 Science with 4 Spacecraft


Waves


Multiple spacecraft observations of wave features provide more information about the wave than a single spacecraft can..

below: a single spacecraft registers a wave as a disturbance, with no indication of the direction (it can also
be hard to identify the wave mode). Compare this with multiple spacecraft measurements (next figure).

below: this figure shows how 3 spacecraft can uniquely identify the direction of a wave on a 2D plane (and we need 4 spacecraft to do the same job in a 3D volume).
