GNSS for reference stations
Set up your own Continuously Operating Reference Station (CORS) network with these GNSS receivers. A network of base stations can be established in an area where for example no current CORS network is available. Mining and other geographically remote sites use these as they are within the same area for a relatively long period of time. Once set up they transmit CRM+, RTCM2, RTCM3 and other similar types of correction data via UHF or through NTRIP. Some also allow you to log raw RINEX2 and RINEX3 data.
Simple GPS guide
Antenna – An external GNSS antenna is required in order to receive satellite date. Recommended in order to minimise interferences and correction error’s are Choke ring antenna ‘s. This come in either a 2D or 3D chocke ring variation.
