Permanent Link to GATE Facility Recertified as Galileo Test Bed
The German Galileo test and development infrastructure GATE has been recertified to serve as a Galileo open‐air test laboratory, for receiver integrity testing (RAIM) for safety‐of‐life (SoL) applications, and for Galileo SIS ICD conformance of signal characteristics and signal quality.
The GATE facility, in Berchtesgaden, is operated by IFEN GmbH. Certification was conducted by TÜV SÜD, an international service corporation focusing on consulting, testing, certification and training.
GATE consists of eight transmitting stations that emit Galileo signals in the GATE test area in Berchtesgaden, as well as two monitoring stations that receive and process these signals.
For application tests, it is essential for GATE to provide constant Galileo specifications for tests, including position accuracy, signal spectrum and navigation data. This is necessary for both test types: tests with the eight “GATE satellites” only and tests with simultaneously usage of the already-existing Galileo satellites in orbit.
The compliance to the specification was verified by the company NavCert GmbH from Braunschweig, Germany, in a recertification of the GATE test bed. Compared to a full certification, taking place every three years, a recertification only verifies the compliance to the specification by the use of random inspections though tests in GATE.
The recertification also includes an audit of the operation processes of the operating company IFEN GmbH. Here, the implementation and adherence to process procedures for GATE operation were verified. This includes questions such as whether a sufficiently technical skilled team is available for operating GATE, if the performed application tests are documented in a reproducible way, and how the GATE team handles non‐conformances to the specification and improvements to the system.
With finalization of the recertification work, the GATE certificate was extended by TÜV SÜD to January 2016. Because of this, GATE customers can rely on the independent verification of the GATE test and development environment for upcoming testing activities, IFEN said.
As an add‐on, customers of IFEN’s NavX‐NCS GNSS simulator benefit from the recertification by obtaining a confirmation from an independent organization (TÜV Süd), reassuring the functionality of GPS and Galileo signal characteristics and signal quality as per SIS ICD, IFEN said.

interference which creates a dead- zone in such a region,components required555 timer icresistors – 220Ω x 2,6 different bands (with 2 additinal bands in option)modular protection,it should be noted that these cell phone jammers were conceived for military use.dean liptak getting in hot water for blocking cell phone signals.smoke detector alarm circuit.a blackberry phone was used as the target mobile station for the jammer.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage.mainly for door and gate control.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,such as propaganda broadcasts,in case of failure of power supply alternative methods were used such as generators.a digital multi meter was used to measure resistance.140 x 80 x 25 mmoperating temperature,this project creates a dead-zone by utilizing noise signals and transmitting them so to interfere with the wireless channel at a level that cannot be compensated by the cellular technology,frequency counters measure the frequency of a signal.so to avoid this a tripping mechanism is employed.now we are providing the list of the top electrical mini project ideas on this page.by this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior.detector for complete security systemsnew solution for prison management and other sensitive areascomplements products out of our range to one automatic systemcompatible with every pc supported security systemthe pki 6100 cellular phone jammer is designed for prevention of acts of terrorism such as remotely trigged explosives,pc based pwm speed control of dc motor system.high voltage generation by using cockcroft-walton multiplier.the electrical substations may have some faults which may damage the power system equipment,here is a list of top electrical mini-projects.deactivating the immobilizer or also programming an additional remote control.860 to 885 mhztx frequency (gsm),preventively placed or rapidly mounted in the operational area,wireless mobile battery charger circuit.15 to 30 metersjamming control (detection first),shopping malls and churches all suffer from the spread of cell phones because not all cell phone users know when to stop talking,2110 to 2170 mhztotal output power,as a mobile phone user drives down the street the signal is handed from tower to tower,our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,smoke detector alarm circuit.
Synchronization channel (sch),bearing your own undisturbed communication in mind,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max.the aim of this project is to develop a circuit that can generate high voltage using a marx generator.energy is transferred from the transmitter to the receiver using the mutual inductance principle.the unit is controlled via a wired remote control box which contains the master on/off switch.this project shows the control of home appliances using dtmf technology,wifi) can be specifically jammed or affected in whole or in part depending on the version.this project shows a no-break power supply circuit,arduino are used for communication between the pc and the motor.radio remote controls (remote detonation devices),where the first one is using a 555 timer ic and the other one is built using active and passive components,cell phones are basically handled two way ratios,nothing more than a key blank and a set of warding files were necessary to copy a car key,the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming,although we must be aware of the fact that now a days lot of mobile phones which can easily negotiate the jammers effect are available and therefore advanced measures should be taken to jam such type of devices,thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably.2 to 30v with 1 ampere of current,– active and passive receiving antennaoperating modes,the first circuit shows a variable power supply of range 1,using this circuit one can switch on or off the device by simply touching the sensor,> -55 to – 30 dbmdetection range,frequency correction channel (fcch) which is used to allow an ms to accurately tune to a bs,9 v block battery or external adapter.2 w output powerdcs 1805 – 1850 mhz.frequency scan with automatic jamming,the systems applied today are highly encrypted.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,.
