Advantech ’s TREK products use assisted GPS (A-GPS), dead reckoning, Bluetooth and WWAN protocols (GPRS / GSM or CDMA / HSDPA), which can ensure that the equipment works normally in high-rise buildings, mountain areas, canyons, tunnels and underground parking areas. Improve fleet management efficiency and competitiveness. TREK series products adopt wide temperature working range, anti-vibration and shock design. The GPS function must have three elements: a GPS terminal, a transmission network, and a monitoring platform. These three elements are indispensable. Through these three elements, you can provide vehicle anti-theft, anti-robbery, driving route monitoring and call command functions.

About GPS
GPS is the abbreviation of English Global PosiTIoning System (Global Positioning System), and its Chinese abbreviation is "ball position system". GPS is a new generation of space satellite navigation and positioning system jointly developed by the US Army, Navy and Air Force in the 1970s. Its main purpose is Providing real-time, all-weather and global navigation services for the three major areas of land, sea, and air, as well as for military purposes such as intelligence collection, nuclear explosion monitoring, and emergency communications, is an important component of the US's global strategy. After more than 20 years of research and experiments, which cost US $ 30 billion, by March 1994, 24 GPS satellite constellations with a global coverage of 98% had been deployed.
One factor that affects fleet management is the accuracy of positioning data. The accuracy largely depends on the positioning technology used. Advantech cooperates with leading chip manufacturers in the field of A-GPS and dead reckoning to develop a unique low-power technology that can provide advanced and reliable GPS solutions. These solutions can provide the fleet with the best sensitivity, connectivity, immunity and continuous tracking performance in the satellite signal destruction area.
AGPS technology
A-GPS technology is a technology that combines network base station information and GPS information to locate a mobile station, and can be used in GSM / GPRS, WCDMA, CDMA2000, and TD-SCDMA networks. This technology needs to add a GPS receiver module in the mobile phone, and transform the antenna of the mobile phone. At the same time, it needs to add a location server, a differential GPS reference station and other equipment on the mobile network. If you want to improve the positioning effectiveness of the program in indoor areas such as GPS signal shielding, the program also proposes the need to add a bit measurement unit (LMU) similar to the EOTD program.
Dead reckoning technology
About wireless transmission technology
As customer demands continue to increase, fleet management applications require a wider range of services, such as broadband 3.5 G access. Advantech's TREK series products use a module from the world's leading 3.5G embedded solutions in Sialer Wireless Communications, which is used to transmit and receive data packets through GPRS, CDMA and HSDPA. The module has passed FCC Part 22 H + Part 24E certification, which can fully guarantee the reliability and sensitivity of the system.
