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.

THE 'UNIVERSITÄT DER BUNDESWEHR' USES GATE, THE GALILEO TEST AND DEVELOPMENT ENVIRONMENT IN BERCHTESGADEN

09. July 2015, Veronika Sax - Galileo

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.
