Tomstrails GPS UTM vs GPS Test Satellite Tracker

GPS UTM displays a fast and accurate UTM grid reference. Locate your position on topographic maps. GPS UTM supports many of the regional datums used around the world including ED50. ∙ No phone signal required - works in the most remote locations. ∙ 1 metre, 10 metre and 100 metre formats. ∙ Paste your coordinate into other apps or share with other people. ∙ A large, clear, high contrast display ensures you can easily read your position in any light conditions. ∙ Optimal battery use based on speed of travel and current charge level ensures all day use. ∙ No Adverts. GPS UTM - know where you are.

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.
