Garmin GPS 17x 기술 사양

1.3 OVERVIEW

The GPS 17x HVS is an embedded receiver and an antenna. Based on the proven technology found in other Garmin
GPS receivers, the GPS 17x HVS tracks multiple satellites at a time while providing fast time-to-first-fix, precise
navigation updates once per second, and low power consumption. This generation of GPS sensors includes the
capability of FAA Wide Area Augmentation System (WAAS) differential GPS.
The GPS 17x HVS design uses the latest technology and high-level circuit integration to achieve superior
performance while minimizing space and power requirements. The hardware capability combined with software
intelligence makes the GPS 17x HVS easy to integrate and use.
The GPS 17x 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 components
to be supplied by an OEM or system integrator. A minimum system must provide the GPS with a source of power
and a clear view of the GPS satellites. Internal FLASH memory allows the GPS to retain critical data such as
satellite orbital parameters, last-known position, date and time. End user interfaces such as keyboards and displays
are the responsibility of the application designer.

1.4 FEATURES

•
GPS receiver tracks and uses multiple satellites for fast, accurate positioning and velocity estimates.
•
Differential DGPS capability using real-time WAAS corrections yielding position errors of less than 3
meters.
•
Compact, rugged design ideal for applications with minimal space.
•
Factory configuration meets the needs of most systems that expect NMEA 0183 data from a GPS receiver.
Configuration commands are available to customize the NMEA 0183 output (see
NMEA 0183
Sentences)
•
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 μs 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.
