At least the data collection part is very easy to set up on Android and zero maintenance afterwards: Use GPSLogger[1] to record the position. It can auto-upload to pretty much anything from DropBox to SFTP (FTP over SSH). It can auto-start on boot, run in background, and rotate files daily. (If you do SFTP, use ForceCommand internal-sftp in sshd_config to restrict the phone to file transfers.) No excessive energy usage. Use GPSMapper[2] to visualize the GPX files on phone, or https://www.gpxsee.org/ https://www.gpxsee.org/ on Linux (this tool works well even with hundreds of GPX files loaded, unlike all others I've tried). None of the viewers are really "nice" unfortunately. If someone needs a side project idea, a personal location history visualizer would be nice. All existing tools focus on individual tracks (eg day hikes), there's nothing that does much useful when you dump a few years worth of history into it. Actually most just freeze or crash. But there's so much that could be done (performance, filtering by time, exporting/sharing specific parts, postprocessing like removing outliers, correcting cut corners by matching against a map, detecting places/businesses and hyperlinking to services like AllTrails, visualizations like speed over time (this part is common) but auto-detecting and showing this for all traces along the same route (no software does this yet) (think "how fast was I on which part of my commute each day over the past year"), multi user eg. family capability, etc.) Of course even if viewers are limited today, one can still collect the data in case someone writes a better viewer tomorrow ;-) Google Takeout can export raw location history, and there are tools to convert that standard GPX. Only issue I have with GPSLogger is that the accuracy filter is not adaptive. At a high value, you'll get outliers, at a low value, it won't record during flights.
