The GE864-GPS shares the identical form factor and is pin-to-pin compatible with Telit's successful GE864 family, making it the smallest GSM/GPRS module in the market with full 48-channels A-GPS functionality, the company says. It combines the performance of Telit's GSM/GPRS core technology with the SiRFstarIV high sensitivity single-chip A-GPS receiver.
The assisted GPS receiver features an optimized power management function, which allows maintaining hot start capability at minimal energy consumption, offering a position resolution accuracy of less than 2.5m. Moreover, the GE864-GPS supports Satellite Based Augmentation System such as WAAS, EGNOS, MSAS and GAGAN. With a dedicated power supply circuit, the GPS chipset can work independently from the GSM chipset and still operates when the cellular part is in power saving mode or switched off. This function is helpful for battery operated solutions that activate the communication function only upon triggering events like e.g. location changes.
The GPS receiver is equipped with a flash-based memory, so the firmware can be upgraded. The ultra small Ball-Grid-Array package (size: 30 x 30 x 2.9 mm) allows the end application to have a very low profile and small overall dimensions, facilitating the design of extremely compact location based services solutions. Since connectors are eliminated, the cost is reduced as compared to conventional mounting technologies. These features, combined with the embedded Python script interpreter result in a very cost effective and well equipped platform, capable of becoming an integrated solution for the complete customer application, the vendor advertizes. Additional features including jamming detection, integrated TCP/IP protocol stack, and Easy Scan offer valuable benefits to the application developer without adding cost.
All Telit modules support Over-the-Air firmware update. By embedding RedBend's vCurrent agent, a proven and battle-tested technology powering hundreds of millions of cellular handsets worldwide, Telit is able to update its products by transmitting only a delta file, which represents the difference between one firmware version and another. FOTA service is available for the
