TGM100-PRO Advanced RTK GPS/Compass Module

The TGM100-PRO Advanced RTK GPS/Compass system provides precision position and heading information for ground-based, mobile or airborne applications. Leveraging the latest technology from uBlox™, Taoglas™, Honeywell™ and Microchip™ the TGM100 system is designed to enable RTK Fixed Mode under normal operating conditions. An innovative LED feature provides an instant graphical representation of the GPS receiver’s performance, including received satellite constellation and signal strength, RTK mode etc. The TGM100-PRO features a 32-bit PIC32MX microprocessor with RS-562, CAN and Ethernet interface (CAN and Ethernet interfaces are optional).
