 | Two Litton MS-4 Multisensors, S/N 17 and S/N 23 were tested at the Central Inertial Guidance Test Facility, 6585th Test Group, Holloman AFB, New Mexico during the period from November 1973 to June 1975. The purpose of the tests was to collect performance and environmental data on the instruments. The laboratory tests included gyro and accelerometer coefficient determination; drift tests; voltage, frequency and temperature sensitivity tests; and scale factor linearity ... |

|
| Three aspects related to the development of the strapdown micro-navigator (MICRON) system have been investigated. By comparing the present Micro-ElectroStatic Gyro (MESG) drift rate and attitude readout error models with a previously developed mathematical modeling theory, expressions for many of the model coefficients were derived and the corresponding error mechanisms were defined. The equations for the simultaneous calibration of both the MESG drift rate and attitude readout error model coefficients ... |

|
| This report covers the latest phase of the Nutatron angular rate sensor development effort, culminating in the delivery of two prototype sensor and an electronic test set to the U.S. Air Force Central Inertial Guidance Test Facility (CIGTF) at Holloman AFB. The objectives of the Nutatron Program is to lead to angular rate sensor for tactical fighter navigation systems, offering fast reaction from a cold start, low temperature coefficients and ... |

|
| This effort is significant to the Air Force in that an angular rate sensor is being developed that will eventually result in the production of a low-cost, reliable, strapdown inertial system. The results of a ring laser techniques investigation performed by Autonetics Division of North American Rockwell Corporation are presented in this document. The objective of the contract was to demonstrate laser gyro performance suitable for strapdown guidance and navigation ... |

|
| Two techniques, both of which use the Faraday bias effect, were investigated for eliminating or reducing the lock-in effect. One technique, dual FM bias, is a passive scheme which uses two ac bias signals which drive the RLG through the lock-in region in such a manner that lock-in does not occur. Dual FM bias is discussed in Volume I. The second bias technique, servo-linearization, uses an active control technique for ... |

|
| The significance of this research and development program to the Air Force is that a gyro is being developed that does not depend on its accuracy being achieved through ultra-precision fabrication of parts and extensive test and calibration. Hence, the result will be a gyro with stable and repeatable performance under adverse environments, in addition to lower cost and higher reliability. The prime objectives of this follow-on program were the ... |

|
| The Nutatron gyro features an anisometric rotor which responds to torques by exhibiting minute signals at twice the rotor frequency. These signals are used to automatically compensate for the drift producing torques and as a result the Nutatron is a high performance, low cost gyro with fast reaction time. Under previous contracts, the feasibility of the concept was demonstrated and an engineering model was designed, fabricated, and tested. This report ... |

|
| A study was conducted on the circulation of lubricants in the R-4 spin-axis gyro bearing. The flow of lubricant was traced by incorporating 1% anthroquinone dye in the lubricant impregnated in an isolated portion of the sintered nylon retainer and periodically observing the color change of the undyed section as the lubricant was transported. Flow rates were determined for variations in speed, preload, bearing geometry, ambient pressure, lubricant viscosity and ... |

Howard Musoff; MASSACHUSETTS INST OF TECH CAMBRIDGE INSTRUMENTATION LAB
|
| A method is described whereby two half-cycle cosine-modulated radio-frequency carrier waves are used to transfer gyroscope wheel-motor power through the gyroscope damping fluid. This halfcycle modulation method is compared with both full-cycle amplitude modulation and suppressedcarrier modulation methods for transferring power. Also presented are efficiency measurements obtained from a breadboard demodulator using the half-cycle modulation method. (Author) |
