The U.S. Coast Guard DGPS service is available for positioning and navigation. Users
may experience service interruptions without advance notice. U.S. Coast guard DGPS broadcasts
should not be used under any circumstances where a sudden system failure or inaccuracy could
constitute a safety hazard. Differential corrections are based on the NAD83 (2011) position
of the reference station (REFSTA) antenna. Positions obtained using DGPS should be referenced
to NAD 83 coordinate system only. All sites are broadcasting RTCM Type 9-3 correction
**Note that NAVCEN is in the process of updating the integrity monitor positions
from NAD83 (CORS96) to NAD83 (2011).
