Спутник технологический. BRICSat-P. [Редактировать]

BRICSat-P (Ballistic Reinforced Communication Satellite) это дешевый космический аппарат на основе платформы 1.5U CubeSat который должен будет продемонстрировать работу Micro-Cathode Arc Thruster (µCAT) – электро-двигательной установки и коммуникационного оборудования. Четыре µCAT ускорителя будут размещены на одной из сторон космического аппарата по его центру и должны будут показать возможности по маневрированию и ускорению. Также на его борту расположены две коммуникационные полезные нагрузки:

  • APRS транспондер работающий на частотах  437.975 и 145.825 Мгц в направлении Земля, борт соответственно.
  • PSK31 транспондер работающий на частоте 28.120 Мгц в направлении Земля-борт (2.5 кГц емкость) и UHF FM в направлении борт-Земля.

Mission The goal of the Autonomous Mobile On-orbit Diagnostic System (AMODS) project is to assure the ability to provide the physical on-orbit interaction needed to generate diagnostic data. AMODS employs a modular, CubeSat style design approach to overcome traditional cost and technological hurdles. Overview AMODS embraces a multiple CubeSat system: 1) several “repair” CubeSats (RSats) with manipulable arms designed to latch onto a host satellite and maneuver, image, and potentially repair various components; and 2) one self-propelled transport CubeSat (BRICSat), a “space tug” with the ability to distribute RSats across a constellation of on-orbit client satellites. The projected cost of an AMODS deployment is less than $150,000 per BRICSat and $25,000 per RSat. Notionally, one BRICSat will be launched with multiple RSats (RSat-1,2,3, etc). Once on orbit, RSat-1 will grapple BRICSat and be transferred to its host satellite, where it will latch on and use its manipulators for locomotion. Thereinafter, BRICSat will return to the depot, and transfer RSat-2 and later RSat-3 to their respective hosts. The RSats will remain on their hosts, monitoring the satellites, visually documenting any features of interest and performing diagnostic and repair tasks as needed. RSat Platform RSat is a 3U (10 x 10 x 33 cm) cube satellite with two 60 cm, seven degree of freedom robotic arms fitted with manipulators. It is intended to operate in constant contact with a host spacecraft. The robotic arms provide access to any external surface of the host. The manipulators will grip to the host satellite and also function as tools. RSat will be equipped with a suite of equipment including a camera to diagnose any on-orbit failures and, in some cases, other instruments as may be required to perform minor on-orbit repairs or maintenance. RSat provides ground controllers with the continued opportunity to physically interact with their spacecraft as if it was on the ground. BRICSat Platform BRICSat is also a 3U CubeSat. Equipped with its own proplusion system, it functions as a completely independent spacecraft. It is a complement to RSat and provides the only propulsive force to the RSat platform in the form of both long term, sustained ∆V for travel between spacecraft (cold gas thruster), and quick pulses (electric propulsion) to allow for proximity operations. A cup-cone magnetic docking system will be built-in to BRICSat and include power and data pass-throughs to electrically link BRICSat and RSat and also allow for them to share power. BRICSat defrays the cost of expensive attitude control, rendezvous and propulsion systems across multiple RSats. Current Missions May 2015: Launch of BRICSat-P Prototype. Validated “in transit” propulsion system. March 2017 : Launch of BRICSat-D Demonstrator. It will conduct additional thruster evaluations and demonstrate the use of an (internally mounted) RSat arm motor. Fall 2017: Launch of RSat-P Prototype. A project demonstration, it will prove RSat’s on-orbit suitability, capability, and accuracy. Fall 2018: Launch of MBSE combines the BRICSat and RSat concepts for the first time. It will validate the AMODS notional mission by demonstrating combined, interactive, and rendezvous capabilities. Team Conceived by a midshipman, and made up wholly of undergraduate students, the AMODS boasts a staff of 70 Midshipmen. Helmed by 2/C Edward Hanlon, 2/C Morgan Lange and 2/C Ben Keegan, AMODS is developing innovative advancements with respect to propulsion and navigation of small satellites. To the best of their knowledge, RSat represents the first time space robotic arms have been installed on such a small platform. Spring 2016 m172454@usna.edu Executive Summary

