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”. Think about the subsystems of a satellite, and how your phone can provide those functionalities. You’ll need your satellite to take pictures and communicate with mission control, but you’ll also need to protect it from the harsh environmental factors of space! Upload an image of your creation to the Full STEAM Ahead Exploring CubeSats forums! “Learn one, do one, teach one” - share what you just learned or created with a member of your family! CubeSat structure dimensions: 2 MIT Space Exploration Initiative Outreach PhoneSat: Modeling a spacecraft for remote imaging Dimensions for PhoneSat build. CubeSat Subsystems: Power: how will you power your satellite? Attitude Determination: how will you locate your satellite when it’s orbiting? Communication: how will you talk to and command your satellite? Payload (imager): how often will your camera capture photos, and how will it ‘know’ when to take a picture? Constraints: The cube needs to be exactly 10 cubic centimeters. It needs to open so objects can go inside (your phone or camera!) You can use any materials you like to build it—cardboard, crafts, LEGOs, etc. Testing Procedures: When completed, the CubeSat will be measured on a scale Each CubeSat’s strength will be tested by dropping it from a height of 6 feet If the CubeSat reaches a failing point (the CubeSat cannot retain its shape), students will revise their work based on their testing data as well as feedback provided by other students A new model will be crafted with adjustments moving toward a better CubeSat model solution 3 MIT Space Exploration Initiative Outreach PhoneSat: Modeling a spacecraft for remote imaging New models will be used in a second test. 4.

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 IN-FLIGHT EXPERIENCE RESULTS V4
    PHONESAT IN-FLIGHT EXPERIENCE RESULTS Mr. Alberto Guillen Salas (1,2) [[email protected]] Mr. Watson Attai (1,2), Mr. Ken Y. Oyadomari (1,2), Mr. Cedric Priscal (1,2), Dr. Rogan S. Shimmin (1,2), Mr. Oriol Tintore Gazulla (1,2), Mr. Jasper L. Wolfe (1,2) (1) NASA Ames Research Center, Moffett Field (CA), United States (2)Stinger Ghaffarian Technologies (SGT,) Moffett Field (CA), United States ABSTRACT Over the last decade, consumer technology has vastly improved its performances, become more affordable and reduced its size. Modern day smartphones offer capabilities that enable us to figure out where we are, which way we are pointing, observe the world around us, and store and transmit this information to wherever we want. These capabilities are remarkably similar to those required for multi-million dollar satellites. The PhoneSat project at NASA Ames Research Center is building a series of CubeSat-size spacecrafts using an off-the-shelf smartphone as its on-board computer with the goal of showing just how simple and cheap space can be. Since the PhoneSat project started, different suborbital and orbital flight activities have proven the viability of this revolutionary approach. In early 2013, the PhoneSat project launched the first triage of PhoneSats into LEO. In the five day orbital life time, the nano-satellites flew the first functioning smartphone-based satellites (using the Nexus One and Nexus S phones), the cheapest satellite (a total parts cost below $3,500) and one of the fastest on-board processors (CPU speed of 1GHz). In this paper, an overview of the PhoneSat project as well as a summary of the in-flight experimental results is presented.

  • Thermal and Power Cubesat Subsystem Integration
    Thermal and Power Cubesat Subsystem Integration A project present to The Faculty of the Department of Aerospace Engineering San Jose State University in partial fulfillment of the requirements for the degree Master of Science in Aerospace Engineering By Ernie Eugene Gabriel Alvarez May 2014 approved by Dr. Papadopoulos Faculty Advisor Abstract CubeSats were developed with the intent of giving those with very little to no experience at all the opportunity to participate in hands-on space missions. What makes CubeSats so accessible is that they incorporate commercial-off-the shelf components to reduce cost. CubeSats generally have lower bus voltages and power requirements. The power system can be operated primarily by batteries or directly charged by solar panels with secondary rechargeable batteries aiding. For CubeSats there is a greater demand for more peak and average power from the solar panels. TechEdSat is a NASA Ames Research Center 1U CubeSat made by San Jose State University students in partnership with AAC Microtec. Its mission is to evaluate Space Plug-and-play Avionics (SPA) designed by AAC Microtec, and to perform a communications experiment utilizing the Iridium and Orbcomm satellite phone network. The demand for more power has CubeSat designers researching deployable solar panel systems over the typically used body mounted cell configuration and other ways of increasing power. This in turn could require more attention to the thermal requirements of the CubeSat subsystems. Unlike conventional and larger satellites, the CubeSat employs passive rather than active control methods. One must account for the environmental heating loads on the exterior surface and the internal heat generated by electrical components.
