MG-31PG is based on the SiRF star II e-LP chip set, it is a new 12-channel "All-in-view" receiver module. It offers not only superior performance (integrated powerful ARM7 CPU core) but also high reliability at very competitive price in the market.

WAAS & EGNOS capability allows for accuracy to within 3 meters.
The miniature size (30.6x26x9.8mm) and flexibility for eight GPIO pins extension makes MG-31PG GPS module suitable for all embedded applications such as handheld, wireless, leisure, navigation, emergency call, and location identification. Additionally, its unique full shield design will efficiently withstand external EMI or RFI interference signals.

Main Features:
* SiRF Star II/LP (low power) chipset with embedded ARM7TDMI CPU available for customized applications in firmware
* 12 parallel satellite-tracking channels for fast acquisition and reacquisition
* Compact size( only 30.6*26*9.8mm, include RF shield and connector)
* High speed signal acquisition using 1920 time/frequency search channels
* Built-in WAAS/EGNOS Demodulator
* Low power consumption with Advanced Trickle-Power and Push-To-Fix mode
* Optional Rechargeable battery for memory and RTC backup and for fast Time to First Fix (TTFF)
* Support NMEA-0183 v2.2 data protocol and SiRF binary code
* Enhanced algorithms -SnapLock and SnapStart provide superior navigation performance in urban canyon and foliage environments
* For Car Navigation - Marine Navigation - Fleet Management - AVL and Location-Based Services Auto Pilot - Personal Navigation or touring devices - Tracking devices/systems and Mapping devices application.
