(8) Any information provided in the Remarks line will be stored in the Amver’s automatic data processing system for<br />
later review. However, no immediate action will be taken, nor will the information be routinely passed to other<br />
organizations. The remarks line cannot be used as a substitute for sending information to other search-and-rescue<br />
authorities or organizations. However, Amver will, at the request of other SAR authorities, forward remarks line<br />
information to the requesting agencies.<br />
(9) Next report information is not currently used by the Amver System, but is expected to aid in future development.<br />
DIFFERENTIAL GLOBAL POSITIONING SYSTEM (DGPS)<br />
Since May 2000, Full Operational Service (FOS) of the <strong>Canadian</strong> <strong>Coast</strong> <strong>Guard</strong> DGPS service has been available from 19<br />
DGPS stations located on the East and West coasts of Canada and parts of the Great Lakes. DGPS corrections are<br />
broadcast from medium frequency (MF) radiobeacon transmitters located to cover selected marine areas and waterways.<br />
The broadcasts are in accordance with international standards for radiobeacon DGPS services. DGPS provides continuous<br />
precise positioning of better than 10 metres for 95% or better of the time (provided that suitable DGPS receiver equipment<br />
is utilized, properly installed and maintained).<br />
Additional information on the use of the DGPS service will be announced through Notices to Mariners. General<br />
information is also available from the CCG Website: http://www.ccg-gcc.gc.ca/dgps/main_e.htm<br />
The corrections from the DGPS service are calculated at the reference station in the NAD 83 coordinates. To process the<br />
information properly, DGPS receivers should be adjusted to the WGS 84 setting. Although WGS 84 and NAD 83 are<br />
essentially the same (only a few centimetres difference), it is highly recommended that all DGPS receivers be set to WGS<br />
84 to take full advantage of the precision of DGPS. When utilizing charts other than NAD 83, DGPS latitude and<br />
longitude positions must be adjusted to the appropriate datum using the information contained in the charts.<br />
The table that follows provides information on existing DGPS broadcasts. A list of United States <strong>Coast</strong> <strong>Guard</strong> (USCG)<br />
DGPS transmitters providing coverage in <strong>Canadian</strong> waters may be obtained directly from the USCG.<br />

Figures 1, 2 & 3 show the nominal coverage from existing broadcast stations. Users should be aware that coverage is<br />
subject to short and long term variations due to environmental and seasonal conditions.<br />
