Abstract

The paper discusses the range of applications for interferometric fiber optic gyroscopes IFOGs in space inertial reference units (IRUs) with an emphasis on satellite usage. The requirements for space IRUs are discussed along with the corresponding features that give IFOGs a singular advantage for many space IRU applications. Development of Honeywell's high performance closed-loop IFOG IRU product is described. Radiation tolerance is a key challenge in many space applications. Accordingly, another possibility for achieving high radiation tolerance using a depolarized IFOG (D-IFOG) is given. Test results for the high performance IFOG for space IRUs is presented as well as open-loop D-IFOG test results.
