A parallel navigation computation algorithm with a single update frequency was proposed and analyzed to increase the navigation computation updating rate in high dynamic conditions. The parallel algorithm includes 4 parallel computation modules: the parallel attitude computation module, the parallel velocity computation module, the parallel position computation module, and the parallel parameter computation module. The computation speed analysis shows that the total implement periods of the parallel algorithm are about 6% of conventional algorithms. The results of FPGA-based experiment show that the design significantly increases the updating rate of the navigation computation, thus greatly benefiting the navigation accuracy in high dynamic conditions.
