According to a statement on the UK Government’s official website, as of January 1 the United Kingdom will cease participation in the European Galileo and European Geostationary Navigation Overlay Service(EGNOS) programs. British citizens and other private users are not affected, apparently: “devices that currently use Galileo and EGNOS, such as smart phones, will continue to be able to do so.”

In September, the Agency for Air Navigation Safety in Africa and Madagascar (ASECNA) started broadcasting a satellite-based augmentation system (SBAS) signal over Africa and the Indian Ocean. This marks the first SBAS open service in the region, modeled based on the European Geostationary Navigation Overlay Service (EGNOS).

Six months ago, the FCC unanimously granted Ligado’s amended license modification applications to deploy a low-power terrestrial nationwide network in the L-Band. Petitions for reconsideration remain pending, interest groups continue to agitate for change, Congress awaits answers to conflict-of-interest questions—and Ligado presses forward as planned.

A broad cross-industry coalition sent a strongly worded letter to the Senate Commerce Committee warning that the Federal Communications Commission’s (FCC’s) Ligado Order that impacts GPS, if left in place, “would upend decades of sound spectrum policy, negatively impact a significant cross-section of commercial, federal, and academic users who rely on the many different L-band satellite services, and threaten the safety of most Americans.”

MEMS has moved into the high-end market, and the latest disruptor to take into account is silicon MEMS. That’s micro-electromechanical systems based in silicon chips, for short. Accelerometers with up to 100g range and 70µg bias in a very small form factor — 6 cubic centimeters — are exploding the horizons for inertial applications.
