TABLE 1: Deployment Status Note: Two types of clocks on board: PHM = Passive Hydrogen Maser, RAFS = Rubidium Atomic Frequency StandardEurope’s new age of satellite navigation has passed a historic milestone — the very first determina-tion of a ground location using the four Galileo satellites currently in orbit together with their ground facilities.
This fundamental step confirms the Galileo system works as planned.

One of my fond memories as a boy growing up in rural northeastern Oregon is sitting on an apple box in the basement of our house reading back issues of National Geographic.
All those wonderful color photos. And the maps, with their little illustrated explanations of Roman ruins in England or Babylonian irrigation practices in the Fertile Crescent!

eCall is the European Union (EU) initiative aimed at reducing road casualties by increasing the speed and efficiency of emergency response. It involves a device installed in cars that will automatically dial the EU’s “112” emergency phone number in the event of a serious road accident.
Key data including time, date, and GNSS coordinates will be sent to the Public Safety Answering Point (PSAP) and then relayed to the most appropriate emergency service. The eCall is triggered by airbag deployment and impact sensor information.

It’s spring and privacy proposals are popping up in abundance, threatening to complicate the lives of law enforcement officers, spoil the landscape for some location-based businesses, and choke off the U.S. market for commercial unmanned aerial systems (UAS) before it gets off the ground.

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.
