Embodiment Construction

[0019] The present invention will be further elaborated below by describing a preferred specific embodiment in detail with reference to the accompanying drawings.

[0020] like figure 1 As shown, a fast track simulation system based on offline data includes: an ultra-real-time simulation subsystem and a semi-physical simulation subsystem; wherein the ultra-real-time simulation subsystem includes: a strategy generation module, a high-precision track simulation module, a simulation Data generation storage module;

[0021] Among them, the strategy generation module uses the overtime real simulation method of fast large-step simulation, and according to the initial orbit information and target orbit information, pre-determines in-plane, out-of-plane, and in-plane combined orbit control methods, and the number of control groups (the size of the control amount) and control sequence, the last group is required to be fine control to ensure the track control accuracy index (small cont...

Abstract

The invention discloses a fast track simulation system and method based on off-line data, which includes: using the result data of on-track actual measurement or test simulation, and according to the track control requirements, a 1:1 semi-physical simulation test is performed on the track control process , for the orbit control transition process such as the stable stage, the method of super real-time fast simulation is adopted. Through the stage division of the orbit control process, the semi-physical simulation test resources are concentrated in the orbit control stage, and the ultra-real-time simulation is concentrated in the orbit control waiting stage, which not only ensures the continuity of the test, but also improves the long-term orbit simulation test. efficiency.

Description

technical field [0001] The invention relates to satellite orbit simulation testing technology, in particular to a fast orbit simulation system and method based on offline data. Background technique [0002] The semi-physical simulation method of the spacecraft orbit is to collect the working state of the propulsion mechanism, bring the acquisition results and calculate the orbit information of the spacecraft in real time. With the gradual improvement of spacecraft functions and requirements, the orbit control of multi-satellite formations becomes more and more complex, and the completion of a complete orbit control cycle is long, which may last for 5 to 15 days, while the semi-physical simulation test verification test generally lasts for a period of time. within 8 hours. Therefore, the long-period orbit control brings difficulties to the semi-physical simulation test and verification test work, resulting in low test efficiency and increased simulation cost.
