DORT Technology
Dynamic Optical Ranging & Timing (DORT) is a disruptive technology for high precise and absolute distance measurement. Besides ranging, this innovation can be used for optical time synchronisation as well as for communication.
This technological breakthrough allows a multitude of applications. In addition to use as a cost-effective CubeSat payload for formation flights, there are also applications in the terrestrial area. This includes large volume metrology, time synchronisation and vibration measurements in an exceptional performance.
