Lr9334 Sirf Star Iv Gps Antenna Module Receiver Engine Board Ss4 Chipset - Taiwan

Features:

- SiRF StarIV internal ROM-based ultra low power chipset

- Compact module size for easy integration : 22 x 18 x 7 mm

- LR9334 smart antenna module

- Operating at 1.8V signal level

The LR9334 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, SiRF's newest chipset technology. The LR9334 provides flexible I/O interfaces (UART). LR9334 is designed to allow quick and easy integration into GPS-related applications such as:

- PDA, MID, and other portable devices

- Car and Marine Navigation

- Fleet Management / Asset Tracking

- AVL and Location-Based Services

- Hand-Held Device for Personal Positioning and Navigation

- Use of software control modules to achieve power saving state

SiRF IV GPS Module Features

Performance

- High Performance Solution:

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

- 48 track verification channels

- SBAS (WAAS or EGNOS)

- 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) -With operator support

- *2 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.

- RF Metal Shield for best performance in noisy environments

Interface

- Multiple host interfaces (UART)

- Secondary I2C port for MEMS connection

- Protocol: NMEA-0183 (default)

Advantages

- Built-in LNA.

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

- *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.

- 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.

- Tracking sensitivity as low as -160dBm, even without network assistance.

- Support SiRF Aware technology

- Support adaptive “Micro Power Controller” power management mode

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

- MEMS interrupt can improve Micro Power Mode performance.

- Only 8mW 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
