715 Center Street Grayslake IL 60030 NMEA 0183 GPS Receivers Three Surprisingly Affordable GPS Receiver/Antennas 1. Standard GPS with 1-second (1Hz) update rate HIGHLIGHTS 2. Fast Update GPS with 1/10 second (10Hz) udpate 3. Fast Update GPS with1/10 second (10Hz) udpate that outputs 8- or 16-pulse signal to drive existing electrical automotive or commercial speedos on the market • 1Hz unit outputs NMEA0183 data at 4800 baud, 8 data bits, 1 stop bit, no parity (NMEA 0183 standard). • 10Hz unit outputs same NMEA messages at 38,400 baud. • Receiver output is a signal to meet NMEA 0183 specs. [The input on the speedo head is an opto-coupled NMEA0183 input]. • Operating voltage is 10-32V DC; unit typically consumes <50mA at 12V. • Operating temperature -30 to +85°C, storage -40 to +125°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”. Part Number Standard update with 4 ft harness and ring terminals Fast 10 Hz 10x update with 4 ft harness with ring terminals Fast 10 Hz 10x update -8/16 pulse output with 4 ft harness and ring terminals to connect to threaded #8-32 studs on existing automotive or commercial electric speedos (Non -GPS speedo heads) • 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, h
