PRINCIPLES OF CELESTIAL NAVIGATION MANUAL OF NAVIGATION

In principle then, one should be able to perform celestial navigation using gyroscopes as self-contained stars.The Admiralty Manual of Navigation, Vol 1 The Principles of Navigation provides authoritative guidance on the fundamental principles of marine navigation. This angular orientation is analogous to the fixed line of sight to a star. Solar System12 Celestial Navigation 12.1 INTRODUCTION This chapter discusses the principles of celestial navigation, and in particular, high-precision stellar-inertial.In the absence of torque, a gyroscope's spin axis will maintain a fixed angular orientation in space. 20, Series of 2015 (Curriculum Mapping for BSMT) COMPETENCE KNOWLEDGE, UNDERSTANDING AND PROFICIENCY TOPICS/ PERFORMANCE APPROX HOURS Plan and conduct a passage and Celestial Navigation 1.

As such, the orientation of their gyro spin axes remain fixed in inertial space. These mechanizations lead to concepts unfamiliar to many navigators familiar with celestial navigation.Electrostatic gyroscope (ESG) inertial navigation systems are unique in that they are normally operated untorqued. This results in the gyroscope becoming just an angular rate sensor, and the only measure of true angular orientation rests within the system computer. In the case of strapdown inertial autonavigators, the gyroscopes are torqued to follow the host vehicle angular rates. Ideally these torques are of just the right magnitude to cause the stable platform on which the gyros are mounted to stay locally level.

N., 'SIMILARITIES BETWEEN CLASSICAL CELESTIAL NAVIGATION AND ELECTROSTATIC GYRO NAVIGATION', NAVIGATION, Journal of The Institute of Navigation, Vol. The paper will be based on straightforward physical principles and the concepts presented without resorting to mathematical development.NAVIGATION, Journal of the Institute of Navigation, Volume 26, Number 3Schmidt, J. This will provide the basis for relating angle readout errors and drift rate to their counterparts in celestial navigation.The buzz words used in inertial navigation, such as Schuler tuning and Kalman filtering, will be related to concepts familiar to celestial navigators. This paper will develop this similarity to the point where one familiar with celestial navigation will be able to understand the alinement problem and the fundamental error sources of ESG inertial systems.A specific type of ESG employed at Rockwell International in both gimbaled and strapdown systems will be discussed.
