A professional calculation method for specific alignment calculation is introduced into the genetic algorithm, which makes the initial value setting of the genetic algorithm more reasonable. The invalid search space can be cut down in the genetic iteration calculation, avoiding a large number of invalid iteration calculations. In this way, the advantages of strong optimization ability of genetic algorithm are preserved, and the disadvantages of blindness and large amount of calculation in probability search of genetic algorithm are overcome. Not only the search efficiency is improved, the calculation amount of genetic search is reduced, the calculation speed is improved, but also the advantages of optimization calculation of genetic algorithm can be used to improve the accuracy of alignment calculation results. Simulate the trajectory of the carrier during takeoff and ascent and the output parameters of gyroscope and accelerometer, and simulate the heuristic genetic algorithm. The results show that the genetic algorithm with initial value heuristic can quickly complete the search calculation, and the calculation results can also meet the accuracy requirements of initial alignment. 收起
