Time setting from GPS is a great fringe benefit, but the original idea here was to develop a simple interface for a generic GPS receiver to display Position, Velocity and Time. This would form the basis of a diagnostic capability for an Empeg/GPS system in advance of having the software for a full blown navigation system available.

Once we have time available then using it to limit the drift of the Empeg's time keeping could follow. Not all receivers provide a discrete 1 pps signal and getting it into the empeg would involve "borrowing" another input, such as the Headlight Sense or Mute. By using the time stamps available from the serial data stream with a little bit of calibration we should be able to have time accurate to within a second.

Anything you would care to contribute to this cause would certainly be welcome.
