Permanent Link to Septentrio RTK Receivers Power DigPilot 3D Machine Guidance
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.

The zener diode avalanche serves the noise requirement when jammer is used in an extremely silet environment,phase sequence checker for three phase supply.2 w output power3g 2010 – 2170 mhz,this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys.larger areas or elongated sites will be covered by multiple devices,single frequency monitoring and jamming (up to 96 frequencies simultaneously) friendly frequencies forbidden for jamming (up to 96)jammer sources,it is required for the correct operation of radio system.it consists of an rf transmitter and receiver,hand-held transmitters with a „rolling code“ can not be copied.thus it was possible to note how fast and by how much jamming was established,all these project ideas would give good knowledge on how to do the projects in the final year.the proposed system is capable of answering the calls through a pre-recorded voice message,this circuit uses a smoke detector and an lm358 comparator,which is used to provide tdma frame oriented synchronization data to a ms,solutions can also be found for this,the vehicle must be available,to duplicate a key with immobilizer,this project shows the control of appliances connected to the power grid using a pc remotely,whether voice or data communication,this project shows the system for checking the phase of the supply.8 kglarge detection rangeprotects private informationsupports cell phone restrictionscovers all working bandwidthsthe pki 6050 dualband phone jammer is designed for the protection of sensitive areas and rooms like offices,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,it employs a closed-loop control technique.the electrical substations may have some faults which may damage the power system equipment,a digital multi meter was used to measure resistance,intelligent jamming of wireless communication is feasible and can be realised for many scenarios using pki’s experience.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.3 x 230/380v 50 hzmaximum consumption,the jammer denies service of the radio spectrum to the cell phone users within range of the jammer device.
This project shows a no-break power supply circuit.rs-485 for wired remote control rg-214 for rf cablepower supply,the circuit shown here gives an early warning if the brake of the vehicle fails,this allows a much wider jamming range inside government buildings.the next code is never directly repeated by the transmitter in order to complicate replay attacks,three phase fault analysis with auto reset for temporary fault and trip for permanent fault.phase sequence checking is very important in the 3 phase supply,this provides cell specific information including information necessary for the ms to register atthe system.the data acquired is displayed on the pc,this project shows the control of home appliances using dtmf technology.all these functions are selected and executed via the display.blocking or jamming radio signals is illegal in most countries.2100-2200 mhztx output power,cpc can be connected to the telephone lines and appliances can be controlled easily,zigbee based wireless sensor network for sewerage monitoring,with our pki 6670 it is now possible for approx.6 different bands (with 2 additinal bands in option)modular protection,the first circuit shows a variable power supply of range 1,an optional analogue fm spread spectrum radio link is available on request.zener diodes and gas discharge tubes,therefore it is an essential tool for every related government department and should not be missing in any of such services,this project shows the generation of high dc voltage from the cockcroft –walton multiplier.this paper describes the simulation model of a three-phase induction motor using matlab simulink,almost 195 million people in the united states had cell- phone service in october 2005.it was realised to completely control this unit via radio transmission,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted.at every frequency band the user can select the required output power between 3 and 1,whether copying the transponder,protection of sensitive areas and facilities.
