Overview
About the P20U
Specifications
The P20U is a brand-new P-series compact positioning OEM board launched by UniStrong, developed based on the Lyra II baseband chip. The P20U board tracks all-constellation, multi-frequency GNSS signals, fully supports BeiDou-3 satellite signal reception, adds support for new signals such as Galileo and QZSS, and supports BeiDou PPP.
The P20U supports standalone single-constellation operation as well as multi-constellation combined solution modes. Featuring carrier-phase RTK capability, the board supports ultra-long baseline RTK and fast initialization. Integrating multiple positioning modes including satellite-based augmentation, RTK, and SBAS, the P20U features a compact form factor and easy integration, making it widely applicable for UAVs, autonomous driving, surveying and mapping, machine control, and marine engineering.
Product Features
● Powered by Lyra II + Aquila high-precision chips; ● Full support for BeiDou-3 satellite signal reception, with all-constellation multi-frequency positioning; ● Brand-new anti-interference technology for superior performance in complex environments; ● Supports ultra-long baseline RTK and fast initialization; ● Compact form factor, low power consumption, and easy integration.
