The ORG4500-R01 from OriginGPS is a miniature multi-channel GNSS (GPS+GLONASS, SBAS, QZSS) receiver that continuously tracks all satellites in view, providing real-time positioning data in standard NMEA format. The device has a rapid time to first fix (TTFF) of less than one second, accuracy of approximately two meters, and tracking sensitivity of -163 dBm.
The module has an integrated dual-stage LNA, SAW Filter, TCXO and RTC crystal shield with the Multi-constellation SiRFstar V™ GPS SoC. It is available in a package that measures 4.1 x 4.1 x 2.1 mm and is ideal for ultra-compact applications such as smart watches, wearable devices, trackers and digital cameras.
This GNSS receiver can detect changes in context, temperature, and satellite signals by maintaining and opportunistically updating its internal fine time, frequency and ephemeris data, thereby achieving a state of near continuous availability, while consuming mere microwatts of battery power.
