Overview
The GPS 18 series products include an embedded receiver and an antenna. Based on the proven technology
found in other Garmin 12-channel GPS receivers, the GPS 18 tracks up to 12 satellites at a time while
providing fast time-to-first-fix, precise navigation updates (five times per second for the GPS 18-5Hz, and
once per second for the GPS 18 USB, 18 PC, and 18 LVC), and low power consumption. This generation
of GPS sensors adds the capability of FAA Wide Area Augmentation System (WAAS) differential GPS.
The GPS 18’s far-reaching capability meets the sensitivity requirements of land navigation as well as the
dynamics requirements of high-performance aircraft.

The GPS 18 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 designed and manufactured by Garmin
to ensure the quality and capability of the GPS. The hardware capability combined with software
intelligence makes the GPS 18 easy to integrate and use.

The GPS 18 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. 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.

FEATURES
• 12-channel GPS receiver tracks and uses up to 12 satellites for fast, accurate positioning and low
power consumption.
• 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. Receiver position information can
be displayed directly on a chartplotter or PC.
• User initialization is not required. Once installed, unit automatically produces navigation data after
position fix is acquired.
• User-configurable navigation mode (2-dimensional or 3-dimensional fix).
• (GPS 18 LVC and GPS 18-5Hz only) Highly accurate measurement pulse output for precise timing
• (GPS 18 LVC and GPS 18-5Hz only) Highly accurate measurement pulse output for precise timing
measurements: one-pulse-per-second (1 Hz) for the GPS 18 LVC or 5 Hz for GPS 18-5Hz. Pulse width
is configurable in 20 millisecond increments from 20 ms to 980 ms with 1
is configurable in 20 millisecond increments from 20 ms to 980 ms with 1
µs accuracy.
• Configurable for binary format carrier phase data output.
• FLASH-based program and non-volatile memory. New software revisions available through Web site
• FLASH-based program and non-volatile memory. New software revisions available through Web site
download. Non-volatile memory does not require battery backup.
• Onboard rechargeable backup battery to maintain the real-time clock for up to 3 weeks.
• Configurable parameters include expected position, current time and date, preferred position fix type
• Configurable parameters include expected position, current time and date, preferred position fix type
(2D, 3D, or automatic), and velocity filter time constant (none, automatic, or your choice between 2
