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.

The Allystar INS Platform — the company’s latest technology — is a dual-antenna, multi-frequency, multi-GNSS inertial navigation system (INS) that delivers accurate and reliable position, velocity and orientation, the company said.
It is designed for a wide range of autonomous vehicle applications under the most demanding conditions.
The Allystar INS Platform combines high-grade, six-axis, temperature-calibrated accelerometers and gyroscopes with a multi-frequency, multi-GNSS engine, the HD9300 series. HD9300 is a dual-antenna chip-grade real-time kinematic (RTK) GNSS receiver for accurate positioning and heading.
GNSS-aided inertial navigation systems are widely used in autonomous vehicles. However, high-accuracy multi-frequency multi-GNSS receivers are usually too expensive for mass-market applications. The Allystar HD9300 series is a mass-market multi-band chip-grade receiver that concurrently support all civil bands in all GNSS constellations (GPS/QZS L1&L2&L5&L6, BDS B1&B2&B3, GAL E1&E5, GLO L1OF/L2OF) with an integrated RTK engine to achieve centimeter-level accuracy.

Fitted with a Allystar HD8040 series chipset, the Lenovo Z6 youth edition provides position accuracy up to sub-meter, according to Allystar.
The HD8040 series chipset supports all civil signals on the L5 band. Besides GPS/QZS L5 and GAL E5a, the latest BDS phase III signal B2a has already been implemented to maximize the visible satellites in L5 band.
Dual-frequency GNSS means that the receiver tracks more than one radio signal from each satellite on different frequencies — GPS L1 and L5, Galileo E1 and E5a, and Beidou B1 and B2a.
B2a will replace B2I and broadcast on MEO and IGSO satellites. The code lengths are 10230, which have better anti-cross-correlation performance and are designed separated pilot component and data component to improve tracking sensitivity.
In general navigation scenarios, multipath error lead to positioning inaccuracy of up to several meters, caused by to signals bouncing off of higher buildings. The error caused by multipath can be nullified and mitigated by using two frequencies instead of one in urban areas. Under a relatively open-sky environment, measurement error caused by the ionosphere is usually eliminated by a linear combination of dual frequencies to easily achieve sub-meter accuracy.
“Allystar is glad to boost the smartphones and Internet of Things (IoT) applications with the latest multi-frequency GNSS SoC (system on chip) technology,” said Shi Xian Yang, the product and marketing manager in Allystar.
