The ORG4472 from OriginGPS is a GPS Receiver Module for GPS and QZSS constellations with SBAS (WAAS, EGNOS, MSAS) support. It is a miniature multi-channel receiver that continuously tracks all satellites in view and provides accurate positioning data in standard NMEA format. The internal ARM CPU core and sophisticated firmware keep GPS payload off the host and allow integration in low resources embedded solutions. It is a complete SiP (System-in-Package) featuring advanced miniature packaging technology and an ultra-small footprint designed to commit unique integration features for high volume, low power and cost sensitive applications.
The module has a navigation sensitivity of -160 dBm and a tracking sensitivity of -163 dBm. This receiver has a cold start of under 35 s, a warm start of under 32 s and a hot start of under 1 s. It requires a DC supply of 1.8 V and consumes under 47 mA of current. This receiver module can be controlled via SPI, UART and I2C interfaces.
The ORG4472 is based on SiRFstarIV architecture and is optimized for indoor applications with periods of unobstructed sky view when moving from place to place. It can detect changes in context, temperature, and satellite signals to achieve a state of near continuous availability by maintaining and opportunistically updating its internal fine time, frequency, and satellite Ephemeris data while consuming mere microwatts of battery power.
The module has integrated SiRFstarIV GSD4e GPS processor, ARM7 109 MHz baseband CPU, LNA, SAW filter, TXCO and RTC. It supports OriginGPS’ Noise Free Zone System (NFZ) technology, multipath mitigation and indoor tracking. This module has an Active Jammer Remover that tracks up to 8 CW interferers. It supports Almanac Based Positioning (ABP) and Selectable NMEA or OSP (SiRF Binary) communication standards. The module supports power saving techniques like ATP, PTF and APM modes.
The ORG4472 is available in a surface-mount package that measures 7 x 7 mm and is ideal for emergency systems, precise timing, micro robots & UAVs, weather balloons, WiMAX base stations, Femto and Pico cells, industrial sensor platforms, workforce management, monitoring, mapping, automation, positioning, navigation, tracking and scientific applications.
