Annex 2
RECOMMENDATION ON PERFORMANCE STANDARDS FOR SHIPBORNE DGPS AND DGLONASS MARITIME RADIO BECON RECEIVER EQUIPMENT†
1 INTRODUCION
1.1 Differential services broadcast information for augmenting the Global Positioning System (GPS) and the Global Navigation Satellite System (GLONASS) provide the accuracy and integrity required for entrances and harbour approaches and other waters in which the freedom to manoeuvre is limited. Various service providers are broadcasting differential information applicable localized areas. Different services provide information for augmenting GPS, GLONASS, or both.
1.3 This standard covers the basic requirements of maritime radio beacon receiver equipment providing augmentation information to position-fixing equipment. It does not cover other computational facilities which may be in the equipment.
2 DGPS AND DGLONASS MARITIME RADIO BEACON RECEIVER EQUIPMENT
The words "DGPS and DGLONASS maritime radio beacon receiver equipment" as used in this Performance Standard includes all the components and units necessary for the system to properly perform its intended functions. The equipment should include the following minimum facilities:
.1 antenna capable of receiving DGPS or DGLONASS maritime radio beacon signals;
.2 DGPS and DGLONASS maritime radio beacon receiver and processor;
.3 receiver control interface; and
.4 data output interface.
3 FUNCIONAL REQUIREMENTS
3.1 The DGPS and DGLONASS maritime radio beacon receiver equipment should:
