Variability of GPS/GLONASS differential code biases

Variability of GPS/GLONASS differential code biases

While estimating ionospheric total electron content (TEC) using both pseudorange and phase GPS/GLONASS data, there occurs a systematic error caused by the difference in processing times of L1 and L2 signals through radio frequency paths of satellites and receivers, known as differential code biases...
