Contact us for pricing on ComNav GNSS receivers, antennas and OEM boards.

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, harbour construction, land surveying, marine surveying and in any project where accuracy and reliability matter the most.

  • 256 channels and unmatched GPS / BeiDou / GLONASS multi-constellation tracking performance while already designed to track GALILEO
  • Compact housing with a variety of interfaces for different external devices access
  • Powerful remote control capacity for access, configuration, programming,data download, reboot/restart, firmware update, code registration and much more.
  • Large capacity internal memory and expendable memory card for long term big data storage
  • Integrated battery serves as either the primary power source or the stand-by Uninterrupted Power Supply (UPS) backup

Powerful built-in web user interfaces provide full information such as receiver status, configuration, firmware update and data access control
