SiRF Star IV GPS Module RS232 TTL Ct-G340 MCX Connector GPS engine board  

 
Product Description

 

Performance
- Highest performance GPS PVT engine
- High acquisition sensitivity for fast TTFF
- Extremely low weak signal tracking sensitivity
- High jamming immunity
- Smallest footprint and total solution size
- Highest level of BOM integration
- Value added software enhancements
- Multimode A-GPS (Autonomous, MS-Based, and MS-Assisted) – Need operator Support
- Embedded CGEE / SGEE (Need server support) speed up TTFF a lot and makes cold start time to be around 22 seconds.
- SiRFGeoRecovTM Reverse EE make positioning process being done under power saving mode.
- Reacquisition Time: 0.1 second
- RF Metal Shield for best performance in noisy environments

 

Interface
- UART interface
- Protocol: NMEA-0183(default)
- Baud Rate: 4800 bps (default)

- DIP type pitch 2.0mm- 2x10 pin header.
- Right angle MCX (RMCX) RF Connector.

 

Advantages
- Built-in LNA.
- 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 within 2 seconds just like hot start.
- 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 -163dBm, even without network assistance. (SiRF StarIII has only -159dBm sensitivity)
- 5 Hz Navigation Update Rate : User can select 1 Hz or 5 Hz navigation update rate. (V4.1.0 firmware will be support)
- SBAS Ranging : SBAS satellite measurements will be used in the navigation solution for improved DOP and coverage.(V4.1.0 firmware will support)
- 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
