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.

u-blox Launches GPS Timing Module

u-blox LEA-5T

Swiss GNSS chip manufacturer u-blox has introduced a new precise timing GPS module, the LEA-5T, precise timing at the CTIA Wireless 2008 conference taking place this week in Las Vegas.

Based on the company’s 50-channel, fifth-generation chipset technology, the LEA-5T is intended for such applications as telecom network synchronization, use in WiMAX base stations for home-based broadband networks, and data communication among geographically dispersed systems and devices such as NTP servers.

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.

Fastrax Launches Two New OEM GPS Units

IT321

Fastrax Ltd. has launched two new GPS OEM receivers, including one with an integrated chip antenna, aimed at designers of mass-market automotive and portable devices.

The Fastrax UC322 incorporates an on-board chip antenna (five millimeters thick) designed to reduce the size from that of typical patch antennas and large separate ground planes, according to the company. Instead, the end device’s printed circuit board functions as part of the antenna.

Russia’s Home-Grown GLONASS-GPS Receiver

What may be the first domestically produced, consumer-oriented GLONASS-GPS receiver, sold out shortly after their introduction in Russia’s Ion retail stores.

The Glospace SGK-70 features a 12-channel GLONASS receiver and a 20-channel GPS receiver, which can reportedly use either or both systems simultaneously. Designed primarily for in-vehicle use, the 7.4×4.7×1.2-inch unit incorporates Samsung components has an SD/MMC slot and comes with a 512MB card that includes detailed maps of the Moscow area.
