To date, most university satellites require several yea

27、rs to develop and significant financial resources, making them prohibitive for small programs. New technological developments in small low-power electronics make smaller, lower-cost satellites feasible.The CubeSat program has developed a picosatellite standard that significantly reduces the cost and

28、 development time of picosatellites with a specific form factor. In addition, CubeSats can serve as platforms for in-space experimentation, as well as a means of space-qualifying future small-satellite hardware.The CubeSat Standard is an evolution of the picosatellites developed for Stanfords OPAL m

29、ission. CubeSats are constrained to a 100 mm cube (not including deployment interface rails) with a mass of one kilogram or less. Led by Stanford Universitys Space Systems Development Lab (SSDL), the CubeSat project is developed jointly by universities and industry worldwide. Within this internation

30、al community CubeSat developments at the California Polytechnic State University (CalPoly) have been twofold: first, develop the standardized launcher-interface/deployer mechanism for CubeSats, and second, demonstrate the feasibility of developing a working CubeSat using low-cost, commercial off-the

31、-shelf components. The project involves a multidisciplinary team of software, aerospace, manufacturing, electrical, and mechanical engineering undergraduate students.In recent years, more sophisticated capabilities have been demonstrated in CubeSats by major space corporations and major space custom

32、ers. CubeSat concepts for inclusion in Mars exploration are in development. Entire companies have been established to solely support the global CubeSat marketplace.

33、CubeSats, CubeSat Deployer and related verification of assurance/quality terms and metrics.This document defines a unique class of picosatellite, the CubeSat. CubeSats are ideal as space development projects for universities around the world. In addition to their significant role in educating space

34、scientists and engineers, CubeSats provide a low-cost platform for testing and space qualification of the next generation of small payloads in space. A key component of the project is the development of a standard CubeSat Deployer.This Deployer is capable of releasing a number of CubeSats as seconda

35、ry payloads on a wide range of launchers. The standard Deployer requires all CubeSats to conform to common physical requirements, and share a standard Deployer interface. CubeSat development time and cost can be significantly reduced by the development of standards that are shared by a large number

36、of spacecraft.Normative control of the CubeSat design, qualification and acceptance testing is generally applied from other small satellite specific standards with the exception of CubeSat/Deployer launch environment test.2 Normative referencesThe following documents are referred to in the text in s
