Embodiments of the present application provide a rocket flight navigation method, device, equipment, system and storage medium. The rocket flight navigation method, applied to the first processor, includes: receiving inertial group information; determining first navigation information according to the inertial group information; sending the first navigation information to the second processor, so that the second processor can navigate according to the first information and satellite positioning information to determine the second navigation information, and determine the correction information for the first navigation information according to the second navigation information; receive the correction information fed back by the second processor; determine the third navigation information according to the first navigation information and the correction information , and determine the flight control instruction according to the third navigation information. In the embodiment of the present application, the calculations related to the rocket's flight control are distributed to two processors at the physical layer for collaborative implementation, which can effectively enrich the computing resources, improve the computing power of complex algorithms, reduce the computing delay rate or shorten the duration of the computing delay, Thus, the flight control precision can be effectively improved.
Description
technical field [0001] The present application relates to the technical field of rocket flight, in particular, the present application relates to a rocket flight navigation method, device, equipment, system and storage medium. Background technique [0002] Rocket flight control usually includes navigation calculation, guidance calculation, attitude control calculation, and control signal output, and this series of calculations is usually implemented by the same processor at the physical layer. [0003] With the increasing accuracy of flight control, the types of related calculation formulas are becoming more and more numerous, and the amount of calculation is also increasing, which greatly increases the resource consumption of the processor. This not only puts forward higher requirements for the performance of the processor, but also leads to increased costs. Or it may be that the flight control accuracy is reduced due to insufficient processor resources, or it is difficult ...
