ARIANESPACE’S FIRST ARIANE 5 LAUNCH FOR GALILEO CONSTELLATION AND EUROPE

09. November 2016, Veronika Sax - Galileo

 

For its ninth launch of the year, and the sixth Ariane 5 liftoff from the Guiana Space Center (CSG) in French Guiana during 2016, Arianespace will orbit four more satellites for the Galileo constellation. This mission is being performed on behalf of the European Commission under a contract with the European Space Agency (ESA).

For the first time, an Ariane 5 ES version will be used to orbit satellites in Europe's own satellite navigation system. At the completion of this mission, designated Flight VA233 in Arianespace's launcher family numbering system, 18 Galileo spacecraft will have been launched by Arianespace.

 Arianespace is proud to deploy its entire family of launch vehicles to address Europe's needs and guarantee its independent access to space.

The launch will be performed from Ariane Launch Complex No. 3 (ELA 3) in Kourou, French Guiana. The Launch Readiness Review (LRR) will take place on Monday, November 14, 2016 in Kourou, to authorize the start of operations for the final countdown.

Galileo, an emblematic European program

The new Galileo global satellite navigation system is an emblematic European Union program - led by its Directorate General for Internal Market, Industry, Entrepreneurship and SMEs (GROWTH); with ESA assigned the responsibility for design and procurement.

The Galileo FOC (Full Operational Capacity) satellites are built in Europe by OHB System of Bremen, Germany as prime contractor, with all payloads supplied by SSTL (Surrey Satellite Technology Ltd.), a British subsidiary of Airbus Defence and Space.

For further information, download the launch kit here.

To watch a live, high-speed online transmission of the launch (including commentary from the launch site in French and English), go to arianespace.com on November 17, 2016, starting 20 minutes before liftoff.

IFEN GMBH ATTENDING INTERGEO 2016 WITH PARADISE

13. October 2016, Veronika Sax - IFEN Company, Events, Shows & Trade Fairs

 

INTERGEO, which consists of a conference and a trade fair, is the world's largest event for geodesy, geoinformation and land management. It is held every year at different venues in Germany. The conference deals with current issues from politics, administration, science and industry, and had around 1,300 participants. At this year's leading trade fair, more than 17,000 visitors discovered the latest innovations from 531 companies from 37 different countries.

IFEN GmbH attended these years INTERGEO in Hamburg from 11- 13 October as part of the common booth of ESA BIC/Sat Nav-Forum/GSA to represent the PARADISE project.

The primary objective of the PARADISE project is to develop innovative signal processing and navigationalgorithms bringing precise GNSS positioning and IMU attitude available to applications where to date GNSS could not be adopted due to prohibitively bad signal conditions, such as urban canyon and forest environment. These new PARADISE algorithms will be validated using a newly developed 'Proof-of-Concept' breadboard. Furthermore several user applications will be demonstrated with a prototype receiver within the scope of the project.

This project has received funding from the European GNSS Agency under the European Union's Horizon 2020 research and innovation programme under grant agreement no. 641629.

The project partners in PARADISE are:

 

  • IFEN GmbH (coordinator)
  • GRINTEC Gesellschaft für graphische Informations-Technologie mbH
  • Vermessung Dr. Günther Abwerzger
  • Czech Technical University in Prague, Faculty of Civil Engineering, Department of Geomatics
  • HSM Hohenloher Spezial-Maschinenbau GmbH & Co. KG

PRESS RELEASE: IFEN’S NEW NCS TITAN GNSS SIMULATOR - THE MOST POWERFUL AND FLEXIBLE GNSS SIMULATOR, IN A COST EFFECTIVE PACKAGE

13. September 2016, Veronika Sax - IFEN Products

 

Poing, Germany - IFEN GmbH, the leading manufacturer of GNSS navigation test and development products and services, today announced the launch of its new NCS TITAN GNSS Simulator.

The unique flexibility and outstanding performance of the NCS TITAN GNSS Simulator is beyond the capabilities of any other simulator currently on the market. With up to 256 channels (and 1024 multipath channels) and up to 4 RF outputs per chassis, the extra complexity and cost of using multiple signal generators is avoided, improving reliability without compromising on functionality.

The innovative design of the NCS TITAN allows users configure channels for any GNSS signals and allocate those channels to any of the RF outputs fitted. This flexibility enables the same Simulator hardware to be used for an extensive range of tests, for all types of GNSS applications. The NCS TITAN sets new standards in the field of GNSS Simulation, in terms of fidelity, accuracy, dynamics, iteration rates and reliability.

"The launch of our brand new NCS TITAN GNSS Simulator represents another milestone for our NCS GNSS simulator products", explains Dr. Günter Heinrichs, Head of Customer Applications. "This shows clearly once again our commitment to ongoing product enhancement and dedication to providing our customers with best GNSS test equipment on the Market". The NCS TITAN GNSS Simulator has been developed in cooperation with WORK Microwave GmbH, Germany.


SLAB HELPS PUSH GLIDERS TO THE EDGE OF SPACE - STANFORD`S SPACE RENDEZVOUS LAB USING IFEN NAVX-NCS PROFESSIONAL GNSS SIMULATOR

08. July 2016, Veronika Sax - IFEN Products

For over 17 years the scientists, engineers, and pilots of the Perlan Project have pushed the edge of manned glider flight, using South American mountain winds to surf the air to ever higher altitudes. This July they will attempt to set the world record for high altitude unpowered flight, soaring to the edge of space at 90,000 feet-almost double the previous record of 50,721 feet. The world of competitive gliding is regulated by the Fédération Aéronautique Internationale (FAI) - The World Air Sports Federation, which oversees all aspects of glider flight record attempts and their certification. Specifically, the FAI's Global Navigation Satellite System (GNSS) Flight Recorder Approval Committee determines which GNSS-based flight recorders can be used for high-altitude record attempts. Currently, the LX-9000 is the only approved flight recorder for high-altitude glider record attempts, but it has never been tested above 40,000 ft, that is until SLAB's PhD student Duncan Eddy and GPS Lab's Researcher Todd Walter started helping under the supervision of Prof. Simone D'Amico.

Eddy and Walter used SLAB's high-fidelity IFEN GNSS signal simulator to test Perlan's dual LX-9000 flight recorders with simulated Global Positioning System (GPS) signals similar to those the receivers will see on the day of their world-record-attempt flight late this July. Since the only known winds that can propel a glider to the stratosphere occur in the remote mountains of southern Argentina, the GNSS signal simulator represents the only way to verify the functionality and performance of the flight recorders at that location, before the actual flight. The testing set-up (pictured left) and the rigorous scenario definition, which reproduces the planned climbing trajectory, helped uncover information regarding the behavior of the flight recorders that is crucial for the successful validation of any record setting attempt. This was only possible thanks to the experience gained by Duncan Eddy with the IFEN GNSS signal simulator in the frame of his PhD on advanced algorithms and hardware for precision GNSS navigation in space.
