Relativistic Time Transfer for Inter-satellite Links

Relativistic Time Transfer for Inter-satellite Links

Inter-Satellite links (ISLs) will be an important technique for a global navigation satellite system (GNSS) in the future. Based on the principles of general relativity, the time transfer in an ISL is modeled and the algorithm for onboard computation is described. It is found, in general, satellites with circular orbits and identical semi-major axes can benefit inter-satellite time transfer by ...

Analysis of Low Earth Orbit Satellite Networks with Inter-satellite Links

Evaluating TCP Mechanisms for Real-Time Streaming over Satellite Links

Real-time streaming over satellite IP networks is challenging, since satellite links commonly exhibit long propagation delays and increased error rates, which impair TCP performance. In this context, we quantify the effects of satellite links on TCP efficiency and streaming video delivery. We investigate a solution-framework composed by TCP implementations which are expected to perform adequate...

A Probabilistic Study of Inter-Satellite Links Load in Polar Orbit Satellite Constellations

We analyze the load of the inter-satellite links in polar satellite constellations. Starting from simple considerations on the structure of the underlying network topology, we derive the probability of use of diierent families of links, with various hypotheses on the nature of the traac. Our analysis leads to a simple, practical evaluation of the asymptotical link load, which depends on the pos...

Performance evaluation of LEO satellite constellations with inter-satellite links under self-similar and Poisson traffic

lation study for the evaluation in low earth orbit (LEO) ellations, used for the of high-speed networks, is paper. The proposed model end the traffic process at the supporting successfully the f self-similar traffic sources , ach that has been considered an the well-known Poisson, munications. dy for the establishment of s (ISLs) and the design of the ace segments is presented and of the integr...
