I have an Igage X-90 I am really happy with, and impressed by; the unit and the software are beyond expectations. Thank you Igage for marketing a unit for the occasional user. I've done about a dozen sessions, but on 2 sessions, got "Warning: standard deviations greater that 5 cm....problems at reference stations....(station) may be excluded...." so I selected the station furthest from the unit, and resubmitted, with slightly different, (better?) results, no warning. So, why doesn't OPUS RS cull out questionable stations in the solution? How can I determine, other than trial and error, what station(s) to exclude?
If you click the options button and "extended" format, you will be able to see the residuals for each CORS station used in the solution. Sometimes you can identify problem stations this way.
