Geoid Measurements by Satellite

July 22, 2010

The European Space Agency has been doing a survey of the worlds gravity field using a satellite, and they’ve produced this world map showing the results.

I’m not a geo-physicist, but it’s interesting to see the blue area just South of India.

A dip like this means that any satellites circling the globe would pass lower over this area. (Perhaps they like the curry?)
