GPS/GNSS Receiver Module, GPS/GLONASS Module, GNSS Engine Board, GNSS Solutions Ct-G551

Specifications

- GPS, GLONASS, Galileo and SBAS reception for high GNSS availability and accuracy
the Ct-G551 GPS/GNSS 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:
- 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
- Dynamic contextual awareness, temperature monitoring, and MEMS sensors that work in concert to conserve power and boost performance
- 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
- 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.
- SiRFGeoRecov Reverse EE makes positioning process being done under power saving mode. - Based on the high performance features of the SiRF Star V low power single chipset.
- SMT pads allow for fully automatic assembly processes equipment and reflow soldering
- 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)
- <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
- 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.
