The exploration and investigation of near-Earth outer space (NES) have highlighted attention to potential threats, namely the dangers posed by asteroids and the emergence of techno-genic pollution known as space debris (SD). To address these challenges, an international initiative known as the ISON Optical Observatories Global Network was establish...

https://doi.org/10.51194/INASAN.2023.8.4.002 The International Scientific Optical Network (ISON) is an open international scientific project specializing in observations of near-Earth space objects. It began at the Pulkovo Observatory in 2004, then was continued at the Keldysh Institute of Applied Mathematics of the Russian Academy of Sciences, and...

Международная научная оптическая сеть ИСОН - открытый международный научный проект, специализирующийся на наблюдениях околоземных космических объектов. Он начался в Пулковской обсерватории в 2004 году, затем был продолжен в Институте прикладной математики им. М.В. Келдыша РАН, а с 2019 г. реализуется частной компанией "Малое инновационное предприят...

Studying the long-term dynamical evolution of space debris and the development of optical measurements help us to avoid collision risks caused by these objects. In this work we studied the long-term evolution of space debris orbits, in GEO and MEO regions, under the effect of natural perturbations. The perturbations considered are the Earth’s gravi...

Studying the mechanical properties mismatching of SnSe 2 /ZrS 2 2D materials with Voigt-Reuss-Hill (VRH) schemes promise a novel structure for sensing applications. For the first time, we studied the effect of mechanical mismatching properties of SnSe 2 /ZrS 2 multilayers with VRH schemes on the acoustic wave's propagation through acoustic superlat...

In many cases, we have few optical observations over a short time span, and most of the information generated is too limited to compute a full orbit according to the angles-only method. This study aims to develop a mathematical model to determine the precise orbit from the optical observation data by the least squares method. We have used a set of...

The initiative ISON project started in 2004 with the support of grants. In a broad international cooperation, a full cycle of research on so-called space debris was worked out — setting tasks, wide-angle optical telescopes, software, places for observatories, a population model. And ISON became an incubator of innovative solutions that were impleme...

One of the most valuable regions for telecommunication and space science is the geostationary earth orbit (GEO). On 27 November 2019, Egypt successfully launched its telecommunications satellite TIBA-1 into space. This paper aims to effectively identify and concurrently track this satellite from our Kottamia observatory station, National Research I...

International Scientific Optical Network (ISON) is an open international voluntary project specializing in observations of the near-Earth space objects. Observatories collaborating with ISON provide the global coverage and successfully combine the observations of the space debris and asteroids. The network includes more than 50 telescopes of 27 obs...

Growing the number of space debris has recently become a topic of eminent concern. Therefore, orbital debris removal has become a very grave issue for both of scientific and commercial space management in order to avoid loss any operational satellite. To prevent loss of spacecraft due to debris collision, it is very essential to address the aggrega...

Space debris of millimeter dimensions is almost not detectable by normal methods of observation from Earth. However, particles of such sizes can cause damage to the spacecraft. and even eliminate it. Estimating the status of impurity of near-Earth space mainly based on mathematical models, which are confirmed only for large particles. The millimetr...

The results of single television observations of Perseid meteor shower in 2016 are presented. The Perseid shower occurs from 17 July to 24 August, peaking on or around August 12 every year. In 2016, the peak of the Perseids was Night of Aug 11 to the morning of Aug 12. The meteor video observations in Egypt are carried out at The National Researche...

Now we know that meteors (''shooting stars'') are the light phenomena which appear during the invasion of cosmic particles of small size in the Earth's atmosphere. The most effective way to conduct...

Effect of perturbations due to gravitational potential and drag on ground track of satellites orbits are studded. Components of velocity and position are obtained and the new orbital elements under the effect of perturbations are calculated to determine the latitudes and longitudes of the ground tracks.
