Self-interference can cause large errors of up to tens of meters on the GPS C/A code pseudorange measurement. Although the probability of an occurrence of large self-interference errors is small, to enable the use of C/A code phase measurements in hi

INTRODUCTION A core aspect of Global Navigation Satellite Systems (GNSSs) is the time scale they use to operate. Since they use independent time scales, inter-system time-offsets are one of the most significant biases to be taken into account in a mu
