Code bias overview

The table below lists the currently available code bias LPP signals, and the GNSS signals that have been used to calculate each value. The table will be updated in the future when support for new signals is added.

When searching for a code bias to use with a signal, use the exact matching one, if it is available. Otherwise, use one that matches the particular system and frequency. Even this type of match improves accuracy and is better than the alternative of not using a code bias at all.

The tracking modes that are used to derive a code bias are marked with RINEX notation (observation codes).
