Although Instinct 2X Solar ist very precise, I encountered data far off the real track. The facts:
In the skiing area of Zermatt there is a cable car that runs like a metro. To enter the lower station from the slopes you take an elevator down. Than the train makes 700 m in altitude. At the upper station you take another elevator up an step out on a platform. There the satellite situation is somewhat complicated, however, to one side of the starting place you have 180° horizon free space. Within more than 20 correct measurements over 12 days, one measurement recorded the track between upper station and lower station (elevator), 3000 m long, about 1 km off the right position, systematically. See the screenshot.
If you cut out the blue track in a picture editor and move it in the indicated direction, it fits onto the accumulated red tracks. There is a small angle of less than 5° involved as well.
What has happened?
