OBJECTIVE: Develop novel CubeSat payloads for Naval space missions.
DESCRIPTION: Nano-satellites are popular among universities and gaining momentum with commercial and government organizations. Standards based satellite buses and deployment mechanisms, such as the CubeSat and Poly Pico-satellite Orbital Deployer (P-POD), have stimulated growth in the area. Small satellites have proven capable and cost effective in many areas traditionally dominated by large satellites, however many challenges remain.
Beyond state of the art research is needed to drastically reduce the size, weight and power of payloads that have traditionally performed Naval space missions on much larger satellites. Traditional Naval space missions include narrowband communications (UHF Follow On, Mobile User Objective System), astrometry (Joint Milli-Arcsecond Pathfinder Survey), and ocean sensing (GEOdetic SATellite, GEOSAT Follow On). Other missions of Naval interest will also be considered. Smaller, more cost effective satellites will enable the Navy to continue vital space missions despite limited resources.
One important consideration in developing a new CubeSat payload technology is mission life. Most CubeSats are deployed in Low Earth Orbit (LEO) where atmospheric drag is considerable. Since they generally do not carry propellant for station keeping, atmospheric drag is often a mission life limiting factor. The technology’s impact on mission life must be weighed in the design process.
Novel technologies will enable CubeSats to expand from university experiments to operational missions. It can be assumed that approximately two thirds of the 3-U spacecraft size, weight and power will be used for power management, attitude control, communications and other basic spacecraft functions. In general, proposed payloads should:
PHASE I: Develop a novel payload design for CubeSats to support a Naval space mission. Payloads of interest include:
Tasks under this phase could include:
PHASE II: Build a prototype payload and test it in the space environment.
PHASE III: This phase will focus on integrating the technology into potential Naval CubeSat missions.
PRIVATE SECTOR COMMERCIAL POTENTIAL DUAL-USE APPLICATIONS: The technologies developed under this topic can be applied to a variety of commercial, military and space exploration CubeSat missions.
