Satellite Navigation - GPS - How It Works | Federal Aviation Administration
2 weeks ago - Satellite Navigation is based on a global network of satellites that transmit radio signals from medium earth orbit. Users of Satellite Navigation are most familiar with the 31 Global Positioning System (GPS) satellites developed and operated by the United States.
How many GPS satellites are in orbit?
The GPS constellation currently has 32 operational satellites in medium Earth orbit at approximately 20,200 km altitude, distributed across 6 orbital planes with 55° inclination. The constellation requires a minimum of 24 operational satellites.

What is the difference between GPS and GNSS?
GPS is one specific satellite navigation system operated by the US. GNSS (Global Navigation Satellite System) is the umbrella term for all navigation satellite systems including GPS (US), Galileo (EU), GLONASS (Russia), and BeiDou (China).

How accurate is GPS?
Standard GPS provides approximately 3–5 metre accuracy for civilian users. Dual-frequency receivers using L1 and L5 signals can achieve better than 1 metre accuracy. Military M-Code provides sub-metre accuracy with anti-jam capabilities.

r/nasa on Reddit: How does a phone's gps behave in space?
April 22, 2026 -
I was looking at the EXIF data for the Artemis II mission, especially the one shot on iPhone and wondered how the gps behaves in space, especially away from the earth and not in LEO, and what the phone would say if they had geotagging enabled.

GPS receivers work very well in LEO. In fact, they work a bit better than on the surface, due to the lack of atmospheric distortion. The GPS constellation is above LEO in MEO. They're even used in orbiters. JPL, for example has the GRACE series of formation flying spacecraft to measure Earth's gravity. Consumer-level GPS receivers turn themselves off by convention, a.k.a COCOM Limits . Above 59,000 feet and/or 1,000 knots. So for your specific question, a consumer phone wouldn't report GPS at all, unless they got a special firmware update to remove the COCOM limits. (Edit: Typo on altitude)

They probably put it on spaceship mode, I mean airplane mode.
