GPS antenna - GLONASS high performance that supports the SBAS system (WAAS, EGNOS, MSAS). SBAS (Satellite Based Augmentation System) systems are innovative systems related to satellite navigation whose purpose is to provide GPS and GLONASS receivers with additional information that allows to "correct the error" of the received positioning data. The internal 50-channel positioning processor allows a first localization time (TTFF) of less than one second, while the data acquisition engine, specially designed for nautical use, allows numerous multiple time / frequency searches for immediate satellite tuning. The innovative design and receiver technology eliminate sources of interference and mitigate multiple signal effects, giving excellent navigation performance even in the most adverse weather conditions. Earnings 27 dB. Power supply, coming from the instrument, on coax cable from 2.5 to 5.5 Vdc. Connecting cable Connected by 10 mt. Dim.mm. 110 x 74 X 116 h
