The LR9130P GPS module is a high sensitivity, low power, Surface Mount Device (SMD) that can be compatible to
LR9548SX or fully utilized SiRFstarIV upgrade features.
This 48-channel global positioning system (GPS) receiver is designed for a wide range of OEM applications and is based on the GPS signal search capabilities of the SiRFstarIV GSD4e chipset, SiRF’s newest chipset technology.
The LR9130P provides flexible I/O interfaces (UART is default, I2C and SPI by customer requirement).
The LR9130P is designed to allow quick and easy integration into GPS-related applications
such as:
- PDA, Pocket PC, Tablet and other computing devices
- Fleet Management /Asset Tracking
- AVL and Location-Based Services
- Hand-Held Device for Personal Positioning and Navigation
- All applications of battery drive device that needs lower power consumption
Hardware and Software
- Based on the high performance features of the SiRFstarIV GSD4e chipset
- Compact module size for easy integration: 24x20x2.9 mm (0.94x0.79x0.11 in)
- Hardware compatible with SiRF GSW4 software
- Multiple I/O pins reserved for customizing special user applications
- RoHS compliance
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)
- SiRFGeoRecovTM Reverse EE
- Cold/Warm/Hot Start Time: 35/35/1 sec. at open sky and stationary environments.
- Reacquisition Time: 0.1 second
- RF Metal Shield for best performance in noisy environments
Interface
- One TTL level serial port for GPS communications interface (UART is default, I2C and SPI by customer requirement)
- Protocol: NMEA-0183(default)
- Baud Rate: 4800 bps
