Reelektronika's generation of LORADD receivers marks the start of a new era in eLoran receiver technology. Drawing from its long history of experience in the field of Loran, Reelektronikasuccessfully implemented unprecedented digital signal processing algorithms on a newly designed, compact yet powerful DSP platform.

Navigation

LORADD receivers can output independent eLoran positions, enhanced by the use of ASF maps where available. However, LORADD technology can also take full advantage of an integrated or optionally externally connected GPS receiver. In this case, the GPS receiver provides additional raw measurements to the LORADD. The LORADD then combines its own eLoran measurements with the GPS measurements, and outputs a so-called 'integrated position solution', taking full advantage of the strong points of both navigation systems.

Measurements

Designed for high performance, the LORADD is capable of outputting independent measurements at user selectable intervals. Measurements on eLoran time-of arrival, ECD and signal quality are output. Also, accurate true-North heading info based on eLoran is available even if the receiver is stationary.

Interfacing

Through the serial ports, the receiver is fully customizable to output all required measurements on any of the serial ports. A Windows® software package is supplied for easy interfacing. The receiver's interface is according to NMEA standards. Relevant NMEA messages and proprietary messages in NMEA format can be used in parallel for flexible receiver operation and easy connection to other navigation equipment.
