Gavity Station

RECOVERED MY 1ST GRAVITY STATION TODAY AND MY BOOKS DO NOT HAVE ANY DEFANITION FOR THESE.

WHAT ARE THEY USED FOR?

That is an interesting question. Having learned that the NASA BM I recovered was possibly used for survey information back in the days when we sent men to the Moon I feel certain that there is an equally scientific answer to this question. Happy BMing!

Knowlege of the Earth's gravity field is a important part of the science of Geodesy and is vital to the ability to accurately determine height systems. Gravity stations were set as reference stations where the local gravity was observed with very specific equipment designed to observe the absolute value of the local acceleration of gravity, much like bench marks provide the local value of heights for other surveys. C&GS stopped setting these marks in the mid-60s. The collection of gravity data has been important to the ability to create a quality modern geoid model such as the recently released GEOID03.

Thanks for replying Dave! Although I'm not a scientist nor an engineer, I do realize how this information could be very important for those in GIS and science fields.

 

I often feel humbled by the work that is performed by those behind the scenes that are never acknowledged for the work that they do that allows me to enjoy modern conveniences and advancements.
