DARPA V-SPELLS to develop automated tools for understanding, Re-engineering and Assurance of legacy software of Defense and Aerospace systems

The complexity of  aerospace and defense software has grown manyfold. For example, the U.S. Air Force F-22 Raptor jet fighter, consists of about 1.7 million lines of software code, while the F-35 joint strike fighter has about 5.7 million lines of code to operate its onboard systems. Boeing’s new 787 …

Hybrid Free Space Optics (FSO)/Radio Frequency (RF) communication systems can improve the performance of Free space optical communications

Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. “Free space” means air, outer space, vacuum, or something similar. FSO operates on the Line-of-Sight phenomenon, consisting of a LASER at source and detector at …

Free space laser communications technologies for Aircrafts, Satellites, Moon and Mars communication

If humans want to travel about the solar system, they’ll need to be able to communicate. We communicate with robotic missions through radio signals. It requires a network of large radio antennas to do this. Spacecraft have relatively weak receivers, so you need to beam a strong radio signal to …

RF/Microwave Switching Technologies

One of the most common functions in all electronic circuitry is switching. Switching has a wide range of uses. Engineers in industries ranging from telecommunications to military/aerospace need high-performance RF/microwave switching as part of their test setups. An RF switch or microwave switch is a device to route high frequency …

Faraday rotator mirror

Michelson proposed an interferometric apparatus in 1890 following an earlier suggestion by Fizeau. The invention became the precursor of many important modern optic measurement techniques. The Michelson Interferometer, as it is called, is used to measure small optical path length changes. The classic Michelson Interferometer consists of two mirrors (one forming …

US Army’s JUDI is employing Conversational AI to imrpove soldier-robot interaction for Manned-unmanned teaming (MUM-T)

Since fully autonomous UAS are still far off, the  US Army has developed concept of Manned-unmanned teaming (MUM-T)  for operation in A2/AD environments. Through MUM-T operations they expect to combine the strengths of manned and unmanned  platform to increase situational awareness, allowing the armed forces to conduct operations that include …

Military DC-DC Converters require qualified end product, components, materials and processes, Space level hybrid DC-DC Converters require radiation tolerance or radiation hardening

A DC-to-DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter. Power levels range from very low (small batteries) to very high (high-voltage power transmission).   In most of …

US Army developing Manned-Unmanned Teaming ( MUM-T ) technologies in multiple domains for operation in A2/AD environments

US military is facing increasingly Anti-access /Area denial environment, a set of overlapping military capabilities and operations designed to slow the deployment of U.S. forces to a region, reduce the tempo of those forces once there, and deny the freedom of action necessary to achieve military objectives . Unmanned Air …
