Preliminary proposal to build a magnetic cancellation system for satellite magnetic tests in Venezuela

A very preliminary proposal to make up a system that cancels the magnetic eld of Earth for executing satellite tests in Venezuela is made. Firstly, it reviewed general status considering electrical currents and possible domains structure equipment reviewed. After checking some cancellation systems, concluded an optimal option be selected Merritt 4-coil because offers good uniformity field large relative volume. considerations taking into account usual size small satellite, coils should around 32 meters. Finally, about movement Earth’s poles are taken account.
