Abstract
Abstract : The methods of Doppler Satellite surveying, as applied to establishing hydrographic shore control, are presented and evaluated. Both methods, point and relative positioning, are defined procedurally with the advantages and disadvantages of each included. The field operations of two Doppler surveys (Monterey and Lake Superior) are reviewed with regard to requirements and procedures. A cost breakdown of the Lake Superior survey illustrates the high cost effectiveness of satellite techniques. The results of four Doppler data reduction programs (DOPPLR, MAGNET, GEODOP V, and MX 1502 translocation) are included and compared. Results of a special survey are included to demonstrate the high accuracy attainable by relative positioning methods. Selected data sets from both Doppler surveys were reduced using GEODOP V and are used to illustrate survey design and planning considerations. An accuracy standard for Doppler established shore control, compatible with both IHO and NOS accuracy standards is proposed. A method for determining station elevation differences is also presented. Originator-supplied keywords include: TRANSIT satellites; hydrographic shore control; hydrography; point positioning; relative positioning; GEODOP V; MAGNET; MX 1502; datum shift; NOS accuracy standards; IHO accuracy standards; translocation.
