EC furthers GMES operations

The European Commission (EC) signed an agreement with European Space Agency (ESA) to provide EUR 104 million fund for the initial operations of the Global Monitoring for Environment and Security programme (GMES). GMES will provide decision-makers with access to accurate and timely information services to manage the environment, understand and mitigate the effects of climate change, and ensure civil security. Since the success of GMES hinges largely on the provision of robust satellite data, ESA is tasked with coordinating the programme’s space component.

US $18bn subsidies to GPS industry

The commercial GPS industry has received an estimated USD 18 billion in implicit subsidies from the US government and is essentially using the GPS satellite network at no cost. In contrast, commercial wireless broadband providers must invest billions of dollars in building and maintaining a network of transmission sites and satellites and ensuring that there is no interference with GPS receivers. By using the GPS satellite network free of charge, commercial GPS device manufacturers enjoy substantial benefits at no cost. However, in order to offer the same geo-location services, these commercial users would have to rely on some equivalent system. This is a cost that the commercial GPS users do not face, because the federal government allocates valuable spectrum for GPS transmissions and invests in GPS satellite infrastructure and operations.

Gagan in final operational phase

The initial phase of GPS-Aided Geo Augmented Navigation (GAGAN) system is now over. The project is currently in the final operational phase. It is now going through the certification stage of the Satellite-Based Augmentation System (SBAS) which will be completed by June 2013. After its final operational phase completion, the estimated cost of GAGAN would be over INR 780 crore. GAGAN’s certification process is also being carried out with Directorate General of Civil Aviation and other bodies, with the AAI and the Indian Space Research Organisation (ISRO) developing it.

Panchayat using GPS-based
attendance system in India

Patan District Panchayat in Gujarat, India, has come up with ‘Present please project’. Under this project, every employee will be given one number. When employees reach the place of their work, they will have to SMS the District Panchayat. This will be an SMS based attendance verification system powered by GPS, so it can show the location of the officer. If the person is late or has not messaged then it will be considered absence.

Six GLONASS satellites in 2011

Russian Space Agency Roscosmos will launch five Glonass-M satellites and one Glonass-K satellite in 2011. The first launch of the Glonass-M satellite is scheduled for August and the second is slated for October. The Glonass-K is expected to be launched in December.

South Korea to curb illegal GPS jammer

The Korea Communications Commission in Seoul will conduct a crackdown to curb the production and sale of GPS jamming devices, which are illegally sold in the market. They will develop low-cost equipment that can quickly detect where GPS jamming GPS data can detect buried nuke tests A computer program that uses data from GPS satellite receivers placed in nearby countries pinpoints the explosion, uncovering the clandestine act. When a nuclear weapon is detonated – even thousands of feet underground – a shockwave radiates in the atmosphere. This changes electron density in the field of charged particles in the part of the upper atmosphere known as the ionosphere. Jihye Park, 30, a South Korea native and doctoral student in geodetic science at Ohio State, created the computer program using GPS data to detect this change in the ionosphere.

First Quasi-Zenith Satellite
‘MICHIBIKI’ begins

The Japan Aerospace Exploration Agency (JAXA) confirmed that the quality and reliability for positioning signals (L1- C/A and L2C*1) of the First Quasi-Zenith Satellite (QZS) “MICHIBIKI” satisfied the QZSS system user interface specifications (IS-QZSS) through technological verification, thus lifting the alert flag*2 for the L1-C/A and L2C positioning signals on June 22.

Japan GPS satellites cut from 7 to 4

The Japanese version of the GPS likely will operate with four satellites not the initially planned seven to save money, although this will not reduce the system’s accuracy. By supplementing and reinforcing the U.S. GPS, the Japanese version will be 10 times more accurate than current positioning information. Having four satellites will ensure signals can better reach locations in mountainous regions and areas surrounded by high-rise buildings. Michibiki can be used only for eight hours a day–the time it is in orbit above Japan.

Eyeing for Philippine aerospace

The Civil Aviation Authority of the Philippines (CAAP) will develop a performance-based navigation (PBN) system in cooperation with the French Civil Aviation Authority and Quovadis, an Airbus company specializing in flight operations systems. The Required Navigation Performance allows an aircraft to fly accurately defined and contained trajectories without relying on ground-based navigation aids. The navigation technology allows for optimal use of airspace by making approaches more stabilized and managed.
