Abstract :
Multi-satellite systems can be used for high accuracy position of emitters, but systems might be complex. Dual-satellite positioning systems based on TDOA and FDOA joint estimation have discussed. The algorithm model has been established and the solving process has been given. Positioning performance analysis of the systems with variable parameters proves that such systems can achieve high accuracy position with only two satellites. Dual-satellite positioning systems will be a promising scheme.
