Infrastructure: Spacecraft Overview – TSRQ1 2019
Infrastructure: Spacecraft Overview - TSRQ1 2019 examines global spacecraft/satellite operations conducted throughout the three space sectors, military, civil government, and commercial. This edition covers communication, PNT, and Earth observation/remote sensing…
2016 – Satellite Orbits
As in previous years, the most used orbit type is l##. In 2016, ##% of the ### spacecraft launched or deployed around the Earth were inserted into ##. The effective…
2015 – Satellite Orbits
According to the Union of Concerned Scientists, a total of ## satellites were still operational at the end of 2015. These satellites are mostly located in low Earth orbit (LEO)…
2013 – Satellite Orbits
There were ## active satellites in orbit at the end of 2013, all performing various missions depending on their configuration and orbit. Of all active satellites, ## (approximately ##% of…
2005 – Satellite Orbits
As geostationary (GSO) satellites remain in an essentially fixed position relative to the ground at all times, they can communicate with fixed ground stations continually. Medium Earth orbit (MEO) and…
2014 – Satellite Orbits
According to the Union of Concerned Scientists, a total of ## satellites were active at the end of 2014. These satellites are mostly located in low Earth orbit (LEO) between 200 and…
2009 – Satellite Orbits
Satellites provide a perspective of the Earth that cannot be matched by ground-based technology. In the early days of the Space Age, satellites served little purpose beyond demonstrating that they…
2010 – Satellite Orbits
The closer proximity to the Earth also greatly reduces signal delay from a LEO satellite to ground stations and allows for smaller receivers on the ground. While these attributes are…
2011 – Satellite Orbits
The closer proximity to the Earth also greatly reduces signal delay from a LEO satellite to ground stations and allows for smaller receivers on the ground. While minimizing signal delay…
