Four Galileo ‘topped off’ for November launch

October 24, 2016By

Fueling operations have begun with the four Galileo spacecraft to be launched Nov. 17 from French Guiana. This will be launch contractor Arianespace’s first launch using its Ariane 5 rocket to deploy Europe’s constellation of navigation satellites. The fueling activity is now underway in the Spaceport’s S3B payload preparation facility. One of the first to be processed is named “Antonianna,” after an Italian child... read more

Galileo Initial Services looming

September 26, 2016By

With Galileo Initial Services at last on the horizon and a quadruple satellite launch scheduled for November, here’s hoping that Europe’s GNSS constellation will be delivering limited, but reliable, global PNT services before the year is out. The four Galileo satellites for Arianespace’s first Ariane 5 mission for the constellation are being prepared at ESA’s launch facility in French Guiana.... read more

September 9, 2016By

A transatlantic flight delivered four Galileo satellites to French Guiana on Tuesday, in preparation for a shared launch this November by Ariane 5 — the first for Europe’s satnav constellation. read more

System of Systems: Galileo birds active, faulty launch victims still viable

August 23, 2016By
Galileo orbits viewed from above.

Galileo birds active Faulty launch victims still viable Europe’s fifth and sixth Galileo satellites, salvaged from their faulty 2014 Soyuz launch, will begin broadcasting working navigation signals for test purposes, for the benefit of receiver manufacturers, service providers and scientific researchers. The European Commission will decide later whether the two satellites will become part of the operational Galileo constellation. The... read more

US Air Force releases GPS III-3 launch services RFP

August 4, 2016By

The Air Force has released a Request for Proposal (RFP) for launch services for the GPS III-3 mission, scheduled to launch in 2019. Proposals are due Sept. 19; the contract will be a standalone contract for a single GPS III launch. The United Launch Alliance (ULA) and SpaceX are expected to compete for the contract. In April, SpaceX was chosen to launch the... read more

Air Force jam-proof test range ready; Galileo teendom

Locatalite transceiver installation in the White Sands Missile Range Ultra High-Accuracy Reference System, provided by the U.S. Air Force for testing equipment under conditions of GPS jamming.

Provides high-accuracy PNT even when GNSS jammed A critical capability to predict for GNSS chips and receivers —and for devices using alternative or back-up PNT technologies — is how they will actually perform without GPS. Filling this need, the U.S. Air Force 746th Test Squadron has declared Initial Operational Capability (IOC) for its new truth reference, the Ultra High-Accuracy Reference... read more

User location data could support satellite launches

June 23, 2016By

Let’s look through the other end of the telescope this month. The satellites are nattering along, lining up in orderly fashion at the rocket pad, extending their solar arms smoothly in space once they arrive on orbit. The constellations accrue and new signals inch closer to maturity. The only blips on the horizon come from Ligado’s terrestrial impulse and a... read more
