In modern communication systems, satellite networks play a crucial role in providing global coverage and high-speed data transmission. Traditional network simulation tools face challenges such as high complexity, poor scalability, and inadequate performance, making them unsuitable for simulating satellite networks. To gain a better understanding of satellite network performance and operation, this paper introduces a Docker-based satellite network simulation platform. This platform simulates satellite constellation link establishment rules and uses Docker to construct satellite network topologies, automating snapshot switching, link simulation, satellite communication, and other functions. The platform provides an experimental environment for the design, optimization, and performance evaluation of satellite communication systems, aiding researchers in gaining deeper insights into the operation and performance characteristics of satellite networks.

“…Dynamics on climate changes, remote sensing applications for oceans, different astronomic observations, ion density records in the ionosphere, and very specific humanitarian applications related to search and rescue services are some of activities carried out by LEO satellites, activities which are too difficult or impossible to be implemented on Earth. For these activities within satellite structures, the instruments or devices for the appropriate application or mission are installed (Zee and Stibrany, 2002;Cakaj et al, 2010a). Usually, LEO satellites dedicated for scientific purposes or remote sensing applications are accommodated in specifically designed orbits, known as Sun synchronized.…”

Communications-integrated satellite-terrestrial networks used for global broadband services have gained a high degree of interest from scientists and industries worldwide. The most convenient structures for such use are low Earth orbit satellites, since they fly closer to the Earth compared to the other orbits, and consequently provide significantly lower latency, which is essential for reliable and safe communications. Among these efforts is the Starlink satellites constellation, developed and partly deployed by the United States Company SpaceX. The constellation is planned to be organized in three spatial shells, each of them made up of several hundreds of small-dimensioned and light-weighted low Earth orbit specially designed satellites to provide broadband services, intending to offer global Earth coverage through their interoperability, combined also with the ground stations as a part of the satellite-terrestrial integrated network. By October 24, 2020, 893 satellites are situated in orbit of altitudes of 550 km under different inclinations, determining the first Starlink orbital shell. Two next generations are planned to be situated at altitudes of 1,110 and 340 km, to complete the appropriate infrastructure of three Starlink satellite shells, toward a global presence of broadband internet services. These three orbital shells offer different space views seen from the ground station (user) because of their different altitudes, thus in this paper a few parameters which describe the satellite’s behavior considered from the ground station’s (user’s) point of view are compared. These parameters in fact stem from the space orbital parameters and are defined as: horizon plane wideness, slant range, latency, and coverage area. A comparison is given for the three Starlink orbit layers, with identification of appropriate drawbacks and advantages as performance indicators. By the end, these parameters are applied to geometrically interpret and confirm the handover process among satellites. This paper may serve to highlight the new challenges of the satellite-terrestrial integrated network, providing some theoretical analysis and performance comparisons for the satellites in different orbit layers seen from the ground station (user) perspective.

“…To call a rescue service, a man in distress must switch on the "beacon" and after a while the beacon starts transmitting short impulses at least for 24 hours, or until some rescue service arrives. LEO, MEO (Medium Earth Orbit) and GEO (Geostationary) satellites relay the message to a Local User Terminal (LUT) on the Earth [1], which will relay the message to a rescue service. The assistance of the rescue service will be the more effective and cheaper, the more precise and quick is the distress localization.…”

In this paper, a new satellite based search and rescue system is designed. The old one -the COSPAS-SARSAT distress alert detection and distribution system, has been working for 30 years and rescued about 40 thousands of lives world-wide, in spite of low precision of the distress localization and long localization time. In this paper, a new system is designed, whose user terminal can be implemented into a 3G mobile phone, without increasing its size and power, while using a Global Navigation Satellite Systems (GNSS) like GPS, GLONASS or Galileo. The system will offer an exact and quick location service also in areas without the terrestrial mobile network coverage for billions of 3G users.
