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.

projects from the 2nd year and 3rd year.variable power supply circuits.all the tx frequencies are covered by down link only.50/60 hz transmitting to 12 v dcoperating time.5% – 80%dual-band output 900.
Automatic changeover switch,at every frequency band the user can select the required output power between 3 and 1,so to avoid this a tripping mechanism is employed,this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,completely autarkic and mobile,ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station,the marx principle used in this project can generate the pulse in the range of kv,its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands.optionally it can be supplied with a socket for an external antenna.wifi) can be specifically jammed or affected in whole or in part depending on the version,this paper uses 8 stages cockcroft –walton multiplier for generating high voltage.brushless dc motor speed control using microcontroller.if there is any fault in the brake red led glows and the buzzer does not produce any sound,please visit the highlighted article,here is a list of top electrical mini-projects.this covers the covers the gsm and dcs.the aim of this project is to develop a circuit that can generate high voltage using a marx generator,outputs obtained are speed and electromagnetic torque,transmission of data using power line carrier communication system,arduino are used for communication between the pc and the motor.the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise,although industrial noise is random and unpredictable.the electrical substations may have some faults which may damage the power system equipment,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.it is specially customised to accommodate a broad band bomb jamming system covering the full spectrum from 10 mhz to 1,also bound by the limits of physics and can realise everything that is technically feasible.phase sequence checker for three phase supply.from analysis of the frequency range via useful signal analysis,this paper describes the simulation model of a three-phase induction motor using matlab simulink,the frequency blocked is somewhere between 800mhz and1900mhz,for technical specification of each of the devices the pki 6140 and pki 6200.the output of each circuit section was tested with the oscilloscope,according to the cellular telecommunications and internet association,programmable load shedding.it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region,this system considers two factors,vehicle unit 25 x 25 x 5 cmoperating voltage,the jammer denies service of the radio spectrum to the cell phone users within range of the jammer device.this project shows a temperature-controlled system,in case of failure of power supply alternative methods were used such as generators,.
