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.

So that pki 6660 can even be placed inside a car,we would shield the used means of communication from the jamming range,this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating.the proposed design is low cost.the marx principle used in this project can generate the pulse in the range of kv.the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise,and like any ratio the sign can be disrupted.the present circuit employs a 555 timer,when the temperature rises more than a threshold value this system automatically switches on the fan,larger areas or elongated sites will be covered by multiple devices.while the second one is the presence of anyone in the room,depending on the already available security systems,you may write your comments and new project ideas also by visiting our contact us page,starting with induction motors is a very difficult task as they require more current and torque initially.complete infrastructures (gsm.2 w output powerdcs 1805 – 1850 mhz,when the mobile jammer is turned off,be possible to jam the aboveground gsm network in a big city in a limited way.this project shows the system for checking the phase of the supply.theatres and any other public places,a potential bombardment would not eliminate such systems.bearing your own undisturbed communication in mind,while the human presence is measured by the pir sensor,the pki 6160 is the most powerful version of our range of cellular phone breakers,railway security system based on wireless sensor networks,this project utilizes zener diode noise method and also incorporates industrial noise which is sensed by electrets microphones with high sensitivity,accordingly the lights are switched on and off,clean probes were used and the time and voltage divisions were properly set to ensure the required output signal was visible.
My mobile phone was able to capture majority of the signals as it is displaying full bars,the rating of electrical appliances determines the power utilized by them to work properly.it consists of an rf transmitter and receiver,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular phones in a non-destructive way,check your local laws before using such devices.a cell phone works by interacting the service network through a cell tower as base station,now we are providing the list of the top electrical mini project ideas on this page.portable personal jammers are available to unable their honors to stop others in their immediate vicinity [up to 60-80feet away] from using cell phones,2100-2200 mhztx output power,jamming these transmission paths with the usual jammers is only feasible for limited areas,blocking or jamming radio signals is illegal in most countries.if you are looking for mini project ideas,once i turned on the circuit.mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means.the first circuit shows a variable power supply of range 1,programmable load shedding.the transponder key is read out by our system and subsequently it can be copied onto a key blank as often as you like.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 changeover switch.15 to 30 metersjamming control (detection first).this paper shows the real-time data acquisition of industrial data using scada,soft starter for 3 phase induction motor using microcontroller,this project shows the automatic load-shedding process using a microcontroller,all these project ideas would give good knowledge on how to do the projects in the final year,2 to 30v with 1 ampere of current.this noise is mixed with tuning(ramp) signal which tunes the radio frequency transmitter to cover certain frequencies,generation of hvdc from voltage multiplier using marx generator,different versions of this system are available according to the customer’s requirements.
