The antenna facade area is top surface of the BTGPS, as indicated Figure 2 and 3. Keep this surface clean and clear view to the sky while operating GTGPS. Do not let this frontage surface area covered fully or partially by any object especially contains metal and/or electromagnetic wave absorption materials such as screwdriver, pen, watch, floppy diskette, CD and metal wires, thin metal foil like aluminum foil and metal-coated plastic bag, water or liquid, and carbon paper. While operation, sometimes even in non-operation state. Antennae Facade Area External Antenna Port (MCX type) Figure 3 Power Switch The Power Switch is indicated as "B" in Figure 2. Symbol: Power-off position of the Power Switch. 17 External Antenna Port Your BTGPS is equipped with a RF connector port (MCX type) for connecting with external active antenna(optional accessory) when operating under certain environment situation, such as inside a vehicle and where satellite signals are blocked or obstructed. Make sure using the external antenna(optional accessory) supplied by EMTAC. Use of other active antenna will severely degrade positioning performance or even damage the receiver. Please read basic guidelines before using the external active antenna accessory. LED Indicators In Figure 2, three LED lights indicate the operation status of Bluetooth(BLUE), GPS(GREEN) and Battery(YELLOW/RED) of the BTGPS. Symbol: Blue LED Light indicates Bluetooth pair/connect status Flashing every 1 second: BTGPS just power-on and waiting for pair/connection. Flashing every 2 seconds: BTGPS is connected and paired with the host. Symbol: Constant on: Flashing: Symbol: Green LED Light indicates GPS status When BTGPS just power on, attempting to fix a position. Battery fully charged Red light constant on: Yellow light constant on: No light (off): Power Jack When the Red LED light is constant on, you need to charge the Li-ion battery inside the BTGPS by plugging the charger's plug into the power jack which indicated as "E" in Figure 2. DO NOT USE OTHER CHARGER to charge the BTGPS. 18 External active antenna (optional) The external active antenna is an optional accessory. Just connecting the external active antenna to the external antenna port described in previous section "External Antenna Port". The active antenna is embedded magnet in the bottom for easy mounting on metal surface, be caution not put near to materials are sensitive to magnetic field, such as magnetic storage media like floppy diskette. Figure 4 is the reference photo of the optional external active antenna. Use of other active antenna will severely degrade positioning performance or even damage the receiver. Figure 4 19 3. Operation Guide Before using the BTGPS, first make sure to prepare following steps are ready for operation. The GPS application software is correctly installed in the host platform(s) The BTGPS is fully power charged Check the Bluetooth is ON in the host Identify the operation environment whether external antenna needed or not For information about the operation of the host and GPS application software installation procedures, please refer to the documentation that accompanies each product, respectively. In this Chapter, a step-by-step operation procedure is described. Step-1 To install the GPS/MAP application software Step-2 To pair/connect the BTGPS with the host Step-3 To operate the GPS/MAP application software Step-4 To connect with the external active antenna(optional) Indication of BTGPS operation To Charge the battery of the BTGPS 20 Step 1 To install the GPS/MAP application software Before operation the BTGPS, make sure the GPS/MAP application software is properly and completely installed in the host platform. To install the GPS/MAP application software, please consult and follow the operation guide described in the user guide of the GPS/MAP application software. In this User Guide CD-ROM, there is the "Crux_Viiew Test Program"(trial version) for testing purpose. Please follow the step-by-step operation guide indicated and described in the CRUX_VIEW(Trial) Manual file(in . pdf format). Note: (a) The Crux_View Test Program is a trial version program and only for testing purpose. (b) The Crux_View program is only for BTGPS used with PocketPC(PPC) PDA with Bluetooth enabled. [. . . ] Multipath Multipath is the reception of a signal both along a direct path and along one or more reflected paths. standards committee that defines data message structure, contents, and protocols to allow the GPS receiver to communicate with other pieces of electronic equipment aboard ships. Selective Availability (SA) Selective Availability is a process whereby the U. S. Department of Defense dithers the satellite clock and/or broadcasts erroneous orbital ephemeris data to create a pseudorange error to prevent adversaries from using the extremely accurate GPS positioning data.
