A Novel GNSS Carrier Tracking Loop Design Based on Fuzzy Logical Control
A differential phase error detector is inserted in the carrier loop structure for improving the dynamic performance of the loop in GNSS receiver in this paper. It is used to detect the abnormal phase jitter and amplify the adjusting increment for fast tracking. In order to avoid the differential detector amplifying noise interference in locking, fuzzy logical theory is introduced into the loop to control the amplification caused by the differential detector. Finally simulations show that the proposed design achieves high dynamic performance with effectively speeding up the tracking and widening the dynamic stress range.
