25、nce standards, methods of testing and required test results for GPS shipborne receiver equipment, based on IMO Resolution MSC.112(73), which uses the signals from the United States of America, Department of Defence (US DOD), Global Positioning System (GPS) in order to determine position. A descripti
26、on of the GPS SPS is given in the normative reference GPS, SPS signal specifi- cation USA Department of Defence 3rd Edition October 2001. This receiver standard applies to phases of the voyage “other waters“ as defined in IMO Resolution A.529(13). All text of this standard, whose meaning is identica
27、l to that in IMO Resolution MSC.112(73), is printed in italics and the Resolution and paragraph number indicated between brackets i.e. (M.112/A1.2). The requirements in clause 4 are cross-referenced to the tests in clause 5 and vice versa. 2 Normative references The following referenced documents ar
