What Improvements Did We Make for AeroPoint 2s?

The internal hardware stack for the second generation of AeroPoints has been completely redesigned to expand GPS and connectivity capabilities.

Dual-frequency GPS

AeroPoint 2s have been equipped with a dual-frequency GPS receiver (unlike AeroPoint 1s, which were single-frequency). This improves:

  • The time required for a GPS fix in challenging environments.
    • 10-minute minimum with the Corrections Network (from 45 minutes)
    • 2-minute minimum for PPK workflow corrections (from 10 minutes)
  • The number of constellations we can observe to gather data
    • Previously, we were only observing GPS and GLONASS.
    • Support for Galileo and Beidou has been added.
  • The quality of data collected, increasing accuracy
    • Dual-frequency GPS receiver limits multi-pathing errors during data collection for more reliable positional results.
    • Increased maximum baseline distance to 40km (from 35km) to expand AeroPoint correction network coverage by 50% from existing correction sources.
    • Maximum capture time increased to 12 hours (from 5 hours) to facilitate larger jobs, without the need to leap-frog your ground control.

Power Performance and Charges

To help customers who struggle to charge their AeroPoints through solar power due to location or weather, we’ve added a 12- 24V DC charging port. 


AeroPoints will fully charge using the port in three hours (compared to eight hours with the solar panel, at peak efficiency). Chargers are included with AeroPoints, and additional ones can be purchased separately.


With a board redesign, we've also increased the battery life to 100 hours of capture time (from 45 hours). 

Bluetooth and WiFi

We’ve made it easier to monitor your AeroPoints’ operations and power levels while deployed. Bluetooth capabilities connect your AeroPoints to a mobile app, where you can view:

  • Real-time diagnostic information
    • GPS capture size and elapsed time
    • Upload status and progress
    • Battery level and charging status
  • Wireless hotspot configuration for APs connected to the app


Second-generation AeroPoints also have upgraded WiFi, doubling data-upload speed limits to be more forgiving on higher latency/lower bandwidth networks.

I still can't do it!
