3D printing or additive manufacturing is ongoing revolution in manufacturing with its potential to fabricate any complex object and is being utilized from aerospace components to human organs, textiles, metals, buildings and even food. Additive manufacturing is defined by ASTM International as the process of joining materials together, layer by …
Read More »The operation of artificial satellite systems involves three main components: the space segment, user segment, and ground segment. The space segment consists of the satellite or constellation of satellites in orbit, along with the uplink and downlink satellite links. The user segment includes the end-user devices that interact with the …

Whether in the field of battle, search-and-rescue or humanitarian aid efforts, the ability to share real-time, networked information between ground, sea and airborne forces is rapidly becoming the defining factor in a mission’s success. However modern satellite and other communications systems in higher frequecies are under constant threat from adversaries …
Read More »Software Defined Radio (SDR) refers to a radio communication system where most of the traditional radio hardware components, such as filters, amplifiers, and modulators/demodulators, are replaced with software running on a general-purpose computer. In an SDR system, the analog signals received by the antenna are digitized by an analog-to-digital converter …
Read More »Where conventional satellites were earlier tailored to comply with single mission requirements, satellite developers are gradually adapting the vision of software-defined satellites which can be reprogrammed and reconfigured, to allow a satellite to take up new applications and expand its performance. Instead of viewing a satellite as a monolithic piece …

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 …

What we are seeing is that the world has entered an era of intense competition in almost all spheres including geopolitical, economic, military, technology and industry. On one hand, competition is helpful as it speeds up innovation and development. On the other hand, when it becomes unmanageable and employs unfair …
Read More »In the history of spaceflight, almost all spacecraft have been manufactured and assembled on the ground, then integrated into a launch vehicle for delivery into orbit. This approach imposes significant limitations on the size, volume, and design of payloads that can be accommodated within the fairing of a single launch …
