2.9 The Sub-Committee was invited to consider annex 2 and submit it to the Committee for adoption.
DEVELOPMENT OF PERFORMANCE STANDARDS FOR DAYLICHT SIGNALLING LAMPS
2.10 The Working Group, having considered the report of the Technical Working Group at NAV 44 (NAV 45/7, paragraphs 2.4 to 2.6 and annex 2), agreed a draft MSC resolution on Performance standards for daylight signalling lamps, given in annex 3.
2.11 The Sub-Committee was invited to consider annex 3 and submit it to the Committee for adoption.
REVISION OF PERFORMANCE STANDARDS FOR DEVICES TO INDICATE SPEED AND DISTANCE (RESOLUTION A.824(19))
2.12 The Working Group considered NAV 45/7/1 (IEC), NAV 45/7/6 (United Kingdom), NAV 4517/7 (Sweden) and MSC 71/20/10 (IEC) and after considerable discussion agreed on a draft MSC resolution on Adoption of amended performance standards for devices to measure and indicate speed and distance, given in annex 4.
2.13 The Sub-Committee was invited to consider annex 4 and submit it to the Committee for adoption.
PROPOSED CHANGES TO THE SUB-COMMITTEE'S WORK PROGRAMME
2.14 The Sub-Committee was recommended to invite the Committee to delete the following agenda items:
.1 review of performance standards for devices to indicate speed and distance (resolution A.824(19));
.2 performance standards for night vision equipment for HSC and
.3 performance standards for daylight signalling lamps,
from the work programme of the Sub-Committee, as the work had been completed.
ITU MATTERS, INCLUDING RADIOCOMMUNICATION
ITU-R STUDY GROUP 8 MATTERS
2.15 The Working Group considered NAV 45/8 (Secretariat) containing the complete text of the Question approved by correspondence since the last Radiocommunication Assembly assigned to Study Group 8 (Question ITU-R No. 216-1/8 on Compatibility of radionavigation and radiolocation services operating in the bands 2900 - 3300 MHz and 5350 - 5650 MHz).
2.16 The Working Group was of the opinion that Question No. 216-1/8 concerned ITU compatibility studies of services operating in the band 2900 - 3300 MHz which is used in part by the shipping industry for 3 GHz (10 cm or S band) radars. It was realized that an increasing number of mobile communication service providers are making plans to operate in and around the 3 GHz radar band and that this band is under extreme threat. The band moreover is of great importance to the Organization because of the superior performance of 3 GHz radars under adverse environmental conditions; many ships use the 3 GHz radar as their primary radar. The SOLAS Convention, however, limits the mandatory requirement for radar to a 9 GHz (3 cm or X band) radar as this equipment provides compatibility with the SART for the GMDSS.
