GPS Marine Smart Antenna
High Sensitivity Marine Smart Antenna Full navigation accuracy provided by Standard Positioning Service (SPS). Support high sensitivity for very weak signal acquisition and tracking. Integrated powerful CPU, base band and RF front-end hardware in a SOC (System On Chip) design reduces the space and power consumption in state of the art. Advanced IC technology gets the total receiver cost saving. Allow the receiver to track up to 12-channel satellites. Fast TTFF for cold start, warm start and hot start. High performance firmware drives an excellent positioning speed. Serial communication channel with user selectable baud rates allow to design the maximum interface capability and flexibility. Support backup power to sustain internal clock. Fit for Fishfinder, Navigator ,Digital Clock,PC and so on SPECIFICATIONS Accuracy: Position: 5m w/o S/A Velocity: 0.1 m/sec w/o S/A Time: 1u sec Acquisition: Cold start: 50 sec(Average) Warm start: 35 sec (Average) Hot start: 2 sec (Min.) Sensitivity: Acquisition: -139 dBm Tracking: -152 dBm Dynamics: Altitude: max. 18,000m Velocity: max. 500m/sec Acceleration. max. 4g Navigation update rate: Once per second Serial I/O : RS-232 or RS-422 (Optional) 4.8K (optional 9.6K) NMEA 0183:GGA, GSV,GSA, RMC,(optional VTG,GLL) Coordinate Datum: WGS 84 Power supply : +9VDC and up to +34V DC Power consumption: Typical (tracking): 150mW System Performance : Tracks up to 12 satellites L1, C/A code Operating Temp.: -40 X ~ +85 XC Storage Temp.: -55 X ~ +100 XC Humidity: 5%~95%
