C3 Display Controller vs GPS Status & Satellite Sky

C3 Display Controller helps you quickly set up and manage compatible C3 display devices from your phone. Key features: Scan and connect to nearby supported devices using Bluetooth Low Energy (BLE) Send Wi-Fi SSID and password to the device for network setup View real-time device status, including Wi-Fi connection state, SSID, IP address, battery level, and charging status Enable or disable slideshow mode Select and update slideshow images from available slots Set slideshow timing and send control commands directly to the device C3 Display Controller is designed for fast onboarding and day-to-day device control in a simple, focused interface.

Read your exact position in every format at once — decimal degrees, DMS, DDM, UTM and MGRS — and copy any of them with one tap. YOUR POSITION, EVERY FORMAT • Five coordinate formats shown together on the first screen • Tap a row to copy that exact string for a map, a message or a form • Horizontal accuracy and vertical accuracy, shown separately • Altitude above sea level, ground speed and course over ground • Metric, imperial (feet, mph) or nautical (feet, knots, nautical miles) When the phone has no valid altitude or you are standing still, the app shows a dash instead of a made-up 0 m or 0°. SAVE AND FIND PLACES • Save here: store the current fix under a name you choose • Average here: collect up to 30 fixes over 30 seconds and save the mean, with an estimated uncertainty that never claims to be better than the fixes it came from • Rename or delete saved places at any time • Go to a saved place: distance, bearing and ETA, with an Arrived badge within 100 m. The arrow follows your GPS direction of travel, so it works while you are moving — it is not a magnetic compass • Export all saved places as CSV or GPX PREDICTED SATELLITE SKY A polar sky chart shows where the GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC and SBAS satellites are above you right now, calculated with the standard SGP4 model from public orbital data (CelesTrak) for your position and time. The data refreshes weekly, a bundled copy works offline, and the date of the orbital data is shown under the chart. This is a prediction and the app labels it that way. iOS does not give apps per-satellite data, so the chart does not show which satellites your iPhone is receiving or using. A satellite list sorts everything by elevation. LOCK SCREEN While the app is open, a Live Activity shows accuracy, altitude, speed and course on the Lock Screen and in the Dynamic Island. The app does not track location in the background, so the card marks itself PAUSED instead of leaving an old reading looking current. GOOD FOR Hikers and paddlers checking a fix before relying on it · search and rescue, scouts and land navigation with MGRS or UTM · geocaching · drone and paragliding pilots · anyone who needs to send an exact position Readings come from your phone's own location services. Accuracy depends on the device and on a clear view of the sky. Available in 30 languages.
