A Model-Based Approach

For the complete story, including figures, graphs, and images, please download the PDF of the article, above.

Galileo receiver designers require formal interface specifications for the Galileo signal-in-space (SIS) in order to write unambiguous and accurate specifications for Galileo receivers. To compute their positions, Galileo receivers must be able to retrieve timing and orbital information from the data stream conveyed in Galileo analog signals.

Europe's Galileo Reaches Many 2010 Milestones - but Satellite Launches Still Delayed

Europe’s Galileo space-based navigation system still awaits launch of its first in-orbit validation (IOV) satellites — now set for August 2011 — but the program is rolling out a steady stream of announcements of milestones reached.

Most recently, European Commission (EC) and European Space Agency (ESA) officials inaugurated the Fucino Galileo Control Center, 130 kilometers (81 miles) east of Rome, which will be responsible for the Ground Mission Segment.

GMV Will Launch Fully Hosted Software GPS Receiver at Mobile World Congress

GMV will launch the SRX-10, a software GPS receiver for mass-market applications, at this year’s GSMA Mobile World Congress, scheduled February 14–17 in Barcelona, Spain.

As a fully hosted solution, all SRX-10 receiver functions — even signal acquisition and tracking — can be hosted on a general purpose CPU with only the requirement of adding on a low cost RF front-end, according to the company.
The company cites other benefits offered by its new software receiver, particularly its substantial flexibility and upgradeability.

Galileo GNSS Pushes Through European Budget Shortfalls, EGNOS Back on Track

Amid continuing debate over how to handle budgetary shortfalls in building a European GNSS, the European Space Agency (ESA) signed a €194 million ($270.5 million) contract on October 25 with SpaceOpal to provide space- and ground-based services to operate the Galileo constellation once it has been fully deployed.
