Telit Communications, a provider of M2M modules and solutions, has launched a new generation of GSM/GPRS/GPS modules. The key element of the new GE863-GPS and GM862-GPS modules is a high-sensivity SiRFstarIII 20-Channel Singlechip GPS receiver.
It was developed by SiRF Technology, a leading supplier of GPS-semiconductor - and software platforms for location technology.
The combination of GSM/GPRS-technology with GPS functionality in a single module significantly reduces integration efforts and costs, making the modules very attractive for cost-sensitive applications.
In recent years, GPS location technology emerged as a trend. In-car navigation systems and various plug-and-play solutions are offered to end users. A substantial market has developed for industrial- and consumer-oriented solutions, which record the position of people, devices or other mobiles using GPS. Moreover, GSM/GPRS/GPS technology is employed at highway toll systems.
As one of the first providers, Telit offers modules that combine GSM/GPRS and GPS technology with an ultra-compact size. Using the Telit solution, applications that so far needed to access several modules are now able to utilise all functionalities with one module.
Modules for various requirements
The range of Telit modules is tailored to different solutions and application areas. For solutions with small lot sizes that especially focus on achieving low integration costs, Telit offers the modem version GM862-GPS. This contains industrial connectors as well as a SIM-card reader that can easily be integrated.
For high-volume applications, which focus on a compact size and cost-efficient assembly concept rather than on integration costs, Telit offers the embedded module GE863-GPS with the innovative BGA assembly concept. It enables a direct connection between the module and the PCB of the end device. The absence of connectors and cables results in additional cost savings. Furthermore, a fast installation using pick-and-place processes as with standard SMD components, is possible. As both modules are quad-band compatible they can be used in M2M solutions worldwide.
The integrated SiRFstarIII 20-channel GPS receiver combines a complete A-GPS digital baseband processor with a RF front end in a single chip. It features short TTFF (time to first fix) and is able to track more than 20 satellites at once, achieving a TTFF of only one second in outdoor GSM environments. As it acquires signals down to -159 dBM, realtime navigation is also possible in challenging environments such as urban canyons and dense foliage.
