How Does Starlink Work Anyway?

No matter what you think of Elon Musk, it’s hard to deny that he takes the
dictum “There’s no such thing as bad publicity” to heart. From hurling
sports cars into orbit to solar-powered roof destroyers, there’s little
that Mr. Musk can’t turn into a net positive for at least one of his many
ventures, not to mention his image. Elon may have gotten in over his head,
though. His plan to use his SpaceX rockets to fill the sky with thousands
of satellites dedicated to providing cheap Internet access ran afoul of the
astronomy community, which has decried the impact of the Starlink
satellites on observations, both in the optical wavelengths and further
down the spectrum in the radio bands. And that’s with only a tiny fraction
of the planned constellation deployed; once fully built-out, they fear
Starlink will ruin Earth-based observation forever.

Motorola Solutions awarded $764 million in trade-secret theft case against
Hytera

A federal jury in Illinois today ruled unanimously that Hytera
Communications stole land-mobile-radio (LMR) trade secrets and infringed
upon copyrights owned by Motorola Solutions, awarding $764.6 million in
damages to the Chicago-based, LMR-industry giant. Originally filed in March
2017, the trade-secret theft lawsuit was part of Motorola Solutions’
multi-pronged legal attack against Hytera, which included claims before the
U.S. International Trade Commission (ITC) and a separate
patent-infringement litigation. In July 2018, Motorola Solutions added a
copyright-infringement complaint to the trade-secret theft lawsuit,
alleging that Hytera unlawfully copied Motorola Solutions’ source code into
Hytera products.

AMSAT reports that the pioneering AMSAT-OSCAR 85 (AO-85) CubeSat, also
known as Fox-1A, has gone silent. “Having not been heard throughout the
most recent period of full illumination, it is reasonable to believe the
batteries have deteriorated to the point of no longer being able to power
the transmitter,” AMSAT said this week. “Should some future event cause a
cell to open, it is possible the s...

The W8S DXpedition to Swains Island in the Pacific, set to take place in
mid-March, has been postponed until fall as a result of travel restrictions
imposed on individuals entering American Samoa, stemming from the recent
coronavirus outbreak. The Department of Health allows non-residents to
enter American Samoa only via Hawaii after a 14-day mandatory quarantine in
Hawaii, and the DXpedition w...
