Global Navigation Satellite Systems (GNSS) Receivers

Global Navigation Satellite System receivers make use of satellite constellations to deliver high precision global positioning and time synchronisation.

The GEF has receivers available for loan that make use of the US NAVSTAR (GPS) and Russian GLONASS GNSSs. Our latest receivers (Leica GS10) will also be able to receive the forthcoming Chinese COMPASS and European Galileo signals once operational.

Positioning capabilites

All of our receivers are geodetic quality, capable of measuring to sub-centimetre precision when used in differential mode. We have accessories such as radios to enable full Real-Time Kinematic (RTK) positioning to a within few centimetres over ranges of kilometers.

Equipment available for loan

We have 16 Leica VIVA GS10 receivers available for loan. For short loans of only a few receivers, you may be able to use our minor loans procedure and apply throughout the year. If you need larger quantities or a longer length of loan, you will need to use our standard application form and apply before the next deadline on 1st November 2024.

Typical Applications

Our receivers have been used in a wide variety of applications, are highly configurable and often support our other equipment types e.g. GPR or TLS. Recent uses have included:-

• Monitoring ice flows in Greenland and Antarctica - View a report by Prof Peter Nienow
• Surveying ground control points to support airborne or satellite data - View a report by Dr Duncan Quincey
• Detailed mapping of debris and watermarks after tsunamis and floods - View a report by Prof John McCloskey
• Measuring the strain rates of glaciers
• Mapping uplift around a volcano - View a report by Prof David Pyle
• Tracking the behaviour of foraging ants - View a report by Dr Barbara Webb
• Supporting our other instruments such as TLS or GPR - View a report by Prof James Brasington
