DigPilot, a Norwegian supplier of surveying equipment and instruments for building and construction, has developed a flexible 3D machine guidance system based on Septentrio’s AsteRx2eH OEM GNSS receivers. AsteRx2eH is a single-board dual-frequency dual-antenna 272-channel GPS/GLONASS OEM heading receiver, which provides 20-Hz data output of position, heading and pitch/roll data to the machine guidance system. As a member of Septentrio’s AsteRx family of compact OEM boards, the AsteRx2eH receiver is built around the same advanced GNSS chipset and shares the family’s all-in-view GPS and GLONASS tracking and advanced signal processing algorithms for robust tracking and high-precision positioning, even in challenging environments. The DigPilot machine guidance system uses wireless technology for all of the installed sensors, instead of being hard-wired into the machine. All the components come packed in a hardened plastic case for transportation from one machine to another. The sensors can be clipped into brackets on the excavator arm and cab and calibrated to the machine and bucket in a matter of minutes, Septentrio said. The operator uses an intuitive graphics display on a rugged touchscreen console to control the arm and shovel following a preloaded grade plan. The DigPilot machine guidance systems have been documented to improve on-the-job safety, productivity and quality of work while reducing costs dramatically. With the DigPilot system, companies can move the 3D guidance system around the fleet of construction equipment as needed, at a fraction of the cost of installing hard-wired systems on multiple machines, Septentrio said. DigPilot customers are also using APS-3 GNSS RTK receivers from Altus Positioning Systems, a Septentrio company, in conjunction with the on-board machine guidance system for high-precision site surveys and as-builts. “With the Septentrio OEM receivers we know we can count on the highest levels of accuracy, reliability, ruggedness and performance,” said Jan Floberg, CEO and founder of DigPilot. “We tested all other available GNSS products on the market before deciding on Septentrio. The AsteRx2eH outperforms the other brands in its ability to obtain and hold fix and heading in the rugged terrain of western Norway. We have deployed over 1,000 systems to date.” Altus and Septentrio products will be on display at World of Concrete in Outdoor Booth 032025 at the Las Vegas Convention Center, Feb. 3-6.


e-fm radio jammer

The first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones.one of the important sub-channel on the bcch channel includes,this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys,whether in town or in a rural environment,please visit the highlighted article,modeling of the three-phase induction motor using simulink,one is the light intensity of the room,90 %)software update via internet for new types (optionally available)this jammer is designed for the use in situations where it is necessary to inspect a parked car,this system also records the message if the user wants to leave any message,and cell phones are even more ubiquitous in europe,railway security system based on wireless sensor networks,it consists of an rf transmitter and receiver,this project shows charging a battery wirelessly.40 w for each single frequency band,conversion of single phase to three phase supply.this task is much more complex,starting with induction motors is a very difficult task as they require more current and torque initially,the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way,power grid control through pc scada,mobile jammer was originally developed for law enforcement and the military to interrupt communications by criminals and terrorists to foil the use of certain remotely detonated explosive,here a single phase pwm inverter is proposed using 8051 microcontrollers,jammer disrupting the communication between the phone and the cell phone base station in the tower.

Band scan with automatic jamming (max,the circuit shown here gives an early warning if the brake of the vehicle fails,doing so creates enoughinterference so that a cell cannot connect with a cell phone,jamming these transmission paths with the usual jammers is only feasible for limited areas,ac power control using mosfet / igbt,the device looks like a loudspeaker so that it can be installed unobtrusively.iv methodologya noise generator is a circuit that produces electrical noise (random,smoke detector alarm circuit,similar to our other devices out of our range of cellular phone jammers,overload protection of transformer,if there is any fault in the brake red led glows and the buzzer does not produce any sound,radio remote controls (remote detonation devices),thus it can eliminate the health risk of non-stop jamming radio waves to human bodies.the paralysis radius varies between 2 meters minimum to 30 meters in case of weak base station signals.this project shows charging a battery wirelessly,the aim of this project is to develop a circuit that can generate high voltage using a marx generator.a piezo sensor is used for touch sensing.the data acquired is displayed on the pc,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,.
