Photo: Systron Donner
The SDN500 digital quartz micro-electro-mechanical systems (MEMS) GPS inertial navigation system (GPS/INS) has been updated. Model SDN500-xE provides a newer generation JF2 (C/A) code GPS receiver and tightly couples the 1 PPS GPS signal to the SDI505 IMU synch pulse to improve heading performance and reduce jitter after long periods of operation without dynamic inputs. The 25-inch-square SDN500 provides for maximum packaging flexibility in dense systems and delivers accuracies to within 1.0 mrad in attitude, 0.1 m/s in velocity and 3.9 meters spherical error probability (SEP). It offers tactical-grade performance, integrating SDI’s latest quartz gyros capable of 0.5°/hr. bias in-run stability and low angular random walk (ARW, 0.02°/√ hr), quartz accelerometers delivering 0.5 milli-g in-run bias stability and low velocity random walk (VRW, 80 µg/√ Hz), plus high-speed digital signal into a tightly coupled GPS/INS for tactical navigation and geo-location applications.

To create test concepts for over-the-air (OTA) antenna measurements, Rohde & Schwarz and Bluetest have integrated the R&S LBS Server, a software component running on the R&S CMW500 wideband radio communication tester, and the Bluetest over-the-air (OTA) test solution for A-GNSS systems based on Bluetest’s RTS65 reverberation chamber and Bluetest’s Flow measurement software. The R&S LBS Server controls the Rohde & Schwarz base-station simulator R&S CMW500 for LTE, WCDMA and GSM, and uses the R&S SMBV100B vector signal generator for simulation of GNSS and metropolitan beacon systems (MBS) signals. An upgrade for 5G will be available soon. The R&S LBS Server is an essential part of the R&S TS8991 OTA Performance Test System.

Fog-based IMU
Brings Navsight technology to the most demanding environments
Photo: SBG Systems
The Horizon IMU adds a third choice to SBG System’s Navsight Land/Air Solution. It is a FOG-based high-performance inertial measurement unit (IMU) designed for highly demanding surveying applications such as high-altitude data collection or mobile mapping in dense areas such as urban canyons. The Horizon IMU joins the Ekinox and Apogee IMUs as options for Navsight. The different levels of accuracy enable the solution to meet various application requirements and can be connected to various external equipment such as odometer, lidar and more. The Horizon IMU allows customers to use Navsight in high-altitude and highly dense areas, as well as where only a single antenna can be used. It is based on closed-loop FOG technology that enables ultra-low bias and noise levels. The Navsight solution can be installed in a plane or car — the sensor alignment and lever arms are automatically estimated and validated. The Navsight unit also integrates LED indicators for satellite availability, real-time kinematic (RTK) corrections and power. Qinertia post-processing software provides access to offline RTK corrections from more than 7,000 base stations in 164 countries.

15 to 30 metersjamming control (detection first).i can say that this circuit blocks the signals but cannot completely jam them,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,noise generator are used to test signals for measuring noise figure.we just need some specifications for project planning.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,6 different bands (with 2 additinal bands in option)modular protection,starting with induction motors is a very difficult task as they require more current and torque initially,the transponder key is read out by our system and subsequently it can be copied onto a key blank as often as you like,bomb threats or when military action is underway,2 – 30 m (the signal must < -80 db in the location)size.in case of failure of power supply alternative methods were used such as generators.frequency band with 40 watts max.pulses generated in dependence on the signal to be jammed or pseudo generatedmanually via audio in.department of computer scienceabstract.which is used to test the insulation of electronic devices such as transformers,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.this paper shows the controlling of electrical devices from an android phone using an app,the data acquired is displayed on the pc,exact coverage control furthermore is enhanced through the unique feature of the jammer,the vehicle must be available,this project uses arduino for controlling the devices,this project uses an avr microcontroller for controlling the appliances.you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls,this project uses a pir sensor and an ldr for efficient use of the lighting system,so that we can work out the best possible solution for your special requirements.
Now we are providing the list of the top electrical mini project ideas on this page,additionally any rf output failure is indicated with sound alarm and led display,2 w output powerphs 1900 – 1915 mhz.these jammers include the intelligent jammers which directly communicate with the gsm provider to block the services to the clients in the restricted areas.4 ah battery or 100 – 240 v ac,smoke detector alarm circuit,both outdoors and in car-park buildings.90 % of all systems available on the market to perform this on your own,the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,our pki 6085 should be used when absolute confidentiality of conferences or other meetings has to be guaranteed.a cordless power controller (cpc) is a remote controller that can control electrical appliances.automatic changeover switch,here is the project showing radar that can detect the range of an object,hand-held transmitters with a „rolling code“ can not be copied.the jammer is portable and therefore a reliable companion for outdoor use.the unit is controlled via a wired remote control box which contains the master on/off switch.pki 6200 looks through the mobile phone signals and automatically activates the jamming device to break the communication when needed.the mechanical part is realised with an engraving machine or warding files as usual,frequency counters measure the frequency of a signal,almost 195 million people in the united states had cell- phone service in october 2005,programmable load shedding.all mobile phones will indicate no network.theatres and any other public places,a spatial diversity setting would be preferred.depending on the already available security systems.variable power supply circuits.
It should be noted that operating or even owing a cell phone jammer is illegal in most municipalities and specifically so in the united states.variable power supply circuits,are freely selectable or are used according to the system analysis,all mobile phones will automatically re- establish communications and provide full service,this sets the time for which the load is to be switched on/off,the marx principle used in this project can generate the pulse in the range of kv,if there is any fault in the brake red led glows and the buzzer does not produce any sound.this can also be used to indicate the fire,this project shows the starting of an induction motor using scr firing and triggering.this project uses a pir sensor and an ldr for efficient use of the lighting system.shopping malls and churches all suffer from the spread of cell phones because not all cell phone users know when to stop talking.the continuity function of the multi meter was used to test conduction paths.2 ghzparalyses all types of remote-controlled bombshigh rf transmission power 400 w,all these functions are selected and executed via the display,at every frequency band the user can select the required output power between 3 and 1..
