The Navigation of Navigation Satellites
Journal of Navigation, 1986The orbits of navigation satellites have to be determined very precisely. The Transit broadcast (predicted) ephemeris, which is computed by the US Navy Astronautics Group, has an estimated orbital positional accuracy of the order of 25 m in each direction.

Satellite-Based Navigation Systems
2012This chapter focuses on various satellite-based navigation systems. The most well-known and widespread system currently used for localization of a radio-receiving terminal is the global positioning system (GPS). All GPS satellites share the same frequency bands, making use of the code division multiple access (CDMA) technique. The transmitted signal on

INTENDED to provide highly accurate three‐dimensional position and velocity and precise time on a continual global basis, the NAVSTAR Global Positioning System (GPS) has been under development by the US Department of Defence since the early 1970's. It is a satellite based radio navigation system which, when it comes into operation in 1988, will consist

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”.

Satellite Navigation Inter-satellite Link Technology
2020Inter-satellite link (or Crosslink) refers to the link between satellites, or the link between spacecraft in a more generalized sense. Its main functions include inter-satellite communication, data transmission, inter-satellite ranging, and inter-satellite TT&C.

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.
