Raytheon UK Announces Upgraded GPS Anti-Jam Technology

Raytheon UK Announces Upgraded GPS Anti-Jam Technology

Raytheon UK launched a new enhanced version of its battlefield GPS L1/L2 anti-jam (GPS-AJ) capability, Landshield, this week (October 13–15) at the annual conference of the Association of the U.S. Army (AUSA 2014) in Washington, D.C.

A multi-element antenna with the anti-jam processing in a single small “one-box” form factor that interfaces at the RF level, Landshield is designed to enable GPS equipment to function unimpaired against a full range of hostile jammer types including narrow band, broadband, continuous wave, pulse, swept, and spectrally matched.

Arianespace Inquiry Identifies Source of Galileo Launch Anomaly; Next Attempt Could Come in December

Arianespace Inquiry Identifies Source of Galileo Launch Anomaly; Next Attempt Could Come in December

In a report issued Tuesday (October 7, 2014), an Independent Inquiry Board formed to analyze the cause of the August 22 launch anomaly that placed two Galileo into the wrong orbits has concluded that frozen fuel lines caused a misfiring of attitude control thrusters on the launcher’s Fregat module.

According to the report, the problem can be remedied on the rockets in time for another launch in December, much sooner than some observers had speculated.

A Learning Experience

A Learning Experience

My favorite bumper sticker this month: “Oh, no! Not another learning experience!”

After 20 years of putting together a European GNSS program, disappointment over the skewed launch of the first fully operational Galileo satellites is palpable and widely felt. For end users, it is uniformly bad news, and no system provider that sincerely wants to achieve interoperability and robustness in a system of GNSS systems can relish the European program’s current difficulties.

FAA Begins Opening Airspace to Unmanned Aircraft as NextGen, ADS-B Draw Fresh Scrutiny

Aviation officials Thursday (September 25, 2014) for the first time approved the use of unmanned aircraft for commercial filming in the United States, opening the door to what is expected to be a slow-building gold rush to the skies.

Six companies received exemptions from the existing rules, which generally ban the commercial use of unmanned aerial systems or UAS. The exemptions were granted to RC Pro Productions Consulting LLC dba Vortex Aerial, Aerial MOB LLC, Astraeus Aeria, HeliVideo Productions LLC, Pictorvision Inc., and Snaproll Media LLC.
