The New Leica Viva GNSS Receiver

P. Fairhurst, U. Glueckert, B. Richter

Abstract:	The new Leica Viva GNSS receiver series consists of 4 different GNSS receivers suited for a wide range of applications in the field of high precision GNSS. The main focus of this paper is on the Leica Viva GS15, but much of the described functionality is common to the entire Leica Viva GNSS receiver series including the brand new Leica Viva GS08 and Leica Viva GS12 and the well known Leica Viva GS10. Fig. 1 shows a cutaway image of the Leica Viva GS15. This is the only worldwide all-in-one, fully flexible professional GNSS receiver to support all future GNSS signals. The Leica Viva GS15 contains unique and innovative features, including the new Leica Geosystems Intenna technology (a patent application has been filed), making it the most functional and flexible professional GNSS receiver on the market. The new Intenna concept integrates the UHF, GSM, UMTS & HSDPA (3.5G), CDMA and GPS antennas inside a single GNSS housing. The Leica Viva GS15 is the only on the pole GNSS receiver to fully support a complete range of communication devices including CDMA, 3.5G, GSM, GPRS, Japanese CDMA, UHF and spread spectrum radios. Combining this with the Leica Geosystems Intenna technology makes changing communication devices seamless and fully flexible. The third generation of Leica Geosystems SmartTrack+ measurement engine can track all existing GNSS satellite signals and all those currently planned for the future. The Leica Viva GNSS receiver series include the Leica Geosystems SmartTrack+ measurement engine and all GNSS tracking features. SmartTrack+ includes the GPS L5, Galileo, GAGAN, WAAS, EGNOS, MSAS signals and is compliant with the planned Compass signals. Currently the Leica Viva GNSS receiver series are the only civil GNSS receivers that offer Galileo Alt-BOC tracking which includes unique signal modulation and low multipath. The paper describes the unique advantages of SmartTrack+ and moreover presents first results of the expected quality of the Galileo and L5 signals by analysing the existing signals. Beside superior tracking performance, reliable RTK algorithms are the key to an accurate position. The Leica Geosystems SmartCheck+ algorithm is continuously monitoring the data integrity to provide the highest possible reliability. This unique and proven
