AlfaCrux Telemetry Viewer

The AlfaCrux Telemetry Viewer is a web platform developed and provided by the AlfaCrux team to make easier and immediate for all users to see and understand the meaning and purpose of the AlfaCrux downlink signal in accordance with the amateur-satellite service. All frames available online are properly associated with the call sign responsible for the information, allowing the amateur radio to search our databank for his specific contribution in the AlfaCrux mission. 

This web data system is also part of an innovative framework under development by the AlfaCrux team to assist the development and operation of nanosatellites. By innovative framework we mean a new architecture in which the development of a high-fidelity digital model of the nanosatellite is considered. In this innovative approach, the digital model is constantly under improvements based on the data collection system (laboratory tests, computer simulations, and in-orbit data), and more than that, the digital model may be able to improve and update the satellite on orbit. In other words, we are proposing a digital twin framework for nanosatellite mission applications. Come and be part of this within the AlfaCrux mission!
