GNSS+: PNT Heads for the Great Indoors

A confluence of technology, policy, and applications is turning indoor venues into the next big frontier for positioning and navigation.

Recent market studies have heralded the prospects for positioning, navigation, and tracking inside buildings where GNSS signals are often attenuated or blocked entirely. Many products and conceptual designs combine the indoor technologies with GNSS to provide “ubiquitous” positioning.

ICAO, RTCA Seek New Protections for GNSS Aviation Receivers

International aviation officials have asked U.S. experts to consider updating standards for GNSS aviation receivers to improve their ability to withstand interference from repeaters, pseudolites, and jammers.

Repeaters — generally used to extend navigation signals inside buildings where they would otherwise be blocked — rebroadcast GNSS satellite signals and therefore operate in the same frequency band. Although useful within a building, care must be taken to confined the repeater’s signal lest it confuse other receivers operating nearby.

Anatomy of a Rescue: the Galileo Satellites

Well, the good news is that the European GNSS program has recovered and stabilized the condition of its first two two full operational capability (FOC) satellites, which had been delivered into incorrect orbits following their August 22 launch.

Raytheon UK Announces Upgraded GPS Anti-Jam Technology

Raytheon UK launched a new enhanced version of its battlefield GPS L1/L2 anti-jam (GPS-AJ) capability, Landshield, this week (October 13–15) at the annual conference of the Association of the U.S. Army (AUSA 2014) in Washington, D.C.

A multi-element antenna with the anti-jam processing in a single small “one-box” form factor that interfaces at the RF level, Landshield is designed to enable GPS equipment to function unimpaired against a full range of hostile jammer types including narrow band, broadband, continuous wave, pulse, swept, and spectrally matched.

European Commission GSA Sign Agreement on Galileo Service Provision

The European GNSS Agency (GSA) and the European Commission (EC) have concluded an agreement that delegates a range of exploitation tasks for Galileo to the GSA, providing a framework and budget for the development of services and operations through 2021.

The signing of the Galileo Exploitation Delegation Agreement serves as an initial step towards the full Galileo Exploitation Phase.

UAVs at INTERGEO: Applanix, Others Announce GNSS-Guided Systems

Unmanned aerial vehicles (UAVs) are getting a lot of attention this week at the INTERGEO conference and exhibition in Berlin, Germany, where a special session on Tuesday (October 7, 2014), “UAVs in Practice,” focused on their use in airborne surveying and mapping, environmental monitoring, and other commercial or civil applications.

Arianespace Inquiry Identifies Source of Galileo Launch Anomaly; Next Attempt Could Come in December

In a report issued Tuesday (October 7, 2014), an Independent Inquiry Board formed to analyze the cause of the August 22 launch anomaly that placed two Galileo into the wrong orbits has concluded that frozen fuel lines caused a misfiring of attitude control thrusters on the launcher’s Fregat module.

According to the report, the problem can be remedied on the rockets in time for another launch in December, much sooner than some observers had speculated.
