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

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.

GPS Budget Cut by Nearly $100 Million as White House Pares GPS III Funds

The White House showed continuing support for the GPS program with a budget request that was, with one key exception, comparable to that of previous years. That exception though, a cut to GPS III procurement including the zeroing out of advance procurement monies, resulted in an overall program reductions of roughly $100 million.

Implementation of a Future Leap Second in Nav Message Causes Problems for Some GPS Receivers

The U.S. Coast Guard Navigation Center (NAVCEN) has issued an alert today (February 2, 2015) regarding problems with some brands and models of GPS receivers as the result of inclusion of information about a future leap second.

GPS Policy Outlook: What to Watch for in the New Congress

Three threads of legislation running through the new congressional session —location privacy, critical infrastructure protection, and updates to the Communications Act — are worth careful monitoring by the GPS community. One bill in particular, the Terrorism Prevention and Critical Infrastructure Protection Act of 2015, could expand the definition of critical infrastructure to include the GPS system — something GNSS experts have been advocating for several years.

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.

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.
