In 1979, SFIM began work on strapdown inertial systems using two axis dry tuned gyros DTG. Since the first feasibility developments SFIM has worked on a large number of applications, the most important being for tactical missiles. All our current developments are based on the same concepts - mass unbalanced gyros M.U.G. - fully digitized electronics - leading to a system family in which the cost and volume requirements are the essential points. The following paper describes the basic ideas, some examples of utilization and the test results obtained on some functional models and prototypes by SFIM and essentially by LRBA.
