  • Compared with centralized direct position determination, distributed direct position determination algorithm has the advantages of low computational complexity and low communication cost, but it has the problem of location accuracy loss. This paper proposes a distributed direct position determination technique based on the VEPPSO-EXTRA hybrid algorithm. Firstly, based on the direct position determination algorithm of subspace fusion, a distributed optimization model is derived; Secondly, based on the idea of multi-population joint evolution, a Vector Evaluation based Parallel Particle Swarm Optimization (VEPPSO) algorithm is proposed to achieve global optimization, and the initial value of the emitter iteration is obtained; Finally, the distributed Exact First-Order Algorithnm (EXTRA) is introduced to solve the final position to reduce the accuracy loss caused by distributed computing. The experimental results show that compared with the existing distributed direct position determination algorithm, this technology can solve the problem of location accuracy loss, and its computational complexity and communication cost are lower than the corresponding centralized direct position determination algorithm.
