i am thinking about an affordable way to build/buy a gradiometer system, that is light enough, to attach it to a drone. like
but low budget. :)
a gradiometer uses two (or more) magnetometers, as far is i know. the big planes use
Scintrex CS-3 seems to be a popular magnetometer for this. i found that the Scintrex
produces a lighter one, the CS-3L (1,8kg/3.96 lbs).
but maybe there is an inexpensive way to built a gradiometer?
an arduino based solution would be perfect. but i found none.
Maybe someone can help out here? Thank in advance!
regards, Joe :)
Have you had any luck since your post in April? Please email me if you'd like to discuss further, firstname.lastname@example.org
Affordable? The CS-VL's cost US$20k each, for a gradiometer set up you will need two of them.
