• 12-channel GPS receiver tracks and uses up to 12 satellites for fast, accurate positioning and low power
consumption.
• Differential DGPS capability utilizing real-time WAAS or RTCM corrections yielding 3-5 meter
position accuracy (see Section 1.5.3.4).
• Compact, rugged design ideal for applications with minimal space. May be remotely mounted in an
out-of-the-way location. Receiver status information can be displayed directly on a chartplotter or PC.
• User initialization is not required. Once installed, unit will automatically transmit navigation data.
• User-configurable navigation mode (2-dimensional or 3-dimensional fix).
• 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.
• Configurable for binary format carrier phase data output on COM 1 port.
• Flexible input voltage levels of 3.3 to 5.0 Vdc (GPS 15L) or 8.0 to 40 Vdc (GPS 15H).
• Built-in backup battery to maintain real-time clock for up to 21 days. Provision for external power to
maintain the real-time clock for longer intervals.
• FLASH-based program and non-volatile memory. New software revisions upgradeable through web
site download and serial interface. Non-volatile memory does not require battery backup.
