APOS GPS 36 Specification

Basic

u     GPS chipset: Sony CXD2951GA-4 Single chip

u     Channel:12-channel GPS receiver capable of simultaneously receiving 12 satellites

u     Reception frequency: 1575.42MHz (L1 band, CA code)

u     Dimension: 73.4 x 39.0 x 18.9 mm (L x W x H)

u     3-color LED status indicators:

•  GPS status: The green LED will be lit when the GPS receiver is in acquisition mode, and will start blinking every 2 seconds when the GPS position is fixed (i.e., during tracking mode)

•  Bluetooth status: The blue LED will be lit once per two seconds when the Bluetooth is in connection and be lit 0.1 second every 7.9 seconds if the Bluetooth connection between the host and ABG10868 is lost or in standby mode

•  Battery status: The red LED will be blinking to indicate the battery power level is low, on when charging the battery and off if the battery is fully charged

u Switch and connectors:

•  Power switch: Turn on/ off the ABG10868

•  Reset button: To initialize the GPS receiver

•  Power jack: Connect to external power or car charger

TTFF (Time to First Fix)

u     Time until initial position measurement after power-on with the following conditions:

•  Cold Start (without both ephemeris and almanac time): 45s (average) / 60s (95% possibility)

•  Warm Start (without ephemeris but with almanac time): 35s (average) / 40s (95% possibility)

•  Hot Start (with both ephemeris and almanac time): 2s (average) / 6s (95% possibility)

* Reference data with elevation angle of 5° or more and no interception environment with satellite powers ≧ -130dBm

* “95% possibility” means “position time with 95% possibility”

Positioning accuracy:

u     2DRMS: approx. 2m

* Reference data with elevation angle of 5° or more and no interception environment with satellite powers ≧ -130dBm

Sensitivity:

u     Tracking sensitivity: -152dBm (average) or less

u     Acquisition sensitivity: -139dBm (average) or less in Normal mode

Measurement data update time:
