GNSS RECEIVER WITH WIRELESS INTERFACE
First Claim
1. A GNSS receiver (50), including a RF front-end (510), a signal processor (520) and a navigation engine (525) arranged to compute position data representing the receiver'"'"'s location, based on radio signals received from radiolocalization satellites, the GNSS receiver further including a wireless interface (55) for communicating the position data to a host system (40), characterized in that the communication between the wireless interface (55) and other components of the receiver (50) is bidirectional.

Abstract
A wireless GNSS receiver, for example a Bluetooth® receiver, including a bidirectional link to the host, and an update client, for downloading extended ephemeris data from the host, by the Bluetooth® link. The invention reuses the protocol used for NMEA data transfer, in order to send the extended ephemeris data up to the receiver. Hence, the extended ephemeris data can be sent without having to instantiate any other type of connection to the receiver. The invention reduces the cost and complexity of BT-GPS receivers that want to make use of extended ephemeris technology in order to reduce the time to first fix of GPS receivers left off for more than four hours.
