Preface Welcome to the Thales MobileMapper™ Beacon User Man- ual and thank you for buying this high-performance, belt- mounted DGPS system. This product is an accessory to the MobileMapper and MobileMapper CE handheld GPS/GIS data collection systems. The purpose of the MobileMapper Beacon system is to receive accuracy-enhancing corrections from Coast Guard beacon networks. Coast Guard differential GPS beacons have been installed throughout many locations in the world, and send GPS cor- rections to users in order to improve GPS accuracy and in- tegrity, using a medium frequency signal. This service facilitates the Coast Guard requirements to provide a safe navigation and position service to its users. Over the last many years, Coast Guard beacons have been used to great success by terrestrial users. In fact, a program is currently in place to provide dual redundant coverage of beacons throughout the continental United States for a variety of land-based uses. GPS corrections received by the MobileMapper Beacon are transmitted to the GPS data collection system using Blue- tooth® (1) wireless technology. (1) The Bluetooth® trademark and logos are owned by Bluetooth SIG, Inc. and any use of such marks by Thales is under license. Other trademarks and trade names are those of their respective owners. 1

The MobileMapper Beacon may also be used with 3rd-party GPS systems that accept RTCM SC-104 corrections via a Bluetooth or traditional hard-wired serial connection. The following figure shows the MobileMapper Beacon sys- tem. We have written this document to assist you with learning how to use the MobileMapper Beacon system, how it oper- ates with GPS equipment, and provide some general infor- mation on Coast Guard beacon technology. Key Features • Fully integrated Coast Guard beacon receiver and antenna • All-day battery life using either four alkaline, 1.5-V Lith- • ium or NiMH rechargeable AA-type batteries Integrated Bluetooth wireless technology for communi- cations with the MobileMapper CE • Convenient belt-mounted carrying system • User interface includes a power button and status lights • Conventional hard-wired serial port for communication with other GPS equipment via a cable with standard DB9 connector. 2

Introduction The Thales MobileMapper Beacon system is an accessory to the Thales MobileMapper CE GPS data collection system. The MobileMapper Beacon is a self-contained, Coast Guard beacon receiver system. It features an internal beacon re- ceiver and magnetic field beacon antenna, wireless commu- nications, and a compartment for 4 AA batteries. The following figure illustrates the use of the MobileMapper Beacon. Note - Though the MobileMapper Beacon is primarily intended for use with our MobileMapper and MobileMapper CE GPS/ GIS data collections sys- tems, it may be used with any GPS system that support RTCM-based real-time differential corrections. In order to connect to other devices, you will need to ensure the GPS supports either Bluetooth wireless tech- nology or an RS-232 serial port. Receiving Your Shipment If you find that any of the items are damaged due to ship- ment, please contact the freight carrier immediately for as- sistance. If you find that the system is incomplete for some reason, please contact your point of sale for assistance. MobileMapper Beacon System Each MobileMapper Beacon system is composed of: • MobileMapper Beacon Coast Guard beacon receiver unit • 4 AA Batteries • Belt-mounted carrying system • 1 battery clip for easy loading of batteries • Warranty card • User Manual • A PC-interface cable for serial communications. 3

Using the MobileMapper Beacon User Interface The MobileMapper Beacon user interface is located on the top of the unit. This interface consists of a power button and three lights. A red light next to the power button indicates the unit is on. A green light comes on once the unit has locked onto a DGPS transmitter with a signal-to-noise ratio greater than seven and is sending the corrections to the GPS receiv- er. A blue light next to the Bluetooth symbol is illuminated when the unit is sending the corrections to the GPS receiver via the Bluetooth connection. The following picture shows the status lights and power but- ton located on the top surface of the product. Please note the power button and indicator lights are visible through a cut- out located on the top of the pouch, supplied with the system. 4
