Example of a station setup using a Raspberry Pi 3+, Mosaic X5, and a temperature and pressure logger.

Our system is built around high-quality sensors, with data logging and real-time access managed by a Raspberry Pi 3+. We deliberately use the older Raspberry Pi 3+ model due to its lower power consumption, which we also monitor as part of the setup. Real-time data is available for most sites via local Wi-Fi or a SIM connection.

The GNSS component is the Septentrio Mosaic X5, a compact multi-constellation receiver module, typically paired with a Harxon GPS 1000 survey antenna. Meteorological data are collected using a Bosch BMP388 (barometric pressure and altitude) and an ASAIR temperature sensor, with data processing handled by an Adafruit Feather.

All software was developed at the University of Potsdam.

We house the hardware in multiple enclosures to ensure safe operation, and include a 12V backup battery to maintain functionality during power outages.
