N2 - Multipath interference is the most serious problem that causes GNSS receiver tracking error to be difficult to eliminate. In order to solve the problem of weak mitigation performance for short time delay multipath in traditional receiver, we construct a modified Double-Delta phase discriminator by adding a certain compensation factor in the traditional discriminator formula, which uses two sets of early-late correlators and a prompt correlator. In order to consider the general situation, we use the TK operator as detection module to construct a new multipath suppression strategy in combination with the modified Double-Delta phase discriminator, and put forward the implementation procedure of this algorithm. The results show that this strategy has a better mitigation performance to the short time in-phase delay multipath signals without affecting suppression performance to middle and long time delay multipath signals.
