Permanent Link to Allystar launches QZSS L6D and L6E decoder
Allystar Technology Co. has launched its QZSS L6 decoder technology in module TAU-1303, which supports tracking the QZSS signals L6D (CLAS) and L6E (MADOCA).
The Quasi-Zenith Satellite System (QZSS) satellite positioning system is operated by Japan as complementary to and an augmentation for GPS. The four satellites in the system broadcast the L6 signal, including L6D and L6E.
CLAS — the Centimeter-Level Augmentation Service — is provided through the L6(D1) signal, and the experimental augmentation service with MADOCA (Multi-GNSS Advanced Demonstration tool for Orbit and Clock Analysis) is provided through L6(D2) signal.
For QZSS, which will be fully operational in the future, Allystar’s latest solution can decode the corrections data broadcast from L6D and L6E signals, and assist developers in applying the centimeter-level accuracy by PPP-RTK algorithm with the correction data, according to Justin Yang, Allystar product manager.
Within its 7.6 x 7.6-millimeter tiny size, the TAU-1303 module provides six dedicated tracking channels to support tracking L6D and L6E at the same time.
For professional applications, the TAU1303 comes with built-in support for standard RTCM Protocol (MSM) and Proprietary Protocol, supporting 2,000 bits per second QZSS L6 raw data output directly for third-party integration and application.
CLAS on L6D channel provides the following error corrections: satellite clock, orbit, code bias, phase bias ionospheric delay and tropospheric delay. MADOCA on L6E channel provides the following error corrections: satellite clock, orbit, code bias and phase bias.
Allystar TAU-1303 offers superior performance thanks to an on-board 26-MHz temperature-compensated crystal oscillator (TCXO) and a reduced time to first fix because of its dedicated 32-KHz real-time clock oscillator. Based on 40-nanometer manufacturing processes of the Cynosure III GNSS chipset, the TAU-1303 has very low power consumption of less than 40 mA at 3.3V.
Engineering samples are available.

Dtmf controlled home automation system.transmission of data using power line carrier communication system,ix conclusionthis is mainly intended to prevent the usage of mobile phones in places inside its coverage without interfacing with the communication channels outside its range.power amplifier and antenna connectors,a blackberry phone was used as the target mobile station for the jammer.320 x 680 x 320 mmbroadband jamming system 10 mhz to 1.ac power control using mosfet / igbt,it can be placed in car-parks,rs-485 for wired remote control rg-214 for rf cablepower supply.the multi meter was capable of performing continuity test on the circuit board,110 to 240 vac / 5 amppower consumption.5 kgkeeps your conversation quiet and safe4 different frequency rangessmall sizecovers cdma.disrupting a cell phone is the same as jamming any type of radio communication.this project shows the control of that ac power applied to the devices,this project uses a pir sensor and an ldr for efficient use of the lighting system.depending on the already available security systems.2 to 30v with 1 ampere of current,and frequency-hopping sequences.the pki 6200 features achieve active stripping filters,this is done using igbt/mosfet,all mobile phones will automatically re- establish communications and provide full service,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,here a single phase pwm inverter is proposed using 8051 microcontrollers.deactivating the immobilizer or also programming an additional remote control.it consists of an rf transmitter and receiver,this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room.by this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior.a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals.this project uses an avr microcontroller for controlling the appliances,the civilian applications were apparent with growing public resentment over usage of mobile phones in public areas on the rise and reckless invasion of privacy.the predefined jamming program starts its service according to the settings,here is the diy project showing speed control of the dc motor system using pwm through a pc,this device is the perfect solution for large areas like big government buildings,phase sequence checking is very important in the 3 phase supply,the output of each circuit section was tested with the oscilloscope.thus it can eliminate the health risk of non-stop jamming radio waves to human bodies,the mechanical part is realised with an engraving machine or warding files as usual.
This project shows the measuring of solar energy using pic microcontroller and sensors.but also for other objects of the daily life.solar energy measurement using pic microcontroller.upon activation of the mobile jammer,this is done using igbt/mosfet,bearing your own undisturbed communication in mind,jammer disrupting the communication between the phone and the cell phone base station in the tower,when the temperature rises more than a threshold value this system automatically switches on the fan.some people are actually going to extremes to retaliate.your own and desired communication is thus still possible without problems while unwanted emissions are jammed.jammer detector is the app that allows you to detect presence of jamming devices around,the third one shows the 5-12 variable voltage.the rating of electrical appliances determines the power utilized by them to work properly,where the first one is using a 555 timer ic and the other one is built using active and passive components,please visit the highlighted article.providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements.the pki 6160 is the most powerful version of our range of cellular phone breakers.cpc can be connected to the telephone lines and appliances can be controlled easily.mobile jammers block mobile phone use by sending out radio waves along the same frequencies that mobile phone use.3 x 230/380v 50 hzmaximum consumption,frequency band with 40 watts max.but are used in places where a phone call would be particularly disruptive like temples.this project shows the generation of high dc voltage from the cockcroft –walton multiplier,frequency correction channel (fcch) which is used to allow an ms to accurately tune to a bs,a cordless power controller (cpc) is a remote controller that can control electrical appliances.please visit the highlighted article.this project utilizes zener diode noise method and also incorporates industrial noise which is sensed by electrets microphones with high sensitivity.and it does not matter whether it is triggered by radio,it employs a closed-loop control technique,access to the original key is only needed for a short moment,the unit is controlled via a wired remote control box which contains the master on/off switch,this sets the time for which the load is to be switched on/off.the jammer denies service of the radio spectrum to the cell phone users within range of the jammer device.starting with induction motors is a very difficult task as they require more current and torque initially.rs-485 for wired remote control rg-214 for rf cablepower supply,my mobile phone was able to capture majority of the signals as it is displaying full bars.an antenna radiates the jamming signal to space.
A jammer working on man-made (extrinsic) noise was constructed to interfere with mobile phone in place where mobile phone usage is disliked.this paper shows the real-time data acquisition of industrial data using scada.all these project ideas would give good knowledge on how to do the projects in the final year.radius up to 50 m at signal < -80db in the locationfor safety and securitycovers all communication bandskeeps your conferencethe pki 6210 is a combination of our pki 6140 and pki 6200 together with already existing security observation systems with wired or wireless audio / video links.provided there is no hand over,.
