Global Navigation Satellite Systems Engineering, Policy, and Design
Russia’s involvement in the Ukraine crisis has turned much of public opinion in the West against that country, in particular souring the relationship between the European Union (EU) and Russia. And, while the ceasefire signed in September technically is still in force, the EU-Russia rift is far from smoothed over.

Implementation of code-Phase structures for GLONASS signals ?/?, L2C and L3Topcon Positioning Group has announced that its latest GNSS reference receiver has tracked a new signal from the GLONASS constellation.
The GLONASS-M 55 satellite was launched in June and is equipped
with an experimental payload capable of transmitting CDMA signals in the
Russian GNSS system’s L3 frequency band centered at 1202.025 MHz. According to the company, Topcon engineers successfully tracked the signal using the NET-G5
receiver during a series of recent tests at the Topcon Technology Center
in Moscow, Russia.
The European Space Agency (ESA) announced plans today (November 10, 2014) to implement a series of maneuvers to reposition one of two Galileo full operational capability (FOC) satellites left in the wrong orbit this summer, as a prelude to its health being confirmed.
The aim is to raise the lowest point of the satellite’s orbit — its perigee — to reduce the radiation exposure from the Van Allen radiation belts surrounding Earth, as well as to put it into a more useful orbit for navigation purposes.
Technology to counter the threat of GNSS jamming is now available at Dover and along the east coast of the United Kingdom as the island nation continues to implement an enhanced Loran (eLoran) system that is setting an example for the world.

The European Satellite Navigation Competition (ESNC) has gone Big Time.
Unlike past years, when product designers and engineers from small- and medium-sized enterprises (SME) have walked away with the top prize, this year’s overall winner was Airbus Defence & Space (Airbus DS GmbH), a division of the Airbus Group (formerly EADS). Headquartered in France and generating annual revenues of €14 billion, Airbus DS was established last year by the merger of the parent company’s Airbus Military, Astrium, and Cassidian units.

Daniel Calleja Crespo, Director-General of DG Enterprise. EC photoThe European Parliament voted yesterday (October 22, 2014) to accept President-elect Jean-Claude Juncker’s “last-chance” leadership for the European Commission (EC).
But the 11th-hour reshuffling of posts appears to leave Galileo without a clear-cut leader, at least at the political level — even as the Commission and its European Space Agency (ESA) partner have decided to give up the prospect of a December launch of two satellites.

The IGNSS 2015 symposium on GPS/GNSS and industry exhibition will take place at the Outrigger Hotel in Gold Coast, Queensland, Australia from July 16 to 18, 2015. The conference venue is one block from the famous Surfer’s Paradise Beach.
The deadline for abstracts is February 9, 2015.
Registration will be open at the end of March, 2015. Early bird registration ends May 18, 2015.

A confluence of technology, policy, and applications is turning indoor venues into the next big frontier for positioning and navigation.
Recent market studies have heralded the prospects for positioning, navigation, and tracking inside buildings where GNSS signals are often attenuated or blocked entirely. Many products and conceptual designs combine the indoor technologies with GNSS to provide “ubiquitous” positioning.

GPS pseudolite used in experiment at University of New South Wales Satellite Navigation and Positioning LabInternational aviation officials have asked U.S. experts to consider updating standards for GNSS aviation receivers to improve their ability to withstand interference from repeaters, pseudolites, and jammers.
Repeaters — generally used to extend navigation signals inside buildings where they would otherwise be blocked — rebroadcast GNSS satellite signals and therefore operate in the same frequency band. Although useful within a building, care must be taken to confined the repeater’s signal lest it confuse other receivers operating nearby.

Well, the good news is that the European GNSS program has recovered and stabilized the condition of its first two two full operational capability (FOC) satellites, which had been delivered into incorrect orbits following their August 22 launch.

GSA Executive Director Carlo des DoridesThe European GNSS Agency (GSA) and the European Commission (EC) have concluded an agreement that delegates a range of exploitation tasks for Galileo to the GSA, providing a framework and budget for the development of services and operations through 2021.
The signing of the Galileo Exploitation Delegation Agreement serves as an initial step towards the full Galileo Exploitation Phase.

Unmanned aerial vehicles (UAVs) are getting a lot of attention this week at the INTERGEO conference and exhibition in Berlin, Germany, where a special session on Tuesday (October 7, 2014), “UAVs in Practice,” focused on their use in airborne surveying and mapping, environmental monitoring, and other commercial or civil applications.

In a report issued Tuesday (October 7, 2014), an Independent Inquiry Board formed to analyze the cause of the August 22 launch anomaly that placed two Galileo into the wrong orbits has concluded that frozen fuel lines caused a misfiring of attitude control thrusters on the launcher’s Fregat module.
According to the report, the problem can be remedied on the rockets in time for another launch in December, much sooner than some observers had speculated.
