Abstract

The invention provides an LEO-to-HEO multi-orbit satellite measurement and control system and method. The LEO-to-HEO multi-orbit satellite measurement and control system comprises an orbit measurementmodule, a first telemetry module, a second telemetry module and a remote control module. The orbit measurement module is configured in a mode of combining USB (Universal Serial Bus) orbit measurementwith GNSS (Global Navigation Satellite System) orbit measurement. The remote control module is configured to realize global beam coverage by combining two pairs of measurement and control transceiverantennas and receive remote control signals in all track operation phases. The first telemetry module is configured to realize global beam coverage by combining the two pairs of measurement and control transceiver antennas and transmit low-power telemetry signals in the LEO orbital phase and the early orbit transfer phase. The second telemetry module is configured to achieve hemispherical beam coverage in a single-antenna transmitting mode, achieve time-sharing global beam coverage through switching of two measurement and control transmitting antennas and transmit high-power telemetry signalsin the later orbit transfer phase and the HEO orbital phase.

Description

technical field [0001] The invention relates to the technical field of observation satellites, in particular to a LEO to HEO multi-orbit satellite measurement and control system and method. Background technique [0002] In recent years, my country has launched a series of space science astronomical observation satellite engineering projects, and actively cooperates with international (mainly represented by the European Space Agency ESA) to jointly expand the boundaries of human cognition of space astronomy. For example, SVOM satellite, EP satellite, ASOS satellite, MIT constellation, SMILE (Solar wind MagnetosphereIonosphere Link Explorer, SMILE for short) satellite, etc. Some of the satellite scientific observation missions need to be from low earth orbit (LEO) to high elliptical orbit (HEO), such as: magnetosphere-ionosphere-thermosphere coupling small satellite constellation exploration plan (MIT constellation for short), the satellite working orbit is controlled by LEO ...
