M300 Pro GNSS Receiver

The M300 Pro is designed as a multi-purpose GNSS receiver for a wide range of applications. With its powerful integration ability, the M300 Pro serves as a key part of positioning infrastructure, active geodetic network, deformation monitoring system, machine guidance, harbor construction, land surveying, marine surveying and in any project where accuracy and reliability matter the most.

Features

  • GPS:L1/L2/ L5, BeiDou B1/B2/B3, GLONASS:L1/L2, Galileo, QZSS
  • Compact housing with flexible interfaces for external devices
  • User-friendly front panel display and configuration
  • Full remote control with powerful built-in webserver
  • Large capacity internal memory and expendable memory
  • Integrated battery serves as a primary power or an UPS

All GNSS constellations on track

The M300 Pro is able to track all existing and future GNSS constellations including GPS, GLONASS, BEIDOU, Galileo and QZSS. There is no doubt that the M300 Pro is always keeping pace with GNSS development, which provides a robust and future-proof GNSS solution for CORS.

Proven design

The M300 Pro is designed as a multi-purpose GNSS receiver for a wide range of high-accuracy positioning applications. The user-friendly front panel makes it easier to configure and check receiver’s status. Customers also benefit from its flexible interfaces that support Ethernet, serial and USB connections, allowing users to combine with external sensors to meet the unique application demand.

Ideal for reference station

The integrated lithium-ion battery works as a primary power or an Uninterrupted Power Supply (UPS) backup, combined with raw data loop recording function, M300 Pro can achieve continuous long-term recording. These proven designs make M300 Pro an optimal choice for the reference station, deformation monitoring, harbor construction and any applications where positioning accuracy and reliability matter the most.

Powerful remote control

The powerful built-in WebServer provides a full remote control of receiver configuration, status checking, firmware update, data download and user management. The M300 Pro supports five independent data transfer through TCP protocol in RTCM, ComNav binary, NMEA, and BINEX data formats, combined with Email Alert and FTP push, which truly improves the effectivity and profitability of your business.
