Vulcan Centaur
VULCAN CENTAUR The Vulcan Centaur rocket design leverages the flight-proven success of the Delta IV and Atlas V launch vehicles while introducing new technologies and innovative features to ensure a reliable and aordable space launch service. Vulcan Centaur will service a diverse range of markets including 225 ft commercial, civil, science, cargo and national security space customers. 1 The spacecraft is encapsulated in a 5.4-m- (17.7-ft-) diameter payload fairing (PLF), a sandwich composite structure made with a vented aluminum-honeycomb core and graphite-epoxy face sheets. The bisector (two-piece shell) PLF encapsulates the spacecraft. The payload attach fitting (PAF) is a similar sandwich composite structure creating the mating interface from spacecraft to second stage. The PLF separates using a debris-free horizontal and vertical separation system with 2 200 ft spring packs and frangible joint assembly. The payload fairing is available in the 15.5-m (51-ft) standard and 21.3-m (70-ft) 1 long configurations. The Centaur upper stage is 5.4 m (17.7 ft) in diameter and 3 11.7 m (38.5 ft) long with a 120,000-lb propellant capacity. Its propellant tanks are constructed of pressure-stabilized, corrosion-resistant stainless steel. Centaur is a liquid hydrogen/liquid oxygen-fueled vehicle, with two RL10C 4 engines. The Vulcan Centaur Heavy vehicle, flies the upgraded 2 Centaur using RL10CX engines with nozzle extensions. The 5 175 ft cryogenic tanks are insulated with spray-on foam insulation (SOFI) to manage boil o of cryogens during flight. An aft equipment shelf provides the structural mountings for vehicle electronics. -

Thenkabail Received: 23 May 2017; Accepted: 12 July 2017; Published: 14 July 2017 Abstract: In the present paper, we describe the design, execution, and the results of an outdoor experimental campaign involving the Engineering Model of the first of the two Argentinean L-band Synthetic Aperture Radars (SARs) of the Satélite Argentino de Observación con Microondas (SAOCOM) mission, SAOCOM-1A. The experiment’s main objectives were to test the end-to-end SAR operation and to assess the instrument amplitude and phase stability as well as the far-field antenna pattern, through the illumination of a moving target placed several kilometers away from the SAR. The campaign was carried out in Bariloche, Argentina, during June 2016. The experiment was successful, demonstrating an end-to-end readiness of the SAOCOM-SAR functionality in realistic conditions. The results showed an excellent SAR signal quality in terms of amplitude and phase stability. Keywords: SAR; pre-flight testing; SAR performance 1. Introduction The forthcoming Argentinean mission Satélite Argentino de Observación con Microondas (SAOCOM) [1] is constituted by two identical Low-Earth-Orbit (LEO) satellites, SAOCOM-1A and -1B, carrying as the main payload an L-band Synthetic Aperture Radar (SAR). -

Ariane-DP GB VA209 ASTRA 2F & GSAT-10.Indd
A DUAL LAUNCH FOR DIRECT BROADCAST AND COMMUNICATIONS SERVICES Arianespace will orbit two satellites on its fifth Ariane 5 launch of the year: ASTRA 2F, which mainly provides direct-to-home (DTH) broadcast services for the Luxembourg-based operator SES, and the GSAT-10 communications satellite for the Indian Space Research Organization, ISRO. The choice of Arianespace by the world’s leading space communications operators and manufacturers is clear international recognition of the company’s excellence in launch services. Based on its proven reliability and availability, Arianespace continues to confirm its position as the world’s benchmark launch system. Ariane 5 is the only commercial satellite launcher now on the market capable of simultaneously launching two payloads and handling a complete range of missions, from launches of commercial satellites into geostationary orbit, to dedicated launches into special orbits. Arianespace and SES have developed an exceptional relationship of mutual trust over more than 20 years. ASTRA 2F will be the 36th satellite from the SES group (Euronext Paris and Luxembourg Bourse: SESG) to use an Ariane launcher. SES operates the leading direct-to-home (DTH) TV broadcast system in Europe, based on its Astra satellites, serving more than 135 million households via DTH and cable networks. Built by Astrium using a Eurostar E3000 platform, ASTRA 2F will weigh 6,000 kg at launch. Fitted with active Ku- and Ka-band transponders, ASTRA 2F will be positioned at 28.2 degrees East. It will deliver new-generation DTH TV broadcast services to Europe, the Middle East and Africa, and offers a design life of about 15 years. -

GB-ASTRA 3B-Comsatbw-21Mai V
A BOOST FOR SPACE COMMUNICATIONS SATELLITES For its first launch of the year, Arianespace will orbit two communications satellites: ASTRA 3B for the Luxembourg-based operator SES ASTRA, and COMSATBw-2 for Astrium as part of a contract with the German Ministry of Defense. The choice of Arianespace by leading space communications operators and manufacturers is clear international recognition of the company’s excellence in launch services. Because of its reliability and availability, the Arianespace launch system continues to set the global standard. Ariane 5 is the only commercial satellite launcher now on the market capable of simultaneously launching two payloads. Over the last two decades, Arianespace and SES have developed an exceptional relationship. ASTRA 3B will be the 33rd satellite from the SES group (Euronext Paris and Luxembourg Bourse: SESG) to have chosen the European launcher. SES ASTRA operates the leading direct-to-home TV broadcast system in Europe, serving more than 125 million households via DTH and cable networks. ASTRA 3B was built by Astrium using a Eurostar E 3000 platform, and will weigh approximately 5,500 kg at launch. Fitted with 60 active Ku-band transponders and four Ka-band transponders, ASTRA 3B will be positioned at 23.5 degrees East. It will deliver high-power broadcast services across all of Europe, and offers a design life of 15 years. Astrium chose Arianespace for the launch of two military communications satellites, COMSATBw-1 and COMSATBw-2, as part of a satellite communications system supplied to the German Ministry of Defense. The first satellite in this family, COMSATBw-1, was launched by Arianespace in October 2009. -
Synthetic Aperture Radar
Synthetic Aperture Radar Subjects: Information Technology & Data Management Submitted by: Sung Wook Paek Definition SAR constellations Table of Contents [Hide] 1. Introduction Space-based radar observation has growing potentials for monitoring the global biospheric diversity subject to anthropogenic drivers at geological scales [1]. The performance of radar is less affected by weather and sunlight conditions than that of optical sensors. Satellites with onboard sensors can provide comprehensive coverage of remote areas or vast regions that may be too costly for unmanned aerial vehicles (UAVs) or ground-based platforms, provided that all platforms provide congruent results via calibrations [2][3][4]. Therefore, it was Seasat, the first satellite dedicated to remote sensing of the Earth’s oceans, that carried the first synthetic aperture radar (SAR) and other radar instruments operable in space. Despite these advantages, miniaturization of radar-carrying satellites was rather slow compared to satellites carrying optical devices due to the lack of commercial-off-the-shelf (COTS) components as well as challenging design requirements for the satellite platform [5][6]. Representative use cases of space-based radar include altimetry, sounding, scatterometry, and so forth in the studies of land, cryosphere, and oceans. Biospheric monitoring is another useful application because radar has high sensitivity in detecting surface changes in a target area and discriminating mobile targets against a background [7]. This paper will consider mainly SAR because of its three-dimensional mapping capability through interferometry. The heritage of Seasat has influenced many of later SAR missions for decades, as listed in Table 1 [8][9][10][11][12][13]; for instance, Shuttle Image Radar (SIR) missions used spare parts of the previous Seasat mission onboard Space Shuttles to test SAR image applications in land use, geology, hydrology, and forestry [14][15]. -
