In the densest traffic lanes, it can be difficult from orbit to distinguish individual ships, and this will be even more challenging if all vessels are mandated to carry the system. Also, in an ideal world, AIS needs to be used alongside other technologies. Criminals will be tempted, for example, to disable their ship's AIS and conduct their activities in weather that impedes air reconnaissance. But if an AIS receiver is mounted on a satellite that also has radar, it will be possible to detect this ship through cloudy skies, day or night. The ship's owners will then have to explain why their AIS is not switched on.
