As Galileo FOCs Near Launch, EC Holds Public Consultation on Open Service ICD

Installation of Galileo FOC satellite “Doresa” on the payload dispenser system. The first of two Galileo navigation satellites has been integrated on its payload dispenser system at Europe’s Spaceport in Kourou, French Guiana. The second satellite “Milena” was then installed in a side-by-side arrangement and will be mated atop a Soyuz Fregat upper stage. ESA/CNES/Arianespace/Optique Vidéo du CSG photo by P. Baudon

The European Commission (EC) has opened a public consultation on a newly revised version of the Galileo Open Service Signal in Space Interface Control Document (OS SIS ICD).
 
The consultation will take place through September 22, overlapping the scheduled first launch of fully operational capability (FOC) Galileo satellites on August 21. Details of the consultation process can be found on the EC Directorate-General for Enterprise website.

GPS IIF-7 Successfully Launched; Signal Set Healthy

[Updated September 18, 2014] The U.S. Air Force set GPS satellite SVN-68/PRN-09, launched on August 2, to healthy and usable last night (September 17, 2014). This brings the number of satellites transmitting the L2C signal to 14 and those transmitting the L5 signal to 07. The next GPS-IIF satellite, IIF-8/SVN-69, is tentatively scheduled for launch on Oct 29.

Galileo Team Reports Successful Tracking of Encrypted Commercial Service Signals

The European GNSS Agency (GSA) announced today (July 29, 2014) that a recent 10-day test has successfully tracked and demodulated data from encrypted signals of the Commercial Service (CS) from available Galileo satellites.

Using receivers located in Tres Cantos, Spain, and Poing, Germany, the Early Proof of Concept (EPOC) team tracked encrypted Galileo E6-B and E6-C signals. Non-encrypted E6-B and E6-C signals have previously been tracked.

The Next Big Mac

Here’s the coolest “technology-meets-ingenuity-meets-sustainable-economics” story that I’ve heard in a long time: the International Sun-Earth Explorer-3 (ISEE-3) Reboot Project, a crowd-funded rescue mission to repurpose a 36-year-old NASA spacecraft.

Portland, Oregon USA
√ Adidas has designed every official World Cup ball since 1970. And that’s not all! The Adidas Innovation Team in Portland, Oregon, spent 4 years on a smart soccer ball with a “six-axis MEMS accelerometer sensor package” that can detect speed, spin, strike and flight path data and whip it on over to the special GPS app on your iPhone. The app interprets the data for you, coaches you, and keeps a video to show your friends. On sale now for only $299.

GNSS & Geohazards

Ken Hudnut, U.S. Geological Survey

For at least two decades, GPS experts, geodesists, and public agencies have been working together to develop high-accuracy, large-scale continuously operating GPS reference stations that provide them the capability to monitor and model crustal deformation, tectonic plate movement, and the effects of geohazards such as earthquakes and volcanic eruptions.

Now, GNSS-augmented advance warning systems are going into place that can give us a crucial margin of safety in the event of an earthquake.

And none too soon.
