[Archive] Direct charge measurment

Message by Abhijit Sen:
Dear all,
Is it possible to calculate number of electrons and ions absorbed on the surface of spacecraft. This will help in calculating the charge on object directly.

Message by Jean-Charles Mateo-Velez:
you have access to the currents but not to the cumulated charge. This is an interesting idea to cumulate this charge and compare with Gauss theorem for insatnce
