Features: SiRF Star V 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). The Ct-G551 is designed to allow quick and easy integration into GPS-related applications such as: -Mobile gaming -Cellular handsets -Cameras -Asset tracking -Other location-aware consumer devices Premium on-chip software provides a new level of continuous location awareness by employing -Opportunistic ephemeris decode and advanced power management, which enable the GPS receiver to stay in a hot-start condition nearly continuously while consuming very little power -Full support for client-based and server-based SiRFInstantFix -Dynamic contextual awareness, temperature monitoring, and MEMS sensors that work in concert to conserve power and boost performance -Use of software control modules to achieve power saving state
SiRF V GPS Module Features Performance -Highest 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
Hardware and Software -Based on the high performance features of the SiRF Star V low power single chipset. -Adaptive Micropower Controller: -Only 50 to 500μA maintains hot start capability - <10mW required for TricklePower modeRoHS compliant (lead-free) -SMT pads allow for fully automatic assembly processes equipment and reflow soldering -Advanced Navigation Features: -Smart sensor I2C interface -Interrupt input for context change detection
Advantages -Built-in LNA -Built-in internal ROM and based on Firmware 4.1.X -It can remove in-band jammer up to 80db-Hz and track up to 8CW jammers, so the module can prevent GPS signal interference when design-in the electrical device with noisy electrical signal interferences such as Laptop, mobile phone, DSC, etc. -Maintain tracking sensitivity as low as GPS:-164dBm、GLONASS:-161dBm, even without network assistance. (SiRF StarIII has only -159dBm sensitivity) -Support SiRFaware technology : -Support adaptive “Micro Power Controller'power management mode. - <10mW Trickle Power, so user can leave power on all day instead of power off -Suitable for battery drive devices that need lower power consumption application -Ideal for high volume mass production(Taping reel package) -Cost saving through elimination of RF and board to board digital connectors -Flexible and cost effective hardware design for different application needs -Embed CGEE (Client Generated Extended Ephemeris) that can capture ephemeris data from satellites locally and predicts ephemeris out to 3 days. So if the module was off within 3 days, it could complete positioning process with limited time just like hot start.
