ATLAS V WORLDVIEW-4 MISSION ATLAS V 401 An Atlas V 401 rocket will deliver DigitalGlobe’s WorldView-4 sat- The Atlas V 401 rocket has become the workhorse of the Atlas V fleet, ellite to near sun-synchronous orbit. The (ULA) delivering half of all Atlas V missions to date. In its more than 14 years Atlas V rocket is provided to Commercial Launch of service, the 401 has delivered 19 national security missions, eight Services. Liftoff will occur from Space Launch Complex-3 at Vanden- science and exploration satellites, three commercial flights and two berg Air Force Base, California. resupply missions to the International Space Station. First Launch: Aug. 21, 2002 WorldView-4, a multispectral, high-resolution commercial imaging Launches to date: 32 satellite owned and operated by DigitalGlobe, will help customers around the world see more of our changing planet. The satellite was Performance to GTO: 4,750 kg (10,470 lb) built by Lockheed Martin Space Systems Company and will provide Performance to LEO-Reference: 9,800 kg (21,600 lb) 31-centimeter panchromatic resolution and 1.24-meter multispectral resolution—the same resolution offered by the WorldView-3 satellite, which launched on an Atlas V rocket in 2014. This industry-leading resolution provides the sharpest view of vital details on the ground, to give customers confidence when making critical decisions. WorldView-4 Satellite As the fifth satellite in the DigitalGlobe constellation, WorldView-4 joins WorldView-1, -2, -3, and GeoEye-1. The addition of WorldView-4 means the constellation can image a location on average of 4.5 times per day at 1-meter ground sample distance or less. WorldView-4 has a global capacity to image 680,000 square kilometers per day and will add to the DigitalGlobe 4-m Payload image library, which spans 16 years and grows every day. Fairing

WorldView-4 also includes industry-leading geolocation accuracy, bi-directional scanning, Payload Adapter rapid retargeting, daily revisits and simultaneous capture of high-resolution and multispectral imagery.

Centaur

Payload Fairing (PLF) RL10C-1 Engine The WorldView-4 spacecraft is encapsulated in the 4-m (14-ft) diameter large payload fairing (LPF). The LPF is a bisector (two-piece shell) fairing consisting of aluminum skin/ stringer construction Aft Stub Adapter with vertical split-line longerons. The vehicle’s height with the PLF is approximately 194 ft. Interstage Adapter Centaur MISSION OVERVIEW The Centaur second stage is 10 ft in diameter and 41.5 ft in length. Its propellant tanks are con- structed of pressure-stabilized, corrosion resistant stainless steel. Centaur is a liquid hydrogen/liquid oxygen- (cryogenic-) fueled vehicle. It uses a single RL10C engine producing 22,900 lbf of thrust. The cryogenic tanks are insulated with a combination of helium-purged insulation blankets, radiation – 66th Atlas V Launch shields, and spray-on foam insulation (SOFI). The Centaur forward adapter (CFA) provides the With more than a century of combined heritage, United Launch Alliance is – 112th ULA Launch structural mountings for the fault-tolerant avionics system and the structural and electrical interfaces the nation’s most experienced and reliable launch service provider. ULA with the spacecraft. has successfully delivered more than 100 satellites to orbit that provide critical capabilities for troops in the field, aid meteorologists in tracking Booster severe weather, enable personal device-based GPS navigation and unlock Booster the mysteries of our solar system. The Atlas V booster is 12.5 ft in diameter and 106.5 ft in length. The booster’s tanks are structur- ally rigid and constructed of isogrid aluminum barrels, spun-formed aluminum domes, and intertank skirts. Atlas booster propulsion is provided by the RD-180 engine system (a single engine with two thrust chambers). The RD-180 burns RP-1 (Rocket Propellant-1 or highly purified kerosene) and Join the conversation: liquid oxygen, and delivers 860,200 lb of thrust at sea level. The Atlas V booster is controlled by the Centaur avionics system, which provides guidance, flight control, and vehicle sequencing functions RD-180 Engine during the booster and Centaur phases of flight.
