What about a computer vision system that uses the stars and the sun to determine location? I imagine that such a device would need an accelerometer to determine it's orientation relative to the horizon and a decent sensor with normal prime lens (focal length equal to diagonal dimension of sensor)
A temperature and pressure sensor may also be useful because so long as the calendar is set correctly, the system could narrow down it's possible locations by comparing actual temperature and pressure with a database of historical highs and lows.
I would imagine any approach using the stars in the sky would be extremely accurate. It only needs batteries and access to solar power to remain functional.
What other sensor data would be valuable to help infer geolocation? Magnetometer?

But only on a clear night. Pressure would be okay for determining altitude, but that's it. Temp and pressure are so wildly variable that it would be a thoroughly useless metric for determining position. Not to mention that there simply aren't databases of historical temperature data for random expanses of Pacific Ocean.
