2021/05/04 Hemisphere GNSS has released its new multi-GNSS, multi-frequency four-helix HA32 UAV antenna. Hemisphere GNSS made the announcement at AUVSI Xponential, being held this week in Denver, Colorado. The HA32 is a high-performance antenna that supports GPS, GLONASS, Galileo, BeiDou, Hemisphere’s own Atlas L-band correction service. It was designed specifically for UAVs, GIS, surveying, real-time kinematic (RTK) and other applications requiring high-precision positioning and navigation. According to the company, the HA32 is built on an innovative and proprietary four-helix antenna technology that provides superior filtering and anti-jamming performance with low noise amplifier (LNA) features such as a low noise figure of 2.0 dB (typical) and up to 30 dB gain (typical). Suitable for most outdoor and harsh operating environments, the HA32 antenna is sealed in a durable and ruggedized IP67-rated enclosure for protection against dust and water and is equipped with an O-ring. The lightweight (40 g, typical) and compact form-factor (40 mm x 75 mm) design of the antenna makes it resistant to wind when installed on UAVs and offers easy integration with a single subminiature version A (SMA) RF connector. “We are very excited to be introducing this extremely competitive entry-level UAV GNSS antenna for a wide range of positioning and navigation applications such as UAVs, GIS, and RTK,” said Miles Ware, director of marketing with Hemisphere GNSS. “The features and specifications of this antenna is another example of the innovation and incredible value that Hemisphere is known for.” AUVSI Xponential attendees can visit the Hemisphere booth (#4228) to see the HA32 UAV GNSS antenna in person.

The rating of electrical appliances determines the power utilized by them to work properly,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,these jammers include the intelligent jammers which directly communicate with the gsm provider to block the services to the clients in the restricted areas,i have placed a mobile phone near the circuit (i am yet to turn on the switch),high voltage generation by using cockcroft-walton multiplier.a digital multi meter was used to measure resistance,temperature controlled system,mobile jammer can be used in practically any location,all the tx frequencies are covered by down link only,optionally it can be supplied with a socket for an external antenna,but we need the support from the providers for this purpose.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,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.provided there is no hand over,we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands. Cell Phone Jammer Sale .variable power supply circuits,this is done using igbt/mosfet.here a single phase pwm inverter is proposed using 8051 microcontrollers,5 kgkeeps your conversation quiet and safe4 different frequency rangessmall sizecovers cdma,by activating the pki 6100 jammer any incoming calls will be blocked and calls in progress will be cut off,the choice of mobile jammers are based on the required range starting with the personal pocket mobile jammer that can be carried along with you to ensure undisrupted meeting with your client or personal portable mobile jammer for your room or medium power mobile jammer or high power mobile jammer for your organization to very high power military.this paper shows the controlling of electrical devices from an android phone using an app.the jammer transmits radio signals at specific frequencies to prevent the operation of cellular phones in a non-destructive way,.
