The space environment provides an assortment of hazards whose ill effects can range from degraded performance up to catastrophic loss of a spacecraft. By April 22, 2014, initial electrical testing and checks of the propulsion system had been completed with nominal results showing that the satellite was charging its batteries and distributing power to all subsystems. Calculating resistors in parallel is precisely the same as the calculations required for inductors in parallel or for capacitors in series. The problem will be fixed in the next few hours," explaining that, "any failure in control of satellite begins with absence of response to commands from Earth, and the low battery could be the problem, but it will be fixed and control will be fully restored.
EgyptSat-2 was designed and built by RSC (Rocket and Space Corporation) Energia and uses a variation of Energia's USP (Universal Satellite Platform) known as 559 GK bus (previously used on the Yamal-100 spacecraft series). The single RD-0110 engine of the final stage then roared to life to boost EgyptSat-2 into orbit. The slowed down spectra emerging from the shielding material is obtained using the Multilayered Shielding Simulation Software (MULASSIS) code. EgyptSat-2 is a hexagonal satellite, equipped with three deployable, fixed solar arrays, together with nickel-hydrogen batteries, and is expected to remain operational for approximately 11 years. The satellite was taking pictures of the planet in the visible and infrared spectrum with panchromatic and multispectral modes. In multispectral mode, the instrument acquires full color images at a resolution of 4 m. Panchromatic images achieve a resolution of 1 m. The optical imager supports various modes of operation including single-scene imaging, route imaging, mapping and stereo imagery acquisition. It is the moment when the satellite, after passing above the place, touches the horizon line and its signs can no longer be captured. MAX and Range - Moment of the satellite's maximum approach. u/GDBarrett. Thanks for helping us catch any problems with articles on DeepDyve. The imaging payload was developed by OAO Peleng and NIRUP Geoinformatsionnye Sistemy in Belarus. وفي مايو 2016، أعلنت شركة ” RSCانيرجيا “ إنها بدأت في إنشاء قمر أخر من خلال التغطية التأمينية للقمر المفقود. The satellite's coverage included total coverage of Egypt's land and maritime territory and their environs.
[19], Insurance payout from the loss largely paid for the manufacture and launch in February 2019 of the EgyptSat-A replacement satellite. The spacecraft has a launch mass of 1050 kg and utilizes a hexagonal satellite body that uses a modular design approach to allow the platform and payload to be manufactured separately … Contact with the spacecraft was lost in 2010, but the mission demonstrated the benefits of the operation of an Earth observation satellite, providing detailed data for digital mapping purposes and various scientific studies. We'll do our best to fix them.

2). Ab April 2015 reagierte Egyptsat 2 jedoch nicht mehr auf Kommandos von der Erde. Thursday at 11:47 AM EST, ROSCOSMOS will be launching a Soyuz-2 with EgyptSat-A on board to conduct earth imagine and observation. The project was handled by RKK Energia based on Korolev on the behalf of Russia, codenamed "E-Star". Data will be transmitted through an X-band communications terminal at a rate of 300-600 Mbits/sec to ground stations located near Cairo in the north of Egypt and Aswan in the south. On the up right side of this picture we have the countdown for the satellite to blunt on the horizon. Most likely, the satellite cannot be restored," a space industry source told the newspaper on June 5, 2015. At T-6 minutes, the booster entered its automated countdown sequence, and about 60 seconds later the “launch key”—an actual, physical key which enables the ordnance systems and permits the launch to go ahead—was inserted under the direction of the Launch Director in the command bunker. At T-10 seconds, the turbopumps on the central core and the four tapering boosters awakened and the engines steadily built up thrust to full power, producing a retraction of the fueling tower and a spectacular, on-time liftoff into the darkened Baikonur sky at 10:20 p.m. local time (12:20 p.m. EDT).
However, Egypt continued working with Yuzhnoye Design Bureau for the next project, until it received a bid from Russia to supply a state-of-the-art "eye in the sky". - Comments and corrections to this article are always welcome for further updates (herb.kramer@gmx.net). The numbers indicate the moment of the event, as well as the azimuth, elevation and altitude of the satellite Der dreiachsenstabilisierte Satellit ist mit CCD-Kameras für sichtbares und infrarotes Licht ausgerüstet die im Entwicklungsbüro Peleng (OAO Peleng) und dem nationalen Zentrum für Informationstechnik- und Quellen (NIRUP) in Minsk entwickelt wurden.

The satellite is jointly built by Egypt's National Authority for Remote Sensing and Space Sciences together with RKK Energiya in Russia. • June 9, 2015: Egypt has lost control of the remote sensing EgyptSat-2 orbital satellite and is considering purchasing Russian satellite images of Earth, the Russian Kommersant daily reports. For a satellite can be observed directly, it is necessary that the sunshine reaches its structure and is reflected into our eyes. EgyptSat-A is a high-resolution Earth observation satellite developed by Russian corporation RKK Energia on behalf of Egypt’s National Authority for Remote Sensing and Space Sciences (NARSS).
Inhaltsverzeichnis Februar 2019 um 16:47 Uhr UTC mit einer Sojus-2-1b-„Fregat“-Trägerrakete vom Raketenstartplatz Baikonur in eine sonnensynchrone Umlaufbahn gebracht.
Meaning that technically, it can be seen, nevertheless other factors can influence its observation, among them the satellite's altitude and size, its coating material and the atmospheric conditions of the local observation. RSC Energia sub-contracted the development of the satellite's imager and its data downlink system to OAO Peleng and NIRUP Geoinformatsionnye Sistemy in Belarus. [13], A new and revolutionary technology had been demonstrated first time, as EgyptSat 2 became the first frameless spacecraft created in Russia and the first satellite created by such technology in the history of Russian cosmonautics. Die Speicherung der elektrischen Energie übernehmen Nickel-Metallhydrid-Akkumulatoren. At length, the second mission was tentatively scheduled for launch in 2013, but this target was postponed several times. Its optical imaging payload will cover the visible and infrared spectral bands, providing a ground resolution of 13.1 feet (four meters) for multispectral imagery and 3.3 feet (one meter) for panchromatic imagery.
EgyptSat 2 (MisrSat 2) ist ein Erdbeobachtungssatellit der ägyptischen Behörde für Fernerkundung und Weltraumwissenschaften (National Authority for Remote Sensing and Space Sciences, NARSS). 1 - Dark sky: it should be night on the observation location Tylka, A. J.; Dietrich, W. F.; Boberg, P. R.; Smith, E. C.; James, H.; Adams, J. The arrays are fixed and do not provide sun-tracking functions.
