By separating the motion into these three components we are able to give a full description of the motion, but in a simple form avoiding much of the complexity in other formulations. We then use this model to find expressions for the motion of one satellite with respect to another within ...
Low earth orbit satellites orbit from 160 to 2000 km above the Earth, take approximately 1.5 hours for a full orbit, and only cover a portion of the Earth’s surface. The mass of a satellite has a significant impact on the launch of the satellite. This is because the heavier the satelli...
Wirth did an entire series on inequitable credit practices that devalued and punished women. “If a woman got married and changed her name she immediately lost all of her credit history,” says Wirth. “Banks assumed the credit rating belonged to the husband even if the women worked full tim...

It has so far launched two-thirds of its planned 648-strong LEO satellite constellation. Telesat's LEO IFC service has also been hit with delays due to supply chain issues. "At this point, we're expecting to begin launching in 2025 and offer full global services in 2026, and...

This article introduces key market trends driving low Earth orbit (LEO) satellite deployments. It will discuss the basic operation of a LEO satellite system and present some of the semiconductor RFIC advances, which are enabling the next generation of Ku and Ka band LEO ...
full hemispherical tracking but, unlike the azimuth-elevation pedestal that is unable to continuously track high elevation passes, the X-Y pedestal has its limitations at low elevation angles (< 2°) around 90° and 270° in azimuth. At these elevations the satellite moves slowly with respect ...
The Huginn and Muninn demonstration missions are the first step toward deployment of Pulsar, Xona’s commercial PNT service. In its ultimate form, this embodies a LEO constellation of several hundred satellites, delivering GPS-level satellite visibility and geometry and full PNT services that are pre...
