DARPA Ouija employing very low- Earth orbit (VLEO) satellite sensors to predict military high-frequency (HF) radio communications

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 …

From the ground to the skies: How SDRs are shaping the future of military communication

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 …

Digital Intermediate Frequency Interoperability (DIFI) Consortium

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 …

Satellite Telemetry, tracking and command (TT&C) Subsystem is a crucial part of any space mission

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 …

Emerging Space based or Space for space economy

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 …

Propulsion technologies for Space logistics, In-Space Assembly (OOS / ISA), automated satellite on-orbit servicing (OOS)

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 …

DARPA SPCE improving efficiency of radiation-tolerant Power convertors for Military LEO Satellites

The space industry is set to expand to over $8.8 billion dollars by 2030 fueled by the rapid increase in the number of small satellite launches and decreased costs resulting from rideshare companies and programs   A satellite present in an orbit should be operated continuously during its life span. …
