The feasibility of an airborne sounding system should be determined. 

 If such a system is feasible, it should be developed and combined with 

 a suitable navigation system for the rapid surveying of large areas. 



The Hydrographic Office intends to monitor any new instruments 

 developed to ensure that they include features which would facilitate 

 the processing of the results obtained and to test these instruments 

 when developed to determine their accuracy and reliability under 

 survey conditions. RDT&E funds for FY 1962 are being requested to 

 support specific work.
