A ready to install device

The M300 is designed as a multi-purpose sensor for a range of applications. With its powerful integration ability, the M300 serves as a key part of a geodetic reference station, deformation monitoring system, machine guidance, harbor construction, land surveying, marine surveying or other high accuracy system.

Modular Design

Modular design makes M300 easily to integrate much more sensors for range of applications, such as radio/GPRS for RTK datalink, LAN port for internet connection.

GPS + BeiDou + GLONASS three constellation Technology

With its advanced dynamic acquisition ability and high accuracy carrier phase algorithms, the three constellation system high dynamic processing engine enhances the reliability and consistency of work in difficult and challenging environments such as land slide monitoring projects.

All in one device with correction signal reception

OEM card and UHF are integrated in a single enclosure. The M300 makes it easily to configure the output of data as required. Optional installation makes the M300 for multiple applications, for example the PPS output option makes it easy to use the M300 with 3D scanners.
