Store description excerpt
See where you are, how good the fix is, and which GPS satellites should be overhead, predicted from public orbit data. SATELLITE SKY MAP A polar chart places the GPS constellation above you, computed from the public GPS almanac (US Coast Guard / CelesTrak) propagated with the standard orbit equations for your position and the current time. It is refreshed weekly and works offline from a bundled copy. These are PREDICTED positions, and the app labels them as such on screen. iOS gives apps no per-satellite data at all — no live signal strengths, no which-satellite-is-in-use, and no GLONASS or Galileo. What you see is where the GPS satellites actually are, not what your receiver is hearing from them. POSITION AND FIX QUALITY • Latitude and longitude, in your choice of format • Accuracy in metres with a plain quality rating • Altitude, ground speed and course • A gauge that tells you at a glance whether the fix is worth trusting WAYPOINTS Save a spot, navigate back to it with distance and bearing, and get an arrival alert. Export the lot as CSV or GPX. LOCK SCREEN CARD While the app is open, a Live Activity shows accuracy, altitude and speed on the Lock Screen and in the Dynamic Island. It cannot keep updating once the phone is locked — this app does not run location in the background — so it marks itself PAUSED rather than leaving a stale reading looking current. WHO USES IT Hikers and paddlers checking fix quality before relying on it · paragliding and drone pilots · surveyors wanting a quick accuracy read · anyone curious what is overhead right now Available in 25 languages.
