| Summary: | In order to avoid the ambiguity of the application of
the Triangulation Method (multi-spacecraft timing method) to
two-dimensional structures, another version of this method,
the Multiple Triangulation Analysis (MTA) is used, to calculate the
velocities of these structures based on 4-point measurements. We
describe the principle of MTA and apply this approach to a real
event observed by the Cluster constellation on 2 October 2003.
The resulting velocity of the 2-D structure agrees with the ones
obtained by some other methods fairly well. So we believe that
MTA is a reliable version of the Triangulation Method for 2-D
structures, and thus provides us a new way to describe their
motion. |
