MEMS-based Space Launch Vehicle Guidance System Design Problem

Recently several new worldwide satellite internet projects (American one of Google and SpaceX, British OneWeb and Russian Yaliny) have been started. Each project is based on network of dozens of small satellites.In order to run smoothly broken satellites must be promptly replaced with new ones. Replacing small satellites one by one by dedicated traditional large space launch vehicles will be absurdly expensive. Launching as secondary payload is a low priced option, but preparing the primary payload often leads to huge delays. That is why a lot of start-ups in the world are trying to develop ultralight rocket that could quickly launch into space a satellites weighing from about 1 to 200 kg. One of the difficulties of creating such rocket is to design and build cheap guidance system. Really cheap rocket control system could be based on MEMS-gyroscopes.
This article is dedicated to the MEMS sensor errors, both systema- tic and stochastic, sensor behavior during simulated rocket launch and orbital insertion scattering using this sensor.
