A campaign has been launched on Crowd supply for Unsurv, which is an offline privacy-friendly, small, lightweight PCB (43 mm x 32 mm) loaded with an ESP32, GNSS reciever and NFC capabilities. It functions by using a combination of OpenStreetMap data on the SD card, and a custom Android app, enabling you to gather GNSS data throughout the day, and easily analyzing it and using it later on.

Speaking about Unsurv, the company says:
You can use Unsurv for a variety of other location-tracking functions, and you can access your Unsurv data easily via your smartphone and the dynamic NFC Tag which is fitted into the case. The Unsurv features a tiny BMA400 accelerometer which helps save precious battery capacity by managing power-saving features. It can even be adapted as an input device with tap and double-tap recognition. It is easy to use, just add a single cell LiPo battery, or USB power bank for more demanding tasks, and start gathering data. Unsurv is very efficient because, at the end of the day, most common Global Navigation Satellite System (GNSS) projects appear onto Unsurv offline, inclusive of surveillance cameras you would otherwise not notice.
