The work performed by individual contributors to the National Geodetic Satellite Program is presented. The purpose of the organization, the instruments used in obtaining the data, a description of the data itself, the theory used in processing the data, and evaluation of the results are detailed for the participating organizations.
Background for the National Geodetic Satellite Program (NGSP) is presented. An historical summary of the program and its technical structure is given. The technical structure of the program is described in enough detail that the reader can relate the work of the individual contributors to each other and to the NGSP.
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.
