Aspects herein describe techniques for synchronizing clocks between two moving platforms using optical signals generated from lasers to measure clock offsets and determine a separation distance between moving platforms. Once the clocks are synchronized (e.g., an offset between the clocks is determined), the moving platforms can share sensor data, location data, and other information which is dependent on accurate timestamps and relative positions. In one aspect, one of the platforms serves as a virtual mirror. That is, the platform transmits a pulse at the same instance a pulse is received, similar to a mirror that reflects incident light. For example, the first platform may transmit pulses which are received at the second platform. The second platform can use optical or electrical components to form the virtual mirror that transmits an optical pulse to the first platform each time a pulse is received at the second platform.
