Introduction
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 ephemer is 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 SiRFInstantFixTM
- 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
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.
