GATE Galileo Testbed Achieves Re-Certification

Berchtesgaden, Germany

The Galileo Test and Development Environment (GATE), located near Berchtesgaden in southern Bavaria, Germany, has been recertified for operation, extending the operational life of the facility through January 2016, according to its operator, IFEN GmbH

GATE enables companies and research organizations to use the testbed for various experiments, taking advantage of the eight ground transmitters emitting the Galileo signals towards the 25-square-kilometer core test area.

DoT Sets Another GPS/GNSS Workshop on Adjacent Band Compatibility, Receiver Testing

DoT Sets Another GPS/GNSS Workshop on Adjacent Band Compatibility, Receiver Testing

A Federal Register notice published today (February 13, 2015) announced a third U.S. Department of Transportation workshop on March 12 to continue discussions of the Global Positioning System (GPS) Adjacent Band Compatibility Assessment Plan.

The workshop will focus on identification of GPS and GNSS receivers to be considered for testing that are representative of the current categories of user applications and discuss a GPS/GNSS receiver test plan.

Galileo Satellites Reach French Guiana for March Launch

Two more Galileo full operational capability (FOC) satellites have reached French Guiana in preparation for a late-March launch from the European spaceport there.
 
The seventh and eighth Galileo satellites — the third and fourth FOC spacecraft — will be launched together by Soyuz during last week of March, following the European Commission’s endorsement of the resumption of Galileo launches that had been interrupted after the previous Soyuz launch last August placed satellites into the wrong orbit.

New Trimble GNSS Product Upgrades Consumer Devices for Professional Applications

New Trimble GNSS Product Upgrades Consumer Devices for Professional Applications

Trimble introduced today (February 10, 2015) the R1 GNSS receiver, a pocket-sized, standalone, single-frequency (L1/G1) receiver that works with iOS, Android or Window mobile handhelds, smart phones, and tablets using Bluetooth connectivity.
 
When paired with a smart device, the receiver/antenna combination adds GNSS geo-location capabilities to transform consumer devices into high-accuracy mobile data collection systems. The 44–parallel channel receiver can track GPS, GLONASS, Galileo, BeiDou, and Quasi-Zenith Satellite System (QZSS) signals.

ICAO Recommends New Flight-Tracking Performance Standard

ICAO Recommends New Flight-Tracking Performance Standard

Member states of the International Civil Aviation Organization (ICAO) recommended the adoption of a new 15-minute aircraft tracking standard yesterday (February 3, 2015) during discussions among more than 850 participants to the UN aviation body’s 2015 High Level Safety Conference in Montreal, Canada.

The recommended standard is performance-based and not prescriptive, meaning that global airlines would be able to meet it using the available and planned technologies and procedures they deem suitable.

ESA’s GNSS Year in (P)review

A year ago, European Space Agency Director General Jean-Jacques Dordain said ESA would launch six new Galileo satellites into orbit in 2014, making 10 fully functional satellites in orbit and allowing the European GNSS Agency (GSA) to launch its much-awaited Galileo early services.
 
Instead, only two satellites were launched in 2014, and those into the wrong orbits. At his year-ahead press conference in Paris on January 16, Dordain explained what went wrong and what we can expect in 2015.

Galileo Upgrade Will Cause Temporary Decline in Service

Galileo Upgrade Will Cause Temporary Decline in Service

Galileo Sensor Stations (GSSs) pick up Galileo signals in space (SIS) to perform clock synchronisation and orbit measurements which are fed back to the twin Galileo Control Centres to serve as the basis of the navigation message incorporating clock and position corrections and associated integrity data. Uplink Stations (ULSs) then uplink this navigation message to the Galileo satellite navigation payloads for rebroadcast to users. Telemetry, Tracking and Command Stations (TT&Cs) provide the link between the Control Centres and the satellite platforms. ESA figure

Galileo’s operation controllers will temporarily stop updating satellite orbital positions in the system’s navigation messages beginning near the end of this month in order to help implement upgrades in the ground mission segment, the European Space Agency (ESA) announced today (January 19, 2015).

Although the Galileo satellites will continue to transmit navigation signals, the generation and uplink of updated navigation messages will be interrupted during the last week of January for about five weeks.

The Party Crashers

The Party Crashers

These days getting the United States, Russia, China, and Europe to agree on a common policy seems to be an increasingly rare event.

That’s why the long-standing comity among system operators in the GNSS sphere is particularly notable and welcome. “Interoperable and compatible” is the first principle espoused by the four nations under the aegis of the International Committee on GNSS.

Trimble Launches Timing Portfolio for Mobile Telecom

ICM SMT 360 timing module

Trimble has introduced a new portfolio of GNSS-based time and frequency products to address the synchronization needs of the fast-growing 4G LTE (Long Term Evolution) small-cell telecom market.

Mobile telecom networks, whether 3G, 4G LTE, LTE-Advanced (LTE-A) wireless technologies, or a combination, need high-precision synchronization and syntonization.

From Data Schemes to Supersonic Codes

A decade has passed since the first GNSS system-level authentication protocols were proposed, and yet the current ongoing discussion is still, “Do we really need GNSS signal authentication?” Indeed, the current argument is whether we need authentication at the system level (the satellite broadcast service) or whether user-based authentication (anti-spoofing) is sufficient for a number of application requirements.
