Global Position vs Great Circle Map

Turn your iPhone into a precision navigation instrument. Get coordinates in every major format, a compass, an altimeter, solar and lunar information, and a HUD speedometer. Your position readout continues working without a mobile-data signal. COORDINATES IN EVERY FORMAT Read your position instantly in: - Latitude and longitude in decimal degrees - Degrees and decimal minutes (DD-MM) - Degrees, minutes and seconds (DMS) - Radians - Universal Transverse Mercator (UTM) - Military Grid Reference System (MGRS) - Universal Polar Stereographic (UPS), for Arctic and Antarctic regions where UTM and MGRS are undefined Grid conversions run entirely on your device, so you can obtain a complete MGRS reference even on a ridge with no mobile signal. NAVIGATION TOOLS - Compass showing true and magnetic headings side by side - Altimeter with a live trend graph of the last four minutes and a session maximum - Speedometer in m/s, km/h, ft/s, mph or knots, with a rolling digit readout - HUD mode — rotate to landscape for a mirrored windscreen display. The screen stays awake while you drive. - G-force gauge with gravity excluded, measuring real acceleration and braking - Sunrise, sunset and length of day for your current location - Moon Status showing the current phase, time until the next full and new moon, distance from Earth and days into the lunar cycle - Flashlight for reading a map after dark Swipe left on Solar Times to reveal Moon Status. Solar and lunar calculations are performed directly on your device. KNOW HOW GOOD YOUR FIX IS Most apps show a position and leave you to assume it is accurate. Global Position displays the measured accuracy of your current fix in metres, colour-coded Good, Fair or Poor, so you know whether to trust it before you act. You can also choose how hard the GPS works: High for navigation, Medium for everyday use or Low when conserving battery matters more than maximum precision. LOCATION AND MAP - Share your position and address with any app in one tap - Automatic address lookup from your coordinates - Standard, satellite and hybrid maps - Follow your location, or follow both your location and heading AVAILABLE IN 24 LANGUAGES Arabic, Chinese (Simplified and Traditional), Czech, Dutch, English, French, German, Greek, Hebrew, Indonesian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Russian, Spanish, Swedish, Thai, Turkish, Ukrainian and Vietnamese. Grid references remain in standard notation in every language, ensuring that what appears on your screen still matches your paper map and everyone else’s radio call. BUILT FOR THE FIELD Global Position is made for hikers, sailors, pilots, surveyors, field researchers, search-and-rescue teams, off-road drivers and travellers—anyone for whom knowing exactly where they are is not optional. Download Global Position and always know your position.

A globe you can turn in any direction, including straight over the poles. Great circle routes cross the poles, so we built a globe that follows them there. Enter two airports and the shortest path between them is drawn on the Earth itself, with distance and bearing on every leg. A Globe With No Pole Clamp Most map apps clamp the view at the poles. North stays up, and the globe stops turning right where great circle routes go. Great Circle Map uses a quaternion arcball instead. Drag in any direction and the globe follows, straight over the North or South Pole. Drag along the outer edge and the view rolls, so any direction can face upward. Find Any Airport • Search the full OurAirports database by IATA code, ICAO code, or city name. • Enter two airports and the great circle between them is drawn with its distance. • Recent routes save automatically and recreate with one tap. Waypoints and Weather • Double-tap anywhere on the globe to drop a waypoint. Double-tap it again to delete it. • Add as many waypoints as you want. There is no limit. • Every waypoint shows current conditions, temperature, and wind direction and speed in knots, from Open-Meteo. Distance on Every Leg • Each leg carries a sliding distance label and its initial bearing. • A running total stays pinned at the top of the screen. • Units switch between kilometers, nautical miles, and statute miles. Choose Your Earth • NASA Blue Marble satellite imagery or Natural Earth relief. • Toggle borders, airports, labels, and the grid. • View the globe in perspective or orthographic projection. Share the Route • Create Map exports your route as a flat map projection image. • The map unrolls across the antimeridian, so polar routes render cleanly. Privacy There are no analytics and no tracking. Weather requests send only waypoint coordinates to Open-Meteo.
