1. A position control apparatus of an unmanned marine observation device, the position control apparatus comprising:
a first position control apparatus and a second position control apparatus,
wherein the first position control apparatus comprises:
a first main body part comprising a first hollow portion into which a first unmanned marine observation device is coupled;
a first movement part extending outward from the first main body part and configured to move the first unmanned marine observation device in the ocean, wherein the first movement part comprises a plurality of first propellers configured to generate power for moving the first unmanned marine observation device to a first pre-determined position and maintaining the first unmanned marine observation device at the pre-determined position;
a first GPS signal receiver configured to receive a first GPS signal and produce position information on the basis of the first GPS signal; and
a first controller configured to control an operation of the first movement part on the basis of the first GPS signal,
wherein the second position control devise comprises:
a second main body part comprising a second hollow portion into which a second unmanned marine observation device is coupled;
a second movement part extending outward from the second main body part and configured to move the second unmanned marine observation device in the ocean, wherein the second movement part comprises a plurality of second propellers configured to generate power for moving the second unmanned marine observation device to a second pre-determined position and maintaining the second unmanned marine observation device at the second pre-determined position;
a second GPS signal receiver configured to receive a second GPS signal and produce position information on the basis of the second GPS signal; and
a second controller configured to control an operation of the second movement part on the basis of the second GPS signal,
wherein the first position control apparatus and the second position control apparatus are wirelessly and communicatively coupled to each other, and
wherein the first controller and the second controller are configured to operate the first movement part and the second movement part to maintain a pre-determined distance between the first unmanned marine observation device and the second unmanned observation device.
