供应麗台 Leadtek LR9132 SiRF IV GPS模組 GPS Module GPS Engine Board

Introduction
The LR9132 is a high sensitivity, low power ,Surface Mount Device (SMD), that fully utilized SiRF star IV upgraded features. This 48-channel global positioning system (GPS) receiver is designed for a wide range of OEM applications then based on the GPS signal search capabilities of SiRFstarIV GSD4e ROM chipset, SiRF’s newest chipset technology.
The LR9132 provides flexible bus interface (Optional : UART , I2C or SPI ).
LR9132 is designed to allow quick and easy integration into GPS-related applications such as:
- Mobile gaming
- Cellular handsets
- Cameras
- Asset Tracking
- Other location-aware consumer devices Premium on-chip software provides a new level of continuous location awareness by employing.
- Opportunistic ephemeris decode and advanced power management, which enable the GPS receiver to stay in a hot-start condition nearly continuously while consuming very little power.
- *2 Full support for client-based and server-based SiRFInstantFixTM
- *3 Dynamic contextual awareness, temperature monitoring, and MEMS sensors that work in concert to conserve power and boost performance
(*2/*3, Above features should be combined with external EEPROM, please refer to application note.)
- Use of software control modules to achieve power saving state

Features
Performance
- High Performance Solution:
   - High sensitivity navigation engine (PVT) tracks as low as -163dBm
   - 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) – Need operator support
- *4 Embedded CGEE / SGEE (Need b server support) speed up TTFF a lot and makes cold start time to be around 22 seconds
- SiRFGeoRecovTM Reverse EE makes positioning process being done under power saving mode.
- Reacquisition Time : 0.1 second
- RF Metal Shield for best performance in noisy environments
( *4, Above features should be combined with external EEPROM, please refer to application
note. )

Hardware and software
- Based on the high performance features of the SiRF Star IV low power single chipset.
- Adaptive Micropower Controller :
  -    Only 50 to 500 μA maintains hot start capability.
  -    <10mW required for TricklePowerTM modeRoHS compliant (lead-free)
- SMT pads allow for fully automatic assembly processes equipment and reflow soldering
- Advanced Navigation Feature :
  -    Smart sensor I2C interface
  -    Interrupt input for context change detection

Advantages
- Built-in LNA.
- Built-in internal ROM and based on Firmware 4.5.x
- *5 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 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 -159 dBm sensitivity)
- Support SiRFaware technology
- Support adaptive “Micro Power Controller” power management mode
- *6 Support MEMS sensor through I2C interface. (V4.5.X firmware is available for now)
- 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
- 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
( *5/*6, Above features should be combined with external EEPROM, please refer to application note. )
