GPS Technology and People Behind Gravity Probe B's Einstein Relativity Experiment

NASA's May 3 announcement that its long-running Gravity Probe B (GP-B) mission had confirmed two key predictions derived from Albert Einstein's general theory of relativity, mentioned GPS autoland techniques as one of the projects spinoffs.

However, the involvement of GPS technology and GPS experts in the mission was much deeper than the passing reference in a press release.

But first, the news.

Air Traffic Control Modernization: FAA, NextGen, GNSS, and Avionics Equipage

» Air Traffic Control Modernization (PDF)

In between partisan confrontations around the 2011 federal budget and raising the U.S. debt limit, prospects are improving for federal legislation that would provide the Federal Aviation Administration (FAA) with a regular full-year budget for the first time since Fiscal Year 2007 — including support for completing the transition to a GNSS-driven air traffic control (ATC) system known as NextGen and a “public-private partnership” to equip aircraft with the needed avionics.
