The White House is asking Congress to boost overall funding for the GPS program back over $1 billion, with the largest infusion of new money earmarked to cover the cost growth of the Next Generation Operational Control System (OCX).

If approved, overall spending on the GPS program would reach $1.09 billion in fiscal year 2018 (FY18) with funding for OCX surging to $510.94 million from the $393.27 million allocated by Congress for FY17.

Two More Satellites Formally Added to Galileo’s Satnav System

Two further satellites — increasing the total number to 16 — have formally become part of Europe’s Galileo satnav system, broadcasting timing and navigation signals worldwide while also picking up distress calls across the planet.

These are the 15th and 16th satellites to join the network, two of the four Galileos that were launched together by Ariane 5 last November, and the first additions to the working constellation since the start of Galileo Initial Services in December.

1. RESCUE DRONE
Noordwijk, Netherlands
√ Inspired by the refugee crisis, Dutch start-up Avy has been working on robust, long-duration drones capable of detecting people in distress and, if necessary, dropping life jackets, life buoys, food and medicine. The rescue drone can take off from a boat or the shore, carrying among other items, a cylinder that contains a large deployable rescue buoy, which not only can keep refugees afloat but indicates its location to boats in the vicinity.

For several years the European Union (EU) has sought a waiver for its Galileo system from Federal Communications Commission (FCC) licensing requirements — the so-called Part 25 rule to operate in this country.

Long-overdue approval of the request should be expedited by the FCC.

New Research Says Turbulence Not to Blame for GNSS Outages During Northern Lights

Last week, researchers at the University of Bath in England announced findings indicating for the first time that turbulence does not take place within the Northern Lights and instead that unknown mechanisms are responsible for the outages of GNSS. This research concludes that new technology can be developed to overcome these outages from the Northern Lights, also known as aurora borealis.
