Pseudorange Inter-Frequency Biases
The figures below show the nominal receiver pseudorange inter-frequency biases (IFB) as a function of
the carrier frequency. The bias at the L1/E1 carrier frequency (1575.42MHz) is taken as a reference and
is therefore arbitrarily set to 0. The red dots mark the frequency of common GNSS carriers. The figures
only account for the receiver IFBs, and do not include any biases in the antenna or splitter.
