81.5.3.2 Acquisition Times Reacquisition: Less than 2 seconds Hot: Approx. 1 second (all data known) Warm: Approx. 38 seconds (initial position, time, and almanac known; ephemeris unknown) Cold: Approx. 45 seconds1.5.3.3 Update Rate 1, 5, or 10 records per second1.5.3.4 Accuracy GPS Standard Positioning Service (SPS)Position: < 15 meters, 95% typicalVelocity: 0.1 knot RMS steady state WAAS/EGNOS/MSASPosition: < 3 meters, 95% typicalVelocity: 0.1 knot RMS steady state Measurement Pulse Output Time: ±1 microsecond at rising edge of the pulse Dynamics: 999 knots velocity (only limited at altitude greater than 60,000 feet), 2g dynamics1.5.4 Interfaces1.5.4.1 GPS 19x HVS Electrical Characteristics Differential NMEA 0183 Serial, Compatible Polarity.o The default transmission rate is 38400 baud. If necessary, the rate can be limited to 4800 baud byinstalling the included resistor in series with the Accessory-ON wire. See the GPS 19x NMEA0183 Installation Instructions for more information.o The default position output rate is 10Hz. If necessary, the rate can be limited to 1Hz by installingthe included resistor in series with the Accessory-ON wire. See the GPS 19x NMEA 0183Installation Instructions for more information.NOTE: When connecting this antenna to a GPSMAP 2000, 3000, 4000, or 5000 series device,you must limit the update rate. If the update rate is not limited, the chartplotter might not receiveand display the GPS signal properly.1.5.4.2 Garmin InterfaceRefer to the Garmin Device Interface Specification found in the Garmin Device Interface SDK for informationabout the Garmin Interface. At the time of this printing, this document is located on the Garmin Web site at:www.garmin.com/support/commProtocol.html.1.5.4.3 GPS 19x HVS Protocol NMEA 0183 Version 3.01 (the factory default version) is programmable by data field 7 of the PGRMC1sentence described in section 4.1.4 Additional Sensor Configuration Information (PGRMC1). Available NMEA 0183 output sentences include GPALM, GPGGA, GPGSA, GPGSV, GPRMC, GPVTG,GPGLL, PGRME, PGRMF, PGRMM, PGRMT, PGRMV, and PGRMB (Garmin proprietary sentences).See section 4.2 Transmitted NMEA 0183 Sentences for format descriptions. Configuration and initialization is accomplished with NMEA 0183 input sentences. This allowsinitialization of information such as expected position, date, time, earth datum, and differential mode andconfiguration of operational parameters such as baud rate, positioning update rate, satellite system. Seesection 4.1 Received NMEA 0183 Sentences for format descriptions. Configurable for binary data output.1.5.4.4 Measurement Pulse Output 1 Hz pulse with programmable width, configurable in 20 ms increments from 20 ms to 980 ms. See section4.1.3 Sensor Configuration Information (PGRMC) for details about configuring the Measurement PulseOutput (or PPS) feature. 1 s accuracy for all conditions in which the GPS 19x HVS reported a valid and accurate position fix for atleast the previous 4 seconds.
