Features & Capabilities

GPS Diagnostic: Satellite Test is an essential GNSS diagnostic tool for iPhone and iPad. It provides a Lodestone Chart with four bars, fast GPS lock, and precise latitude, longitude, altitude, speed, and heading data from the internal GNSS receivers. It works offline, supports imperial, metric, and nautical units, and helps diagnose why a location may not be available, while aiding you in obtaining reliable positioning for navigation apps.

Upgrade with COORDINATES-PRO IAP to access USNG, MGRS, UTM, OSNG, GEOREF, GARS, and 174 datums, expanding compatibility with maps used by civilians, the military, and NATO. The app has a smaller footprint (now about 35 MB), offers free email support, and is ideal for navigators, yachtsmen, pilots, and developers who need precise GNSS data.

Just got a new-to-me iPad to use iNavX at a better size than my phone. Panicked when that and map apps, barometer nor any gps apps were working. Read the reviews, downloaded this to find that this little old(er) tablet needs a clearer view of the sky to find satellites than my iPhone does. iNavX is happy now - I am where it thinks I am. Still gonna keep this open right beside the nav app because I can see what this is doing. Excellent app - Thank You!

Got the app and had a question. Emailed David and he responded immediately to help me figure out my GPS issue.
