FIRSTGPS ARCHITECTURE HIGHLIGHTS
FUNCTIONAL BLOCK DIAGRAM
INDUSTRY LEADING GPS PERFORMANCE
LOW POWER
RGPSM002 GPS RECEIVER HIGHLIGHTS
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 canyon performances
Position accuracy: < 5m CEP (50%) without SA (horizontal)
Warm Start is under 32 seconds (50%)
Hot Start is under 12 seconds (50%)
Timing output accuracy: +/- 100 ns
Ultra low power integrated circuit design, optimized RF and DSP architectures, 19 mA @ 3V tracking/doing
fixes
Further power saving thanks to 3 different power down modes
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
PPS output
On-board RTC can be supplied by a separate back-up power supply if the main supply is turned off.
Application software can be customized for high volume applications (Flash memory)
