Small secondary space payloads, in particular cubesats, deployed from a launch vehicle pose resource and processing problems for conventional space situational awareness network (SSN) systems. Cubesats do not have the ability to tip and cue the network with ephemeris data at the time of deployment. Typically the SSN needs days to weeks to establish credible cubesat ephemerides before the cubesat can become operational. Advanced Scientific Concepts (ASC) is a provider of space-based 3D Flash LIDAR cameras for proximal satellite and space situational awareness applications. ASC is proposing to develop a state-of-the-art Flash LIDAR sensor that detects, classifies, and tracks cubesats at the time of launch vehicle deployment. The sensor has the ability to calculate the appropriate cubesat ephemerides to tip and cue a SSN. The data is transmitted to the SSN via an appropriate launch vehicle-to-earth-to-SSN data link. The Phase I effort defines a reference CONOPS, sensor requirements and develops a 3D Flash LIDAR sensor architecture.Flash LIDAR,Sensor,Cubesat,ephemeris,space,situational awareness
