3、8 BSI 05-1999 ISBN 0 580 30409 4 National foreword This British Standard is the English language version of EN61108-2:1998. It is identical with IEC61108-2:1998. The UK participation in its preparation was entrusted to Technical Committee EPL/80, Marine navigation and radiocommunication equipment an
4、d systems, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and
5、promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. From1 January1997, all IEC publications have the number60000 added to the old number. For instance, IEC27-1 has been renumbered as IEC60027-1. For a period of time during the
6、 change over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their correspondin
7、g European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue

24、an 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
25、(66) will be printed in italics and the Resolution and paragraph number indicated between brackets. The requirements in clause4 are cross-referenced to the tests in clause5 and vice versa. 2 Normative references The following normative documents contain provisions which, through reference in this te
26、xt, constitute provisions of this part of IEC61108. At the time of publication, the editions indicated were valid. All normative documents are subject to revision, and parties to agreements based on this part of IEC61108 are encouraged to investigate the possibility of applying the most recent editi

32、mative reference of the GLONASS ICD specification. 4 Minimum performance standards 4.1 Object (53.66/1.3) Receiver equipment for the Global Navigation Satellite System (GLONASS) intended for navigational purposes on ships with maximum speeds not exceeding50kn shall, in addition to the general requir
33、ements contained in resolution A.694(17), comply with the following minimum performance requirements. (53.66/1.4) This standard covers the basic requirements of position fixing for navigation purposes only and does not cover other computational facilities which may be in the equipment. It is recogni
34、zed that other data inputs may be provided such as speed and distance measuring equipment (SDME), gyro or other navigational systems including GLONASS differential corrections. However, the basic minimum performance standards contained in this standard, pertain to the use of GLONASS signals for navi
35、gational position fixing only. Other computational activity, input/output activity or extra display functions shall not degrade the performance of the equipment below the minimum performance standards set out in this standard. The receiver shall comply with the provisions of IMO Resolutions A.529, A
36、.815, MSC.53(66), A.694 and IEC61162-1 and be tested in accordance with IEC60945.EN61108-2:1998 4 BSI 05-1999 4.2 (5.6.1) GLONASS receiver equipment 4.2.1 (53.66/2.1) The words “GLONASS receiver equipment” as used in this performance standard includes all the components and units necessary for the s
37、ystem to properly perform its intended function(s). The “equipment” shall include the following minimum facilities: a) antenna capable of receiving GLONASS signals; b) GLONASS receiver and processor; c) means of accessing the computed latitude/longitude position; d) data control and interface; e) po
38、sition display and, if required other forms of output. 4.2.2 The equipment may be supplied in one of several configurations to provide the necessary position information. Examples are: stand-alone receiver with means of accessing computed position via a keyboard with the positional information suita
39、bly displayed. GLONASS receiver feeding an integrated system with means of access to the computed position via an appropriate interface, and the positional information available to at least one remote location. The above examples should not be implied as limiting the scope of future development. 4.3
40、 Performance standards for GLONASS receiver equipment 4.3.1 (5.6.2) General (53.66/3.1.1) The GLONASS receiver equipment shall be capable of receiving and processing the Standard Positioning Service (SPS) signals of system GLONASS and provide position information in latitude and longitude SGS-90 (PZ
41、-90) co-ordinates in degrees, minutes and thousandths of minutes and time of solution referenced to UTC(SU). Means shall be provided to transform the computed position based upon SGS-90 (PZ-90) into WGS-84 or into data compatible with the datum of the navigational chart in use. Where this facility e
42、xists, the display shall indicate that the co-ordinate conversion is being performed and shall identify the co-ordinate system in which the position is expressed. NOTEThe IMO Resolution uses SGS-90 as the GLONASS datum. Since the time of the adoption of that Resolution the datum has been changed to
43、PZ-90. It is assumed that the IMO Resolution will be amended accordingly (see also4.3.2, 5.3, 5.5.2, and5.6.4.1.1). (53.66/3.1.2) The GLONASS receiver equipment shall operate on the Standard Positioning Service (on lettered L1 frequencies and C code). NOTEThe IMO Resolution MSC.53(66) is as in 53.66
44、/3.1.2 above. The Russian Federation prefer the following text “The GLONASS receiver equipment shall operate on the L1-sub-band frequencies with the standard precision navigation signal”. It is assumed that the IMO Resolution will be amended accordingly. 4.3.2 (5.6.3) Equipment output (53.66/3.1.3)
45、The GLONASS receiver equipment shall be provided with at least one output from which position information can be supplied to other equipment. The output of position information based upon SGS-90 (PZ-90) or WGS-84, shall be in accordance with IEC61162. NOTESentences for the GLONASS receiver output ar
46、e detailed in IEC61162-1. 4.3.3 (5.6.4) Accuracy 4.3.3.1 (53.66/3.1.4) The GLONASS receiver equipment shall have static accuracy such that theposition of the antenna is determined to100m(45m)(95%) with horizontal dilution of position (HDOP)# 4 (or PDOP# 6). 4.3.3.2 (53.66/3.1.5) The GLONASS receiver
47、 equipment shall have dynamic accuracy such that the position of the antenna is determined to within an accuracy of100m (45m) (95%) with HDOP# 4 (or PDOP# 6) under the conditions of sea state and ships motion likely to be experienced in ships (seeIMO Resolution A.694, IEC60721-3-6 and IEC60945). NOT
48、EThe IMO Resolution MSC.53(66) is as stated in4.3.3.1/4.3.3.2 above. The Russian Federation now state that the correct figure is45m in both cases and this figure will be used for testing purposes. It is assumed that the IMO Resolution will be amended accordingly. 4.3.4 (5.6.5) Acquisition (53.66/3.1
49、.6) The GLONASS receiver equipment shall be capable of selecting automatically the appropriate satellite transmitted signals for determination of the ships position with the required accuracy and update rate. (53.66/3.1.8) The GLONASS receiver equipment shall be capable of acquiring position to the required accuracy, within30min, when there is no valid almanac data. (53.66/3.1.9) The GLONASS receiver equipment shall be capable of acquiring position to the required accuracy, within5min, when there is valid alma
