 ## Overview
 Web-FIK is a sophisticated toolkit for rapid visualization of data from stratospheric balloons, utilizing multiple communication channels, specifically SiK with MAVLINK packets and Lora TTN. It extracts data from the TTN network and from scripts in tracking vehicles that receive Sik packets (mavlink) using ISM02A or TFSIK modems. The data is immediately sent to a server, visualized, and forwarded to amateur.sondehub.org.
