Legislation to Stop U.S. Use of Russian Rocket Engines Could Affect GPS

Legislation to Stop U.S. Use of Russian Rocket Engines Could Affect GPS

U.S. Senator John McCain

If approved, legislation halting the use of a Russian rocket engine could force delays in the launch of U.S. military satellites, including, potentially, GPS III spacecraft planned for launch beginning next year.

The bill, introduced this week by Sen. John McCain R-Arizona, the chairman of the Senate Armed Services Committee, and House Majority Leader Kevin McCarthy, R-California, would ban the use of Russian RD-180 rocket engines for the evolved expendable launch vehicle program (EELV).

New ESA Chief Briefs Media, Hails Galileo Progress

New ESA Chief Briefs Media, Hails Galileo Progress

ESA’s Johann-Dietrich Wörner

ESA renewed its New Year’s tradition, briefing the news media on January 15 at the European Space Agency headquarters in Paris, with the agency’s new director general, Johann-Dietrich Wörner, presiding for the first time..  

The contrast with his predecessor, the well-liked Jean-Jacques Dordain, is clear but not stark. Wörner is a bit more whimsical than Dordain, but not too much. His presentation features a few more cartoons, he makes a few more jokes, and there is a picture of the Star Trek (Next Generation) crew to make us chuckle.

SBAS and RNSS: The Unsung Heroes of GNSS

Okay, if I had wanted to pander to GNSS fans, I might have called this, “Making Great Greater.”

But there are only so many superlatives that can be lathered on this remarkable technology before simple praise turns into hagiography.

So, it’s time once more to give a little love to those unsung heroes of GNSS: the augmentations and regional navigation satellite systems.

SwiftNav Releases Specs on UAV-Focus GNSS Receiver Platform

Swift Navigation’s Piksi GPS receiver

Having started out with a crowd source–funded launch through Kickstarter followed by two rounds of more conventional venture capital backing — $2.6 million in 2014 and another $11 million last December — San Francisco, California–based Swift Navigation is going after a low-cost, high-precision market such as unmanned aerial vehicles (UAVs) with its Piksi GPS receiver platform.

Feds Reach Out to Small Companies for GPS Innovations

The federal government is looking to small firms to help solve some of its toughest GPS-related technology problems with many of the projects focusing on countering jamming while others endeavor to simplify signal acquisition and improve links within the constellation. A recent spate of requests for proposals for Small Business Innovation Research (SBIR) contracts have been released by various agencies. These include the following:

Galileo Themes, Threads and Visions

Galileo Themes, Threads and Visions

Europe’s space community rang in the New Year with two of its brightest annual fixtures: the European Union (EU) Space Policy conference in Brussels and the European Space Agency (ESA) media briefing in Paris.

The events brought out all of the relevant voices and served to illustrate not only the disposition of materiel and troops but also their intent and even the level of morale.

GNSS Satellite-Based Augmentation Systems

Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.

With the support of the European Space Agency (ESA), a European team designed a frequency- and time-transfer process and validated its performance in a complex navigation test bed. This two-way time-transfer technology took advantage of the following:
