I found several articles that may be of interest on a website "devoted to analysis of North Korea." The site http://38north.org/ is a program of the US-Korea Institute at SAIS (School of Advanced International Studies, Johns Hopkins University).

The first was published in April, and has as detailed a description and photographs of what was probably the engineering prototype of the satellite that was successfully orbited: http://38north.org/2012/09/nhansen091212/. The second, published shortly before the launch, discusses GeoEye satellite imagery that shows preparations at the launch site: http://38north.org/2012/12/sohae121112/. A third article shows the launch trajectory and has a link to a KMZ file that illustrates approximately the first half-orbit that can be viewed in 3-D with GoogleEarth: http://38north.org/2012/04/tongchang041012/ http://38north.org/2012/04/tongchang041012/.
