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.
