Abstract
A method for enhancing data wipeoff by predicting future navigation data. Data wipeoff using predicted future navigation data reduces or eliminates incomplete data wipeoff, thereby enhancing GPS receiver sensitivity and reducing acquisition times. Predicting future navigation data involves receiving navigation data and using the received navigation data to generate predicted future navigation data, wherein the predicted future navigation data should be approximately identical to navigation data received at a future time. The predicted future navigation data is subsequently used to perform data wipeoff.
Claims20
A method of predicting future navigation data comprising the steps of:
- receiving navigation data;
- and
- predicting the future navigation data using the received navigation data, wherein predicting the future navigation data includes determining a future time of week message corresponding to an action time using a received time of week message in the received navigation data.
A method of performing data wipeoff comprising the steps of:
- receiving future navigation data and an action time, wherein the future navigation data includes a future time of week message corresponding to an action time based on past navigation data;
- and
- performing data wipeoff using the future navigation data at the action time.
