Does the iSTAR Fusion have GPS? What about a compass?

No. iSTAR Fusion does not feature built in GPS, but it does have a digital compass.

You can however supply an external GPS feed into iSTAR via the USB port. Simply ensure the GPS device you are using can supply a 4800 Baud NMEA data stream.

We use this device for geotagging our iSTAR Fusion images.
