Extra Life for IIRs, IIR-Ms

August 29, 2013By

U.S. Air Force engineers are testing on-orbit a technique to extend the life of the 19 GPS IIR and IIR-M satellites on orbit, roughly 60 percent of the current constellation. A new charging method may reduce the rate of satellite battery degradation, thereby extending satellite operational life. If the technique passes the test, the initiative could add a combined 20... read more

Looking High in the Sky from Down Under

August 29, 2013By

A few months ago I wrote in the magazine’s Out in Front column about the surprising abundance of BeiDou-centric papers to be presented at the upcoming ION GNSS+ conference, to which I very much look forward — both the abundance and the conference as a whole. With GLONASS encountering stormy weather of late, and Galileo plugging steadily along but not... read more

Norwegian Company Gives Galileo Its Voice

August 26, 2013By
Galileo hardware ready for delivery. 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

The System: IRNSS Success, GLONASS Bellyflop

August 1, 2013By

IRNSS Success The Indian Regional Navigation Satellite System (IRNSS) successfully launched its first satellite on July 1 from the Satish Dhawan Space Centre at Sriharikota spaceport on the Bay of Bengal. An Indian-built Polar Satellite Launch Vehicle PSLV-C22, XL version, carried the 1,425-kg satellite aloft. IRNSS-1A is the first of seven satellites that will make up the new constellation: four satellites... read more
