High-adaptability aerospace craft program design method, spaceborne computer and aerospace craft

Abstract

The invention discloses a high-adaptability aerospace craft program design method, a spaceborne computer and an aerospace craft, and the method comprises the steps: S1, not embedding flight program content in satellite service software, setting a flight program which needs a satellite to autonomously run according to time as a program control instruction which is sequentially executed according to a time sequence, storing the program control instruction set into a first memory of a spaceborne computer; storing the satellite service software program into a second memory of the satellite-borne computer; and S2, synchronously and respectively debugging, verifying and upgrading the flight program and the satellite service software. According to the method, the autonomous operation of the satellite according to the flight program is realized based on the program control instruction set, and the design iteration of the flight program and the whole development process of the whole satellite are performed in parallel, so that the period and the cost are greatly reduced, the use requirements of the low-orbit satellite giant constellation are fully adapted, and a foundation is laid for better establishment of the low-orbit satellite giant constellation.

Description

technical field [0001] The invention relates to the field of satellite software design, in particular to a highly adaptable aerospace vehicle program design method, an on-board computer and the aerospace vehicle. Background technique [0002] In order to meet the world's ever-growing demand for satellite network access, especially to solve the problem of Internet access in rural and ocean-going areas, both at home and abroad are actively exploring and developing satellite Internet services, especially low-orbit satellite constellations, which have global Internet access. input ability. The low-orbit satellite constellations aimed at commercial applications are all configured as giant constellations in order to achieve global coverage without dead ends. Among them, SpaceX’s Starlink plan has completed 17 batches of 1015 satellite launches as of January 21, 2021. The entire system construction plan is 4.2 Ten thousand satellites, the launch plan far exceeds that of traditiona...

Problems solved by technology

At present, most cube satellite and small satellite projects have begun to adopt the "one-step-to-prototype" design scheme, which greatly reduces the development cycle and cost, but the development cycle of the prototype stage is still relatively long, especially for the on-board computer and satellite affairs software. Development usually takes 4 to 6 months, which is at least 1 to 2 months longer than the development cycle of other satellite components at the same stage. Because traditional satellites usually solidify the flight program and star software, the flight program undergoes desktop joint testing. In the end, the star mission software is often iteratively updated, and any change in the flight program and star mission software needs to be reprogrammed, resulting in a waste of time and cost.

In addition, low-orbit satellites often have a short design life. During the long-term operation of the constellation, new satellites need to be launched in time to replace and supplement the faulty satellites, and satellites are also required to have a short development cycle.
