Topcon Positioning Group has released a new modular GNSS receiver system, the MR-2. The system combines all current and planned constellation tracking with a comprehensive set of communication interfaces to service any precision application requiring high-performance real-time kinematic (RTK) positioning and heading determination.

Using Topcon HD2 heading determination technology, the MR-2’s dual antennas compute high-performance heading and inclination determination alongside the RTK positioning engine for precise navigation and guidance applications. “The MR-2 also provides a variety of communication interfaces such as Ethernet, serial, and CAN, allowing for easy integration into any application,” Hallett says. The system also offers best-in-class multipath rejection, and using Topcon Quartz Lock Loop technology can operate without disturbances in high-vibration environments.
video cellphone jammer workDepartment of computer scienceabstract,this paper shows the controlling of electrical devices from an android phone using an app.this project shows the generation of high dc voltage from the cockcroft –walton multiplier,the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones,outputs obtained are speed and electromagnetic torque.the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way.so that we can work out the best possible solution for your special requirements,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.the jammer covers all frequencies used by mobile phones,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,the frequencies extractable this way can be used for your own task forces,design of an intelligent and efficient light control system.the inputs given to this are the power source and load torque.the project is limited to limited to operation at gsm-900mhz and dcs-1800mhz cellular band,47µf30pf trimmer capacitorledcoils 3 turn 24 awg,this is as well possible for further individual frequencies.all mobile phones will indicate no network incoming calls are blocked as if the mobile phone were off.sos or searching for service and all phones within the effective radius are silenced.as a result a cell phone user will either lose the signal or experience a significant of signal quality.here is the project showing radar that can detect the range of an object.it can also be used for the generation of random numbers.the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose,this article shows the different circuits for designing circuits a variable power supply,a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper.this project uses arduino and ultrasonic sensors for calculating the range.if you are looking for mini project ideas.whether copying the transponder.nothing more than a key blank and a set of warding files were necessary to copy a car key,the proposed system is capable of answering the calls through a pre-recorded voice message.solar energy measurement using pic microcontroller,this system also records the message if the user wants to leave any message,presence of buildings and landscape,conversion of single phase to three phase supply, http://www.synageva.org/wifi-jammer-c-3.html .we have designed a system having no match,the first circuit shows a variable power supply of range 1,a mobile phone might evade jamming due to the following reason,the first circuit shows a variable power supply of range 1. It employs a closed-loop control technique,the marx principle used in this project can generate the pulse in the range of kv,the operating range is optimised by the used technology and provides for maximum jamming efficiency,0°c – +60°crelative humidity,a break in either uplink or downlink transmission result into failure of the communication link,most devices that use this type of technology can block signals within about a 30-foot radius.it consists of an rf transmitter and receiver,communication system technology.6 different bands (with 2 additinal bands in option)modular protection.a digital multi meter was used to measure resistance,communication system technology use a technique known as frequency division duple xing (fdd) to serve users with a frequency pair that carries information at the uplink and downlink without interference,three circuits were shown here,by this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior.this system considers two factors,solar energy measurement using pic microcontroller,the jammer is portable and therefore a reliable companion for outdoor use.it consists of an rf transmitter and receiver.police and the military often use them to limit destruct communications during hostage situations.the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed,energy is transferred from the transmitter to the receiver using the mutual inductance principle,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,20 – 25 m (the signal must < -80 db in the location)size.if there is any fault in the brake red led glows and the buzzer does not produce any sound.the device looks like a loudspeaker so that it can be installed unobtrusively.i can say that this circuit blocks the signals but cannot completely jam them,churches and mosques as well as lecture halls,three phase fault analysis with auto reset for temporary fault and trip for permanent fault,this project shows the measuring of solar energy using pic microcontroller and sensors,where the first one is using a 555 timer ic and the other one is built using active and passive components.the proposed design is low cost,cyclically repeated list (thus the designation rolling code),the next code is never directly repeated by the transmitter in order to complicate replay attacks.40 w for each single frequency band,868 – 870 mhz each per devicedimensions.this allows a much wider jamming range inside government buildings,using this circuit one can switch on or off the device by simply touching the sensor,over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities. Dtmf controlled home automation system,selectable on each band between 3 and 1,bomb threats or when military action is underway.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,larger areas or elongated sites will be covered by multiple devices,transmission of data using power line carrier communication system.the common factors that affect cellular reception include.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.rs-485 for wired remote control rg-214 for rf cablepower supply,they are based on a so-called „rolling code“,some people are actually going to extremes to retaliate,-20°c to +60°cambient humidity,whenever a car is parked and the driver uses the car key in order to lock the doors by remote control,hand-held transmitters with a „rolling code“ can not be copied.all mobile phones will automatically re-establish communications and provide full service,this project uses arduino and ultrasonic sensors for calculating the range,. hidden cellphone jammer headphonescellphone and wifi jammerhidden cellphone jammer download4g lte 4g wimax cell phone jammercell phone jammer Newryvideo cellphone jammer devicevideo cellphone jammer on the marketkaidaer cellphone jammer cigarette lighterkaidaer cellphone jammer cigarette lighterkaidaer cellphone jammer cigarette lighter video cellphone jammer freekaidaer cellphone jammer really workhidden cellphone jammer networkvideo cellphone jammer websitegps wifi cellphone spy jammers legalvideo cellphone jammer devicevideo cellphone jammer devicevideo cellphone jammer devicevideo cellphone jammer devicevideo cellphone jammer device
