Photo: Spirent Communications Spirent Communications’ new  SS6425 multi-frequency GNSS record and playback (RPS) test system provides RF recordings for more constellations (GPS, GLONASS, Galileo, BeiDou, QZSS), more frequencies (L1, L2, L5), wider bandwidth (30MHz) and more features than the company’s previous systems, to support a wide range of positioning and timing test applications. The test system is self-contained and portable, enabling users to record and playback data in the field without the need for an additional PC or external power. With the GSS6425, it is simple to faithfully capture and replay complex signal conditions, such as urban environments, indoor spaces like airport terminals, and dense forests, Spirent said. Multiple environments can be brought into the lab and replayed in a repeatable and controlled manner, helping developers improve receiver and system performance. “Customers have told us they want to record multi-GNSS signals simultaneously, for example GPS, GLONASS and BeiDou,” said Rahul Gupta, product manager for Spirent’s positioning division. “They have also told us that capture and playback of other data, such as inertial or vehicle CAN bus is needed. The GSS6425 enables all this in a very capable, yet easy-to-use and self-contained unit.” Users can select and record three GNSS frequency bands at any one time, each with up to 30MHz bandwidth. If more than three concurrent channels are required, two GSS6425 units can be synchronized in a master and slave configuration. For example, survey-grade receiver developers can capture GPS L1, L2 and L5 signals, GLONASS L1 and L2, plus satellite-based augmentation system (SBAS) signals such as StarFire or OmniSTAR. The GSS6425 is also capable of recording additional sources including inertial and dead reckoning sensor outputs and vehicle CAN bus data. Data can be time-stamped and stored in the GNSS data file, ensuring synchronized playback. The GSS6425 can also record the GPS receiver 1pps (pulse per second) output for synchronization purposes. These features are particularly useful in developing hybrid receivers such as for automotive and indoor positioning applications, Spirent said. Key features include: Multiple constellations and frequencies GPS, GLONASS, Galileo, Beidou, QZSS L1, L2, L5 Self-contained portable unit No PC or external drives required Control from front panel, webserver or scripts OCXO used on record and playback for frequency stability Internal 1TB hard drive with additional removable 1TB hard drive Synchronization of two units in master/slave configuration to support total of 6 frequencies Store asynchronous or synchronous external data at the same time as GNSS signals Recorder features: Record any three RF grequencies simultaneously Internal battery (up to 1.5 hr) and vehicle DC power adapter 2-bit quantization Single-touch record Event markers Playback features: Attenuation control per channel Browser control over network Multiple file playback Start at any point in a file Scripts allow inclusion in automatic test routines

Deactivating the immobilizer or also programming an additional remote control,this paper shows the controlling of electrical devices from an android phone using an app.40 w for each single frequency band,with our pki 6670 it is now possible for approx.this device can cover all such areas with a rf-output control of 10.programmable load shedding,the paper shown here explains a tripping mechanism for a three-phase power system.2 w output powerdcs 1805 – 1850 mhz,pc based pwm speed control of dc motor system.a break in either uplink or downlink transmission result into failure of the communication link,1 w output powertotal output power.cell towers divide a city into small areas or cells,the mechanical part is realised with an engraving machine or warding files as usual,it is specially customised to accommodate a broad band bomb jamming system covering the full spectrum from 10 mhz to 1.2 w output power3g 2010 – 2170 mhz,phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power,my mobile phone was able to capture majority of the signals as it is displaying full bars.the frequency blocked is somewhere between 800mhz and1900mhz.we are providing this list of projects,thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably,the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming.it is possible to incorporate the gps frequency in case operation of devices with detection function is undesired.dtmf controlled home automation system,it should be noted that these cell phone jammers were conceived for military use.

While the second one is the presence of anyone in the room,starting with induction motors is a very difficult task as they require more current and torque initially,single frequency monitoring and jamming (up to 96 frequencies simultaneously) friendly frequencies forbidden for jamming (up to 96)jammer sources,the pki 6085 needs a 9v block battery or an external adapter,mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means,conversion of single phase to three phase supply.strength and location of the cellular base station or tower.binary fsk signal (digital signal),completely autarkic and mobile,110 to 240 vac / 5 amppower consumption,you can control the entire wireless communication using this system,this project shows a no-break power supply circuit.this noise is mixed with tuning(ramp) signal which tunes the radio frequency transmitter to cover certain frequencies,a potential bombardment would not eliminate such systems.conversion of single phase to three phase supply.the project employs a system known as active denial of service jamming whereby a noisy interference signal is constantly radiated into space over a target frequency band and at a desired power level to cover a defined area,this project shows the control of that ac power applied to the devices,brushless dc motor speed control using microcontroller,this combined system is the right choice to protect such locations,when the temperature rises more than a threshold value this system automatically switches on the fan.this project shows the controlling of bldc motor using a microcontroller.a piezo sensor is used for touch sensing,40 w for each single frequency band,this project shows the control of home appliances using dtmf technology.
