North Korea Unha-3 launch

By: RocketGirl
As you know, North Korea is once again planning to launch a satellite. This is pretty interesting for me because that means I get to analyze the launch with STK! That’s exactly what we’ve been doing over the past couple of weeks here at AGI and some of you may have already seen the results on the news or places like YouTube. So how did we do it? We took publically available, open source information from all over the Internet and crafted our scenario. We started with the launch vehicle, the Unha-3, which Wikipedia came in pretty handy for helping us figure out the capabilities of the vehicle. Once we had the vehicle information, we found the trajectory information, including the launch site and the published NOTAM areas provided to the International Maritime Organization, which indicated where the stages are to fall. Finally we found the reports of the intended orbit being a polar orbit. That was enough information for us to use STK to propagate out the first two stages (falling in the proper zones), and the third stage with the satellite heading into a polar orbit.
