GNSS1A1: 5-Minute Clean Scenario

The X-NUCLEO-GNSS1A1 GNSS expansion board from STMicroelectronics is based on the compact Teseo-LIV3F GNSS module. It provides a cost-effective and user-friendly Global Navigation Satellite System (GNSS) module. The X-NUCLEO-GNSS1A1 integrates a standalone TeseoIII single-chip positioning receiver IC, which can be used in various configurations in STM32 Nucleo projects. The Teseo-LIV3F module, with dimensions of 9.7 x 10.1 mm, offers superior accuracy achieved through its temperature-compensated 26MHz quartz oscillator (TCXO) and achieves a reduced Time-To-First-Fix (TTFF) with its dedicated 32KHz real-time clock (RTC) oscillator. To execute all GNSS operations, including collection, tracking, navigation, and data output without external memory support, the Teseo-LIV3F module operates GNSS firmware (X-CUBE-GNSS1).
