Milli-HRG inertial navigation system
Gyroscopy and Navigation, 2012The Hemispherical Resonator Gyro (HRG) has proven itself to be an ultra-reliable technology for space application with over 18 million operation hours and 100% mission success. Northrop Grumman Navigation Systems Division is developing a terrestrial inertial navigation system (INS) based on the proven space technology that can be used for precision ...

A Generic Inertial Navigation System
2019 International Interdisciplinary PhD Workshop (IIPhDW), 2019In order to control the movement of a vehicle, precise position and movement information is required. This information is usually obtained through a data fusion of different sensors. This paper presents a new approach of a generic fusion filter for integrated navigation systems, which can be integrated for different types of vehicles.

Strapdown inertial navigation system calibration
2017 2nd International Ural Conference on Measurements (UralCon), 2017The paper aims at improving the accuracy of the calibration of strapdown inertial navigation systems (SINS). The calibration is carried out using a 2-axial motion simulator. A new computational method is investigated for the calibration coefficients of the error models of accelerometers and gyroscopes of the strapdown inertial navigation system based ...

Strapped Down Inertial Navigation Systems
Journal of Navigation, 1973The heart of an inertial navigation system is the Inertial Measuring Unit (I.M.U.) as this carries out the fundamental tasks of measuring the vehicle acceleration and providing a spatial reference. The I.M.U. thus determines the system performance and accuracy; it also accounts for about two thirds of the initial cost of the system and is a major ...

Fault tolerant inertial navigation system
Digital Avionics Systems Conference, 1988This paper describes the sensor redundancy management concept employed in a fault tolerant inertial reference system built by Honeywell's Commercial Flight Systems Minneapolis Operation to be flight tested in 1988. vided. No attempt was made to use state of the art packaging.

Inertial navigation system alignment
2004Alignment is the process whereby the orientation of the axes of an inertial navigation system is determined with respect to the reference axis system. The basic concept of aligning an inertial navigation system is quite simple and straight forward. However, there are many complications that make alignment both time consuming and complex.

Damping Gimballess Inertial Navigation Systems
IEEE Transactions on Aerospace and Electronic Systems, 1967The mechanization of a gimballess inertial system for space navigation is considered. An error analysis reveals that the errors contain both sinusoidal and diverging components. Error damping methods are proposed and it is shown that damping can be achieved by using appropriate damping circuits and auxiliary information obtained from devices such as ...

Inertial Navigation System Testing 1967
Journal of Navigation, 1967The Central Inertial Guidance Test Facility (C.I.G.T.F.) at Holloman Air Force base, New Mexico, has the responsibility for testing all aircraft inertial navigational systems, aided and unaided, for Department of Defence applications. From 1963 to the present, ten systems have been evaluated.

A Wellbore Inertial Navigation System
IADC/SPE Drilling Conference, 1983Abstract A prototype wireline tool which includes a downhole inertial platform and a surface computer to spatially map a well is described. The hardware consists of a single-gimballed inertial platform with accelerometers and gyros to obtain three-axis motion information.

Global Navigation Satellite Systems and Inertial Navigation
2011When one would rank the geo-data collection techniques developed the last three decades or so from most significant to least significant, positioning and navigation by means of Global Navigation Satellite Systems (GNSS) would head the list. GNSS enables obtaining precise positioning and timing information anywhere on land, on sea or in the air, day or ...
