An Integrated Optics Strapdown Inertial System Configuration is described. The new concept is based on the passive ring resonator approach now being developed for the Laser Gyro. The measurement of rotation rate and acceleration is accomplished using a common ring resonator where both devices operate in the frequency domain. In addition, a laser accelerometer is described using the interferometer approach and operates in the phase domain. The study is an important first step that may lead to a new Strapdown Inertial System where the accelerometer and gyro are implemented on a single "chip" which would allow the system to be packaged in a very small volume and could possibly lead to a low cost sensitive strapdown system that could be universally used in both military and com-mercial carriers.
