Global Navigation Satellite Systems Engineering, Policy, and Design
A reported White House plan to rely on voluntary adoption of privacy best practices for unmanned aircraft operations appears unlikely to address concerns that the aerial vehicles will be used to spy on people in their homes or abused by law enforcement officials conducting surveillance.
The Global Positioning Systems (GPS) Directorate will host an open public forum on August 22 for the following NAVSTAR GPS public documents: IS-GPS-200 (Navigation User Interfaces), IS-GPS-705 (User Segment L5 Interfaces), IS-GPS-800 (User Segment L1C Interface), and ICD-GPS-870 (Navstar Next Generation GPS Operational Control Segment [OCX] to User Support Community Interfaces).

The USNO master clocks control GPS timing. They are accurate to within one second every 20 million years (Satellites are so picky!

1. SMART BALL
Portland, Oregon USA
√ Adidas has designed every official World Cup ball since 1970. And that’s not all! The Adidas Innovation Team in Portland, Oregon, spent 4 years on a smart soccer ball with a “six-axis MEMS accelerometer sensor package” that can detect speed, spin, strike and flight path data and whip it on over to the special GPS app on your iPhone. The app interprets the data for you, coaches you, and keeps a video to show your friends. On sale now for only $299.
Ken Hudnut, U.S. Geological SurveyFor at least two decades, GPS experts, geodesists, and public agencies have been working together to develop high-accuracy, large-scale continuously operating GPS reference stations that provide them the capability to monitor and model crustal deformation, tectonic plate movement, and the effects of geohazards such as earthquakes and volcanic eruptions.
Now, GNSS-augmented advance warning systems are going into place that can give us a crucial margin of safety in the event of an earthquake.
And none too soon.

Washington, D.C., has a peculiarity of seasons. While most of the world marks the shifts between winter and spring, summer and autumn, the politicos on the streets of the U.S. capital count the passage of time in two-year increments.
New operatives and appointees flock to the centers of power in the early days of each administration and the opening of each Congress, then migrate to friendlier climes as congressional elections loom and the administration winds down — as it is now.

Q: How do measurement errors propagate into GNSS position estimates?
A: Not surprisingly, GNSS positioning accuracy is largely dependent on the level of measurement errors induced by orbital inaccuracies, atmospheric effects, multipath, and noise. This article discusses how, specifically, these errors manifest as position errors.

Equation 1The small satellite “Technologie-Erprobungs-Träger 1” (TET-1) is the first spacecraft developed for the German Aerospace Center (DLR) On-Orbit-Verification (OOV) program, which provides flight opportunities dedicated to testing and qualification of new technologies in space. The satellite was lifted into a low-Earth orbit (LEO) on July 22, 2012, from the launch site in Baikonur, Kazakhstan.
