An all-in-one model placing importance on mobility in RTK-GPS work. Simple equipment changes RTK-GPS work. TOPCON's unique GNSS technology is naturally incorporated. The GGD and GGDM types can receive signals from the GPS and GLONASS satellites. Stable signal reception under adverse condition and fast initialize time promise an enhanced efficiency of RTK-GPS.

All-in-one GNSS receiver
The GDM and GGDM types contain a receiver, antenna and batteries, as well as small-area radio for reception's are superb all-in-one receivers exceeding RTK-GPS. Just connect the controller to the simple configuration and complexity of cable connection is eliminated. Excellent mobility is assured.
Small area radio contained (GDM and GGDM types)
A wireless modem needed for RTK-GPS is contained. A small area radio with a longer communication distance compared with specified low power radio stations is incorporated. Only a report is needed. License is no longer needed.
