6. the INTELSAT 17 Satellite
TWO COMMUNICATIONS SATELLITES READY FOR LAUNCH Arianespace will orbit two communications satellite on its fifth launch of the year: INTELSAT 17 for the international satellite operator Intelsat, and HYLAS 1 for the European operator Avanti Communications. The choice of Arianespace by 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. Arianespace and Intelsat have built up a long-standing relationship based on mutual trust. Since 1983, Arianespace has launched 48 satellites for Intelsat. Positioned at 66 degrees East, INTELSAT 17 will deliver a wide range of communication services for Europe, the Middle East, Russia and Asia. Built by Space Systems/Loral of the United States, this powerful satellite will weigh 5,540 kg at launch. It will also enable Intelsat to expand its successful Asian video distrubution neighborhood. INTELSAT 17 will replace INTELSAT 702. HYLAS 1 is Avanti Communications’ first satellite. A new European satellite operator, Avanti Communications also chose Arianespace to orbit its HYLAS 2 satellite, scheduled for launch in the first half of 2012. HYLAS 1 was built by an industrial consortium formed by EADS Astrium and the Indian Space Research Organisation (ISRO), using a I-2K platform. Fitted with Ka-band and Ku-band transponders, the satellite will be positioned at 33.5 degrees West, and will be the first European satellite to offer high-speed broadband services across all of Europe. -

ESPA Ring Datasheet
PAYLOAD ADAPTERS | ESPA ESPA THE EVOLVED SECONDARY PAYLOAD ADAPTER ESPA mounts to the standard NSSL (formerly EELV) interface bolt pattern (Atlas V, Falcon 9, Delta IV, OmegA, Vulcan, Courtesy of Lockheed Martin New Glenn) and is a drop-in component in the launch stack. Small payloads mount to ESPA ports featuring either a Ø15-inch bolt circle with 24 fasteners or a 4-point mount with pads at each corner of a 15-inch square; both of these interfaces have become small satellite standards. ESPA is qualified to carry 567 lbs (257 kg), and a Heavy interface Courtesy of NASA (with Ø5/16” fastener hardware) has been introduced with a capacity of 991 lbs (450 kg). All small satellite mass capabilities require the center of gravity (CG) to be within 20 inches (50.8 cm) of the ESPA port surface. Alternative configurations can be accommodated. ESPA GRANDE ESPA Grande is a more capable version of ESPA with Ø24-inch ports; the ring height is typically 42 inches. The Ø24-inch port has been qualified by test to Courtesy of ORBCOMM & Sierra Nevada Corp. carry small satellites up to 1543 lb (700 kg). ESPA ESPA IS ADAPTABLE TO UNIQUE MISSION REQUIREMENTS • The Air Force’s STP-1 mission delivered multiple small satellites on an Atlas V. • NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS): ESPA was the spacecraft hub for the LCROSS shepherding satellite in 2009. • ORBCOMM Generation 2 (OG2) launched stacks of two and three ESPA Grandes on two different Falcon 9 missions and in total deployed 17 satellites. -
Hi-Rel Solutions for Space Launch Vehicles a Single Network for All
© Airbus Safran Launchers 2016 © A Single Network for All Data Traffic Hi-Rel Solutions for Space Launch Vehicles www.tttech.com/space We are delighted that our network solution based on Deterministic Ethernet is providing a very powerful platform “ simplifying the electronic architectures of launch vehicles worldwide! Georg Kopetz, Member of the Executive Board, TTTech Computertechnik AG ” Over the last 25 years, space launch vehicle designs have utilized several different solutions for their on-board data handling. For the safety-critical command and control data, the very robust MIL-1553 bus served as a standard solution, originally designed as a military avionic data bus. For redundancy purposes, this widespread standard enforces two MIL-1553 buses running in parallel. This fact creates the first challenge, namely managing redundant fieldbuses in software and in parallel separate channels for additional data, e.g. telemetry. The second challenge arises from increasing data rates: MIL-1553 is limited to 1 Mbit/s, while there actually is both a need for higher control data rates and an interest in