Development of Superconducting Technology for Inertial Guidance, Gravity Survey and Fundamental Gravity Experiments.
Abstract
The principles and test results of the superconducting inertial instruments, developed under Air Force contract F19628-87-K-0053, are reported. An improved model of Superconducting Six-axis Accelerometer (SSA-1b) was constructed and operated in both open- and closed-loop (force rebalance) mode. The device has intrinsic noise levels of 10-11 ms-1 Hz-1 and 10-9 rad s-2 hz-2 for the linear and angular acceleration, respectively, and has an open-loop bandwidth of 10 Hz. An ac-driven Superconducting Gravity Gradiometer (SAGG), capable of withstanding hostile moving-base environments, has also been tested under the contract. A three-axis Superconducting Gravity Gradiometer (SGG-11b), developed with NASA support, was used to carry out a precision laboratory test of the gravitational inverse square law under the Air Force contract.
