Complete, simple, easy to use & free application for Land Surveying, Topography, Bathymetry & GIS. Suitable for Geodesy Engineering, Civil Engineering, Geology and other disciplines related to maps, coordinates, location, address and spatial analysis. Can be used as a tool in determining position, coordinates, location & address, area & distance measurement, simple spatial analysis such as Overlay, Buffering and finding coordinate location on the field / stake out. Map Coordinates: Can be used to obtain Latitude Longitude, UTM, MGRS and other Coordinate Reference System using EPSG Codes in real time. Plot points complete with coordinate data, addresses, notes, photo and MSL elevation (premium). Export saved points to CSV, DXF or KML files. Offline GPS: Used to get coordinates in an offline state (without internet access), your cellphone will function like a Handheld GPS to get Latitude Longitude coordinates, UTM, MGRS, Elevation (ellipsoid), MSL Elevation (geoid), accuracy and other useful information. Coordinates data can be stored in an unlimited number inside your databases, given notes / labels, photos or exported into CSV files. Contours: Module to generate contours based on number of contour lines, desired elevation or contour interval. This is premium module and need internet connection. Coordinates Converter: To convert coordinates manually from Latitude Longitude to UTM & MGRS and vice versa. It can also be used to convert Addresses to Coordinates (Geocoding). Area/Distance: Used to measure distance and area with various units (support units: m, km, ft, miles, hectare, acre), register lines / polygons, make polygons automatically from measure points using sophisticated Convex Hull, Concave Hull or Trace ID methods. Create polygon holes manually or automatically from covered polygons. Automatically repair invalid geometry / self-crossing polygons, and much more. You can store unlimited lines / polygons in your database, displayed on a map, add photos and labels or exported to CSV or KML files. This module also includes spatial editing algorithms like Snap Nearest, Delete Object Inside or Outside Polygon. Buffer/Overlay: Simple GIS module to perform spatial analysis such as buffering & overlays (and other GIS operations) with several options including Union, Intersection, Difference and Symmetrical Difference. Already support negative buffer for polygons. Find Point: Module to find a location or coordinates in the field / Stake Out using built in GPS and Compass on your cell phone. Compass Map: Module with Maps, Compass, Distance and Azimuth to assist navigation and stake out on the field. Elevation Profile: Premium module to create simple Elevation Profile, this module needs internet connection. Bubble Level module: measuring tool to calculate leveling, degree of slope and percentage of slope. DTM Module: generating TIN (Triangulated Irregular Network / Delaunay Triangulation) DTM from random points or existing contour data, calculating cut and fill volumes (including determining the optimal cut-and-fill reference level where volumes are nearly balanced), performing contour interpolation, etc.. Some other modules. Any suggestions are welcome, please submit via email to utmgeomapapp@gmail.com or write a review. Thanks.

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. FEATURES - Live satellite radar for Starlink, ISS and orbital objects - Real GPS fix quality, accuracy and location data - GNSS satellites overhead: in use vs in view - Stationary GPS accuracy test with CEP50 / CEP95 and scatter plot - Full orbit track and telemetry for any satellite - Signal indicators, NORAD IDs, footprint, altitude and more Terms of Use (EULA): https://developer-barseghyan.github.io/satellite-tracker-support/terms Privacy Policy: https://developer-barseghyan.github.io/satellite-tracker-support/privacy

Verdict

The call

The clearest difference is review sentiment: UTM Geo Map Y2Tech at 100% against GPS Test Satellite Tracker's 50%. UTM Geo Map Y2Tech also leads on update cadence (fortnightly vs every 3 months) and rating (3.8 vs 3.5). GPS Test Satellite Tracker's advantage is ads (none vs shown). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
