OEM GPS Receiver Module
GPSM001
FIRSTGPS ARCHITECTURE HIGHLIGHTS
INDUSTRY LEADING GPS PERFORMANCE
- Builds on high performance FirstGPS core
- Satellite signal tracking engine to perform GPS acquisition and tracking functions without CPU intervention
- High sensitivity: to -143 dBm tracking, superior urban performance
- Position accuracy: < 5m CEP (50%) without SA (horizontal)
- Warm Start is under 40 seconds (50%)
- Hot Start is under 12 seconds (50%)
- Timing output accuracy: +/- 400 ns
LOW POWER
- Ultra low power integrated circuit design, optimized RF and DSP architectures, < 17mA @ 3.3V tracking/doing
fixes
- Further power saving thanks to 3 different power down modes
o Power Save – RF section and GPS engine turned Off
o Stand-by – RF section, GPS engine, and MCU clock turned Off, main power supply On, RTC running
o Power down - RF section, GPS engine, and MCU clock turned Off, main power supply Off, RTC
running on the back-up supply
XE1610-OEMPVT GPS RECEIVER REFERENCE DESIGN HIGHLIGHTS
- Embedded AT91 MCU, ARM7TDMI-based
- Small form factor
- Low cost
- Ready-to-plug solution, fully autonomous PVT solution. Easily integrated into existing systems
- High signal acquisition & tracking performances
- On-board RAM for GPS navigation data. On-board Flash memory is used to back-up data such as the Almanac
