GnssSignalBias2SinexBias

Convert GNSS signal biases from GROOPS format to IGS SINEX Bias format. Biases can be provided via transmitterBiases and/or receiverBiases. Phase biases without attribute (e.g. L1*) are automatically expanded so each code bias has a corresponding phase bias (Example: C1C, C1W, L1* are converted to C1C, C1W, L1C, L1W).

Time-variable biases (e.g. GPS L5 satellite phase bias) can be provided via timeVariableBias. Their time span will be based on the provided epochs ($t \pm \Delta t / 2$). The slope of the bias can be optionally provided in the second data column.

If GLONASS receiver biases depend on frequency number, those must be defined in inputfileTransmitterInfo to get the correct PRN/SVN assignment to the biases.

See IGS SINEX Bias format description for further details on header information.
