The new GM862-GPS module is at the cutting edge of the Telit product line. It combines superior performance in quad-band GSM/GPRS modem functionality with the latest 20-channel high sensitivity SiRFstarIII™ single-chip GPS receiver. Pin-to-pin compatibility to the previous GM862-GPS module enhances and extends the functionality of new and existing GPS applications.
With its ruggedized design, extended temperature range, integrated SIM card holder, and industrial-grade connectors, the Telit GM862-GPS is the ideal platform for mobile applications in areas such as telematics, fleet management, tracking, security, and vehicle navigation. The new GPS receiver features low power consumption with position resolution accuracy of less than 2.5m, SBAS (WAAS and EGNOS) as well as high sensitivity for indoor fixes.
These features combined with the available Python™ application development environment translate into a very cost effective and feature rich platform quite capable of becoming the total solution for the complete customer application. Additional features including jamming detection, integrated TCP/IP protocol stack, and Easy Scan® offer unmatched benefits to the application developer without adding cost.
