DGPS SITE CONFIGURATION INFORMATION

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. Please report DGPS problems or outages at our report-a-problem page. Thank you in advance.

Notes:
