GPS 15 Technical Specifications (P/N 190-00266-00) Rev. BPage 31.3 OVERVIEWThe GPS 15 is part of Garmin’s latest generation of GPS sensor boards designed for a broad spectrum ofOEM (Original Equipment Manufacture) system applications. Based on the proven technology found inother Garmin 12-channel GPS receivers, the GPS 15 tracks up to 12 satellites at a time while providing fasttime-to-first-fix, one-second navigation updates, and low power consumption. The far-reaching capabilitiesof the GPS 15 meet the sensitivity requirements of land navigation as well as the dynamics requirements ofhigh-performance aircraft.The GPS 15 design utilizes the latest technology and high-level circuit integration to achieve superiorperformance while minimizing space and power requirements. All critical components of the systemincluding the RF/IF receiver hardware and the digital baseband are designed and manufactured by Garminto ensure the quality and capability of the GPS. The hardware capability combined with softwareintelligence 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 anOEM or system integrator. A minimum system must provide the GPS with a source of power, an activeGPS antenna, and a clear view of the GPS satellites. The system may communicate with the GPS 15 via its3.3V CMOS-level serial port. The GPS 15 stores data such as satellite orbital parameters, last-knownposition, and date and time in battery backed up SRAM. End-user interfaces, such as keyboards anddisplays, are the responsibility of the application designer.1.4 FEATURES• 12-channel GPS receiver tracks and uses up to 12 satellites for fast, accurate positioning and lowpower consumption.• Compact, rugged design ideal for applications with minimal space.• May be remotely mounted in an out-of-the-way location.• User initialization is not required. Once installed, unit automatically produces navigation data.• On-board backup battery to maintain the non-volatile SRAM and real-time clock for up to 21 days.• Provision for external power to maintain the charge on the backup battery.• 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 2and 255 seconds).
