Predicted GNSS Assistance Data

Predicted GNSS assistance data contains the predicted navigation models (orbit and clock) for several days in future.

HERE GNSS API provides predicted navigation models for:

  • 14 days for GPS and Glonass
  • 7 days for Galileo and Beidou.

Using stored predicted navigation models allows the device to shorten TTFF also when it does not have data connection.

The format of GNSS assistance is described in Data Types / Predicted GNSS Assistance Data.
