This week has seen deployments from the ISS, a Minotaur-1 and a Dnepr of an estimated 34 satellites carrying amateur radio payloads along with a number of commercial and research satellites.
After a launch the North American Aerospace Defence Command (NORAD) issue the Keplerian Two Line Element Set which can be used to determine the position and velocity of the associated satellite. CelesTrak make this information available and the file for launches in the past 30 days is available here.
After a new launch this file will list the ID’s of the objects that NORAD have detected. These objects can be parts of the rocket body as well as the satellites. The challenge in the days after launch is to work out which object ID’s correspond to which satellites.
On the AMSAT Bulletin Board (AMSAT-BB) Nico Janssen PA0DLO has posted an overview of the presently known IDs for the satellites that were launched between November 19-21.
