Loop Filters with Controllable Doppler Jitter for Standard and High Sensitivity GNSS Receivers

Standard tracking loops are usually designed by selecting the loop bandwidth that controls the variance of the phase observable. In this paper, a new approach for the loop filter design is introduced. The proposed methodology is based on the concept of Doppler bandwidth and provides control over the variance of Doppler frequency measurements. Doppler measurements reflect the relative motion between receiver and satellites and can be used to simplify the selection of the loop parameters that can be directly determined as a function of the user dynamics. Two different GNSS carrier tracking loop architectures are considered, namely standard and memory discriminator based tracking loops, and a design example is provided to show the effectiveness of the proposed approach.
