GPS Satellite Tracker+

View your GPS positioning data with a clean satellite sky visualization. GPS Satellite Tracker+ reads real location data from your iPhone and displays it alongside estimated satellite positions on an animated radar chart.

SATELLITE SKY RADAR
An animated polar chart shows estimated positions of GPS, GLONASS, and Galileo satellites overhead. Satellite positions are calculated based on orbital data, with the number and signal quality reflecting your current GPS accuracy.

ACCURACY GAUGE
A visual bar displays your current positioning accuracy in meters with clear quality labels — Excellent, Good, Fair, or Poor. See at a glance how reliable your location fix is right now.

COORDINATES & POSITION
View your latitude and longitude in decimal degrees, updated continuously from your iPhone's GPS receiver.

ALTITUDE & SPEED
Monitor your current altitude above sea level and ground speed in real time. Useful for outdoor activities and travel.

HDOP INDICATOR
Horizontal Dilution of Precision gives you a sense of positioning quality. The value is derived from your current accuracy conditions.

CONSTELLATION BREAKDOWN
See how many satellites from each constellation (GPS, GLONASS, Galileo) are estimated to be in view, with color-coded dots on the radar chart.

Note: Satellite positions and signal values shown in this app are estimates based on orbital calculations and your device's GPS accuracy. iOS does not provide direct access to individual satellite data.
