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 ** 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 ** 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 ** interference when design-in the electrical device with noisy electrical ** 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
