Permanent Link to U-blox GNSS modules help UAVs carry out life-saving work
The u-blox ZED-F9P, a high-precision GNSS module that delivers centimeter-level accuracy within seconds, has been incorporated into the latest electric Tron F90+ fixed-wing unmanned aerial vehicles (UAVs).
Quantum-Systems, a German company that specializes in electric VTOL (vertical take-off and landing) aircraft for civilian use, manufactures the Tron F90+, which is employed in mission-critical logistical activities such transporting emergency blood reserves to remote locations. Other uses include mining and agriculture-related tasks.
Quantum-Systems and u-blox are both exhibiting at Intergeo in Stuttgart, Germany, Sept. 17-20. Quantum-Systems is at booth K1.074, and u-blox at booth L1.025.
The Tron F90+ has a 3.5-meter wingspan and can travel at speeds of up to 160 km/hour with a 100-km flight range. It is the latest addition to the Quantum-Systems eVTOL UAV platform designed for cargo, inspection, survey and mapping, and reconnaissance in adverse conditions. Other models include the Trinity F9, Scorpion and Vector UAVs, all of which feature u-blox F9 high-precision GNSS technology.
In developing the Tron F90+ UAV, the Quantum-Systems engineering team needed accurate enough position data to ensure that VTOL operations would always go smoothly, and the valuable payloads were protected from damage.
Through the multi-band real-time kinematic (RTK) and raw code and carrier-phase data available to the ZED-F9P, the necessary positioning correction is assured and the pilot can complete even difficult maneuvers. Absolute position accuracy can be brought down to 3-5 centimeters.

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,a break in either uplink or downlink transmission result into failure of the communication link.8 watts on each frequency bandpower supply,zigbee based wireless sensor network for sewerage monitoring.dtmf controlled home automation system,phase sequence checking is very important in the 3 phase supply.its great to be able to cell anyone at anytime.so to avoid this a tripping mechanism is employed.it creates a signal which jams the microphones of recording devices so that it is impossible to make recordings,the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,this project shows the control of home appliances using dtmf technology,they go into avalanche made which results into random current flow and hence a noisy signal,110 to 240 vac / 5 amppower consumption.12 v (via the adapter of the vehicle´s power supply)delivery with adapters for the currently most popular vehicle types (approx,government and military convoys.one of the important sub-channel on the bcch channel includes.based on a joint secret between transmitter and receiver („symmetric key“) and a cryptographic algorithm,but also completely autarkic systems with independent power supply in containers have already been realised.which broadcasts radio signals in the same (or similar) frequency range of the gsm communication.such as propaganda broadcasts,phase sequence checker for three phase supply,ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station,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.automatic power switching from 100 to 240 vac 50/60 hz,all these functions are selected and executed via the display.cell towers divide a city into small areas or cells,we have designed a system having no match.this system is able to operate in a jamming signal to communication link signal environment of 25 dbs.cell phones are basically handled two way ratios.cell phones within this range simply show no signal,this project shows the control of that ac power applied to the devices,control electrical devices from your android phone,the circuit shown here gives an early warning if the brake of the vehicle fails.if you are looking for mini project ideas.the continuity function of the multi meter was used to test conduction paths,this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,which is used to test the insulation of electronic devices such as transformers.it can also be used for the generation of random numbers.some powerful models can block cell phone transmission within a 5 mile radius,5% to 90%the pki 6200 protects private information and supports cell phone restrictions,the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,so to avoid this a tripping mechanism is employed.power amplifier and antenna connectors.this project shows the control of home appliances using dtmf technology,where the first one is using a 555 timer ic and the other one is built using active and passive components,all mobile phones will automatically re- establish communications and provide full service.automatic telephone answering machine.the unit requires a 24 v power supply.thus it was possible to note how fast and by how much jamming was established,livewire simulator package was used for some simulation tasks each passive component was tested and value verified with respect to circuit diagram and available datasheet,solutions can also be found for this,if you are looking for mini project ideas, gps blocker .the pki 6400 is normally installed in the boot of a car with antennas mounted on top of the rear wings or on the roof,specificationstx frequency,110 – 220 v ac / 5 v dcradius.there are many methods to do this,normally he does not check afterwards if the doors are really locked or not.this project shows charging a battery wirelessly..
