MD 2011 trajectory (NASA)A schoolbus-sized asteroid grazed the Earth’s atmosphere around 1:00 P.M. (EDT) on June 27. It was 7,600 miles (12,300 km) away at its closest point, at which time it veered away across the South Atlantic Ocean.
It actually passed through the GPS constellation, alerting us to the vulnerability of our vital PNT space vehicles. We can now add asteroids to the the list of GNSS collision risks that already includes other satellites and space debris.

An informal discussion at the 2010 symposium.The Symposium Gyro Technology has changed its name to Inertial Sensors and Systems because of the expanded focus and scientific topics covered at recent conferences. It will take place at the Karlsruhe Institute of Technology in Karlsruhe, Germany on September 21 and 21, 2011. The conference will be held in English.

IFEN’s SX-NSR Multi-Channel, Multi-GNSS ReceiverIFEN GmbH has begun shipping the first units of its new second-generation, multi-frequency and multi-GNSS software receiver — the SX-NSR.
The Poing, Germany–based company has also announced that the Galileo Test and Development Environment (GATE) facility that it instrumented and operates near Berchtesgaden for the German Space Agency (DLR) has been certified as a Galileo open-air test laboratory conforming to ISO 17025.

A new report by the American Meteorological Society (AMS) highlights the vulnerability of GPS-dependent critical infrastructures to disruptions caused by solar flares and other space weather events, and sets forth a series of recommendations for building robustness of the GPS service.
Entitled “Satellite Navigation & Space Weather: Understanding the Vulnerability & Building Resilience,” the report is based on a workshop organized by the AMS and held October 13–14, 2010 in Washington, D.C.

The U.S. Naval Observatory Alternate Master Clock at 2nd Space Operations Squadron, Schriever AFB in Colorado. This photo was taken in January, 2006 during the addition of a leap second. The USNO master clocks control GPS timing. They are accurate to within one second every 20 million years (Satellites are so picky! Humans, on the other hand, just want to know if we’re too late for lunch) USAF photo by A1C Jason Ridder.

1. DON’T BLAME GPS
Humboldt-Tolyabe National Forest, Nevada USA
√ In the Pacific Northwest, in-car navigators often indicate “short cuts” through wilderness mountains—with tragic results. One victim survived 49 days before rescue in May. (Reports blamed GPS – not digital maps or wireless communication.) GPS.GOV straightens out misperceptions, for those who need a guardian angel, but just get a signal.
Space geodesy and its applications for geosciences and space exploitation is the theme of the APSG 2011 workshop. It will be held at the RMIT University in Melbourne on June 23-25.

Uninterrupted continuous positioning technology is no longer a "nice to have" option but, for many applications, a "must have" requirement. Mobile devices increasingly rely on position/location functionality, and users have little tolerance for gaps in service.

Exhibit from the first Compass Satellite Navigation ConferenceThe second China Satellite Navigation conference will take place at Shanghai’s Expo Center on May 18-20, 2011.
The conference scientific chair is Prof. Sun Jiadong.
The aim of the conference is to build satellite navigation as an active academic field in China, to promote satellite system technology innovation and to strengthen the relationship between business and government for the advance of China’s Compass/Beidou system.
