BS EN 61108-1:2003

What is BS EN 61108-1- Receiver equipment for the Global Positioning System (GPS) intended for navigational purposes on ships about?  

BS EN 61108 discusses marine navigation and radiocommunication equipment, systems and global navigation satellite systems (GNSS). 

BS EN 61108-1 is the first part of the BS EN 61108 multi-series and discusses performance requirements, methods of testing and required test results of receiver equipment.  

BS EN 61108-1 covers the basic requirements of position fixing for navigation purposes only and does not cover other computational facilities which may be provided in the equipment.  

Who is BS EN 61108-1- Receiver equipment for the Global Positioning System (GPS) intended for navigational purposes on ships for? 

BS EN 61108-1 on receiver equipment for the Global Positioning System (GPS) intended for navigational purposes on ships is useful for: 

• Ship manufacturers  
• Shipowners  
• Shipborne radar and GPS manufacturers  
• Marine equipment manufacturers  
• Quality control personnel
• Inspection personnel 

Why should you use BS EN 61108-1 - Receiver equipment for the Global Positioning System (GPS) intended for navigational purposes on ships?  

Receiver equipment for the Global Positioning System (GPS) system intended for navigational purposes on ships with maximum speeds not exceeding 70 knots shall, in addition to the general requirements. 

BS EN 61108-1 contains the basic minimum performance standards for use of GPS Standard Positioning Service (SPS) signals for navigational position fixing, including differential corrections, and, in addition, for the determination of the speed and direction of the movement of the antenna over the ground. 

BS EN 61108-1 provides you with the minimum performance 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 the position. 

What’s changed since the last update?  

BS EN 61108-1:2003 supersedes BS EN 61108-1:1996, which is withdrawn. BS EN 61108-1:2003 includes some technical changes with respect to BS EN 61108-1:1996. These include: 

• It reflects the changes brought about by IMP adopting GPS as part of the carriage requirement on ships defined in SOLAS Chapter V 
• The new IMO performance standards, resolution MSC.112(73), replaced the previous issue, A.819(19), for new installations on the 1st of July 2002. This second edition of N 61108-1 incorporates revised tests for type approvals to the new performance standard 
• Changes include the need for data output to the EN 61162 series giving COG SOG and UTC with validity marking, operation during interference conditions and improved failure warnings
