DATATYPE_NAV_MODEL_PREDICTIONS_GPS payload
Payload in XML format
If you have requested DATATYPE_NAV_MODEL_PREDICTIONS_GPS data from HERE GNSS API, you get a response where Message.data.data_type is DATATYPE_NAV_MODEL_PREDICTIONS_GPS and the predictions are in Message.data.payload.
The payload contains 168 A-GNSS-ProvideAssistanceData elements. Each of the elements contains predicted navigation models for GPS satellites for consecutive two-hour periods. Together, they provide navigations models for 14 days.
The XML in the example has been created by first decoding the LPP data in payload and then encoding it to XML format. Data is shown only for the first two satellites.
