Earth's rotation is randomly speeding up, and nobody is quite sure why. These speedups, which have occurred several times over the last few years, haven't had any effect on daily life, but they also ...
Precise orbit determination (POD) is vital for satellite navigation, positioning, and timing services, especially as large Low Earth Orbit (LEO) constellations grow in scale. A new method integrates ...