new types of sensors like video cameras. Adding more field buses would be possible, but would increase both weight and software complexity as well as qualification efforts. Finally, despite the need for higher bandwidth and a simplified network, no system cost increase can be tolerated, as in recent years the market for launch vehicles has become extremely competitive. This has led launch vehicle manufacturers worldwide to look for automotive or industrial solutions in order to reduce the cost of the electronics used throughout their vehicles. © Airbus Safran Launchers 2015 After several years of research funded by the ► French space agency (CNES) and afterwards by PROJECT ▼ the European Space Agency (ESA), architectures Launcher avionics A GLANCE AT based on TTEthernet are considered a great fit ► CHALLENGE for launch vehicles. -
Atlas V Cutaway Poster
ATLAS V Since 2002, Atlas V rockets have delivered vital national security, science and exploration, and commercial missions for customers across the globe including the U.S. Air Force, the National Reconnaissance Oice and NASA. 225 ft The spacecraft is encapsulated in either a 5-m (17.8-ft) or a 4-m (13.8-ft) diameter payload fairing (PLF). The 4-m-diameter PLF is a bisector (two-piece shell) fairing consisting of aluminum skin/stringer construction with vertical split-line longerons. The Atlas V 400 series oers three payload fairing options: the large (LPF, shown at left), the extended (EPF) and the extra extended (XPF). The 5-m PLF is a sandwich composite structure made with a vented aluminum-honeycomb core and graphite-epoxy face sheets. The bisector (two-piece shell) PLF encapsulates both the Centaur upper stage and the spacecraft, which separates using a debris-free pyrotechnic actuating 200 ft system. Payload clearance and vehicle structural stability are enhanced by the all-aluminum forward load reactor (FLR), which centers the PLF around the Centaur upper stage and shares payload shear loading. The Atlas V 500 series oers 1 three payload fairing options: the short (shown at left), medium 18 and long. 1 1 The Centaur upper stage is 3.1 m (10 ft) in diameter and 12.7 m (41.6 ft) long. Its propellant tanks are constructed of pressure-stabilized, corrosion-resistant stainless steel. Centaur is a liquid hydrogen/liquid oxygen-fueled vehicle. It uses a single RL10 engine producing 99.2 kN (22,300 lbf) of thrust. -
Launcherone Success Opens New Space Access Gateway Guy Norris January 22, 2021
1/22/21 7:05 1/6 LauncherOne Success Opens New Space Access Gateway Guy Norris January 22, 2021 With San Nicolas Island far below, LauncherOne headed for polar orbit. Credit: Virgin Orbit Virgin Orbit had barely tweeted news of the successful Jan. 17 space debut of its LauncherOne vehicle on social media when new launch contracts began arriving in the company’s email inbox. A testament to the pent-up market demand for small-satellite launch capability, the speedy reaction to the long-awaited demonstration of the new space-access vehicle paves the way for multiple follow-on Virgin Orbit missions by year-end and a potential doubling of the rate in 2022. First successful privately developed air-launched, liquid-fueled rocket Payloads deployed for NASA’s Venture Class Launch Services program The glitch-free !ight of LauncherOne on its second demonstration test was a critical and much-welcomed milestone for the Long Beach, California-based company. Coming almost nine years a"er the air-launch concept was #rst unveiled by Virgin founder Richard Branson, and six years a"er the start of full-scale development, the !ight followed last May’s #rst demonstration mission, which ended abruptly when the rocket motor shut o$ a"er just 4 sec. 1/22/21 7:05 2/6 A"er an exhaustive analysis and modi#cations to beef up the oxidizer feed line at the heart of the #rst !ight failure, the path to the Launch Demo 2 test was then delayed until January 2021 by the COVID-19 pandemic. With the LauncherOne system now proven, design changes veri#ed and the #rst 10 small satellites placed in orbit, Virgin Orbit is already focusing on the next steps to ramp up its production and launch-cadence capabilities.
