Launch and Deployment Analysis for a Small, MEO, Technology Demonstration Satellite
46th AIAA Aerospace Sciences Meeting and Exhibit AIAA 2008-1131 7 – 10 January 20006, Reno, Nevada Launch and Deployment Analysis for a Small, MEO, Technology Demonstration Satellite Stephen A. Whitmore* and Tyson K. Smith† Utah State University, Logan, UT, 84322-4130 A trade study investigating the economics, mass budget, and concept of operations for delivery of a small technology-demonstration satellite to a medium-altitude earth orbit is presented. The mission requires payload deployment at a 19,000 km orbit altitude and an inclination of 55o. Because the payload is a technology demonstrator and not part of an operational mission, launch and deployment costs are a paramount consideration. The payload includes classified technologies; consequently a USA licensed launch system is mandated. A preliminary trade analysis is performed where all available options for FAA-licensed US launch systems are considered. The preliminary trade study selects the Orbital Sciences Minotaur V launch vehicle, derived from the decommissioned Peacekeeper missile system, as the most favorable option for payload delivery. To meet mission objectives the Minotaur V configuration is modified, replacing the baseline 5th stage ATK-37FM motor with the significantly smaller ATK Star 27. The proposed design change enables payload delivery to the required orbit without using a 6th stage kick motor. End-to-end mass budgets are calculated, and a concept of operations is presented. Monte-Carlo simulations are used to characterize the expected accuracy of the final orbit. -

JoSSonline.com Lessons Learned Using Iridium to Com- municate with a CubeSat in Low Earth Orbit Vincent J. Riot, Lance M. Simms, and Darrell Carter Lawrence Livermore National Laboratory Livermore, CA, USA Abstract This paper presents the design and approval process for operating an Iridium transceiver on orbit and provide on-orbit performance data obtained from a CubeSat platform in Low Earth Orbit (LEO) (500 km orbit). On-orbit data demonstrates that use of a commercial, low-cost Iridium transceiver can serve as a valuable communication approach for low volume telemetry with less than a 30-minute lag for approximately 90% of the time. We also demonstrate that a radial differential velocity of 7 km/sec corresponding to about a 37.5kHz doppler shift and a distance of less than 2,000 km can be used for mission planning.

Phonesat: Modeling a Spacecraft for Remote Imaging
MIT Space Exploration Initiative Outreach PhoneSat: Modeling a spacecraft for remote imaging Avery Normandin Published on: Apr 02, 2020 License: Creative Commons Attribution 4.0 International License (CC-BY 4.0) MIT Space Exploration Initiative Outreach PhoneSat: Modeling a spacecraft for remote imaging Activity: creating a small satellite to protect your cell phone in outer-space environments! Background: Small satellites are constantly orbiting Earth, providing useful data about the planet over time. These satellites are designed and built by engineers to withstand the harsh space environment. A “cubesat” is a specific type of small satellite that has very particular specifications, making it easier for people around the world to design and launch. Today, you’ll be turning your phone into a mock-satellite! Mission: It’s your first visit to space as NASA’s newest astronaut - congratulations! Your first mission is to deploy a 1U (10 x 10 x 10 cm) small satellite that takes pictures of the plants and trees in your neighborhood. Your plan is to thrust the satellite into orbit by throwing it outside the International Space Station (ISS). However, during launch, you hear a loud crash - the satellite you have spent the last year designing and building has fallen and broken! Mission control informs you that you are still responsible for getting a satellite into orbit upon your arrival to the ISS. Your new mission is to rebuild the satellite and test a prototype first at home -- one that takes. The only ‘computer’ available to run your satellite? Your smartphone! Using the constraints defined by a cubesat, you will be creating a prototype structure that nests your phone as a “satellite payload”. -
January 2018 Satellite & Space Monthly Review
February 5, 2018 Industry Brief Chris Quilty [email protected] January 2018 +1 (727)-828-7085 Austin Moeller Satellite & Space Monthly Review [email protected] +1 (727)-828-7601 January 11, 2018: Air force to utilize more smallsats for weather DMSP F19 Readying for Launch observation. Citing growing budget constraints, the US Air Force announced that is considering using small satellites in combination with next-gen software rather than procuring traditional multibillion-dollar, cost-plus spacecraft to replace/replenish its Defense Meteorological Satellite Program (DMSP). Despite awarding a $94 million contract to Ball Aerospace in November to design the Weather System Follow-on Microwave (WSF-M) satellite, the Air Force plans to begin launching small satellites equipped with infrared imaging and electro-optical instruments to monitor battlefield weather starting in 2021-2022. The Air Force is also considering augmenting their current capabilities with inactive NOAA GOES satellites in the near-term. These considerations parallel recent comments by USSTRATCOM commander Gen. John Hyten, who has repeatedly stated that the Air Force currently spends too much time and money developing large, high- cost satellites, and needs to invest in more small satellites for strategic Source: Lockheed Martin and budgetary reasons. Conclusion: Smallsats ready for a DoD growth spurt? With growing evidence of Russian/Chinese anti- satellite technology demonstrations, the Pentagon is becoming increasingly reluctant to spend billions of dollars on monolithic “Battlestar Galactica” satellite systems that place too many eggs in one basket. While not as robust or technologically-capable as high-end spacecraft built by traditional contractor, such as Lockheed Martin, small satellites are orders-of-magnitude less expensive to build, launch, and maintain. -
The Space Sector in 2014 and Beyond
The Space Economy at a Glance 2014 © OECD 2014 Chapter 1 The space sector in 2014 and beyond Chapter 1 reviews major trends in the space sector. It first provides a review of the “space economy” in 2014. It then focuses on an original analysis of global value chains in the space sector, including a spotlight on fifty years of European space co-operation. The chapter also looks at new dynamics in the sector, which may impact incumbents and new entrants, with a focus on innovation in industrial processes and the development of small satellites. 15 1. THE SPACE SECTOR IN 2014 AND BEYOND Defining the “space economy” in 2014 Straddling the defence and aerospace industries, the space sector has for decades been a relatively discrete sector, developed to serve strategic objectives in many OECD and non-OECD economies, with security applications, science and space exploration. The space sector, like many other high-tech sensitive domains, is now attracting much more attention around the world, as governments and private investors seek new sources of economic growth and innovation. The “space economy” has become an intriguing domain to examine, bringing interesting innovation capacities as well as new commercial opportunities. Over the past decade, the number of public and private actors involved in space activities worldwide has increased, spurring even further the development of the nascent space economy. Despite strong headwinds in many related sectors (e.g. defence), the space sector overall has not been significantly affected by the world economic crisis. It remains a strategic sector for many countries, relatively sheltered because of national imperatives (e.g. -

The United States has responded by insisting that existing treaties and rules governing the use of space are sufficient. The standoff has produced a six-year deadlock in Geneva at the United Nations Conference on Disarmament, but the parties have not been inactive. Russia and China have much to lose if the United States were to pursue the programs laid out in its planning documents. This makes prob - able the eventual formulation of responses that are adverse to a broad range of U.S. interests in space. The Chinese anti-satellite test in January 2007 was prelude to an unfolding drama in which the main act is still subject to revi - sion. -
