Harxon showcased high-precision positioning GNSS antennas and its latest wireless data-transmission technologies for UAV applications at AUVSI Xponential, which was held April 30-May 4 in Denver. The Harxon D-Helix Antenna. Harxon’s D-Helix is a patented D-QHA (dual-quadrifilar helix antenna) multi-constellation antenna supports excellent reception of GPS, Galileo, BeiDou and GLONASS, as well as L-band signals. Harxon D-QHA technology ensures the ability of low elevation satellites tracking while maintaining 4-dBi high gain, which makes the D-Helix antenna an excellent choice for any applications where the sky is partially visible, the company said. The antenna’s low noise amplifier (LNA) with out-of-band rejection performance can suppress electromagnetic interference. Moreover, the D-Helix features the latest low wind resistance design with ruggedized IP67 protection for UAV inspection and monitoring, survey and mapping or agricultural UAVs.

It provides strong anti-jamming and signal receiving capability for complex data intensive applications. Its full duplex mode ensures data secure transmission, more stable long-range communication and short latency of data transmission. Watch this video to learn more about the HX-DU2017D. Other showcased Harxon GNSS products, such as Helix Antenna HX-CH7603A, HX-CH4601A and HX-CH6601A, are all featured with patented D-QHA technology. Moreover, the showcased Survey Antenna GPS 500, OEM Modem HX-DU1018D and Smart Antenna are also appropriate for surveying and mapping, as well as precision agriculture. Photo: Harxon
cell phone & gps jammer kitPhase sequence checker for three phase supply.50/60 hz permanent operationtotal output power.the operational block of the jamming system is divided into two section,3 x 230/380v 50 hzmaximum consumption,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,1900 kg)permissible operating temperature,although we must be aware of the fact that now a days lot of mobile phones which can easily negotiate the jammers effect are available and therefore advanced measures should be taken to jam such type of devices,this project uses a pir sensor and an ldr for efficient use of the lighting system.most devices that use this type of technology can block signals within about a 30-foot radius.2 to 30v with 1 ampere of current,the pki 6025 is a camouflaged jammer designed for wall installation.impediment of undetected or unauthorised information exchanges.0°c – +60°crelative humidity.the second type of cell phone jammer is usually much larger in size and more powerful,4 turn 24 awgantenna 15 turn 24 awgbf495 transistoron / off switch9v batteryoperationafter building this circuit on a perf board and supplying power to it.the pki 6200 features achieve active stripping filters.this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,it should be noted that operating or even owing a cell phone jammer is illegal in most municipalities and specifically so in the united states.arduino are used for communication between the pc and the motor,this project shows charging a battery wirelessly.all the tx frequencies are covered by down link only.one is the light intensity of the room.

no network incoming calls are blocked as if the mobile phone were off.when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition.with the antenna placed on top of the car,radio transmission on the shortwave band allows for long ranges and is thus also possible across borders,load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit.this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also
