说明：The XLGPS88-40 combines the STMicroelectronics flexible and high sensitivity STA8088FG (Teseo-II) GPS / Galileo / GLONASS baseband chip with the STA5620 Low Power GPS RF front end to form a complete high GPS receiver performance module.

说明：MT3339 has high-performance single-chip GPS solution which includes on-chip CMOS RF, digital baseband, ARM7 CPU and an embedded flash (optional). It is able to achieve the industry's highest level of sensitivity, accuracy and Time-to-First-Fix (TTFF) with the lowest power consumption in a small-footprint lead-free package.

说明：The NEO-M8 series of standalone concurrent GNSS modules is built on the exceptional performance of the u-blox M8 GNSS (GPS, GLONASS, BeiDou, QZSS, SBAS and Galileo-ready1) engine in the industry proven NEO form factor. The NEO-M8 series provides high sensitivity and minimal acquisition times while maintaining low system power. The NEO-M8M is optimized for cost sensitive applications, while NEO-M8N/M8Q provides best performance and easier RF integration. The NEO form factor allows easy migration from previous NEO generations. Sophisticated RF-architecture and interference suppression ensure maximum performance even in GNSS-hostile environments. The NEO-M8 series combines a high level of robustness and integration capability with flexible connectivity options. The future-proof NEO-M8N includes an internal Flash that allows simple firmware upgrades for supporting additional GNSS systems. This makes NEO-M8 perfectly suited to industrial and automotive applications.

说明：STA2058 is the high-sensitivity baseband of TESEO GPS platform which include the STA5620 RF Front-End. The embedded Flash memory enables the equipment manufacturer to load the entire GPS software (including tracking, acquisition, navigation and data output) after customizing its interfaces to his needs. A standard GPS library is available from ST.

说明：The chip is a fully integrated RF front-end able to down-convert the GPS L1 signal from 1575.42MHz to 4.092MHz. The IF signal is converted by a two bit ADC. Sign (SIGN), Magnitude (MAG) and the 16.368MHz sampling clock (GPS_CLK) are provided to the baseband.
