Abstract
A method of last known position reporting in a device is disclosed. The method generally includes the steps of (A) generating a request signal in an application module of the device, the request signal requesting a current position of the device while a plurality of navigation signals are too weak to calculate the current position, (B) calculating a sequence of known positions in a position module of the device, the known positions being calculated based on the navigation signals with sufficient strength, (C) calculating the current position in the position module in response to the request signal, the current position being calculated based on a last of the known positions and (D) generating a position signal in the position module, the position signal reporting the current position as a valid position to the application module.
