Contrastive analysis on cooperation and non-cooperation models for location and velocity measurement by multiple satellites to earth objects

Abstract:

The application of location and velocity measurement by multiple satellites to earth objects is very important. The intrinsic relationship for location model between satellite electronic reconnaissance and Global Navigation Satellite System(GNSS) is firstly analyzed. The non-cooperation velocity measurement model for radiation objects through the multiple electronic reconnaissance satellites is naturally established based on the GNSS principle. Then the instance is further discussed when the number of satellite decreases to three. The simulations demonstrate that the velocity precision about 5 m/s is acquired on condition of frequency difference of 2 Hz. This is an important reference for radiation object velocity measurement application by the electronic reconnaissance satellites.
