The Radio Technical Commission for Maritime Services (RTCM) has completed a revision (Version 2.0) of its standard for Networked Transport of RTCM via Internet Protocol (Ntrip).
Designated as RTCM Standard 10410.1, Among other things, the new standard defined by RTCM’s Special Committee 104 (SC104) provides a protocol for streaming differential correction data or other kinds of Global Navigation Satellite System (GNSS) data to stationary or mobile users over the Internet.

GNSS manufacturer NovAtel Inc., of Calgary, Alberta, Canada, has received a new contract from the Federal Aviation Administration (FAA) to develop the next-generation GPS Wide Area Augmentation System (WAAS) reference receiver (the “GIII” receiver). The three-year contract is worth up to US$9.7million.

To say that enhanced Loran (eLoran) has been an on-again off-again program would give short shrift to multiple generations of official ambivalence about the proposed backup for GPS.
The latest chapter began on June 4 when Senator Maria Cantwell (D-Washington) introduced S. 1194, the Coast Guard Authorization Act for Fiscal Years 2010 and 2011 (FY2010/11).
Among other details, the measure directs the Secretary of Transportation to continue the Loran system until a plan has been drawn up and implemented to transition the program to eLoran.

A proposal now before the European Parliament and Council of the European Union would complete the transformation of the European GNSS Supervisory Authority (GSA) from the leading executive agency for the Galileo program into a diminished subsidiary of the European Commission (EC).
Inside GNSS • November/December 2008
Although satellite launch delays continue to plague the GPS program, planning and paperwork continue to make solid gains.
The U.S. Air Force announced that it will begin broadcasting a transitional civil navigation (CNAV) message on the GPS L2 civil signal (L2C). The signal is now being transmitted on the six IIR-M satellites in orbit as a dataless sequence without modulation. And, on October 31, 2008 the GPS Wing completed an integrated baseline review (IBR) of the GPS IIIA program.

Surrey Satellite Technology Limited (SSTL) will lead a British project to exploit signals from GPS and other GNSS satellites that are reflected from the Earth for remote sensing purposes.
The project will investigate a prototype instrument capable of measuring the roughness of the sea and soil moisture content, providing data for atmospheric science and for operational ocean and weather forecasting.
