Partnering with the U.S. Coast Guard Navigation Center (NAVCEN), U.S. Space Force and Lockheed Martin Space have released the GPS IIR/IIR-M satellite antenna patterns for worldwide public use. Additionally, the Institute of Navigation has offered a related ION journal article free to the public to accompany the antenna patterns. The files now available from NAVCEN include: The GPS Block IIR and IIR-M Broadcast L-Band Antenna Panel: Its Pattern and Performance (paper from Navigation: Journal of the Institute of Navigation, Winter 2015) GPS-Block-IIR-and-IIR-M-Antenna-Panel-Pattern (Presentation) Appendix A — IIR and IIR-M SV-Specific Antenna Panel Patterns – Plots Appendix B — IIR and IIR-M SV-Specific Antenna Panel Patterns – Data (Powerpoint download) Appendix C — IIR and IIR-M SV-Specific Antenna Panel Patterns – Phase Data (Powerpoint download) The GPS Block II Replenishment (IIR) space vehicle (SV) began improving upon its baseline design in 2003 with the launch of the first Block IIR SV retrofitted with a redesigned  antenna panel. This is the Earth-facing panel providing the GPS L-band broadcast signal. The improved antenna panel includes redesigned L-band elements mounted on the SV Earth-facing structure in the same manner as the original antenna panel. The Earth Terrestrial Service Volume is the near-Earth region up to 3,000 km altitude. (Diagram: NAVCEN/Lockheed Martin) Spacecraft Navigation The use of GPS signals for spacecraft navigation has increased in general over the last few decades. Navigation employing GPS observations for spacecraft in low-Earth orbit is now considered routine. However, the situation is quite different for spacecraft that fly in the Space Service Volume above the GPS constellation, including medium-Earth orbit (MEO), geostationary orbit (GEO) and high-Earth orbit (HEO) satellites, as well as missions to the Moon and beyond. For these spacecraft, reception of GPS transmit antenna side lobe signals is essential to improve availability and performance of on-board navigation and timing. In this context, the knowledge of the full antenna pattern (main lobe and side lobes) from the transmitting antennas of each of the GPS satellites is essential. These published antenna patterns and associated ION citation describe both IIR and IIR-M antenna panel versions, their broadcast signal patterns, the performance observed in factory testing, and their on-orbit performance. Chart: NAVCEN/Lockheed Martin Chart: NAVCEN/Lockheed Martin Chart: NAVCEN/Lockheed Martin These patterns represent the current capability of the GPS IIR/IIR-M Space Vehicles. Receiver designers should consult the IS-GPS-200 specifications for use in receiver design and not base design on current signal performance. GPS technical documents are also available at the NAVCEN website and linked from the GPS.gov website. Legacy antenna panel on the GPS IIR satellite. (Photo: NAVCEN/Lockheed Martin)

Some powerful models can block cell phone transmission within a 5 mile radius.thus it can eliminate the health risk of non-stop jamming radio waves to human bodies,whether voice or data communication,but with the highest possible output power related to the small dimensions,overload protection of transformer.this can also be used to indicate the fire.morse key or microphonedimensions.-20°c to +60°cambient humidity,thus it was possible to note how fast and by how much jamming was established,over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities.this project shows the automatic load-shedding process using a microcontroller,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,1800 to 1950 mhztx frequency (3g),almost 195 million people in the united states had cell- phone service in october 2005,high voltage generation by using cockcroft-walton multiplier.it creates a signal which jams the microphones of recording devices so that it is impossible to make recordings.dtmf controlled home automation system.it can also be used for the generation of random numbers,1800 mhzparalyses all kind of cellular and portable phones1 w output powerwireless hand-held transmitters are available for the most different applications,noise generator are used to test signals for measuring noise figure,one of the important sub-channel on the bcch channel includes,vswr over protectionconnections.while the second one is the presence of anyone in the room,completely autarkic and mobile,the output of each circuit section was tested with the oscilloscope,while most of us grumble and move on,the project is limited to limited to operation at gsm-900mhz and dcs-1800mhz cellular band.the inputs given to this are the power source and load torque.this project shows the system for checking the phase of the supply.2100 – 2200 mhz 3 gpower supply.a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals.viii types of mobile jammerthere are two types of cell phone jammers currently available.
