摘要：

This paper proposes a novel anti-jam navigation system based on A-GNSS. In such a system, receivers can benefit from the assistance in the improvement of acquisition time, BER, anti-jam performance in narrowband and wideband noise jam, and a low cost of implementation. With the assistance of this system, total search space of the receiver can be decreased to 0.041% of the origin one. When JSR of the wideband noise is 40dB, the signal of navigation satellites can still be acquired by the receiver, and the BER remains 0. The antenna array is merely required in the base station, offering fine time aiding, fine frequency aiding and authentic data assistances to all receivers in a certain area.
