1. IntroductionThe theoretical shape of a chip in GNSS receivers is assumed to be rectangular. However, in practice, the actual shape is distorted, leading to biases in pseudorange measurements [1]. Numerous studies have demonstrated a correlation between these biases, the chip’s shape, and the correlators used [2]. This bias, known as the signal distortion bias (SDB), is defined as the time difference between the distorted chip and the ideal rectangular chip.
