EGNOS Capability Enhanced with Addition of New Generation of Satellite Transponders

On Saturday (March 22, 2014) two geostationary L-band transponders, GEO-2s, were successfully launched on board the SES ASTRA 5B satellite from the European Space Port in Kourou, French Guiana.

The new generation transponders will provide higher accuracy positioning signals to both civil and professional users of EGNOS-enabled receivers and ensure the continuity and quality of the European Geostationary Navigation Overlay Service (EGNOS) open service and safety-of-life services for the next 15 years, according to the European GNSS Agency (GSA).

New GNSS Signals

New GNSS Signals

A. J. Van Dierendonck

The world’s GNSS systems are entering a phase of transformation — modernization of existing systems (the U.S. Global Positioning System and Russia’s GLONASS) and development of new systems (China’s BeiDou and Europe’s Galileo) that benefit from the lessons learned from the original GNSSs.

Notable among the modernization initiatives is an interest in implementing new satellite signal designs. These include the GPS L5, L2C, and L1C signals as well as those signals designed for Galileo and BeiDou. GLONASS designers are also working on modernized signals.

Who’s Your Daddy?

In this article, we will take a look at the various GNSS signals from the perspective of their cost-benefit tradeoffs. First, we’ll look at the evolution of consumer GPS architecture to date — where acquisition speed and sensitivity have been the main drivers of receiver architecture. That architecture has evolved rapidly to take full advantage of the characteristics of the GPS C/A code.

Galileo Works!

Galileo Works!

The objective of the IOV phase was to launch the first four operational Galileo satellites and to deploy the first version of a completely new ground segment. During this phase, the European Space Agency (ESA) needed to validate — in the operational environment — all space, ground, and user components and their interfaces, prior to full system deployment. With the assistance of industry partners, ESA had to analyze the performance of the Galileo system and its components with the objective to refine the full operational capability (FOC) system.

E-GNSS for Road Transport: On Galileo’s Home Field

Road transport has always been a key sector for European GNSS, but safety- and security-related applications bring special challenges along with the opportunities. European Union (EU) officials speaking at a conference in Brussels last week explained why.

“Road transport is largest GNSS market opportunity,” said Gian-Gherardo Calini, head of market development at the European GNSS Agency (GSA). “This is 46.2 percent of the current GNSS market. Road transport is the key market.”

Galileo Leaders, Vision Coalesce at EU Space Policy Conference

Paul Weissenberg, deputy director-genreal, EC DG Enterprise

Last week’s Conference on EU Space Policy in Brussels — under the theme, “What direction for Europe in space between now and 2020?” — featured spirited calls for closer cooperation and the formation of a united front as Europe moves towards early Galileo services at the end of this year.

Falling somewhere between a team-building exercise and a love-fest, the amiable and optimistic sentiments expressed by European space leaders reflected a marked change of tone from those in recent months.

European GNSS Agency Invites Consultations on Technology Roadmap for Galileo PRS

[Updated Feb. 6, 2014] The European GNSS Agency (GSA) is inviting European industries and European Union (EU) Member State Competent Public Regulated Service (PRS) Authorities to share their views and ideas in support of the adoption of the PRS.

In particular, industries with potential interests and capabilities to support the development of Galileo PRS user segment technologies such as receivers, security modules, dedicated infrastructure, and market enablers are encouraged to join the discussion.

Speaking at his annual press conference in Paris last Friday (January 17, 2014), European Space Agency (ESA) Director General Jean-Jacques Dordain was cool, collected and, importantly, positive, as he laid out plans and parried questions on a whole range of ESA issues. From the Rosetta mission to manned space flights, Swarm, Gaia, Sentinel and Copernicus, and of course Galileo, he set the stage for an ambitious 2014.
