The U.S. Air Force Space Command (AFSPC) invited comments today (March 20, 2013) on its proposed plans to test CNAV message capabilities on the GPS L2C and L5 signals June 15–29.
The signals are part of the GPS modernization program and will provide, among other things, greater capability for civilian users. The notice was posted in the official government Federal Register.

L-3 Interstate Electronics Corporation (L-3 IEC) announced today (March 12, 2013) that it successfully performed GPS Military Code (M-Code) testing during a “live sky broadcast event” last month.
The IEC M-Code receiver is designed to provide improved accuracy, positioning, navigation and timing in conditions where the performance of current receivers might be compromised or unavailable.

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.
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.

Anyone who has gone to college is probably familiar with the idea of a capstone course. A final hurdle to clear in receiving a degree, students take such a course to demonstrate their practical knowledge by pulling together all of the main concepts taught throughout the program of study.

FIGURE 1: Potential components of a multisensor integrated navigation systemThe navigation world is booming with new ideas at the moment to meet some of the greatest positioning challenges of our times. To realize demanding applications — such as reliable pedestrian navigation, lane identification, and robustness against interference, jamming and spoofing — we need to bring these different ideas together.

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.

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.
