Hardware
Our rjab CORS system operates with 12 channel, 10hz, dual frequency GPS receiver (Leica GRX1200) and a geodetic quality antenna , capable of providing up to 3mm +/- 0.5 ppm accuracy in a post processed static mode.

GPS Antenna Position and Site Log
GPS Antenna Position: The GPS antenna position was computed by The National Geodetic Survey's OPUS (Online Positioning User System) service using 18 hours of data. We are in the process of including rjab into the Cooperative CORS system. This process takes 60-90 days to complete. As soon as we have completed the process the position will be updated slightly and included in the NGS database.

RINEX Data
The RINEX GPS data contained in this site is in a zip RINEX format. The data is kept for the most recent 30 days in this site. The 31st day is automatically archived and then removed from this site. You may contact us for data older than 30 days. Please note a fee may be involved on an archived data request, based on the age, amount of data requested and medium of transportation.
