Copenhagen Suborbitals: The Sapphire guided rocket

Copenhagen Suborbitals posted this video today. It gives a description of the guidance and control system of Copenhagen Suborbitals Sapphire rocket.

The latest CS newsletter also included this item about the Sapphire rocket:

The entire crew of Copenhagen Suborbitals are working hard these days. Summer is coming and in a short time we will attempt to launch our first actively guided rocket “Sapphire”. Sapphire is a test vehicle. It’s only purpose is to verify that our guidance software and control systems work.

As mentioned before the Sapphire rocket is not built to reach space – but will give us invaluable information on active guidance and how to control a rocket in flight. We will use the test results to evaluate and upscale the guidance system so it can be used to guide our bigger rockets that are already in production.

The launch window for Sappire will be announced very shortly. As always we will provide a live and commented video feed of the launch. While you wait we have compiled this second video where Lead Guidance Officer Flemming Nyboe explains how Sapphire’s guidance system works.

Update: Kristian von Bengtson writes more about their plans for Sapphire: Full Time Preparations for Launching the Sapphire – and Happy Hour at Copenhagen Suborbitals – Wired Science/Wired.com.
