GPS Test Satellite Tracker vs GPS Info Telemetry

GPS Test Satellite Tracker combines a live satellite radar with a real GPS/GNSS status screen and a GPS accuracy test. RADAR Track Starlink, the ISS, navigation satellites, communication satellites and other orbital objects on a compass radar, positioned relative to your location. Satellite positions are predicted from public orbital data (TLE) using the SGP4 model. GPS / GNSS STATUS See your device's real GPS fix from iOS — position, altitude, speed and location accuracy. Alongside it, view the navigation satellites (GPS, Galileo, GLONASS, BeiDou, QZSS, SBAS and NavIC) calculated to be above your horizon, split into "in use" and "in view," with signal estimated from elevation. Because iOS does not expose the receiver's raw satellite list, the satellite view is computed from orbit data — while your position and accuracy are the device's real values. ACCURACY TEST Leave your device still for 1, 5 or 10 minutes and see how steady its position really is. Every fix is plotted on a scatter chart with CEP50 and CEP95 circles, alongside RMS, 2DRMS, maximum drift and height statistics. Measure against the session average or against a known coordinate, and compare the accuracy iOS reports with the scatter actually measured. The test uses iOS system positioning (Core Location), not raw GNSS measurements. COORDINATES Show your position in decimal degrees, degrees and minutes, or DMS. With Pro, use UTM, MGRS, USNG, GEOREF or Gauss-Krüger grids, on the WGS84, SK-42, ED50 or NAD27 datums, so a reading can match the paper map in your hand. Datum conversions are approximate; do not rely on them for navigation. Send your position as a full report or a one-line SMS from the iOS share sheet.
