A short remark on the terminology is given to avoid misinterpretation. “Satellite-based navigation” means navigation based on satellites, i.e., using signals transmitted by satellites. Quite often, this full nomenclature is shortened to the expression “satellite navigation”.

IETE Journal of Research, 1973
In this review paper the basic requirements and configuration of a typical Satellite Navigation System are outlined. Various techniques such as measurement of angle, range and range rate for position fixing applications are discussed in detail. The orbits employed and the frequency ranges appropriate to each technique are considered.

Navigation Satellite Constellations and Navigation Signals
2021Ground-based radio navigation had been used for more than half a century before the first GPS satellite was launched in the late 1970s. Many radio navigation systems have been developed and put into use since the early of 20th century, including Telefunken Kompass Sender (radio direction finder), Decca (Decca Navigator System), (VOR) VHF ...

Navigation is a main challenge for the operation of an autonomous satellite. This paper deals with the problem of pose estimation for real-time vision based navigation system. Presented method is able to estimate the target pose with high accuracy and does not require any landmark on the object. The results of numerical simulation were presented.

SATELLITE CELESTIAL NAVIGATION
1967Abstract : 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

This chapter begins with a brief overview of four global satellite systems for navigation and positioning, GPS, GLONASS, Beidou and Galileo (under development), and point out the differences between them. We have a cursory look at two regional navigation systems, the Indian NAVIC, and the Japanese QZSS.

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 ...
