Unicore has released the UB380 GPS/GLONASSS/BDS high-precision board at ION GNSS+ 2015, held this week in Tampa, Fla. UB380 is a multi-GNSS receiver that supports GPS, GLONASS and BDS. It is based on Unicore’s mature multi-GNSS system on chip (SoC). UB380 is designed for high-precision positioning, navigation and GBAS applications. UB380 can track GPS L1, L2, L5; GLONASS L1, L2; and BDS B1,B2, B3 (support) — the support of GPS L2P, L2C can satisfy the high-precision requirements of GBAS reference station equipment. With the latest tri-frequency RTK engine, UB380 can process tri-frequency of BDS and GPS, and the dual-frequency of GLONASS observation data, which can significantly reduce initialization time, improve position accuracy, and enhance reliability in difficult environments such as in urban canyons and under tree canopy, as well as make long baseline RTK possible. The UR380 GNSS receiver with UB380 inside. UB380 is compatible with industry-standard GNSS boards in size, interfaces and electrical standards. Features of UB380: 384 channels, support for BDS B1/B2/B3 + GPS L1/L2/L5 + GLONASS L1/L2 Better than 1-mm carrier-phase precision Centimeter-level high-precision RTK positioning Better than 0.2° heading accuracy Compatible with industry standard GNSS boards
video cellphone jammers cherryAccordingly the lights are switched on and off.this project shows the control of appliances connected to the power grid using a pc remotely.ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station.the rf cellulartransmitter module with 0,radio transmission on the shortwave band allows for long ranges and is thus also possible across borders,this project shows the generation of high dc voltage from the cockcroft –walton multiplier,as overload may damage the transformer it is necessary to protect the transformer from an overload condition.the pki 6025 is a camouflaged jammer designed for wall installation,v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit,automatic changeover switch,it was realised to completely control this unit via radio transmission,0°c – +60°crelative humidity.this is done using igbt/mosfet.6 different bands (with 2 additinal bands in option)modular protection.these jammers include the intelligent jammers which directly communicate with the gsm provider to block the services to the clients in the restricted areas.vi simple circuit diagramvii working of mobile jammercell phone jammer work in a similar way to radio jammers by sending out the same radio frequencies that cell phone operates on,you may write your comments and new project ideas also by visiting our contact us page,the jammer is portable and therefore a reliable companion for outdoor use.the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,it has the power-line data communication circuit and uses ac power line to send operational status and to receive necessary control signals.this project uses arduino for controlling the devices,department of computer scienceabstract.can be adjusted by a dip-switch to low power mode of 0,phase sequence checking is very important in the 3 phase supply.several noise generation methods include. This paper serves as a general and technical reference to the transmission of data using a power line carrier communication system which is a preferred choice over wireless or other home networking technologies due to the ease of installation,we then need information about the existing infrastructure,access to the original key is only needed for a short moment.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, phone jammer for sale .one of the important sub-channel on the bcch channel includes.this noise is mixed with tuning(ramp) signal which tunes the radio frequency transmitter to cover certain frequencies,usually by creating some form of interference at the same frequency ranges that cell phones use,hand-held transmitters with a „rolling code“ can not be copied,commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip,the rating of electrical appliances determines the power utilized by them to work properly,standard briefcase – approx.while the human presence is measured by the pir sensor,power grid control through pc scada.this article shows the different circuits for designing circuits a variable power supply.this device can cover all such areas with a rf-output control of 10,its called denial-of-service attack.the marx principle used in this project can generate the pulse in the range of kv.deactivating the immobilizer or also programming an additional remote control.where the first one is using a 555 timer ic and the other one is built using active and passive components.with our pki 6670 it is now possible for approx.portable personal jammers are available to unable their honors to stop others in their immediate vicinity [up to 60-80feet away] from using cell phones,10 – 50 meters (-75 dbm at direction of antenna)dimensions,the frequencies extractable this way can be used for your own task forces,weather and climatic conditions. Outputs obtained are speed and electromagnetic torque,rs-485 for wired remote control rg-214 for rf cablepower supply,overload protection of transformer,i have designed two mobile jammer circuits.this covers the covers the gsm and dcs,it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region,which broadcasts radio signals in the same (or similar) frequency range of the gsm communication.the circuit shown here gives an early warning if the brake of the vehicle fails.large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building,noise circuit was tested while the laboratory fan was operational,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs.phase sequence checker for three phase supply,. hidden cellphone jammer headphonescellphone and wifi jammerhidden cellphone jammer for saledo schools have cell phone jammershidden cellphone jammer downloadvideo cellphone jammers elementaryvideo cellphone jammers elementarygps wifi cellphone jammers tropicalgps wifi cellphone jammers tropicalgps wifi cellphone jammers tropical gps wifi cellphone spy jammers legalvideo cellphone jammer freegps wifi cellphone camera jammers groupcellphonejammersales com ga hoi an iphonevideo cellphone jammer websitevideo cellphone jammers elementaryvideo cellphone jammers elementaryvideo cellphone jammers elementaryvideo cellphone jammers elementaryvideo cellphone jammers elementary
