Leica announces latest GNSS technology

(Heerbrugg, Switzerland, 22 December 2008): A four constellation GNSS will soon become reality, and will deliver a new dimension in GNSS performance and efficiency. Leica Geosystems’ concept means that all existing Leica GPS1200 systems can be upgraded to the very latest technology.

The announced Leica GPS1200+ supports the new GPS L5 signal, GLONASS L1 and L2, and will also be able to track Galileo and Compass satellites when available. The flexible design of Leica GPS1200+ is claimed to be 100% future proof and is already now compatible with the four global navigation satellite systems.

GPS L5 is the new third GPS frequency which will allow increased redundancy, faster signal acquisition, and improved multipath performance – ultimately resulting in longer RTK ranges and faster ambiguity resolution. Galileo will add another 30 satellites to the GPS and GLONASS constellation providing additional benefits. With an average of 20 satellites in view 24/7, the speed and accuracy of GNSS will be further improved.

Leica Geosystems is the first to offer full support of the most modern and accurate Galileo AltBOC signal, which will significantly improve the differential code accuracy for periods when ambiguities could not be solved. The full operational capability (FOC) of Galileo is planned for 2013, with the first operational satellites being available from 2010 onwards. The Compass signal definition is not fully finalized, although Leica GPS1200+ supports Compass as known today.

Leica GPS1200+ includes the proven SmartTrack+ and SmartCheck+ technology. The instrument includes the third generation of SmartTrack+ measurement engines with 120 channels and offers enhanced signal processing and industry leading measurement quality. SmartCheck+ guarantees maximum reliability by continuously checking results. Combined with the benefits of being built to tough, military specifications and complete flexibility of deployment with other Leica System 1200 instruments, Leica GPS1200+ is not only the best system today, but also well into the future, a real plus.
