A four-constellation Global Navigation Satellite Systems will soon become reality, delivering a new dimension in GNSS performance and efficiency. Leica Geosystem's future-proof concept ensures that all existing Leica GPS1200 systems can be upgraded to the latest technology available. In addition, it provides unprecedented upgradability, allowing users to add new capabilities to their application platforms based on their business needs. The Leica GSP 1200+ supports GPS L5 signal, GLONASS L1 and L2, and will also be able to track Galileo and Compass satellites when available.
