Artemis is a software designed to assist radio frequency (RF) signal identification and storage. It simplifies real-time spectrum analysis by leveraging one of the most extensive and community-driven databases, containing over 500 recognized signals. This comprehensive software solution allows users to collect RF signals with specific parameters such as frequency, bandwidth, modulation, etc. Users can also store spectrum waterfalls, audio samples, and all types of documents for future reference. Artemis provides a robust platform to manage a wide range of RF data with precision and ease.
Artemis enhances RF propagation analysis with comprehensive space weather tracking. It offers near real-time (5-minute) data and forecasts to help users anticipate the effects of solar and geomagnetic conditions on RF communications.
