GPS – Global Positioning System

Mass GPS Spoofing Attack in Black Sea?

GPS Spoofing Attack in Black SeaReports of satellite navigation problems in the Black Sea suggest that Russia may be testing a new system for spoofing GPS. This could be the first hint of a new form of electronic warfare available to everyone from rogue nation states to petty criminals.

On 22 June, the US Maritime Administration filed a seemingly bland incident report. The master of a ship off the Russian port of Novorossiysk had discovered his GPS put him in the wrong spot – more than 32 kilometres inland, at Gelendzhik Airport. Read more…

First GPS signal received 40 years ago

Working well after midnight on July 19, 1977, a Rockwell Collins engineer named David Van Dusseldorp sat on the rooftop of a company building in Cedar Rapids, Iowa, adjusting an antenna every five minutes to receive a signal from the world’s first Global Positioning System (GPS) satellite, known as NTS-2.

Within a small window of time, the satellite was turned on and the message was successfully received and decoded by the team working the GPS receiver below.

Since then, the technology has grown to be the standard of navigation around the world and touches nearly every part of our daily lives. To commemorate the 40-year anniversary, Rockwell Collins invited retirees involved in the project to share their firsthand stories at an event held in Cedar Rapids today. Read more…

Father of GPS meets Europe’s Galileo team

Brad ParkinsonBrad Parkinson, hailed as the father of GPS, has visited ESA’s technical heart to meet the team behind Europe’s Galileo satellite navigation system.

Brad Parkinson was awarded the 2016 Marconi Prize for his part in developing satellite navigation. In 1972, then a US Air Force Colonel, he was put in charge of “Program 621B”, which became the Global Positioning System. Over one long September weekend in 1973 he and his team decided all key GPS elements. The first satellite was launched in February 1978.

Paul Verhoef, ESA’s Director of the Galileo Programme and Navigation-related Activities, invited Prof. Parkinson to ESA’s facility in the Netherlands to address the Directorate’s annual gathering on 11 January. Also present were members of the European Global Navigation Satellite System Agency – set to oversee newly operational Galileo services – and the European Commission. Read more…

NASA and ESA to Test GPS and Galileo Receivers on Board the International Space Station

The National Aeronautics and Space Administration (NASA), the European Space Agency (ESA) and Qascom, an Italian company specializing in Galileo, are collaborating to build the first GPS and Galileo receiver to be tested on board the International Space Station (ISS) Space Communications and Navigation (SCaN) Testbed.

SCaN is a payload developed by NASA that has been hosted on board the International Space Station on an external truss since late 2012. It has the objective of testing navigation and communication experimentations with a Software Defined Radio (SDR) approach, which permits software only updates for testing new experimental configurations.

GPS and Galileo: a winning combination for aviation and beyond

Twenty years ago, the air transport sector clearly identified the benefits of GPS for flight management and air traffic control. Today, the future of Global Navigation Satellite Systems (GNSS) lies in a combined use of GPS and Galileo.Topstar-200

This year, the first LPV-200 approach was successfully made at Paris Charles de Gaulle airport (http://galileognss.eu/first-egnos-lpv-200-approach/), the first such approaches to be implemented in Europe. It was achieved using GPS SBAS/LPV (EGNOS) receivers, lending further credibility to the EGNOS GNSS system. Read more…

GPS IIF-8 launch successful

United Launch Alliance’s (ULA) Atlas V two-stage rocket liftoff from Cape Canaveral last 29-October with GPS IIF-8 aboard.

Built by Boeing, GPS IIF-8 is one of the next-generation GPS satellites, incorporating various improvements to provide greater accuracy, increased signals, and enhanced performance for users. It is the eighth GPS IIF satellite launched, the fourth this year by ULA. Three are in storage awaiting launch, and one is in production for a total of twelve of this series replacing GPS IIA.
