GPS Receiver Standard GPS with 1-second (1 Hz) update rate that outputs NMEA 0183 info Fast update GPS with 1/10-second (10 Hz) update that outputs NMEA 0183 info Fast update GPS with a 1/10-second (10 Hz) update that outputs 8- or 16-pulse signal to drive existing electrical speedos on the market Key Features 1 Hz unit outputs NMEA 0183 data at 4800 baud, 8 data bits, 1 stop bit, no parity (NMEA 0183 standard) 10 Hz unit outputs same NMEA messages at 38,400 baud Receiver output is a differential signal to meet NMEA 0183 specs. (The input on the speedo head is an opto-coupled NMEA 0183 differential input.) Operating voltage is 10-32V DC; unit typically consumes ,50mA at 12V Operating temperature -30 to +85 degrees C, storage -40 to +125 degrees C Cold/warm/hot start times are <35/<34/<1 seconds 66 channels for acquisition, 22 for simultaneous tracking Position accuracy is “<3m CEP (50%) without SA (horizontal)” or “3.0m 2D RMS” Velocity accuracy is “0.1m/s without aid” The default NMEA output messages are GGA, GSA, RMC, VTG, and GSV For 8/16 pulse unit only: The pulse output is a square wave, low voltage should be <0.5V, high voltage will be (supply-0.5)V. Part # Standard update with 25’ harness and no connector (the connector is supplied separately so you can feed this long wire through tight areas and then add the connector) Standard update with 4’ harness and no connector Standard update receiver with 4’ harness with connector attached Fast update NMEA 0183 4’ harness with connector attached Fast update NMEA 0183 4’ harness and no connector Fast update NMEA 0183 25’ harness and no connector Fast update 8/16 pulse output with 4’ harness and ring terminals to connect to threaded #8-32 studs on existing electric speedos (non-GPS speedo heads) 4 pins and connector for units without connector to attach to the Veethree GPS speedometer gauge VEETHREE ELECTRONICS 2050 47th Terrace East Bradenton, FL 34203