Atlas V AFSPC-5: ULTRASat CubeSat Summary The Ultra Lightweight Technology and Research Auxiliary Satellite (ULTRASat) consists of 10 CubeSats contained in eight Poly-Pico Orbital Deployers (P-PODs) built by the California Polytechnic State University in San Luis Obispo, CA. The eight P-PODs are integrated into a structure built by the Naval Postgraduate School (NPS) in Monterey, CA. A depiction of the ULTRASat configuration is included. Seven of the eight P-PODs contain a total of nine NROsponsored CubeSats while one of the P-PODs has one NASA-sponsored satellite. A brief description of the CubeSats is provided below. NRO-Sponsored CubeSats USS Langley: Developer: U.S. Naval Academy Configuration: One 3U CubeSat Mission: The USS Langley satellite’s primary objective is to demonstrate the ability to host a web server on a CubeSat which will utilize common TCP/IP internet protocol accessible to any internet user. If proven, there is a potential to use small satellite constellations as networks. The U.S. Naval Academy will also be comparing the internet speed of the space-based network versus terrestrial networks. BRICSat-P: Developer: U.S. Naval Academy and George Washington University Configuration: One 1.5U CubeSat Mission: BRICSat-P stands for Ballistically Reinforced Communication Satellite – Propulsion Test Unit. The primary mission is to characterize the performance of miniature pulse plasma thrusters, developed by the George Washington University, in the space environment while providing an amateur radio communication service. The U.S. Naval Academy also plans to use the thrusters for attitude control and then to deorbit the satellite at the end of the mission. Psat: Developer: U.S. Naval Academy Configuration: One 1.5U CubeSat Mission: Psat stands for ParkinsonSat and its primary mission is a communications payload with two transponders operating in the Amateur Satellite Service. One enables handheld texting and position/data reporting between handheld radios almost anywhere on Earth and/or to the internet. The second can support up to 30 simultaneous text users from laptop type portable ground stations. GEARRS: Developer: Near Space Launch and Air Force Research Lab Configuration: One 3U CubeSat Mission: GEARRS stands for Globalstar Evaluation And Risk Reduction Spacecraft and its primary mission is the demonstrate the use of the Globalstar constellation as a path for near continuous command and control of low-earth orbit space vehicles. AeroCube -8: Developer: The Aerospace Corporation, MIT and eSpace Configuration: Two 1.5U CubeSats Mission: AeroCube-8’s primary mission is to demonstrate NRO-funded research and development products in space. It is a multifaceted technology demonstration mission for novel Carbon Nanotube and Scalable ion Electrospray Propulsion system. Two identical CubeSats will be utilized toward this goal. Optical CubeSat: Developer: California Polytechnic State University (“Cal Poly”) Configuration: Three 3U CubeSats Mission: The “OptiCubes” provide on-orbit targets for ground assets to calibrate sensors for orbital debris studies and small-object tracking improvements. NASA-Sponsored CubeSats Lightsail-A: Developer: Ecliptic Enterprises Corporation, California Polytechnic University San Luis Obispo, Georgia Institute of Technology, Boreal Space, Half-Band Technologies LLC and Stellar Exploration, Inc. Configuration: One 3U CubeSat Mission: LightSail is a privately developed solar sail project conceived and led by The Planetary Society. Designed to demonstrate the viability of using solar sailing for propulsion on a small, 3-unit CubeSat, a spacecraft about the size of a loaf of bread, LightSail is embarking on two missions: this shakedown cruise designed to test out the spacecraft’s systems and a full-fledged solar sailing flight in 2016. As a non-profit space interest group, The Planetary Society invests in innovative technology to advance space exploration and will leverage citizen-funded LightSail to inform future missions among the space community.
