GPS Satellites are in MEO, so AFAIK, it's possible to get a GPS track in LEO -- assuming the receiver isn't artificially altitude and speed capped.

"In GPS technology, the term "COCOM Limits" also refers to a limit placed on GPS tracking devices that disables tracking when the device calculates that it is moving faster than 1,000 knots (1,900 km/h; 1,200 mph) at an altitude higher than 18,000 m (59,000 ft).[2] This was intended to prevent the use of GPS in intercontinental ballistic missile-like applications. Some manufacturers apply this limit only when both speed and altitude limits are reached, while other manufacturers disable tracking when either limit is reached. In the latter case, this causes some devices to refuse to operate in very high altitude balloons.[3]" https://en.wikipedia.org/wiki/Coordinating_Committee_for_Multilateral_Export_Controls https://en.wikipedia.org/wiki/Coordinating_Committee_for_Mul...
