Permanent Link to Dual-frequency GNSS smartphone supports BDS phase III signal
The latest Lenovo smartphone offers dual-frequency GNSS capable of tracking the latest BDS phase III signal, the Z6 SE, using an Allystar chipset.
The company says this is the first time a smartphone supports the new BeiDou signal.

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.
