Recently released views of the next two Galileo satellites in the European Space Agency’s testing lab, along with dual-launch rumblings from the U.S. Air Force and Lockheed Martin, occasion this story about two birds with one drone. That is, an unmanned autonomous vehicle bound for the exosphere. The rest of the GNSS world is on board with this topic; isn’t... read more

GPS OCX Ground Control in GAO Report

May 30, 2013By
The next-generation GPS ground-control system, known as OCX.

A March 2013 report from the Government Accountability Office (GAO) seems to claim that the projected cost of the next-generation GPS ground-control system, known as OCX, increased by 43 percent, or $1 billion over the past year, to a total cost estimate of $3.7 billion. As GPS World contributing editor Don Jewell wrote shortly after the GAO release, “In fact,... read more

Time to Hit Warp Speed, Galileo

April 23, 2013By

Report from ENC: Constellation Needs 22 Satellites in Three Years Launch, deploy, and operate “22 satellites in less than 3 years.” That’s two satellites every three months, leading to a four-at-once launch in 2014. And that’s the challenge that Europe and the European Space Agency (ESA) now face. This pointed call to action during the opening plenary of the European... read more

It’s been a long time coming. With the capability to make a position fix from four signal-broadcasting satellites, we can now say that Galileo has truly arrived. Of course, this is only one of many milestones (excuse me, kilometer markers) along the way, a trajectory that could be bounded at 23 years and counting, or possibly longer. Let’s not forget,... read more

Expert Advice: Setting Standards for Indoor Position

April 1, 2013By

Communications Security, Reliability, and Interoperability Council (CSRIC) Update By Greg Turetsky Many of us remember way back in 2001 when the FCC first announced E911 position reporting requirements for cell phones. That was a long time ago in many significant ways. Everyone had 2G phones and anxiously anticipated the arrival of 3G, and with it, data. Most people still had... read more

It’s an interesting and perhaps unanswerable question, whether governments ever truly listen to the voice of the people, and act accordingly. That premise gets another test in a GNSS setting, in Hawaii next month. An April 26 full-day session of the International Committee on GNSS (ICG) Interoperability Workshop will give those who design and build GNSS receivers a forum to... read more
