The StealthTransit system is installed onto the telescope. It allows users to interrupt camera exposure while satellites transit through the telescope's field of view without changing the camera photosensor's mode of operation.
In this way, StealthTransit prevents sunlight reflected from the satellite from entering the camera's photosensor.
The StealthTransit system is intended for use with long exposure photography when interruption of exposure for fractions or units of seconds does not significantly affect overall exposure time or the quality of the resulting image.
The exposure is interrupted by means of StealthTransit's additional shutter, located in front of the telescope's camera, or by means of the telescope's own shutter if it is able to work autonomously from the sensor (performing short-term switching without interrupting the photosensor's integration mode).
The shutter closes and opens in response to commands from the control unit. The control unit receives satellite trajectory data through two channels:
1. From Space Situational Awareness (SSA) data through the SSA Connector
2. Observing and recognizing bright satellites using the telescope-detector
The detection of bright satellites, trajectory analysis and calculating their time of their entry and exit from the telescope's field of view are performed by the StealthTransit Predictor program.
