Analysis of Alternatives tools, and Predictive Atmospheric Specification
Real-Time Ionospheric Predictions
ASTRA™ develops software tools to quantify the impact of various measurements for both ionospheric and thermospheric specification. These tools enable vital ‘Analysis of Alternatives’ exercises, and help to maximize the utility of new sensors through OSSE experiments. Millions of dollars in savings can be realized by preventing deployment of unnecessary or redundant sensors.
Real-time ionospheric predictions also provide an alternative solution for raytracing applications and simulation of TID effects for geolocation. Additionally, real-time thermospheric neutral density predictions enable accurate satellite orbit prediction and analysis.
TIDDBIT HF Sounder
ASTRA™ has cutting-edge technologies for mapping Traveling Ionospheric Disturbances in the F-region ionosphere focuses on complete characterization of these waves. Large TIDs can cause errors in operational systems employing GPS, radar, and radio. Data from our TIDDBIT HF sounder technology makes it possible to sense and reconstruct the angular displacement of radio reflection surfaces to aid with real-time PNT compensation adjustments. We are growing a global network to provide world-wide mapping for our customers.
ASTRA’s TIDDBIT HF sounder is a dual-frequency HF Doppler system that can detect and characterize waves propagating through the ionosphere. Using spaced transmitters and receivers operating at multiple frequencies, this unique instrument resolves both horizontal and vertical propagation characteristics.
