About the ORG4472 - SIRF 4 GPS Module
The ORG447X series module is industry’s smallest, autonomous, fully featured GPS engine.
The ORG447X series module is miniature multi-channel receiver that continuously tracks all satellites in view and provides accurate positioning data in industry’s standard NMEA format.
Internal ARM CPU core and sophisticated firmware keep GPS payload off the host and allow integration in low resources embedded solutions.
Featuring OriginGPS proprietary Noise-Free Zone System (NFZ™) technology the ORG447X offers
the ultimate in high sensitivity GPS performance in small size.
The ORG447XX series module is 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 ORG447X module incorporates new SiRFstarIV™ GPS processor.
The revolutionary SiRFstarIV™ architecture is optimized for how people really use location-aware products: often indoors with periods of unobstructed sky view when moving from place to place.
This new architecture 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 ephemeris data while consuming mere microwatts of battery power.
