Abstract
A combination of a GPS device and an adjacent mobile communications device. The mobile communications device comprises: a wireless communications transceiver comprising means for receiving at least one of timing information and location information. The GPS device comprises: a receiver for receiving at least one GPS signal, a positional estimator for providing a positional estimate in dependence of said received at least one GPS signal and said at least one of timing information and location information.

A mobile communications device comprising:
- a wireless transceiver comprising means for receiving at least one of timing information and location information from a cellular communications network, and
- a second wireless transceiver comprising means for transmitting said at least one of the said timing information and location information to an adjacent GPS device.
A GPS device comprising:
- a GPS receiver comprising means for receiving a GPS signal;
- a wireless transceiver comprising means for receiving from an adjacent device at least one of timing information and location information;
- and
- a GPS positional estimator for providing a positional estimate dependent on said received GPS signal and at least one of the said timing information and location information.
A method of providing a GPS estimate comprising the steps of:
- receiving a GPS signal on a GPS device;
- receiving at least one of timing information and location information from a cellular communications network on an mobile communications device, the mobile communications device being located at substantially the same location as the GPS device;
- producing a further signal dependent on the said timing information and location information signal;
- transmitting the further signal over a wireless communications link to the GPS device;
- determining a positional estimate dependent on the received GPS signal and the third signal on the GPS device
