1.3 OVERVIEW
The GPS 16x series products are complete GPS sensors including embedded receiver and antenna, designed for a
broad spectrum of Original Equipment Manufacture (OEM) system applications. Based on the proven technology
found in other Garmin GPS receivers, the GPS 16x tracks multiple satellites at a time while providing fast time-to-
first-fix, one-second navigation updates, and low power consumption. This generation of GPS sensors includes the
capability of FAA Wide Area Augmentation System (WAAS) differential GPS.
The GPS 16x design uses the latest technology and high-level circuit integration to achieve superior performance
while minimizing space and power requirements. All critical components of the system including the RF/IF receiver
hardware and the digital baseband are manufactured by Garmin to ensure the quality and capability of the GPS. The
hardware capability combined with software intelligence makes the GPS 16x easy to integrate and use.
The GPS 16x series products are designed to withstand rugged operating conditions and are waterproof to IEC
60529 IPX7, immersion in 1 meter of water for 30 minutes. These complete GPS receivers require 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. The system may communicate with the GPS via an
asynchronous serial communications port. 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 or RTCM corrections yielding 3- to 5-meter position
accuracy (see section
1.5 Technical Specifications).
• Compact, rugged design ideal for applications with minimal space.
• May be remotely mounted in an out-of-the-way location.
• 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
section 4.1 Received
NMEA 0183 Sentences
).
• Highly accurate one-pulse-per-second (PPS) output for precise timing measurements. Pulse width is
configurable in 20-millisecond increments from 20 ms to 980 ms with 1 μs accuracy.
• Configurable for binary format data output on COM1 port.
• Flexible input voltage levels of 3.3 Vdc to 6.0 Vdc with over-voltage protection in the GPS 16xLVS, and
8.0 Vdc to 40 Vdc in the GPS 16xHVS.
• FLASH-based program with new software revisions available through Web site download.
• Non-volatile memory does not require battery backup.
• Waterproof design allows continuous exposure to the prevailing weather conditions at most locations.
