So, what exactly makes a GPS device good in this crowded market? Important features include a large readable display, a variety routing options, built-in maps, a large points of interest (POI) database, and most importantly, a strong receiver. The SiRF Star III GPS receiver has become the defacto standard for GPS devices because of its fast Time to First Fix (TTFF)- the time it takes the receiver to find its position in a new location- as well as its ability to acquire and maintain a signal even in dense urban environments. (Power consumption is said to be under 15 mW, in 1Hz (map updates every second) tracking mode and acquisition sensitivity is rated at -158 dBm in assisted GPS (A-GPS) and autonomous hot-start modes, and -160 dBm when tracking.) Pricing, an important consideration for most people. LGSF2000 seems to have the both advantages. LGSF2000 is a GPS receiver that is made in Taiwan, where most of the GPS devices are from.

The size of the container is 15.6cm(length)x13.8cm(width)x7.4cm(height).

After you open the box, you can see a GPS receiver sitting there. Its size is 41(W) x 72(L) x 22(H) mm, weight 80g with the battery.

The package contents GPS receiver, rechargeable lithium-on battery, Cigarette lighter adaptor, power adapter, USB cable and user guide.

For your battery to reach optimum performance, it is recommended to recharge the battery for 10-12 hours for the first time.

2.2.6 Interface?Communication with host platform via Bluetooth Serial Profile v2.0, auto-adjust transmission velocity NMEA 0183 2.2. ASCII output format (GPGGA, GPGLL, GPGSA, GPGSV, GPRMC, GPVTG).

Bluetooth GPS receiver is a compact design with internal passive antenna, with Bluetooth wireless technology and build in flash based firmware. Without any wiring requirement GPS receiver adds GPS positioning capability to any Bluetooth enabled device with lower power consumption. The high performance and high sensitivity to -159dBm may survey 20channels all-in-view tracking by the cold start. With the LED indicators, user may get the statues of power, Bluetooth and position surveying. Bluetooth GPS receiver supply an incredible high sensitivity for acquisition and superior navigation performance in urban, canyon and foliage environments. The applications include vehicle tracking, fleet management, chart, location-based Services security, marine navigation and agriculture.
