Jules Verne Automatic Transfer Vehicle Guided to ISS by Thales Alenia GPS System

ATV Docking with International Space Station, NASA image

Europe’s Jules Verne Automatic Transfer Vehicle (ATV) that docked Thursday (April 3) at the International Space Station (ISS) is operating with a guidance, navigation control (GNC) system based on a GPS receiver developed by Thales Alenia Space Italia (TASI).

The GNC unit provides accurate position and velocity information for the ATV orbit control and rendezvous operation with the ISS. The Jules Verne completed its first space cargo voyage — 25 days long — docking the 10,470-kilogram (23,034-pound) ATV with the station, orbiting the Earth at 28,000 kilometers per hour.

According to the European Space Agency (ESA), this docking marks the beginning of Jules Verne’s main servicing mission to deliver cargo, propellant, water, oxygen and propulsion capacity to the station, as well as ESA’s entry into the restricted club of the partners able to access the orbital facility by their own means.

Ivanov GLONASS Flap Obscures Program Reality

Russian Deputy Prime Minister Sergey Ivanov’s criticism of Roscosmos and GLONASS continues to ripple in news columns around the world.
Widely reported in Russian media and picked up and amplified in derivative reports, Ivanov’s complaints focused on GLONASS’s relative inaccuracy, limited coverage, and lack of user equipment.

However, aside from the fact that the person making the remarks was Ivanov — a powerful figure once thought to be in line to succeed Russia’s President Vladimir Putin, none of this is really news. Rather, it seems like another example of the phenomenon that, when people learn of something for the first time, they assume it has just happened.
