South Korea Relaunches Its eLoran Program

After a delay to reformulate the system design, South Korea is moving ahead to implement a national enhanced Loran (eLoran) system to provide uninterrupted positioning, navigation, and timing (PNT) services in the wake of GPS jamming by North Korea.

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’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.

DoD Seeks Sources for 50,000 eLoran Receivers

In a nod to the usefulness of international enhanced Loran (eLoran) systems the U.S. Department OF Defense (DoD) in January began a search for companies able to supply some 50,000 eLoran receivers. Meanwhile a multi-agency team continues sketching out the structure of a potential U.S. eLoran system for federal officials weighing a relaunch of the program as a backup to GPS.

RTCA Begins Standards Work on Quartet of New GNSS-Related Aviation Devices

The group that sets standards for aircraft navigation receivers is planning work on four new types of devices including the first multi-signal and multi-constellation aviation receivers and a more cost effective navigation system to help planes traverse GPS-impaired areas.

Financial Networks Shifting to GPS-Stamped Precise Time

New competitive demands and regulatory requirements are driving financial firms around the world to use highly precise timestamps on incoming information and transactions, a trend likely to push firms to adopt a common time source like GPS.

Study Launched to Quantify the Economic Benefits of GPS

A new study is underway to estimate the economic benefit of GPS and quantify what’s at stake if anything interferes with its navigation signals.

Launched at the request of the National Executive Committee (ExCom) for Space-Based Positioning, Navigation, and Timing (PNT), the first segment of the two-part study would look at major uses of GPS. It will estimate the benefits derived from the system and describe the costs that would be incurred if GPS became unavailable, compiling the results in an interim report.

NASA’s Ikhana UAS Captures Orion Splashdown

As NASA’s new exploration spacecraft Orion made its way back to Earth from its first test mission, the Ikhana unmanned aircraft system captured its return—making it possible for NASA to stream the parachute deployment and splashdown footage on live television.

Raytheon, Lockheed Complete Another GPS III, OCX Development Exercise

On Wednesday (December 17, 2014) Raytheon Company announced successful completion of the fourth of five planned launch and early orbit exercises being undertaken together with Lockheed Martin to demonstrate new automation capabilities, information assurance, and launch readiness of the U.S. Air Force's next generation GPS III satellite and Operational Control System (OCX).

Errant Galileo FOC Satellite Signal Helps Provide First Positioning

Galileo's fifth satellite (and first fully operational capability, or FOC, spacecraft) — recently salvaged from an incorrect orbit  — has been combined with three predecessors to provide its very first position fix.

Test receivers at the European Space Agency (ESA) ESTEC technical center in Noordwijk, the Netherlands, and at the Galileo In-Orbit Test station at Redu, Belgium, received the signals at 12:48 GMT on December 9 from a quartet of Galileo satellites and fixed their horizontal positions to better than two meters.
