I'm solving a regional campaign and have been just using IGS orbits, but I keep running into problems with "too many files" when I run ADDNEQ. This happens even if I generate weekly average position NEQ files with ADDNEQ and then try to ADDNEQ the weekly NEQs for velocity because it apparently still counts each orbit and erp? file used in the daily runs. Do I have to solve for daily orbits and generate a week-long orbit arc? I really don't have the station coverage to do a meaningful orbit solution but I could generate orbit solutions with tight constraints to the IGS a priori orbits and erps if I have to.
