DELTA CODING FOR REMOTE SENSING Russian patent published in 2023 - IPC H04B7/19 

FIELD: remote sensing systems; delta coding technologies for remote sensing.

SUBSTANCE: invention is aimed to ensure that information is updated more efficiently, more frequently, more quickly, or more reliably. It is achieved by the fact that a system that allows remote sensing of signals can have processing capabilities that make it possible to determine the differences between the sensing signals and the basic state, for example, a base map of information. Certain differences from the baseline may be transmitted over a communication link (for example, wireless link, satellite link) and may be referred to as "delta coding" or may be otherwise associated with "delta coding" of the information recorded by the remote sensing system. In some examples, delta coding may allow a smaller amount of information to be transmitted over the link instead of the entire received sensing signals to be transmitted.

EFFECT: information is updated more efficiently, more frequently, more quickly, or more reliably
