🌍 #ArcGISEarth230Tips | Tip 45: Dive into Satellite & Location Details with NMEA Logs 🛰️📍

Did you know that ArcGIS Earth not only replays NMEA GPS tracks—but also lets you explore detailed positioning and satellite data at every moment?

📍 Go Beyond the Map with Location Information When working with an imported NMEA log, click the Location Information button to open two insightful tabs:

🧭 Location Details

Access key metrics about the device’s current position:

  • Latitude, Longitude, Altitude
  • Accuracy level and Fix type
  • HDOP (Horizontal Dilution of Precision)
  • VDOP (Vertical Dilution of Precision)
  • PDOP (Positional Dilution of Precision)

These details help you assess GPS signal quality and positioning precision throughout the track.

🛰 Satellite Information

Visualize the satellite environment in real time:

  • View the relative position of each satellite in the sky
  • Signal strength is displayed with dynamic bars—longer and darker = stronger signal
  • A compass-style map shows satellites orbiting around the device at the center

✨ This view updates continuously, giving you a real-time window into satellite coverage and positioning accuracy.
