To support future Multi-Domain Operations analyses, the DEVCOM Analysis Center DAC is exploring ways to represent the contribution of space-based Intelligence, Surveillance, and Reconnaissance assets in the Armys combat simulations. DAC is using the Framework for Capability-based Tactical Analysis Libraries and Simulations FRACTALS as a test-bed for methodology development. As a start, the Simplified General Perturbations 4 algorithm for predicting the orbital path of satellites has been incorporated into FRACTALS. This report focuses on imagery products available from commercial satellite constellations with resolutions of 1 m or less. Methods of predicting resolution as a function of sensor characteristics, slant range including curvature of Earth, and viewing angle are presented. Examples of what can be perceived at various resolutions are also discussed.
