Publisher Summary This chapter provides an overview of Doppler positioning method which is used to determine accurately the satellite's position and orbit. After several years of work at the Applied Physics Laboratory (APL) of Johns Hopkins University, a prototype satellite was developed and launched, and satellite navigation was born.

Aircraft Navigation by Satellite [PDF]
Journal of Navigation, 1963 Aircraft navigation using doppler and orbital information transmitted from a satellite is shown to be feasible, at least in a limited sense, using the least squares, differential correction method of computation. If sufficiently accurate velocity information can be provided, this approach could yield positions for long-range aircraft that are an order ...

Navigation at sea by satellite
Journal of Geophysical Research, 1966An AN/SRN-9 integral Doppler equipment, developed by the Applied Physics Laboratory of the Johns Hopkins University to give a ship's position at sea when used with navigation satellites, was used on Robert D. Conrad for 9 months in the Atlantic, Pacific, and Indian oceans.

SATELLITE CELESTIAL NAVIGATION [PDF]
, 1967 Abstract : Satellite range and location data can be used to determine the location of an observer. This report discusses how the above may be done by using conventional celestial navigation methods. In lieu of sighting with a marine sextant or a bubble octant to obtain an observed altitude (Ho), a receiver and a phase-measuring technique can be used to

Satellite Navigation and Asia [PDF]
, 2012 Bartholomaeus Pitiscus (1561–1613) was a Polish theologian who first coined the term ‘trigonometry’ which is a branch of mathematics that deals with the relationship between the angles and sides of triangles. This aspect of geometry is of wide-ranging utility to various fields of science and technology.

This chapter describes the Global Navigation Satellite Systems (GNSS) used for positioning and navigation applications. Although a satellite navigation system is very complex, it is common to speak of a “satellite navigation system sensor” when referring to the tools that an end user needs in order to exploit the functionalities of a satellite ...

The Navigation of a Communication Satellite
Journal of Navigation, 1963The navigational aspects of the requirements for a medium altitude satellite communication system are discussed. Twelve satellites have to be injected into a circular equatorial orbit with very great precision. It is not practicable to navigate the launching vehicle accurately enough to obtain the correct orbit at first injection and the satellite ...
