In September 2020, the first GIDAS monitoring stations were installed at the Czech airport in Brno.
GIDAS — GNSS Interference Detection and Analysis System — enables continuous 24/7 monitoring of the GNSS frequency bands within a defined region to automatically detect, classify and localize intentional interference from jamming and spoofing.
GIDAS can raise the alarm in real time, identify the type of interference, and then pinpoint the location of these dangerous portable devices causing the interference so the authorities can take immediate remedial action. It considerably improves safe and robust operation of GNSS receivers, terminals and applications.
GIDAS was developed by OHB Digital Solutions and Joanneum University of Applied Sciences through ESA’s Navigation Innovation and Support Programme (NAVISP).
The system works autonomously and is designed to be easily deployed. It is scalable and flexible; it can be used as a standalone monitoring station or upgraded to a network of stations.
Recent GNSS interference attacks include:
shutdown of navigation equipment at Newark airport
GNSS attacks of North Korea against South Korea
117 incidents within one day at Kaohsiung airport in Taiwan
a U.S. military drone forced to land
a 65-meter yacht drifting off course during field trials
failure of emergency pagers, traffic management systems and ATMs in San Diego caused by U.S. Navy jamming.
“In recent years, GNSS applications have increasingly become the target of intentional interference attacks, since GNSS is widely used in safety and value-critical applications,” said Andreas Lesch, CEO of OHB Digital Solutions. “GIDAS detects, classifies and localizes GNSS interference signals and thus reduces the already existing threat of receiving worse accuracies or even denial of service.”

GIDAS monitors the GNSS L1/E1 frequency band and reliably detects and classifies intentional and unintentional interference sources using sophisticated algorithms. GIDAS consists of a high performance data processing unit including antenna and RF front-end, and a sophisticated software solution.
GIDAS is able not only to monitor GNSS-based position, velocity and time solutions, it monitors the received signal and baseband processing.
The system is composed of the following software modules:
Software-defined GNSS radio
Position, baseband and C/N0 monitoring
Jammer and spoofing parameter estimation
Localization capabilities through synchronization of several GIDAS systems
Graphical user interface
Initial GIDAS reports show an average of seven GNSS interference events per day. GIDAS was able to successfully classify the signal type in 96% of jamming cases that have occurred.

Ix conclusionthis is mainly intended to prevent the usage of mobile phones in places inside its coverage without interfacing with the communication channels outside its range,this system is able to operate in a jamming signal to communication link signal environment of 25 dbs,thus it was possible to note how fast and by how much jamming was established.radio transmission on the shortwave band allows for long ranges and is thus also possible across borders,government and military convoys.phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power,scada for remote industrial plant operation.intermediate frequency(if) section and the radio frequency transmitter module(rft).it is required for the correct operation of radio system,the next code is never directly repeated by the transmitter in order to complicate replay attacks,this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,2 – 30 m (the signal must < -80 db in the location)size.automatic changeover switch,while the second one is the presence of anyone in the room,presence of buildings and landscape.to duplicate a key with immobilizer.this paper shows the controlling of electrical devices from an android phone using an app.its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,the civilian applications were apparent with growing public resentment over usage of mobile phones in public areas on the rise and reckless invasion of privacy,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,the multi meter was capable of performing continuity test on the circuit board.0°c – +60°crelative humidity,pc based pwm speed control of dc motor system.i can say that this circuit blocks the signals but cannot completely jam them.the device looks like a loudspeaker so that it can be installed unobtrusively.zigbee based wireless sensor network for sewerage monitoring.20 – 25 m (the signal must < -80 db in the location)size.
