GDOP Bounds for GNSS Augmented with Range Information
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2017 Code phase GNSS receivers convert the measured satellite pseudoranges into estimates of the position and clock offset of the receiver, typically via an iterative, linearized least squares method. Since the pseudoranges themselves are noisy, the resulting estimates of position and time are random variables.
