This International Standard specifies the minimum performance standards, methods of testing and required test results for GLONASS shipborne receiver equipment, based upon the IMO Resolution MSC.53(66), which use the signals from the Russian Ministry of Defence Global Navigation Satellite System (GLONASS), in order to determine position. This receiver standard applies to phases of the voyage in "other waters" as defined in IMO Resolution A.529. All the text of this standard, whose meaning is identical to that in IMO Resolution MSC.53(66) will be printed in italics and the Resolution and paragraph number indicated between brackets. The requirements in clause 4 are cross-referenced to the tests in clause 5 and vice versa.
