The SnapperGPS receiver, developed in the Department of Computer Science at the University of Oxford, is a small, low-cost, 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. Beyond that, the SnapperGPS is special in that it:

This version of the SnapperGPS uses a pair of LR48 or SR48 button cell batteries, sold separately. These are a common button cell alkaline battery and should easy to find locally or online.
On the SnapperGPS-Housings Github are some creative ideas about DIY enclosures, so that your receiver will perform in whichever environment you choose to deploy it. These options include 3D printed cases, heat-shrink tubing, vacuum packing, and a specially designed commercial box.
Some of these designs were intended to fit the older versions of the SnapperGPS, so modifications may need to be made to fit the V2.2.0. Please see the changes from previous versions.
Jonas Beuchert is funded by the EPSRC Centre for Doctoral Training in Autonomous Intelligent Machines and Systems (DFT00350-DF03.01) and develops SnapperGPS as part of his doctoral studies. The implementation of SnapperGPS was co-funded by EPSRC IAA Technology Funds (D4D00010-BL14 and D4D00190-BL03.01).
