Claim:
1. A system comprising: a ground station; at least one airborne measurement device; and an airborne device tethered to the ground station using at least one wire that maintains the airborne device in line of sight with the ground station, wherein the airborne device is configured to communicate with the at least one airborne measurement device including sending in a multiplexed manner each of the at least one airborne measurement device a planned route information in parts by: aligning a directional antenna of the airborne device with a starting position of a first airborne measurement device and instruct the first airborne measurement device to proceed to a first pre-determined position; aligning the directional antenna of the airborne device with a starting position of at least one other airborne measurement device and instruct the at least one other airborne measurement device to proceed to at least one other first pre-determined position aligning the directional antenna with the first pre-determined position of the first airborne measurement device and instructing the first measurement device to proceed to a next pre-determined position; aligning the directional antenna with the at least one other first pre-determined position and instructing the at least one other airborne measurement device to proceed to at least one other next pre-determined position; and wherein upon a loss of the line of sight with the at least one airborne measurement device, the airborne device is configured to determine a next pre-determined position of the at least one airborne measurement device and reposition the directional antenna in a direction of the next pre-determined position of the at least one airborne measurement device.
