There has been exponential growth in debris accumulated from over 60 years of space activities. It is estimated that the total number of space debris objects in Earth orbit is in the order of: 22,000 – for sizes larger than 10 cm, 600,000 – for sizes larger than 1 cm …

It is anticipated that the world will face increased competition for limited and finite natural resources given a growing population, increasing pressure on our food and health systems, and climate change and associated environmental degradation decimating our primary production systems. Synthetic biology is defined as the application of science, …

Multibeam satellite systems make it possible to reduce the size of earth stations and hence the cost of the earth segment. Frequency re-use from one beam to another permits an increase in capacity without increasing the bandwidth allocated to the system. With single beam antenna coverage, it is therefore …
Read More »The overarching goal of quantum information science and its enabled emerging quantum technologies is to demonstrate capabilities beyond what is allowed by their classical counterparts. Sensing is an arena that quantum technologies can achieve advantages over classical sensing technologies for practical applications in the near term. Quantum metrology studies the …

The electromagnetic spectrum is a series of frequencies ranging from radio waves to microwaves, visible light, X-rays, and gamma rays. As the wavelength of the electromagnetic radiation shortens, the waves have a higher frequency—how quickly electromagnetic waves follow each other—and therefore more energy. Ultraviolet (UV) is electromagnetic radiation with …

Autonomous ships refer to the ships that are remote built ships where operations are performed by remote control mechanism. These operations are operated by the humans located at the shore. Autonomous requires high quality systems and reliable communication system which work with the assistance of connectivity, control algorism and sensor …
Read More »Photonics is rapidly transforming into an enabling space technology with potential to cross-fertilize multiple markets in the space domain. Among them: navigation, remote sensing and telecommunications, as well as ground-breaking scientific and planetary exploration missions. Because of advantages related to bandwidth, mass, power consumption, beam size and immunity to …

Today, we are witnessing the second quantum revolution, where quantum states, which can exhibit superposition and entanglement, are harnessed for quantum technological applications. Quantum Sensing exploits the high sensitivity of quantum systems to external disturbances to develop highly sensitive sensors. Breaking the limitations of today’s established imaging schemes is a …

Nanosatellite and microsatellite refer to miniaturized satellites in terms of size and weight, in the range of 1-10 Kg and 10-100 kg, respectively. ‘CubeSat’ is one of the most popular types of miniaturized satellites. These are the fastest growing segments in the satellite industry. One of the major advantages of nano …
