If someone can help with the video matching this dev has been very into projects like this and I think would enjoy being part of the first 'sextant' phone https://github.com/kenyoung
That is a really cool idea, and MIGHT be practical. In the mean time, how about inputting a rough fix manually? I usually know my lat and lon to the nearest degree, or closer. It wouldn't bother me at all to type in 64N, 145W each time I turn on the GPS.
Are you proposing a manual-entry location provider for geoclue so that apps see the location you entered manually?
Here's a practical example of using an iPhone as a sextant. Note the extra optics required, and the limitation of sensor accuracy, but still better than nothing.
