Inside our base station · select a numbered component
The base uses a dedicated GNSS receiver, a Raspberry Pi Compute Module and a 4G modem on our own carrier board. Plug-in modules make repairs and replacements straightforward.
One Ethernet cable carries power and data. The carrier board charges the battery and provides UPS backup during a power cut. Approximately 10–12 hours of battery runtime at around 20°C. Runtime varies with battery condition and power use.
Why we chose each part. Photos are representative; supplied versions may vary.
Runs the base station software and manages its connections.
Raspberry Pi gives us a compact computer with strong software support and a widely supported Linux platform. The plug-in format makes it straightforward to replace or service without changing the whole carrier board.
Module version and configuration are matched to your base station.
Made in the UK.

Receives satellite signals for RTK corrections. Pre-configured with the correct base files for your existing setup, so guidance lines and boundaries stay in place.
Septentrio specialises in high-precision GNSS. Its mosaic range tracks multiple satellite systems and frequencies, with technology to reduce radio interference and errors from reflected signals. These are useful strengths for a base that needs to produce consistent measurements throughout the working day. We chose Septentrio for its receiver technology and focus on reliable positioning in demanding conditions.
Replacement receivers are supplied with the correct base files to match your existing installation.

Connects the modules, charges the battery and provides UPS backup during a power cut.
Our board brings the computing, satellite receiver, modem and power supply together. Built-in charging and UPS control keep the base running from its battery when mains power is lost, while the plug-in modules can be replaced individually.
UPS backup needs a connected, charged battery. Approximately 10–12 hours of battery runtime at around 20°C. Runtime varies with battery condition and power use.
Manufacturing origin unconfirmed.
5-year warranty.
