Mike Veth: Engineering Meets the Wild Blue Yonder

Veth proudly poses with his RV-8A fuselage components securely fastened in a jig. The RV-8A is a two-place, tandem, experimental aircraft that is home-built from kit components. When completed, he plans to use the aircraft as an experimental navigation testbed.

SIDEBAR: Mike Veth’s Compass Points

Over the course of Lt. Col. Michael Veth’s 20-year career in the U.S. Air Force (USAF), certain navigation technologies may have changed dramatically, but working toward increased accuracy has remained a constant.

From Fledgling to Flight

Allure Shadow (top), structural clearances (bottom)

The Boeing Company initiated the Unmanned Little Bird (ULB) program in the fall of 2003 to create a developmental platform for an optionally manned, vertical takeoff and landing (VTOL) unmanned aerial vehicle (UAV). Initial flight test activity employed a modified MD530FF helicopter, with the first flight taking place on September 8, 2004. Six weeks later the program achieved a fully autonomous multiple waypoint demonstration flight from takeoff through landing.

The Sequester and Its GPS Discontents

The Sequester and Its GPS Discontents

Deep military spending cuts set to kick in March 1 will likely slow efforts to modernize the GPS constellation, insiders agree, in large part because many of the personnel needed to push the program forward will be sitting at home, unpaid, one day out of every five.

The human impact of the deep cuts taking effect when sequestration kicks in on Friday was already evident in mid-February during the program review conference held by the Association for Unmanned Vehicle Systems International.

GAO Report on Receiver Performance Invokes GPS LightSquared Controversy

A U.S. Government Accountability Office (GAO) study on receiver performance and increased availability to radio frequency spectrum reveals just how complicated the issue underlying the GPS/LightSquared controversy is.

On February 22, the GAO sent the report — entitled “Spectrum Management – Further Consideration of Options to Improve Receiver Performance Needed” — to the Senate Committee on Commerce, Science, and Transportation and House Committee on Energy and Commerce.

Speaking privately at the recent European Union (EU) Space Conference in Brussels, one individual said, “Relations between the European Commission (EC) and the European Space Agency (ESA) are worse than ever."

That would be very bad indeed, given the two bodies’ history of knocking heads.

And what’s at the center of this new rift? “It’s about power,” said this source, who would know.

Well, the lights work. So far, so good.

The Lockheed Martin team developing the U.S. Air Force’s next-generation GPS III satellites has turned on power to the system module of the program’s first spacecraft, designated GPS III Space Vehicle One (SV-1).

According to the prime contractor, the achievement is a key indication that the team is on track to deliver the first satellite for launch availability next year, although the actual first launch will probably take place in 2015.
