SnapperGPS: a low-cost/power GNSS receiver for wildlife tracking #GPS

The SnapperGPS receiver is a small, low-cost, and low-power GNSS receiver for non-real-time wildlife tracking. It employs the snapshot GNSS technology, which offloads the computationally expensive data processing to the cloud.

Features:

  • Measures 32.0 mm x 27.3 mm,
  • Operates for more than a year on a tiny 40 mAh battery,
  • Has enough memory to provide almost 11,000 position fixes,
  • Captures fixes in user-defined time intervals or externally triggered,
  • Needs only 12 ms of signal reception for a fix,
  • Employs multiple satellite systems for high reliability (GPS, Galileo, and BeiDou),
  • Achieves a median real-world tracking accuracy of about 12 m (before smoothing),
  • Maintains a real-time clock to accurately timestamp the fixes,
  • Measures the temperature in addition, and
  • Is configured via USB in your browser without the need to install a driver or an app.

The SnapperGPS GitHub repo provides the hardware design files that can be used to replicate a SnapperGPS receiver. See SnapperGPS.info for project details.

SnapperGPS V1.0.0 is certified as open source hardware by the Open Source Hardware Association with UID UK000044.
