Abstract
The present disclosure relates to methods and apparatuses for reducing propagation delay uncertainty while conducting a survey. The apparatus includes a plurality of nodes along a communication path configured to allow communication between nodes with only one clock domain boundary crossing. Each node may include a clock, a memory, and a processor. The plurality of nodes is arranged in a linear topology. The linear topology may have first and second nodes on the ends of the line. The method may include reducing propagation delay uncertainty using at least one time marker transmitted to each of the plurality of nodes without crossing a clock domain boundary of any other node.
