and if the remote metering is correct and the positioning is normal, the GPS receiver is not interfered.

Description

technical field [0001] The invention relates to an electromagnetic compatibility test method of an electric propulsion system, in particular to a radiation electromagnetic compatibility test method of the electric propulsion system and on-board radio frequency equipment. Background technique [0002] Since the satellite electric propulsion system has high voltage, high current, large voltage or current change rate, and complex plasma environment, the radiation emission electromagnetic interference generated by the electric propulsion system will cause serious damage to the radio frequency equipment on the satellite. potential impact. These radiated electromagnetic interferences may come from the power distribution management unit (PPU), cables, electric thrusters, and emissions in the extraction plume. The electric propulsion system and the on-board radio frequency equipment must ensure electromagnetic compatibility, so the radiation electromagnetic compatibility verificati...
