Research Associated with Single Gyroscope Dual Ring Platform Inertial Guidance Systems,
Abstract
This article puts forward, and, in conjunction with that, studies mixed inertial and geomagnetic navigation systems composed of single gyroscope dual ring inertial platforms and solid state geomagnetometers. In the article, discussion is made of system construction as well as operating principle.. In depth study is made with regard to system mechanical lay out. In conjunction with this, analyses are completed of system accuracy with a view toward cruise missile flight status. Combined inertial/geomagnetic navigation systems are capable of supplying navigation end guidance information which is the same as that associated with inertial guidance systems. They are not only capable of providing longitude and latitude. They are, moreover, able to supply such information as surface (illegible) as well as attitude angles, and so on. Due to the fact that inertial platforms only make use of one gyroscope and two accelerometers and there is also no bearing stability circuitry, therefore, the structure is simple. Manufacture is easy, and volumes are small. Costs are low. Another obvious advantage associated with the systems in question is that there is no need to carry out azimuth alignment. Preparation times are very, very much shortened.
