Geodetic location of acoustic ocean-bottom transponders from surface positions



In late 1969, Battelle Memorial Institute-Columbus Laboratories (Battelle-Columbus) was involved in a NASA experiment in the Bahamas, the over-all objective of which was to determine the feasibility of using C-band radar for ship positioning and for establishing marine geodetic control points.

The use of C-band radar for marine measurements is desirable for several reasons: (1) C-band radar can be operated in a ranging mode by measuring distances from ship to satellites and provides a particular advantage in that errors in ship velocity are not as critical as they are with the Doppler satellite technique; (2) several ships already have C-band radar systems on board; and (3) it provides an additional satellite system for geodetic measurements at sea.
