Sun Lili.Teng 7 SIMCom This document describes the hardware interface of the simcom module sim33ela which can be used as a stand alone or A-GPS(Assisted Global Positioning Systcm rcccivcr. As a wide range of applications can bc intcgrated SIM33ELA, all functional components of SIM33ELA are described in great detail SIM33ELA is a stand-alone or A-gPs receiver With built-in Antenna sim33ELa dont need an external Antenna. SIM33ELA can track as low as -165dBm signal even without network assistance The SIM33ELa has excellent low power consumption characteristic(acquisition 25mA, tracking 20mA). SIM33ELA Supports various location and navigation applications, including autonomous GPS, GLONASS, GALILEo, QZsS, SBAS ranging (WAAS, EGNOS, GAGAN, MSAS), DGPS(RTCM) and A-GPS Key features e GNSS receiver supports GPS, GLONASS, GALILIRO, QZss, SBAs ranging (WAAS/EGNOS/MSAS/GAGAN, DGPS(RTCM) 33tracking/99 acquisition-channel Small footprint: 9.6x 14x 2.15mm, 31-pin LCC package o 12 multi-tonc activc intcrfcrencc cancellers and jammin g imination Indoor and outdoor mulli- path detection and compensation o Max NMea update rate up to 10 HZ o Advanced software features 1.
