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.

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.
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.

A series of ABI Research studies released in recent months sketches a promising future of robust growth in GNSS OEM markets.
The London- and New York–based company’s 2014 GNSS IC vendor matrix released today (June 30, 2014) concluded that Qualcomm is the leading GPS IC vendor, followed by Broadcom, and — for the first time — MediaTek in third place after another year of strong growth and robust shipments as a result of its targeted design strategy.

Trimble announced today (June 26, 2014) that registration is officially open for its International User Conference — Trimble Dimensions — being held November 3–5 at the Mirage and the Treasure Island hotels in Las Vegas, Nevada.
The conference focuses on innovations and applications of navigation, positioning, and information technologies in agriculture, construction, civil infrastructure, engineering, government, mapping, natural resources, surveying, telecommunications, transportation & logistics, and utilities.
GPS and GLONASS emerged from the depths of the Cold War to become the world’s leading dual-use (civil/military) GNSS programs in the post-Soviet era.
Now renewed tensions between their national sponsors, the United States and Russia, are undercutting a decade-long move toward GNSS cooperation.
The United States and Russia initiated bilateral GNSS cooperation in December 2004, with the primary goal of enabling civil interoperability at the user level between GPS and GLONASS. In June 2012 the two nations issued a renewed statement of cooperation in GNSS.

Scott Pace. GWU photoLeading navigation experts are worried an upcoming workshop on GPS receivers being organized by the Federal Communications Commission (FCC) is an attempt to initiate design mandates for user equipment that could potentially undermine the GNSS community.
“There is currently planned an FCC workshop that is going to, among other things, address certification and standards for receivers,” said Brad Parkinson, the acting chair of the National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board and a former chief of the NAVSTAR GPS Joint Program Office.
