Complete 50 bps Navigation Message

For assisted-GPS (A-GPS), E-911, and other applications requiring weak-signal acquisition-aiding techniques, the GDGPS System provides a global 50 bps navigation data product, containing the 50 bps navigation data stream from all transmitting GPS satellites.

The multiply-redundant GDGPS tracking network enables majority voting schemes to ensure the integrity of this product, where every bit counts. This product is available redundantly from all three GDGPS Operations Centers (GOCs).
