61.2 OVERVIEWThe GPS 19x HVS is an embedded receiver and an antenna. Based on the proven technology found in other GarminGPS receivers, the GPS 19x HVS tracks multiple satellites at a time while providing fast time-to-first-fix, precisenavigation updates from once per second up to ten times per second, and low power consumption. This generationof GPS sensors includes the capability of FAA Wide Area Augmentation System (WAAS) differential GPS. Inaddition to the GPS satellite system, the GPS 19x HVS also supports simultaneous use of the Russian GLONASSsatellite system.The GPS 19x HVS design uses the latest technology and high-level circuit integration to achieve superiorperformance while minimizing space and power requirements. The hardware capability combined with softwareintelligence makes the GPS 19x HVS easy to integrate and use.The GPS 19x HVS is designed to withstand rugged operating conditions and is waterproof to IEC 60529 IPX7:immersion in 1 meter of water for 30 minutes. The complete GPS receiver requires minimal additional componentsto be supplied by an OEM or system integrator. A minimum system must provide the GPS receiver with a source ofpower and a clear view of the GPS satellites. Internal FLASH memory allows the GPS to retain critical data such assatellite orbital parameters, last-known position, date and time. End user interfaces such as keyboards and displaysare the responsibility of the application designer.Factory configuration meets the needs of most systems that expect NMEA 0183 data from a GPS receiver. GPS19xsupports two out of the box factory configurations. One is backward compatible with GPS17x operating atpositioning update rate of once per second and communicating at 4800bps. The other is operating at positioningupdate rate of 10 times per second and communicating at 38400bps. The two configurations are selectable with aresistor accessory wire. Configuration commands are available to customize the operation mode and NMEA 0183output (see section 4.1 Received NMEA 0183 Sentences)1.3 FEATURES GPS receiver tracks and uses multiple satellites for fast, accurate positioning and velocity estimates. Differential DGPS capability using real-time WAAS corrections (when WAAS is enabled) yieldingposition errors of less than 3 meters. GLONASS support. This receiver can also track and use multiple GLONASS satellites in addition to GPSsatellites. This increases positioning reliability in many situations due to higher total number of visiblesatellites. GLONASS is the Russian system of navigation satellites, similar to the United States’ GPS. 10Hz operation. Real position, heading and velocity updates of up to 10 times per second. Higherpositioning update rates may result in more accurate positioning. Compact, rugged design ideal for applications with minimal space. Two update-rate configurations available: 10 times per second at 38400bps and 1 time per second at4800bps. Highly accurate measurement pulse output for precise timing measurements: one-pulse-per-second (1 Hz).Pulse width is configurable in 20 millisecond increments from 20 ms to 980 ms with 1 s accuracy. Configurable for binary format data output. FLASH-based program allows new software revisions through a Web site download. Non-volatile memory does not require battery backup. Onboard rechargeable backup battery can maintain the real-time clock for up to 10 days. Configurable parameters include expected position, current time and date, and preferred position fix type(3D or automatic). Waterproof design allows continuous exposure to the prevailing weather conditions at most locations.
