21. September 2015, admin - IFEN Company, Events, Shows & Trade Fairs


From 15th till 18th September 2015 IFEN had the chance to be part of this year's ION GNSS Show in Tampa.

Great located with booth 400 close to the centre of the exhibition hall, Dr. Günter Heinrichs (IFEN GmbH) and Mark Wilson (IFEN Inc.) have been meeting several customers and potential prospects to discuss future opportunities as well as current experiences with our GPS/GNSS test equipment.

Interested visitors had the chance to try out our NavX-NCS Professional GNSS Simulator as well as our SX3 GNSS Software Receiver at our new media counters and get a first impression on performance, capability and flexibility of our NavX-NCS and SX3 products.

We are looking forward to the ION GNSS Show 2016 in Portland, Oregon.


19. August 2015, admin - GATE


As part of a week-long training in the Training Institute of the Bavarian Police in Ainring, officials of the Special Forces Operations Command from the Police South Bavaria visited the Galileo Test and Development Environment (GATE) in Berchtesgaden.

One of the main tasks of the unit is the covert data collection, including the use of technical means. In order to determine, control and surveillance of site locations, such as in containers with dangerous goods, among with others the Global Navigation Satellite System GPS is used. According to visitor statement it is politically scheduled, depending on the successful deployment of the Galileo navigation system, to use the Galileo system in case of application in future. Against this background, information about Galileo, as well as a visit to the world's unique Galileo terrestrial open air testing environment 'GATE' was meaningful and purposeful for the experts.

GATE service engineer of the operating company IFEN GmbH Mr. Kern explained at the beginning of his speech the general principles and functions of satellite-based positioning and explained and presented in a second step the differences from the test environment GATE in a comprehensible way. The lecture was concluded with some user examples for a better illustration. In the end it was possible to show the visitors all eight GATE transmitting stations on the mountains around Berchtesgaden.

The participants thanked for a very informative and insightful talk which included some interesting information, despite their daily tech-savvy work so not known.

Processor Technology for GNSS Software receiver in the year 2015

Recent increases in computational power can be used to build more efficient GNSS software receivers.  Experimental benchmarks show how well the currently available technology can be exploited for these purposes. A personal computer (maximum number channels greater than 1,000) and an embedded board (maximum number of channels less than 100) are tested under various scenarios, with promising results for future applications.

For several times in the past seven months, the Universität der Bundeswehr München came to Berchtesgaden, to utilize the Galileo Test and Development Environment GATE.

This time tests of ITS (Intelligent Transport Systems) systems stood in the foreground. They are used for communication between different road users. In this way, vehicle data can be exchanged, which is essential for driver assistance systems or automated driving.

For the application, it is very important to check the reliability of the user position determined by satellite navigation systems. To this end, radar signals were initially emitted of a moving car and "sampled" the roadsides. Trees or houses are recognized such as moving objects, e. g. pedestrians, cyclists and other vehicles. If for example a pedestrian crosses the street, the radar system detects the situation in time. Current driver assistance systems have the option of initiate braking or evasive maneuvers automatically. At the same time the information of the brake or taken evasive action is transmitted to vehicles in the vicinity, so that they are warned. Also cyclists can be detected by radar. With ITS it is possible to send a warning to vehicles behind.

One test scenario conducted in GATE, was the one vehicle driving after another vehicle at a constant distance. The guiding vehicle recorded the pure satellite position and the following vehicle additionally checked the determined position with radar signals. The Fraunhofer Institute for Embedded Systems and Communication Technology (ESK) from Munich supported the Test series with their test vehicle. To control the GATE signals through the whole trial period the measurement vehicle of GATE was located at GATE central point.

The test responsible person in charge of Universität der Bundeswehr München recorded on the second day for about 2 hours Galileo signals in addition to GPS and GLONASS signals in the GATE office. To test the newly developed ARAIM (Advanced Receiver Autonomous Integrity Monitoring) algorithms for detection of faulty satellite data, the position of a GATE "satellite" was temporarily deflected artificially. Afterwards the same series of tests has been dynamically recorded over one hour, driving through the GATE test bed of Berchtesgaden, in the IFEN measurement vehicle.

According to first statements both test days have been very successful.
