UNCLASSIFIED / / PO@TReOPSTCIRE USE one Laser Lightcraft Nanosatellites Summary Miniaturized satellites are spacecraft of unusually low mass and small size, usually under 500 kg in total mass. The term “minisatellite” refers to a spacecraft with a wet mass (including onboard propellant) of 100 kg to 500 kg. Microsatellite or “microsat” is a spacecraft with a wet mass of 10 kg to 100 kg. Nanosatellite or “nanosat” is a spacecraft with a wet mass below 10 kg. Picosatellite or “picosat” is a spacecraft with a wet mass of 0.1 kg to 1.0 kg. Picosats are also called sub-nanosats. The primary reason …

UNCLASSIFIED/ /PORMOTMPEGH US EO tial Chapter 1: Nanosatellite Technologies OVERVIEW Nanosats require technologies that radically reduce the mass and power of components without compromising performance. In addition to miniaturizing components, methods to integrate similar functions across subsystems are being evaluated. For example, all subsystem electronics, including instruments, could be integrated within the Command and Data Handling (C&DH) subsystem. Multifunctional solutions also offer significant savings over traditional approaches. Technology investments are required to develop or ada…

UNCLASSIFIED / / P@?feOP PTC USO Miniaturized solid propellant gas generators could be used as ACS thrusters. Forty- eight 50 mN-sec pulses are required to reorient the nanosat after it achieves the required orbital altitude. Although this could be achieved either by a monopropellant or a cold gas thruster, it could also be achieved using an array of gas generators. Such miniaturized gas generators have already been successfully built and commercialized by companies such as MOOG and Lockheed-Martin Space Systems. By incorporating micro-electromechanical systems (MEMS) techniques, the devices h…
