2. Introduction
The BC-337 is a GPS receiver with Compact Flash type Iinterface and it has a built-in high sensitivity
antenna for tracking signal. Based on the SiRF star III high performance GPS Chip Set with very high
sensitivity (Tracking Sensitivity: -159 dBm), it has an extremely fast TTFF (Time To First Fix) capability
at the low signal level. The BC-337 is well suited to system integration and users who use PDA or
notebook PC. It satisfies a wide variety of applications, including car navigation, personal navigation of
touring devices, tracking and marine navigation purpose. Users can simply plug it into a PDA or other
type of handheld PC running with suitable mapping and routing software for navigation.

2.3. External Antenna
Basically, you don’t need external antenna to perform GPS positioning with BC-337; it already has a
built-in antenna. The only condition that you need external antenna is when BC-337 unit can not “see”
the sky, For instance, when you are in a car, or any environment that GPS signal is blocked, the
external GPS antenna will help to receive better GPS signal.
Plug the external antenna with MMCX connector to the plug on BC-337. Place the magnetic external
antenna on the roof of the car or the outdoor open-space, and make sure not to put it upside down.
That is, the magnetic side is the bottom side, and the upper side must face to the sky in order to
receive better signal.
Note: Hold the antenna connector while you plug the external antenna into the BC-337 or unplug
the external antenna from the BC-337. Do not pull it by the cable line.
