CMT's Coast Guard Beacon Receiver System

The GPS-BEAC-PKG allows your CMT GPS/GIS rover to receive real-time differential corrections from Coast Guard beacons broadcasting this data.  With the reception of the real-time signal, your CMT GPS/GIS rover can achieve the following RMS accuracies:











March II-E????? 1-5 m

MC-GPS?????? 1-3 m

ALTO-G12????? 60-150 cm

HP-GPS-L4???? 30-100 cm

Simple User Interface
The GPS-BEAC-PKG is easy to setup and use. It can be quickly attached to your GPS/GIS Field Computer for a simple real-time solution. CMT GPS/GIS rovers provide several useful real-time options.  For example, you may configure the GPS/GIS Field Computer to log raw GPS data in the event that the real-time signal is interrupted. This practical option allows you to continue your data collection session and perform post-processing differential. Also, output corrected NMEA data for accurate real-time navigation in PC-GPS.

Easy Setup 
Plug the Beacon Receiver into the battery and it automatically begins searching for a signal.  If one is available, it will lock onto it in a few minutes.  The beacon receiver has two LEDs on it. The red POWER LED lights up when you turn it on.  The green LOCK LED lights up when you are receiving a beacon signal.

Plug the male DB-9 connector from the beacon receiver into COM2:(this the female) of your CMT GPS/GIS rover.   On the CMT GPS/GIS rover, go to the Setup RS-232 Input/Output screen.  You'll see that COM2: is set to RTCM-104 INPUT.  Make sure the baud rate is set to 4800. Once it is connected to your CMT GPS/GIS rover, with GPS receiver on, watch for the tracking status indicator to turn to N3Cx.
