In the modern Internet of Things (IOT) world, customers are looking for “off-the-shelf” networked solutions to low volume, unusual and challenging GNSS applications. More often than not, impacted by tight schedules, no one wants to spend the either time or expense developing “non-core” unique GNSS solutions. It is exactly these market situations that SCORPion was developed to address.

Our small Scalable Continuous Operating Receiver + Processor Integration (SCORPion), electronic platform is a compact tightly integrated GNSS Receiver and Linux Processor + FPGA solution. It’s specifically designed, to deliver flexible, affordable, and uniquely tailored solutions. Drawing upon our extensive software library (25 years in development) associated with industry leading Novatel’s OEM product range, SCORPion with it’s the reliable internal “Thin Linux” / FPGA architecture, can rapidly be configured to meet limitless number of different mission configurations while maintaining very low implementation costs.

If the GNSS majors don’t produce exactly the solution you require, consider a customized SCORPion solution to exactly meet your requirements.

Technical Overview

On the surface the SCORPion technology might look relatively straight forward (GNSS Receiver integrated with a Linux Process), however, look a little deeper into the additional technologies associated with FPGA hosting of advanced signal process processing algorithms, and/or coupling with NovAtel’s OEM’s API capabilities for solution performance turbo charging. Scorpion delivers rapidly configurable real time numerical signal processing and analysis all from a single box.

SCORPion – GMMR GBAS Multi Mode Receiver (IGM)

The GMMR is a highly reliable, adaptable low cost monitoring solution, (Airborne and/or Ground), for continuous reception of aviation VHF GRAS/GBAS signal transmissions. The GMMR delivers an extensive variety of processed DGPS navigation messages and other statistical outputs, while retaining high adaptability for interfacing to internal bulk data storage and/or communication devices, and IOT networking. Employing an internal NovAtel OEMV Receiver loaded with specialised API firmware configured to directly control a Telerad RE-9009A D8PSK VHF Receiver while also differentially processing in real time the incoming ICAO DO-246C messages, (GBAS Type 1,2,4 and GRAS Type 101) for any defined D8PSK slot.

SCORPion – GVTE GBAS VHF Transmissions Emulator

The GVT Emulator is designed as a low cost test solution to assist in GBAS pre-installation engineering risk mitigation studies. Employing a precision NovAtel OEMV Receiver loaded with specialized internal API firmware, it directly controls a Telerad EM-9009A D8PSK VHF Transmitter (80 watts) and generates in real time either RTCA DO-246C GBAS Type 1,2 and 4 messages for any defined D8PSK slot.  The GVT Emulator delivers aviation users an efficient and easily deployable GBAS support tool for generating engineering GBAS VHF test transmissions, in advance of future deployed final DO-178B certified vendor equipment.

SCORPion – uLOG Small GNSS Data Logger

uLOG is a small GNSS data recorder designed to capture and process GNSS data in real time while providing advanced IOT connectivity if required. In some instances it’s used to capture very high speed USB bulk storage of data from IMU type devices, while in other instances, it’s used to distil / process large volumes in GNSS environmental data in real time while searching for unusual / significant circumstances. Irrespective of what the required mission, the uLOG technology has a long and successful history for remote unattended IOT installations.

SCORPion – DRFI Detect RFI Event Monitor

DRFI is specifically designed to monitor each of the three GNSS main frequency bands looking for in band interference, real time scanning the OEM7 Receiver generated PSD data and specifically logging the PSD data as each event is found. DRFI with its advanced IOT connectivity is specifically designed as a low cost easy to deploy companion to the more sophisticated GRIFFIN range of products. Initially, DRFI would be used to perform preliminary regional RFI characterisation (type, frequency, region etc..), before deploying a comprehensive GRIFFIN system to undertake final precise source GEO-Location activities.

SCORPion – GEMS GNSS Environmental Monitor for Signal & Atmosphere Data

The GEMS configuration is designed to provided real time monitoring of the GNSS Space weather conditions and then simultaneously update the nominated statistical models in real time. Modelling of the different satellite constellation Clocks and Ephemerides, plus, ionosphere and troposphere can all occur simultaneously on either the FPGA fabric or under ARM Linux OS. The FPGA fabric is perfect for dealing with the large numerically intensive algorithms quickly and effortlessly.


CORS is the ideal solution for simple low cost regional GNSS Reference Station implementations for agriculture communities and mining. With a configurable internal Linux based Processor integrated with either a NovAtel OEM6/7 internal Receiver, CORS delivers reliable precision GPS, GLONASS, GALILEO and BEIDOU measurements to a broad variety of communications gateways including, NTRIP over the internet, RS-232 for UHF modems, and USB for inter commuter and/or data storage options.
