Wire harnesses are bundled assemblies of cables and connectors, that are used to transmit signals and power between components. If we could compare a satellite to the human body, the electrical harness would represent the blood vessels conveying the power and the nervous network transmitting the commands and sensor information …

Global interest in nano and microsatellites (< 100kg) is increasing. The miniaturization of electronics, together with reliability and performance increase as well as reduction of cost, have allowed the use of commercials-off-the-shelf in the space industry, fostering the Smallsat use. Many nanosatellites (<10 kg) are used for educational purposes, and …

Remote sensing is the science of acquiring information about the Earth’s surface without actually being in contact with it. This is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information. Unlike optical satellites that capture reflected sunlight to produce detailed photos of Earth, …

The Global Positioning System (GPS), is a global navigation satellite system (GNSS) that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. GPS has become ubiquitous technology that provides real-time …

The US China, and Russia have also reportedly developed so-called “inspection satellites” that can maneuver close to other spacecraft in low orbits and examine them for malfunctions. The robots could fix minor maintenance issues, keeping up with current orbiters as they age and sustain damage. However, this technology is …

Recently many companies have launched large constellations of satellites to deliver broadband Internet to serve nearly 2 billion people around the world that live in areas that lack mobile coverage, mostly far from major cities, which makes building a network of terrestrial cell towers to connect them prohibitively expensive. These …
