Tesseract is a four-channel coherent SDR — the base module behind ARGUS and AeroArgus. It calibrates automatically when needed, maintaining the coherence direction finding requires. 300 MHz – 6 GHz range, 65 MHz instantaneous bandwidth. A REST API returns processed data — engineers get ready-to-use output for radio-intelligence and geolocation tasks without handling the raw signal. Build your own system on a proven platform.
