2) GPS receiver + attena + translation cable. The GPS module features two GPS signal sensitivity modes: Standard and Enhanced. With Enhanced mode enabled, the module automatically switches to higher sensitivity when satellite signals are weak. On average, the sensitivity is about -154 dBm
KEY FEATURES
• 12-channel simultaneous operation
• Ultra-low power consumption: less than 90 mW (27 mA) @ 3.3 V
• Dual sensitivity modes with automatic switching
• Aided GPS through TSIP
• Antenna open and short circuit detection and protection
• Compact size: 26 mm W x 26 mm L x 6 mm H
• Supports NMEA 0183, TSIP, TAIP, RTCM SC-104 protocols

PERFORMANCE SPECIFICATIONS
General L1 (1575.42 MHz) frequency, C/A code, 12-channel,
continuous tracking receiver
Update Rate TSIP @ 1 Hz; NMEA @ 1 HZ; TAIP @ 1 Hz
Accuracy Horizontal: <5 meters (50%), <8 meters (90%)
Altitude: <10 meters (50%), <16 meters (90%)
Velocity: 0.06 m/sec
PPS (static): ±50 nanoseconds
Acquisition (Autonomous Operation in Standard Sensitivity Mode)
Reacquisition: <2 sec. (90%)
Hot Start: <10 sec (50%), <13 sec (90%)
Warm Start: <38 sec (50%), <42 sec (90%)
Cold Start: <50 sec (50%), <86 sec (90%)
Cold start requires no initialization. Warm start implies last
position, time and almanac are saved by backup power. Hot
start implies ephemeris also saved.
