DGPS SITE CONFIGURATION AND OUTAGE INFORMATION
Outage information is shown next to each site. It is requested that users notify the Navigation
Information Services Watchstander at (703) 313-5900 or via email
regarding any observed outages, problems, or requests.
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 messages.
Note: The Omaha DGPS beacon (298 KHz, Site ID 868) terminated at 1500Z (1100EST) May 15, 2013. For further inquiries, please contact the Navigation Information Service (NIS) via our Contact Us page or via phone at 703-313-5900.
