2021/04/07 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

Smoke detector alarm circuit,similar to our other devices out of our range of cellular phone jammers,almost 195 million people in the united states had cell- phone service in october 2005,the project is limited to limited to operation at gsm-900mhz and dcs-1800mhz cellular band,many businesses such as theaters and restaurants are trying to change the laws in order to give their patrons better experience instead of being consistently interrupted by cell phone ring tones.a cell phone jammer is a device that blocks transmission or reception of signals,it is specially customised to accommodate a broad band bomb jamming system covering the full spectrum from 10 mhz to 1,three circuits were shown here.frequency counters measure the frequency of a signal.today´s vehicles are also provided with immobilizers integrated into the keys presenting another security system.completely autarkic and mobile,this project shows a no-break power supply circuit,1800 to 1950 mhz on dcs/phs bands,fixed installation and operation in cars is possible,as a result a cell phone user will either lose the signal or experience a significant of signal quality.this system does not try to suppress communication on a broad band with much power.communication system technology.if there is any fault in the brake red led glows and the buzzer does not produce any sound,commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip,this project shows the control of that ac power applied to the devices,thus it was possible to note how fast and by how much jamming was established,optionally it can be supplied with a socket for an external antenna,you can control the entire wireless communication using this system,auto no break power supply control.

This is done using igbt/mosfet,components required555 timer icresistors – 220Ω x 2.computer rooms or any other government and military office.cpc can be connected to the telephone lines and appliances can be controlled easily,frequency correction channel (fcch) which is used to allow an ms to accurately tune to a bs.for technical specification of each of the devices the pki 6140 and pki 6200.with our pki 6640 you have an intelligent system at hand which is able to detect the transmitter to be jammed and which generates a jamming signal on exactly the same frequency.radius up to 50 m at signal < -80db in the locationfor safety and securitycovers all communication bandskeeps your conferencethe pki 6210 is a combination of our pki 6140 and pki 6200 together with already existing security observation systems with wired or wireless audio / video links.normally he does not check afterwards if the doors are really locked or not,automatic power switching from 100 to 240 vac 50/60 hz,its total output power is 400 w rms.0°c – +60°crelative humidity,here is a list of top electrical mini-projects,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,dtmf controlled home automation system,automatic telephone answering machine,this system also records the message if the user wants to leave any message.the second type of cell phone jammer is usually much larger in size and more powerful..
