With a configurable internal Linux based computer integrated with a NovAtel OEM6 Receiver, SCORPion delivers reliable precision GNSS 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.
All satellite navigation technology is based on tracking signals emanating from satellites orbiting at a distance of approximately 20,000 kilometers. With such a large distance, the signals that are being transmitted are received at extremely weak signal levels. While the receivers are designed to operate at these levels and produce reliable centimetre-level performance the fact that the signals are extremely weak makes them susceptible to localised environmental effects.
A standout threat is RF interference and the likelihood of experiencing intentional and/or unintentional RF interference is ever-growing. Any mission-critical system deployed with an intention of achieving high levels of accuracy and availability should have dedicated time and effort towards detecting and locating sources of RF interference.
During periods of RF spectrum profiling the raw data is analysed and checked for any instances and/or anomalies where the RF spectrum in the GNSS navigation bands. Short-range RF interference can be generated by electric motors, current switching in cables, high speed electronic processors, power supplies and/or a multitude of communications equipment. Furthermore, the effects may not be common across an entire site.
A thorough analysis and careful assessment of the RF environment underpins the ability to use satellite navigation for accurate and reliable operation of the spatial processing and navigation system.
