Russia has plans to launch four more satellites for the Global Navigation Satellite System (Glonass) by this year-end, the Aerospace Defence Forces head said, as the website Zeenews reported.
“Three GLONASS satellites are scheduled to be launched on board of a Proton carrier rocket in July from the Baikonur space centre and another one is planned to be launched in December from the Plesetsk space centre,” Maj. Gen. Alexander Golovko said.
The European satellite navigation mission Galileo marked a new success: On 25 April 2013, all four Galileo satellites started working as clocks accurate to a few billionths of a second, disseminating the exact time through their signals expressed as the UTC Universal Coordinated Time global standard.

The theme of ISGNSS 2013 is "Connecting Continents through GNSS where Europe and Asia Meet." It will be held from October 22 through 25 at the Congress Center in Yildiz Technical University of Istanbul. The first conference in this series was held in 1999 in Japan. The ISGNSS International Program Committee is headed by Prof. Sang Jeong Lee of Korea's Chungnam National University.
Online registration begins May 1, 2013. Abstracts will be accepted through July 21, 2013 on the following topics:
Satellite navigation systems are based on the highly precise measurement of time. A receiver on the ground pinpoints their positions by calculating how long signals from satellites in orbit take to reach it.
The United States and United Kingdom announced on January 17, 2013 that the British government would end efforts to obtain patent or intellectual property (IP) rights related to GPS, as InsideGNSS reported.
Europe’s third Galileo satellite has transmitted its first test navigation signals back to Earth. The two Galileo satellites launched last October have reached their final orbital position and are in the midst of testing.
ESA has introduced its own wiki-based information source, Navipedia, which is also the first ever ESA technical wiki opened to the public. Anyone can comment, propose modification to an existing article, suggest a new topic or submit a draft article. There are more than 400 articles on the site to date covering the fundamental principles of
With the first two Galileo In-Orbit Verification (IOV) satellites already in orbit, the European Space Agency (ESA) is currently pondering whether or not the spacecraft could also be used to manage distress calls and other types of
