GPS/GLONASS/Galileo Receiver GPS SiRF V Engine Board Ct-G551

Features: - SiRF StarV ultra low power chipset - GPS, GLONASS, Galileo and SBAS reception for high GNSS availability and accuracy - Compact module size for easy integration : 15 x 14 x 2.8 mm - Fully utilized SS5 upgrade features The Ct-G551 GPS module is a high sensitivity, low power, Surface Mount Device (SMD) that fully utilized SiRFstarV upgraded features. This 48-channel Global Positioning System (GPS) and Global Navigation Satellite System (GLONASS) receiver is designed for a wide range of OEM applications and is based on the GPS signal search capabilities of the SiRFstarV CSRG05e ROM chipset, Serf’s newest chipset technology. The Ct-G551 provides flexible bus interfaces (UART).   Performance High Performance Solution : - GPS, GLONASS, Galileo and SBAS reception for high GNSS availability and accuracy - High sensitivity navigation engine (PVT) tracks as low as       GPS:-164dBm, GLONASS:-161dBm - 48 track verification channels - SBAS (WAAS or EGNOS,MSAS) - Active Jammer Remover: - Removes in-band jammers up to 80 dB-Hz - Tracks up to 8 CW jammers - Multimode A-GPS (Autonomous, MS-Based, and MS-Assisted) - Need operator support - Embedded CGEE / SGEE (With back-end server support) speed up TTFF a lot and makes cold start time to be around 20+ seconds. - SiRFGeoRecovTM Reverse EE makes positioning process being done under power saving mode. - Reacquisition Time: 0.1 second - RF Metal Shield for best performance in noisy environments Feature Item Description Chipset GSD5e/ROM base SiRF starV low power single chipset General Frequency GPS L1, 1575.42 MHz Frequency GLONASS L1, 1602~1615 MHz C/A code 1.023 MHz chip rate Channels 48 Sensitivity GPS -164 dB Sensitivity GLONASS -161 dB Accuracy Position <2.5 meters Velocity 0.01 meters/second Time 1 microsecond synchronized to GPS time Datum Default WGS-84 Other selectable for other Datum Time to First Fix(TTFF) (Open Sky & Stationary Requirements) Reacquisition 0.1 sec., average Snap start 1 sec., average Hot start 1~2 sec.
