RACELOGIC SKYDEL SPIRENT FEDERAL SYSTEMS SYNTONY GNSS TALEN-X OROLIA/SPECTRACOM CAST NAVIGATION CAST-5000 GPS wavefront generator The CAST-5000 produces a single coherent wavefront of GPS RF signals to provide repeatable testing in the laboratory environment or anechoic chamber. The basic system generates four independent, coherent simulations that reference a single point and is upgradeable to support seven elements for CRPA testing. With an intercard carrier- phase error of less than 1 millimeter, the CAST-5000 is extremely accurate. The system generates a wavefront of GPS when its GPS RF generator cards are operated in a ganged configuration. Each generator card provides a set of GPS satellites coherent with the overall configuration. Several RF generator cards may be utilized together, ensuring phase coherence among the bank of signal generator cards. The CAST-5000 Controlled Reception Pattern Antenna (CRPA) tester allows a full end-to-end test of the antenna system. The CRPA antenna, antenna electronics and the GPS receiver can be tested as a unit with or without radiating signals.

CLAW 18-channel real-time GPS simulator for manufacturing testing, laboratory and desktop simulation applications The CLAW simulator operates as a fully stand-alone simulator with multipath simulation capability, external real-time NMEA to GPS-RF transcoding capability, sub 5-ns UTC time-encoding accuracy. It can work either from internally stored motion files, a fixed-position, externally applied NMEA stimulus input, or controlled via a Jackson Labs Windows application. The CLAW allows comprehensive scenarios to be set up inACKcluding uploading of custom almanac and ephemerides via RINEX import, and full control of simulation time and date making it easy to simulate GPS events such as leap seconds and week 1023 rollover events. The highly accurate simulator can be used as an embedded module to transcode modern GNSS or inertial navigation system (INS) position, navigation and timing signals including SAASM and M-code into legacy GPS RF signals. This capability allows retrofitting any existing legacy GPS receiver to the latest Assured-PNT capability. It can also be used as a GPS firewall to automatically detect and mitigate spoofing and jamming events. RSR transcoder GPS simulator for retrofitting existing legacy GPS equipment to any GNSS, INS and atomic holdover capability The size of a postage stamp, the RSR Transcoder is based on the Jackson Labs CLAW simulator technology and is designed to be integrated into systems requiring retrofit of existing GPS legacy equipment with INS and atomic clock holdover capability, as well as the latest GNSS capability such as Galileo, GLONASS, BeiDou, SAASM, M-code and CSAC technology. Because the RSR Transcoder is fully self-contained, it also can work as a generic stand-alone GPS simulator for manufacturing environments or laboratory use. It is compatible with various external MIL-STD GPS receivers for glueless integration into existing vehicles by replacing the existing GPS antenna with the RSR Transcoder connected to an external GNSS receiver and optional high-performance INS. The RSR Transcoders ability to convert latest-generation GNSS receiver NMEA information into legacy GPS RF signals can also be used to upgrade low-performance legacy GPS receivers with modern –167 dBm and SBAS tracking capability for indoor reception and increased PNT accuracy in challenged environments.

The Constellator product is available in different ranges, from an entry-level unit supporting L1C/A up to a six-signal-frequencies/200 channels rack, supporting the most demanding configurations. Constellator is used extensively in the aeronautic, space and defense industries, where the requirements are highly demanding. Constellator has been carefully evaluated and selected by major industrial companies and agencies worldwide, and is used to test aircraft receivers, spacecraft, launchers and similar systems for defense and armies. Particularly in the space domain, Constellator implements the most accurate models (earth gravity, drag, etc.) needed to achieve “meter-precision” in standalone mode around a complete orbit. Constellator is based on modern, powerful software-defined radio (SDR) systems, which make it capable of extreme adaptability and upgradeability after purchase, even without any hardware upgrade. Though a high-end simulator, it is cost-effective because of its software-based architecture; instead of requiring one RF stage per signal, it requires just one per frequency band used. The Echo Record and Playback unit allows users to record real-life signals and environments and replay them in the laboratory, which is always more realistic than any simulation. Echo is typically used to replay predefined complex and very long realistic scenarios, avoiding the need to use costly satellite simulators for long-run tests or for production tests. Echo offers three RF channels of 100-Mhz bandwidth each, 16 bits I, 16 bits Q, and more than 10 hours of record and replay duration. As such, it is high-end record/replay equipment, offering high-end replay fidelity. www.syntony-gnss.com Email: François Goudenove, chief sales officer, francois.goudenove@syntony-gnss.com (ask François for the contacts of distributors in the U.S., Europe, India, China, South Korea, Japan.)

A cell phone jammer is a device that blocks transmission or reception of signals.this project shows the control of that ac power applied to the devices.several possibilities are available.a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station,6 different bands (with 2 additinal bands in option)modular protection,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,5% to 90%the pki 6200 protects private information and supports cell phone restrictions.cell phones are basically handled two way ratios.2100 to 2200 mhzoutput power.programmable load shedding,go through the paper for more information,because in 3 phases if there any phase reversal it may damage the device completely,a cell phone works by interacting the service network through a cell tower as base station,jammer disrupting the communication between the phone and the cell phone base station in the tower,these jammers include the intelligent jammers which directly communicate with the gsm provider to block the services to the clients in the restricted areas,the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming,vehicle unit 25 x 25 x 5 cmoperating voltage,you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls.50/60 hz transmitting to 12 v dcoperating time,. 4g lte 4g wimax cell phone jammerhidden cellphone jammer headphonescellphone and wifi jammercell phone jammer Newrycell phone jammer kit planscell phone jammer Lacombecell phone jammer Lacombecell phone jammer Lacombecell phone jammer Lacombecell phone jammer Lacombe cell phone jammer 5g5g cell phone jammers5g cell phone jammers-cell phone and gps jammers wikiraptor cell phone jammercell phone jammer Lacombecell phone jammer Lacombecell phone jammer Lacombecell phone jammer Lacombecell phone jammer Lacombe
