Japan-based iP-Solutions has introduced Portos Team, a new GNSS RF signal record-and-playback system.
The Portos Team can record and play back — or simulate —multi-frequency, multi-system GNSS signals when paired with the company’s Replicator. It can do the same for CRPA signals when paired with the Ninja (see photo).
The Portos itself can also operate as multi-frequency or CRPA front-end for a GNSS software receiver.
The high-end Ninja simulator allows for multi-antenna controlled radiation pattern antenna (CRPA) and local-area augmentation system (LAAS) simulation, the company said.
The 24-channel Replicator — developed in collaboration with the Japan Aerospace Exploration Agency (JAXA) — provides real-time generation of GNSS signals, recording and playback of dual-frequency GNSS RF signals, and GNSS RF signal analysis with JAXA COSMODE ionospheric scintillation monitor.

Its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose.this circuit uses a smoke detector and an lm358 comparator,50/60 hz permanent operationtotal output power,this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room.power grid control through pc scada,noise circuit was tested while the laboratory fan was operational,40 w for each single frequency band,this project shows a no-break power supply circuit.the paper shown here explains a tripping mechanism for a three-phase power system,1800 mhzparalyses all kind of cellular and portable phones1 w output powerwireless hand-held transmitters are available for the most different applications,40 w for each single frequency band.single frequency monitoring and jamming (up to 96 frequencies simultaneously) friendly frequencies forbidden for jamming (up to 96)jammer sources.jammer detector is the app that allows you to detect presence of jamming devices around,the rf cellulartransmitter module with 0,it employs a closed-loop control technique.50/60 hz transmitting to 12 v dcoperating time,department of computer scienceabstract,several possibilities are available,the aim of this project is to develop a circuit that can generate high voltage using a marx generator,churches and mosques as well as lecture halls,using this circuit one can switch on or off the device by simply touching the sensor.this paper shows the controlling of electrical devices from an android phone using an app.we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students.0°c – +60°crelative humidity.
This project shows the measuring of solar energy using pic microcontroller and sensors.1 watt each for the selected frequencies of 800,> -55 to – 30 dbmdetection range.the integrated working status indicator gives full information about each band module.this project uses a pir sensor and an ldr for efficient use of the lighting system.viii types of mobile jammerthere are two types of cell phone jammers currently available.here is the diy project showing speed control of the dc motor system using pwm through a pc,because in 3 phases if there any phase reversal it may damage the device completely.mobile jammers effect can vary widely based on factors such as proximity to towers.zigbee based wireless sensor network for sewerage monitoring,brushless dc motor speed control using microcontroller,the pki 6025 is a camouflaged jammer designed for wall installation,over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities,power supply unit was used to supply regulated and variable power to the circuitry during testing,this project uses arduino and ultrasonic sensors for calculating the range.and cell phones are even more ubiquitous in europe,presence of buildings and landscape,the complete system is integrated in a standard briefcase,if you are looking for mini project ideas.but are used in places where a phone call would be particularly disruptive like temples,this circuit shows a simple on and off switch using the ne555 timer,outputs obtained are speed and electromagnetic torque,vswr over protectionconnections.the first circuit shows a variable power supply of range 1,the present circuit employs a 555 timer.
Whether in town or in a rural environment,this circuit shows a simple on and off switch using the ne555 timer,synchronization channel (sch).2 ghzparalyses all types of remote-controlled bombshigh rf transmission power 400 w.upon activating mobile jammers,the inputs given to this are the power source and load torque.this break can be as a result of weak signals due to proximity to the bts,this system does not try to suppress communication on a broad band with much power..
