Abstract: In the system of relative position and attitude determination based on wireless technology, the relative states autonomous determination of three satellites formation is studied. Using parameter adjustment, matrix is singular to working precision because observation geometry is very weak. In order to resolve this problem, a new method based on weighted partial parameters adjustment to get relative position and attitude information is gived. Firstly, the system model is built. Then weighted partial parameters adjustment compares with parameter adjustment. Lastly, the result of simulation is analyzed. The results show that the relative states of three satellites formation are autonomously determinate through using the method based on weighted partial parameters adjustment.
