SAP). This program will continue its dual role of providing up-to-date 

 harbor charts and of training foreign personnel in hydrographic surveying 

 and techniques of chart construction. The HARSAP coordinator, assigned to 

 the Canal Zone, maintains active interchange with the seven participating 

 Central and South American countries, as well as liaison with several addi- 

 tional Latin American countries, and assists in courses given in hydrographic 

 surveying and chart construction at the Inter-American Geodetic Survey 

 (lAGS) school there. Fourteen nautical charts are presently scheduled for 

 production by the host countries as a result of these surveys. 



Geodetic surveys in support of operations range from the establishment of 

 shore control for coastal surveys to the p>ositioning of OMEGA and other 

 electronic ocean-navigation system shore stations. A new satellite receiver, 

 the AN/PRR-14 Geoceiver, which operates with the Department of Defense 

 geodetic satellite system, represents a major advance in the capability to tie 

 distant isolated points, such as ofTshore islands^ to a common datum. Navy's 

 international tracking network associated with the geodetic satellite is being 

 augmented by the Geoceivers, and all major Navy survey ships are being 

 outfitted with them. 



Navy's oceanographic survey capability has been expanded through the 

 delivery and operational deployment of another ship of the Silas Bent class, 

 the USNS Wilkes (T-AGS 34). This stabilizes the force level assigned to 

 support the ASW program at three ships, two in the Atlantic and one in the 

 Pacific. In addition to geophysical data, these ships collect acoustic and water 

 mass data and perform special sea-floor studies. Over 700 deep oceano- 

 graphic stations and almost 100 acoustic stations were accomplished in 



Navy's Harbor Survey Assistance Program (HARSAP) brings U.S. technology and 

 engineers together with Central and South American surveyors in a joint effort 

 charting foreign ports and harbors.
