3. Practical difficulties with Differential Correction Systems
Taking into-account the fact that some Member States had experienced difficulties meeting the requirements of resolution A.815(19), IALA(International Association of Lighthouse Authorities) offered to analyse these standards, including their definitions and levels, and inform the Organization accordingly
Relevant IEC standards will be revised later on.
4. Revision of performance standards for Shipborne Satellite Radio Navigational Receivers
The Technical Working Group considered the IEC proposal (NAV 45/7/5) on Review of performance standards for shipborne satellite radionavigational receivers - Proposed amendments to resolution A.819(19) and MSC.64(67). annex 2 and its report will be submitted to NAV 46 for further consideration and action, as appropriate.
Relevant IEC standards will be revised later on.
5. Development of performance standards for Night Vision Equipment for High-speed Craft
The Sub-Committee considered the report of the Technical Working Group at NAV 44 (NAV 45/7, paragraph 2.3, annex 1 ) and the comments submitted by ISO (NAV 45/7/3) and agreed the draft performance standards for night vision equipment for High-Speed Craft given in NAV45/WP. 2 Annex 2, for adoption by the Committee.

6. Development of performance standards for Daylight Signalling Lamps
The Sub-committee, having considered the report of the Technical Working Group at NAV 44 (NAV 45/7, paragraph 2.4 to 2.6, annex 2, agreed the draft performance standards for daylight signalling lamps, given in annex NAV 45/wp. 2 Annex 3, for adoption by the Committee.
7. Revision of performance standards for Devices to indicate Speed and Distance
The Sub-Committee considered NAV 45/7/1 (IEC), NAV 45/7/6 (United Kingdom), NAV 45/7/7 (Sweden) and MSC 71/20/10 (IEC) and after considerable discussion agreed the revised performance standards for devices to measure and indicate speed and distance, given in NAV45/WP. 2 Annex 4, for adoption by the Committee.
The delegation of Bahamas, supported by the delegations of Australia, Greece, Panama and the ICS (International Chamber of Shipping) representative, was of the opinion that the minimum requirement for devices to measure and indicate speed and distance, which are intended for general navigation, ship manoeuvring and anti-collision use, should be - "to provide information on the distance run and the forward speed of the ship through the water" only.
Relevant IEC standard (IEC 61203) will be revised later on.
