Ct-G433 GPS 模組

CarandMarine/FleetManagement/AssetTracking/AVLandLocation-BasedServices

The Ct-G433 is a high sensitivity, low power and very compact smart antenna module, with built in GPS receiver. This 48-channel global positioning system (GPS) receiver is designed for a wide range of OEM applications then based on the fast and deep GPS signal search capabilities of SiRFstarIV GSD4e architecture, SiRFs newest chipset technology. The Ct-G433 provides flexible I/O interfaces (UART , I2C and SPI which can be defined by customer).

Ct-G433 is designed to allow quick and easy integration into GPS-related applications such as:

n           PDA, MID, and other portable devices

n           Car and Marine Navigation

n           Fleet Management / Asset Tracking

n           AVL and Location-Based Services

n           Hand-Held Device for Personal Positioning and Navigation

 

 

Features

Performance

u         Highest performance GPS PVT engine

u         High acquisition sensitivity for fast TTFF

u         Extremely low weak signal tracking sensitivity

u         Highest integration with small and compact from factor

u         Value added software enhancements

u         Multimode A-GPS (Autonomous, MS-Based, and MS-Assisted) – With operator support

u         Embedded CGEE / SGEE (With back-end server support) speed up TTFF a lot and makes cold start time to be around 20+ seconds.

u         SiRFGeoRecovTM Reverse EE makes positioning process being done under power saving mode.

u         RF Metal Shield for best performance in noisy environments

 

 

Interface

u         Multiple host interfaces (UART, I2C, and SPI)

u         Secondary I2C port for MEMS connection

u         Protocol: NMEA-0183

 

 

Advantages

u         Built-in LNA.

u         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.

u         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.

u         Tracking sensitivity as low as -163dBm, even without network assistance. (SiRF StarIII has only -159dBm sensitivity)

u         Support SiRF Aware technology

u       Support adaptive “Micro Power Controller” power management mode

u       Support MEMS sensor through I2C interface

u       MEMS interrupt can improve Micro Power Mode performance.

u       Only 8mW Trickle Power, so user can leave power on all day instead of power off

u         SBAS Ranging : SBAS satellite measurements will be used un the navigation solution for improved DOP and coverage. (firmware V4.1.0 or later will be support)
