Top quality measurements for Great Britain’s national CORS network

great_britain_RTK_network

Ordnance Survey (OS), Great Britain’s national mapping agency, is widely recognized as one of the world’s most advanced and reliable sources of geospatial data and cartographic products. OS operates OS Net, a national RTK network of more than 115 GNSS base stations. PolaRx5 multi-frequency GNSS receivers are installed in this GNSS CORS network (Continuously Operating Reference Stations), providing high-accuracy services to surveyors, engineers as well as many other users in industries such as construction and precision agriculture.  

GNSS receivers are vulnerable to radio interference, which can degrade the quality of GNSS satellite measurements. To counter this and to provide robust and highly reliable positioning data, Septentrio’s PolaRx5 receivers include a spectrum analyzer and AIM+ anti-jamming and anti-spoofing technology.

 

The unique interference mitigation technology of PolaRx5 helps us in our constant aim in improving our positioning services to the public.

  • Full control to enable or to disable data processing options such as smoothing or multipath mitigation
  • Quick and easy installation as well as monitoring via the graphical web interface
  • Quality indicators can be viewed remotely for efficient station health monitoring

Respected around the world, Ordnance Survey exists over 220 years. New uses for its data have emerged and the market has grown significantly, with government and businesses using OS products to save millions of pounds. Their goal is to make data more accessible, ranging from strategy formulation and geospatial data capture, to product development and marketing.
