National Geodetic Satellite Program, Part II: Evaluation

Abstract

The National Geodetic Satellite Program (NGSP) was evaluated to see if the program objectives were actually met. An inspection of the results shows that the general objectives were met. It is concluded that the specific results of the NGSP were too generally stated to allow one to tell whether they were met or were unobtainable. Analysis of methods and results shows that the standard deviations assigned to the results are indications of precision, not accuracy, and cannot be used to rank the various sets of coordinates in order of accuracy.
