The new RTKDuo instrumented buoy associated with the AQUA-METRE R300NG USBL offers
a very accurate, light and hassle-free way to provide underwater georeferenced position.
The instrumented buoy includes: a dual antenna GNSS RTK Receiver (to measure the
position and heading of the buoy), a mem’s motion reference unit to measure the pitch
and roll and filter the noisy GNSS heading, a radio-modem (ISM band, 868 or 915MHz)
to manage the buoy from the survey PC. The internal buoy processor synchronises
all sensor, including the AQUA-METRE R300-NG USBL in order to deliver geographic
position of underwater transponder like the MiniPointer R300-NG (directly outputing
$GGA NMEA messages).
The AQUA-CAD software, when associated with the RTKDuo buoy, offers the usual cartographic
projections like UTM.
