Orbital Lifetime Predictions
Orbital LIFETIME PREDICTIONS An ASSESSMENT OF model-based BALLISTIC COEFfiCIENT ESTIMATIONS AND ADJUSTMENT FOR TEMPORAL DRAG co- EFfiCIENT VARIATIONS M.R. HaneVEER MSc Thesis Aerospace Engineering Orbital lifetime predictions An assessment of model-based ballistic coecient estimations and adjustment for temporal drag coecient variations by M.R. Haneveer to obtain the degree of Master of Science at the Delft University of Technology, to be defended publicly on Thursday June 1, 2017 at 14:00 PM. Student number: 4077334 Project duration: September 1, 2016 – June 1, 2017 Thesis committee: Dr. ir. E. N. Doornbos, TU Delft, supervisor Dr. ir. E. J. O. Schrama, TU Delft ir. K. J. Cowan MBA TU Delft An electronic version of this thesis is available at http://repository.tudelft.nl/. Summary Objects in Low Earth Orbit (LEO) experience low levels of drag due to the interaction with the outer layers of Earth’s atmosphere. The atmospheric drag reduces the velocity of the object, resulting in a gradual decrease in altitude. With each decayed kilometer the object enters denser portions of the atmosphere accelerating the orbit decay until eventually the object cannot sustain a stable orbit anymore and either crashes onto Earth’s surface or burns up in its atmosphere. The capability of predicting the time an object stays in orbit, whether that object is space junk or a satellite, allows for an estimate of its orbital lifetime - an estimate satellite op- erators work with to schedule science missions and commercial services, as well as use to prove compliance with international agreements stating no passively controlled object is to orbit in LEO longer than 25 years. -
Echostar Annual Report Year Ended December 31, 2012 March 20, 2013
NASDAQ: SATS 100 Inverness Terrace East Englewood, CO 80112 303.706.4000 | echostar.com EchoStar Annual Report Year Ended December 31, 2012 March 20, 2013 Dear EchoStar Corporation Shareholders; 2012 was a very busy year for EchoStar. One of the most exciting accomplishments for 2012 was the addition of two new satellites to our growing fleet through the successful launches of EchoStar XVI and EchoStar XVII, bringing our total number of owned, leased and managed spacecraft to twenty-two. EchoStar operates the world’s fourth largest commercial geostationary satellite fleet and we continue to solidify our position as a premier global leader in satellite communications and operations. EchoStar ended 2012 with revenue of $3.1 billion, a growth of 13% over 2011. EBITDA in 2012 was $794 million, a growth of 64% over 2011. We generated a healthy $508 million of cash from operating activities in 2012 as a result primarily of the strong net income in 2012 and ended the year with a strong balance sheet with $1.5 billion of cash and marketable securities. EchoStar reached two very important long-term North America goals in 2012 with the market implementation of the HughesNet Gen4 service and the roll-out of the Hopper Whole Home DVR solution for DISH. Both solutions are garnering high praise and rapid adoption by consumers, a glowing testament to the capabilities and ingenuity of the EchoStar team. Additional notable accomplishments for 2012 include the very successful introduction of two new Slingbox retail products, several large enterprise contract renewals and new customers for Hughes data network services around the globe, and above-forecast sales of set-top-box products and video services to our established operator customers. -
