Ion beam accelerator for nuclear device characterization, detection of contraband materials, and Directed energy weapons

Ion beam accelerators are machines providing kinetic energy to charged particles called ions, which bombard the target sample – the material to be irradiated and subsequently analyzed. The target can be a thin foil or a piece of mineral, rubber, textile, tissue, soil or metal. The sample can be an …

Satellite Command and data handling (C&DH) & On-board computer (OBC)

Spacecraft are man-made machines that operate in space. An orbiting spacecraft is normally referred to as a satellite, although it is manmade as opposed to a natural satellite like our moon. A spacecraft is typically subdivided into two major parts, the payload and the bus. The bus provides the structural body …

Military Specifications and Standards

Defense standards evolved from the need to ensure proper performance, maintainability and reparability (ease of MRO), and logistical usefulness of military equipment. The latter two goals (MRO and logistics) favor certain general concepts, such as interchangeability, standardization (of equipment and processes, in general), cataloging, communications, and training (to teach people …

Electric Power Subsystem (EPS) is a vital subsystem of satellite

Satellite present in an orbit should be operated continuously during its life span. All the satellites require internal power in order to operate various electronic systems and communications payloads that are present in it. The Electrical Power System (EPS) is a vital subsystem whose primary role is to supply satellite …
