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.
