The Leica GMX901plus is an affordable and rugged GNSS receiver that delivers precise and reliable data about movements of sensitive structures such as mine walls, rock slopes, dams, and buildings. For time-critical applications that require high rate data and a higher accuracy the GMX901plus can be smoothly upgraded to a powerful L1/L2 GPS/GLONASS receiver with an update rate of 5 Hz.

Designed with a focus on the essential with low power consumption, high quality measurement, simplicity, and durability, the Leica GMX901plus is an ideal sensor for monitoring structural movements. It has a robust housing that is water, heat, cold and vibration resistant that can be easily mounted on the infrastructure for long term monitoring.

Smooth upgrade for time-critical observations requiring high-rate data. The basic GMX901plus is a L1 GPS receiver for cost sensitive projects. For monitoring projects that require a higher accuracy and high-rate data, e.g. earthquakes, bridges, high-rise buildings, the GMX901plus can be smoothly upgraded to a powerful L1/L2 GPS/GLONASS receiver with an update rate of 5 Hz. With this upgrade users take advantage of high accurate data and positions for a detailed deformation analysis to take the right decision when movements become critical.

Seamlessly integrated for data processing with Leica GNSS Spider and Leica GeoMoS.

The Leica GMX901plus connects seamlessly to the Leica GNSS Spider advanced GNSS processing software for coordinate calculation and raw data storage. The Leica GeoMoS monitoring software can be used to provide integration with other sensors, analysis of movements and calculation of limit checks. Third party analysis software can also be easily integrated via the standard NMEA interface of Leica GNSS Spider (RINEX).

Leica Geosystems’ Monitoring solutions combine geodetic, geotechnical, and meteorological sensors for reliable, precise data acquisition and secure data transmission with advanced processing, sophisticated analysis, and visual representation.

Using standard interfaces, open architectures and scalable platforms, the solutions are customizable to meet individual requirements – for permanent or temporary installations, for single sites or monitoring networks. Modern technology makes installation easy and allows for reliable and state-of-the-art communication via mobile networks.
