The technology improvement of MEMS now makes them useful for precision INS applications that were previously dominated by FOG’s.
The advancement of technology has always led to previous products and methods becoming outdated or obsolete. Automobiles replacing horses, furnaces replacing fireplaces, and streaming services replacing DVDs are just a few of the countless examples of this. In the navigation industry it is becoming more and more evident that Fiber Optic Gyroscopes (FOG’s) are finding themselves in a similar battle with Micro-Electro Mechanical Systems (MEMS). Paired with Inertial Navigation Systems (INS), MEMS are quickly encroaching on sectors normally dominated by FOG’s. This article explores how this transition between the technologies applies to INS, as well as provide examples of where MEMS would be chosen over FOG’s, and potentially vice versa in certain applications. To support the claims made in this article, benchmarking of two real-time systems was used.
