Passive and Active Soldier Armor cooling enhance soldier performance in extreme environments

The wearing of body armour  provide troops an unparalleled advantage on the battlefield, improving survivability and reducing casualtiesis. It has also been very effective in reducing injuries and fatalities within the police force and correctional services.   This protection comes at a price, however. U.S. ground troops today carry an …

Satellite On-board connectivity through beam switching and scanning

High-throughput Satellite or HTS systems represent a new generation of satellite communications systems, that provide a significant increase in capacity than conventional communication satellites. They utilize frequency reuse and multiple spot beams to deliver vast throughput for the same amount of allocated orbital spectrum. The increase in capacity typically ranges from 2 …

Digital Signal Processing (DSP) algorithms and Digital Signal Processors

Digital Signal Processors (DSP) take real-world signals like voice, audio, video, temperature, pressure, or position that have been digitized and then mathematically manipulate them. Signals need to be processed so that the information that they contain can be displayed, analyzed, or converted to another type of signal that may be …

DVB S2/S2X standards for HDTV broadcasting and broadband satellite networkss

A satellite broadcast network consists of a transmitting hub station and a number of receive-only earth stations, and uses the resource of one or several channels (transponders) of a communications satellite. It relies on a star topology and point-to-multipoint connectivity. Links are unidirectional, from the hub towards the earth stations. …

New Space Satellite Communication Networks and terminals Test & Measurement challenges and solutions

Traditionally, the satellite industry has relied on geosynchronous earth orbit (GEO) satellites that take years to build and require very expensive launches to deliver them to orbit. Satellite networks using geosynchronous equatorial orbit (GEO) are effective at providing stationary coverage to a specific area, however, Latency issues due to the …

Model-Based Systems Engineering (MBSE) for Satellites and Aerospace

A system is defined by NASA as  a construct or collection of different elements that together produce results not obtainable by the elements alone. Systems Engineering (SE) is defined as: The process by which a customer’s needs are satisfied through the conceptualization, design, modeling, testing, implementation, and operation of a …

Agile Engineering is the Future of Aerospace Design and Production

In the middle of the 1990s, the common way of developing software was a heavyweight software development methodology, comprising of complete requirements documentation of design and architecture, followed by coding, integration, and finally testing based on a detailed test plan before an application was deemed production-ready. This traditional and sequential life …

Device drivers provide software interface to hardware devices

In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. The main purpose of device drivers is to provide abstraction by acting as a translator between a hardware device and the applications or operating …

System Architecture to Software Archtecture

All systems are designed to achieve some human purpose: The web application Facebook connects people in a social network, an aircraft transports people long distances. A Boeing spokesman once quipped, “We view a 777 airliner as a collection of parts flying in close proximity.”   The job of a systems …

Phased Array Antennas for LEO satellite Constellation Ground Station

Satellite communication systems consist of two main segments, the space segment and the earth or ground station. The ground station system coordinates the communication process with satellites in space. A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication …
