45、quipment for the reception and proper de-modulating / decoding of differential GPS and GLONASS maritime radio beacon broadcasts (fully compliant with ITU-R M.823) intended for navigational purposes on ships with maximum speeds not exceeding 70 knots shall, in addition to the general requirements con

46、tained in resolution A.694(17), comply with the following minimum performance requirements.(114/1.2) As noted in Clause 1 Scope: This standard is applicable to HSC. This standard covers the basic requirements of maritime radio beacon receiver equipment providing augmentation information to position-

47、fixing equipment, including health messages. It does not cover other computational facilities which may be in the equipment.(114/1.3) Additional functionality (e.g. use of differential corrections and integrity, from multiple beacon reference stations, Eurofix, LORAN-COMM, VTS, FM subcarrier, commer

49、ary for the system to properly perform its intended functions. The equipment shall include the following minimum facilities:(114/2) 1) antenna capable of receiving DGPS or DGLONASS maritime radio beacon signals;(114/2.1) 2) DGPS and DGLONASS maritime radio beacon receiver and processor; (114/2.2) 3) receiver control interface; (114/2.3) (See also 4.3 2) 4) data output in
