eLoran Appears Doomed Despite Possible GPS Backup Role

Enhanced Loran (eLoran), the proposed backup to GPS that has made a career out of surviving efforts to eliminate its Loran-C foundation, now appears to be only two signatures away from extinction — and both appear likely.

A House-Senate conference committee version of the fiscal year 2010 (FY10) appropriations bill for the Department of Homeland Security (DHS) approved October 7 allows for termination of the Loran-C signal on January 4, 2010.

Europe Declares Start of EGNOS Satellite Navigation Service

Antonio Tajani, EC Vice-President for Transport Policy, announces EGNOS Open Service.

During a press conference today (October 1, 2009), Antonio Tajani, European Commission vice-president for transport policy, announced the official start of operations for EGNOS, the European Geostationary Navigation Overlay Service.   This is a major milestone for EGNOS, a satellite-based augmentation system that improves the accuracy of satellite navigation signals over Europe.

The EGNOS Open Service is now available free of charge for non-safety-of-live applications to all users equipped with suitable receivers – and most mass-market satellite navigation receivers being sold today are EGNOS-ready.

NovAtel Launches GPS / GLONASS Products at ION Conference

NovAtel OEMStar

NovAtel Inc. rolled out a series of new products and a firmware upgrade at the Institute of Navigation’s ION GNSS 2009 conference held September 22-25 in Savannah, Georgia, USA.

The Calgary, Alberta, Canada–based GNSS manufacturer announced the launch of their new single-frequency GNSS receiver, OEMStar. The low-cost, 14-channel, L1 receiver measures 46 x 71 millimeters and consumes just 750 milliwatts of power when tracking both GPS and GLONASS signals.

Anritsu Selects IFEN GNSS RF Simulator for A-GPS Testing

Anritsu Corporation, a Japanese manufacturer of test and measurement equipment, has selected IFEN’s NavX-NCS Standard GNSS simulator as its assisted-GPS (A-GPS) test system for use in developing mobile terminals.

The NavX-NCS is a GNSS RF navigation constellation simulator capable of simulataneously simulating signals from up to nine L-band frequencies in the GPS, Galileo, GLONASS (including its new G1 frequency), and QZSS systems.

EC to Declare EGNOS Operational for Non-Safety-of-Life Use

The European Commission (EC) expects to declare in October that the European Geostationary Navigation Overlay Service (EGNOS) — which provides satellite-based augmentation signals for GPS and Galileo — is operationally ready as an open and free service for non-safety-of-life (non-SoL) applications, according to a press release from the GNSS Supervisory Authority (GSA).

NOAA, Japan Establish QZSS Ground Station in Guam

Officials from the National Oceanic and Atmospheric Administration and the Japan Aerospace Exploration Agency (JAXA) have unveiled a new ground station in Guam that will track spacecraft from JAXA’s upcoming Quasi-Zenith Satellite System (QZSS).

Designed to work seamlessly with the U.S. Global Positioning System, QZSS is a space-based augmentation system (SBAS) being developed by JAXA to improve navigation satellite coverage over Japan and surrounding areas. The first QZSS satellite is expected to launch in 2010.

With a nearly restored and modernizing GLONASS system beginning to make inroads into mass market products and services, Russia has revealed plans to build out a space-based augmentation system (SBAS) and establish its first ground monitoring stations outside the Russian territory. 

In a July 30 presentation at an International Committee on GNSS (ICG) working group on interoperability, Dmitry Marareskul, head of the onboard satellite navigation sector of Information Satellite System Reshetnev Corporation in Zheleznogorsk, revealed Russia’s plans to expand its network of GLONASS monitoring and measuring stations to include sites in Australia, Cuba, and South America.

U.S. Congress Working on 2010 Appropriations for Loran-C and eLoran as GPS Backup

U.S. Congress Working on 2010 Appropriations for Loran-C and eLoran as GPS Backup

Enhanced Loran (eLoran) has survived through multiple generations of official ambivalence about the proposed backup for the U.S. Global Positioning System. Currently, the program is in (almost) on-again status.

The latest chapter began with President Obama’s Fiscal Year 2010 (FY10) budget proposal, which called for termination of Loran in the coming year. At a May 7 press conference, the president described Loran as a system that’s been eclipsed by the rise of GPS.
