GE864-GPS for positioning in security applications
Telit has introduced the GE864-GPS for highly integrated positioning solutions in automotive, tracking or security applications requiring 2G network connectivity in a very small footprint.
The GE864-GPS shares the identical form factor and is pin-to-pin compatible with Telit's GE864 range, making it the smallest GSM/GPRS module on the market with full 48-channels A-GPS functionality.
It combines the performance of Telit's GSM/GPRS core technology with the latest SIRFSTARIV high-sensitivity single-chip A-GPS receiver.
The assisted GPS receiver features an optimised power-management function, which allows it to maintain hot-start capability at minimal energy consumption, offering a position resolution accuracy of less than 2.5m.
The GE864-GPS supports Satellite Based Augmentation Systems, 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 such as 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 2.9mm) 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 significantly reduced as compared to conventional mounting technologies, Telit claims.
Additional features including jamming detection, integrated TCP/IP protocol stack and Easy Scan offer benefits to the application developer without adding cost.
All Telit modules support the Over-the-Air firmware update by Premium FOTA Management.
By embedding Redbend's Vcurrent agent, 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 GSM firmware and will be available in the future for the GPS firmware.
