OVERVIEW
The GPS 15 is part of Garmin’s latest generation of GPS sensor boards designed for a broad spectrum of
OEM (Original Equipment Manufacture) system applications. Based on the proven technology found in
other Garmin 12-channel GPS receivers, the GPS 15 tracks up to 12 satellites at a time while providing fast
time-to-first-fix, one-second navigation updates, and low power consumption. The far-reaching capabilities
of the GPS 15 meet the sensitivity requirements of land navigation as well as the dynamics requirements of
high-performance aircraft.
The GPS 15 design utilizes 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 15 easy to integrate and use.
Being a complete GPS receiver, the GPS 15 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, an active
GPS antenna, and a clear view of the GPS satellites. The system may communicate with the GPS 15 via its
3.3V CMOS-level serial port. The GPS 15 stores data such as satellite orbital parameters, last-known
position, and date and time in battery backed up SRAM. End-user interfaces, such as keyboards and
displays, are the responsibility of the application designer.
