Abstract

The joint tactical information distribution system (JTIDS) achieves relative navigation function, but the random errors caused by position of message source influence the performance of navigation in navigation calculation. In view of this problem, CLRB's expression was deduced under the circumstance of relative navigation of JTIDS, and aquantitative analysis was made on the effect of the source location's errors on navigation calculation. Moreover, a two-step least-square algorithm of position determination was used so as to eliminate errors of the source location. Simulation results show that the source location's errors affect much on navigation calculation, therefore, the algorithm in this paper will effectively restrain the source location's errors.

Key words： JTIDS; relative navigation; source position random errors
