Ct-434 GPS 模組

更新時間:

產品內容

The Ct-G434 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 ROM chipset, SiRFs newest chipset technology. The Ct-G434 provides flexible I/O interfaces (UART , I2C and SPI which can be defined by customer). Ct-G434 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         High Performance Solution:

- High sensitivity navigation engine (PVT) tracks as low as -160dBm

- 48 track verification channels

- SBAS (WAAS or EGNOS)

u         Active Jammer Remover:

- Removes in-band jammers up to 80 dB-Hz

- Tracks up to 8 CW jammers

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

u         *2 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

( *2, Above features should be combined with external EEPROM, please refer to application note. )

 

Interface

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

u         Secondary I2C port for MEMS connection

u         Protocol: NMEA-0183 (default)

 

 

Advantages

u         Built-in LNA.

u         Built-in internal ROM and based on Firmware 4.x.x

u         *3 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.

u         Support SiRF Aware technology

u       Support adaptive “Micro Power Controller” power management mode

u       *4 Support MEMS sensor through I2C interface. (V4.X.X firmware is available for now)

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         Suitable for battery drive devices that need lower power consumption application
