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

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

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

News from the European Space Agency (ESA) Following rigorous testing in France and Germany, a new type of dispenser designed to carry four navigation satellites into orbit at once is now in French Guiana, in place for Galileo’s first Ariane 5 launch later this year. The dispenser is an essential element of launch success, with a double role to play.... read more

GLONASS launches No. 53 to replenish constellation

May 31, 2016By

On May 29 a Soyuz-2.1b with upper stage Fregat and a GLONASS-M satellite (No. 53) successfully lifted off from Plesetsk Space Center. The satellite was placed into its preprogrammed orbit and registered by the facilities of the Titov Main Test and Space Systems Control Centre. Ground control established communications with it. The stable telemetry link shows that onboard satellite systems... read more
