"Warning : Although an antenna record was located in the RINEX file, no phase centre information could be found in the IGS/NGS file for your antenna. Estimated height should be used with caution. Ensure that both the antenna type and the RINEX header record “ANT # / TYPE " are valid.”
I assume this medant that the information is missing from the NGS database. However the RS2 appears in the database along with the calibration data.
Can the phase centre information be added manually to the header to rectify the processing error?
Thank you. I will try that. I had edited the RINEX headers in sublime text and zipped the .obs file and uploaded to NRCAN so had not needed rtkconv. I will use rtkconv then and if successful will continue that procedure.
