Low earth orbit (LEO) satellite systems gained considerable interest in the past decade and were expected to be instrumental in future telecommunications systems. Nevertheless, the first two LEO satellite networks that are currently in operation have not come to fruition on account of the limited spectrum of services that they provide. In this context, future LEO satellite networks will be gear...

With the application of different kinds of satellites, the satellite network will be one heterogeneous and complex system, then the satellite network management is more difficult and the classical network management architecture cannot be applied to the satellite network directly. Aimed at the new features of the satellite network, a hierarchy network management architecture is proposed and a n...

As a service to the satellite operator community, the Center for Space Standards & Innovation (CSSI) offers SOCRATES—Satellite Orbital Conjunction Reports Assessing Threatening Encounters in Space. CSSI runs a list of all satellite payloads on orbit against a list of all objects on orbit using the catalog of all unclassified NORAD two-line element sets (TLEs) to look for satellite conjunctions ...

Current trend in telecommunications is “broadband” and “ubiquitous.” To achieve this goal, satellite communications systems are expected to play an important role in cooperation with terrestrial communications systems. Along with the advancement of optical fiber transmission systems, the role of satellite communications was dramatically changed from long distance transmission to various applica...

this paper focuses upon the development of an efficient method for conceptual design optimization of a satellite. there are many option for a satellite subsystems that could be choice, as acceptable solution to implement of a space system mission. every option should be assessment based on the different criteria such as cost, mass, reliability and technology contraint (complexity). in this rese...

Frequencies above 10 GHz are of primary importance in current satellite systems. In this paper, an analytical model is presented for the prediction of the adjacent satellite interference, cross-polarization and ice depolarization effects on channel capacity statistics of a dual polarized satellite link. As source of the aggravation of the adjacent satellite interference is considered here the p...

Remote sensing satellite data are vast, various, time sensitive and with wide users. How to delivery satellite data and products to users effectively is an important problem facing satellite department. Blueprint has been widely applied in improving service process. It’s a useful method to optimize allocation of resources and improve service quality. This article analyzes the service process of...
