产品概述

描述

STA8090WGR belongs to Teseo III family products.

STA8090WGR is a single die standalone positioning receiver which embeds the new ST GNSS positioning engine capable of receiving signals from multiple satellite navigation systems, including GPS, Glonass, BeiDou QZSS.

The minimum BOM and small WL-CSP package make STA8090WGR the ideal solution for low-cost and small footprint products such as hand-held computers, cameras, data loggers, and sports accessories.

The device is offered with a complete GNSS firmware which performs all GNSS operations including tracking, acquisition, navigation and data output.
