The project aimed to update several Standard Survey Marks (SSMs) which are part of the National GNSS Campaign Archive (NGCA) network. The raw receiver files were adjusted using the method of Least Squares and compared with the existing coordinates which were captured using GNSS over 25 years ago. Differences in ellipsoidal distance was 0.01m maximal. The differences in ellipsoidal height were 0.077m maximal.
