They were all deployed on the same launch and if they're all the same size and mass, they won't drift too far apart.
It seems these are more a proof of concept than an operational satellite system.

N2yo shows them, they are really close all in the same orbit like a train. What are they doing with them so close together? -------- Original message --------From: Paul Stoetzer n8hm@arrl.net Date: 3/13/18 5:04 PM (GMT-05:00) To: Joe N3XLS n3xls@yahoo.com Cc: radiomb radiomb@bellsouth.net, Amsat BB amsat-bb@amsat.org Subject: Re: [amsat-bb] FCC and Satellite Size The denied application was for transmissions in the 137 MHz Space Operations Service band.
The orbits are 505 km x 490 km, inclined 97.55 degrees. They are cataloged by Space-Track (see objects 43139 - 43142), indicating at least the ability to track them at some points.

Are these things in a safe orbit? What frequencies do they use? I would hate for one if these .25U objects to hit one of our sats and completely wipe us out. It seems from the two articles i read on this incident a bunch of people messed up. Including swarm not understanding the situation. -------- Original message --------From: radiomb radiomb@bellsouth.net Date: 3/13/18 3:51 PM (GMT-05:00) To: Amsat BB amsat-bb@amsat.org Subject: [amsat-bb] FCC and Satellite Size Just saw this article. The FCC is the controlling agency for the size of a satellite? Not NASA or another agency of the government? Guess that is part of the process that AMSAT has to go thru to get a bird approved. Don't launch these tiny satellites, the FCC said. They're apparently in space anyway
