摘要
Aspects herein describe techniques for synchronizing clocks between two moving platforms (e.g., land vehicles, ships, aircraft, and the like) using optical signals generated from lasers. In one aspect, a method for mixing an intermediate signal with a local reference clock in a method of communicating between moving platforms includes mixing the intermediate signal with a sine representation of the local reference clock to generate a first offset error; mixing the intermediate signal with a cosine representation of the local reference clock to generate a second offset error; and combining the first and second offset errors to generate the fine phase offset.
