Position: the Fix line (or how long it has been searching), latitude and longitude in decimal degrees or degrees-minutes-seconds (Settings -> Coordinates), the Maidenhead locator, altitude, speed and course, HDOP and UTC. Sky: the satellites by azimuth and elevation, coloured by constellation, filled when used in the Fix, with used/in-view counts. Tab switches. lib/gnss/geo_format holds the formatting, the locator and the sky projection, host-tested (6 tests; locators checked against FN31pr and JN58td). Verified on the device by a window: 3D Fix from GPS, GLONASS, Galileo and BeiDou.
