GNSSGPSGLONASS

The 3G+C is a high-precision antenna for all present and future GNSS signals and is thereby useable in all fields of surveying. The patented positioning of parasitic elements allows an excel- lent multipath reduction. As an ideal reference station antenna it is provided with a higher gain of 42 db. In this way cable lengths of 100 meters and more can be utilized. Low-elevation satel- lites are received with a greater signal-to-noise ratio as well. The reception of Omnistar correc- tion signals is additionally optimized. The new antenna is called 3G+C maritime . Model calibration was performed by the measure- ment chamber of the University of Bonn as well as the company Geo++ on a robot. The obtained data were deposed at the IGS Institute in Antex format so that the 3G+C antenna can be used on IGS stations as well. Here the information is accessible for interested parties at all times. As the results show, the single layer technology reaches an extreme low phase center variation in com- parison to other chokering reference station antennas. For mobile usage the antenna can be equipped with a damper; its special rubber compound does not influence the reception quality and provides effective protection against falls. With the 3G+C antenna very good results are achieved in monitoring and deformation analysis.
