### Instruction:

Extract the cause and effect entities from the following sentence:
This includes calibration of the differential delays between uplink (transmission from ground to reception in space) and downlink (transmission from space to reception on ground) and of the differential propagation delays in the atmosphere due to the non-reciprocal paths of uplink versus downlink
