GV55-Cost effective mini telematics devices for vehicle security and light duty applications
The GV55 Series includes models GV55 and GV55W, designed for vehicle security and light-duty applications. Both models have dimensions of 63mm x 50mm x 21.8mm and weigh 50g. They operate on a voltage range of 8V to 32V DC and have an operating temperature range of -30℃ to +80℃, with storage temperatures from -40℃ to +80℃.
The devices support quad-band frequencies (850/900/1800/1900 MHz) and are compliant with GSM phase 2/2+. They feature GPRS multi-slot class 12 and mobile station class B.
The GV55W model supports UMTS frequencies (850/1900/2100 MHz) with HSDPA R5 providing a maximum download speed of 3.6 Mbps and WCDMA R99 offering up to 384 kbps for both download and upload.
The devices include digital inputs for ignition detection and normal use, digital outputs with a maximum drive current of 150 mA, internal cellular and GPS antennas, and LED indicators for GSM, GPS, and power. A mini USB interface is available for upgrading and debugging.
The devices use a u-blox All-in-One GPS receiver with high sensitivity and position accuracy of less than 2.5m. The time to first fix (TTFF) averages 27 seconds for cold and warm starts, and 1 second for hot starts.
The devices support TCP, UDP, and SMS transmit protocols. They offer features like alarm status reporting, scheduled reporting, geo-fence alarms, tow alarms, speed alarms, driving behavior monitoring, crash detection, special alarms, remote control, and jamming detection.
The devices are equipped with a Li-Polymer backup battery (250 mAh) providing standby times of up to 59 hours without reporting. Reporting intervals affect standby time, with 5-minute reporting reducing it to 35 hours and 10-minute reporting to 45 hours for the GV55 model.
