Multi-source data flow control system suitable for double-satellite injection

Abstract

The invention provides a multi-source data flow control system suitable for double-satellite injection. The multi-source data flow control system comprises a combination formed by a first satellite and a second satellite. The first satellite comprises a first computer and a second computer, and the second satellite comprises a third computer and a fourth computer; the first computer and the second computer are in communication connection through a wired channel; the third computer and the fourth computer are in communication connection through a wired channel; the first computer and the third computer are in communication connection through a wired channel; and the second computer and the fourth computer are in communication connection through a wired channel. According to the dual-satellite combined orbit injection task characteristics, combination satellite-ground telemetry and remote control, inter-satellite and in-satellite measurement and control data packaging and addressing modes are normalized; multi-point access and multi-route transmission of combined satellite-ground telemetering and remote control are realized by using satellite-borne measurement and control system resources of the two; a plurality of data interaction physical channels forming a ring topology are arranged between two satellites, and data redirection between links is supported.

Description

technical field [0001] The present invention relates to the field of satellite data management, especially multi-point access, multi-route transmission, multi-priority concurrency, and integrated data flow control technology between satellites, satellites and satellites . In more detail, the present invention relates to a multi-source data flow control system adapted to double-star orbiting. Background technique [0002] Generally, satellites with GEO, MEO or IGSO mission orbits use the main body to carry apogee engines, and the power attitude control and data management of orbit transfers are independently completed by the satellites; rail load. However, in the way that the double-star combination transfers into the target orbit, the above-mentioned work of the combination is completed by the two-star collaboration. It is necessary to adopt a coordinated and unified method for the two-star collaborative data management, and to make full use of the resources on the two sta...
