DATATYPE_BSX payload

Payload in BSX (Bias Solution INdependent EXchange Format (Bias-SINEX)) format

If you have requested DATATYPE_BSX data from HERE GNSS API, you get a response where Message.data.data_type is DATATYPE_BSX and data is in Message.data.payload.

The contents of the payload is differential code bias (DCB) data in the Bias-SINEX 1.00 format, which is a text format.

The example below has been created by saving the beginning of the payload to a file. The full length of the DCB information is 265 kB.

- Daily multi-GNSS differential code biases (DCBs) are derived from observations
  of MGEX/iGMAS networks with local ionospheric TEC modeling technique entitled
  MGTS. A description of MGTS algorithms is provided in
     Wang N., Yuan Y., Li Z., Montenbruck O., Tan B. (2016)
     Determination of differential code biases with multi-GNSS observations,

- A zero-mean constellation condition is applied to separate satellite and
  receiver biases on a daily basis.
