Raytheon Company reached several milestones recently in its development of the GPS Next -Generation Operational Control System (GPS OCX). Lockheed Martin’s GPS III Non-flight Satellite Testbed (GNST) — a full-sized, functional satellite prototype currently residing at Cape Canaveral Air Force Station — successfully established remote connectivity and communicated with OCX during pre-flight tests. GNST proved that it could connect with... read more

Europe Tests Galileo Public Regulated Service

September 30, 2013By
Fire_engine_galileo

European Union member states began their independent testing of the Public Regulated Service (PRS) broadcast by the four Galileo navigation satellites in orbit. Transmitted on two frequency bands with enhanced protection, PRS offers a highly accurate positioning and timing service, with access strictly restricted to authorized users, such as government defense, security, and emergency services. PRS access was initially considered... read more

The System: IRNSS Signal Close up

September 1, 2013By and

IRNSS Signal Close up By Richard Langley, Steffen Thoelert, and Michael Meurer The spectrum of signals from IRNSS-1A, the first satellite in the Indian Regional Navigation Satellite System, as recorded by German Aerospace Center researchers in late July, appears to be consistent with a combination of BPSK(1) and BOC(5,2) modulation. Figure 1 shows that, centered at 1176.45 MHz, the signal... read more

Future positioning and navigation applications of modernizing and newly established GNSSs will require a higher degree of signal accuracy and precision. Thus, rigorous and detailed analysis of the signal quality of recently launched satellites, including the discovery of any possible imperfections in their performance, will have important implications for future users. read more

Norwegian Company Gives Galileo Its Voice

The last three Search and Rescue Transponders (SARTs), left, and the last two Frequency Generator and Upconverter Units (FGUUs), right, units produced by Kongsberg Norspace under the first work order for the first 14 Galileo Full Operational Configuration (FOC) satellites being prepared for shipment to Surrey Satellite Technology Ltd, seen together with some of the key project team members.

A trans-European production line is progressively transforming the Galileo satnav system into a working reality, according to the European Space Agency (ESA). The 22 satellites so far contracted to join the four already in orbit are having their payloads manufactured at Surrey Satellite Technology Ltd. in the UK, which are then integrated to their satellite platforms at OHB in Germany.... read more

Courtesy of the European Space Agency There might seem to be a hole in the side of this Galileo satellite — in fact its folded solar wings are simply reflecting a noise horn in the wall, about to recreate the deafening roar of a rocket lifting off. Anyone witnessing a rocket launch will be struck by the noise levels, even... read more
