Dawn Technology has announced a new version of their GPS system, the di-GPS Mini 3L. The big new feature is the ability to provide a GPS position at power-on (last fixed position). That means that all your pictures will be tagged with a position in the EXIF, though that position may not be accurate if you've moved since the last satellite acquisition. Dawn has versions for the 10-pin connector cameras as well as the D90 and D5000.
