IFEN Launches SX3 Software Receiver

IFEN SX3

IFEN introduced its new SX3 GNSS software receiver, a major upgrade of the company’s SX-NSR, last week at the ION GNSS+ conference in Tampa, Florida. Redesigned hardware frontends feature four wideband RF frequency bands that can be split into a maximum of eight sub-bands per unit. At the same time the bandwidth has been expanded to a full 55 megahertz, offering additional signal power especially in the Galileo E5 band.

ESA Outlines Efforts to Rescue Wayward Galileo Satellites

Orbits of the fifth and sixth Galileo satellites launched together on August 22, 2014, in red, compared to their intended position, in dashed green, and the position of the four IOV satellites launched in 2011 and 2012 in solid green. This view looks down over Earth’s South Pole, helping to illustrate how the two satellites’ orbital inclination relative to the equator is less than was intended ESA illustration.

The European Space Agency (ESA) released dramatic illustrations today (September 16, 2014) of the orbital locations of the two errant Galileo spacecraft launched on August 22, the intended orbit, and the locations of four In-Orbit Validation (IOV) satellites.

Air Force Weighs Switching to Multiyear GPS Procurements

Air Force Weighs Switching to Multiyear GPS Procurements

The Air Force says it might ask Congress for permission to implement bigger buys of GPS satellites beginning in fiscal year 2016 (FY16) once it sorts out whether to drop Lockheed Martin as the GPS III prime contractor and switch to a different manufacturer for the navigation payload.

The department told Congress in a recent report on multiyear procurement (MYP) that while its current approach “allows the government the flexibility to adapt to a changing budget profile and constellation needs, it prevents the program from realizing savings that MYP could provide.”

Digital Nav Payload Emerges as Factor in GPS III Re-Bid

Digital Nav Payload Emerges as Factor in GPS III Re-Bid

The advantages of a digital navigation payload, a technology singled out by both the House and Senate for $20 million worth of research support, appears to be a key factor in the Air Force’s search for a new GPS III contractor.

The digital payload “is a direct complement to the Production Readiness Alternate Sources Sought released in June,” Air Force officials said in an emailed response to questions about the technology and how it fits into the ongoing search for new GPS III suppliers.

As Galileo FOCs Near Launch, EC Holds Public Consultation on Open Service ICD

Installation of Galileo FOC satellite “Doresa” on the payload dispenser system. The first of two Galileo navigation satellites has been integrated on its payload dispenser system at Europe’s Spaceport in Kourou, French Guiana. The second satellite “Milena” was then installed in a side-by-side arrangement and will be mated atop a Soyuz Fregat upper stage. ESA/CNES/Arianespace/Optique Vidéo du CSG photo by P. Baudon

The European Commission (EC) has opened a public consultation on a newly revised version of the Galileo Open Service Signal in Space Interface Control Document (OS SIS ICD).
 
The consultation will take place through September 22, overlapping the scheduled first launch of fully operational capability (FOC) Galileo satellites on August 21. Details of the consultation process can be found on the EC Directorate-General for Enterprise website.

New Leaders at the GPS Helm

Washington, D.C., has a peculiarity of seasons. While most of the world marks the shifts between winter and spring, summer and autumn, the politicos on the streets of the U.S. capital count the passage of time in two-year increments.

New operatives and appointees flock to the centers of power in the early days of each administration and the opening of each Congress, then migrate to friendlier climes as congressional elections loom and the administration winds down — as it is now.
