1. A system comprising:
a device, and
a base station,
wherein the device comprises:
a memory configured to store one or more pieces of first position information and one or more first communication rates at which data is transmittable by the flight vehicle at one or more positions indicated by the one or more pieces of first position information in association with each other;
a processor configured to:
receive, from the flight vehicle, a second position information indicating a present location of the flight vehicle and a second communication rate at which the flight vehicle transmits data;
extract a first piece of the one or more pieces of first position information corresponding to one of the one or more first communication rates that is equal to or greater than the second communication rate from the memory;
when the extracted first piece of the one or more pieces of the first position information output, select a second piece of the one or more pieces of first position information corresponding to one of the one or more positions that is located between the present location of the flight vehicle and a destination of the flight vehicle, based on the second position information, out of the first piece of the one or more pieces of first position information;
control an operation of the flight vehicle by outputting the selected second piece of the one or more pieces of first position information to the flight vehicle;
select a third piece of the one or more first position information of a position on a shortest path among one or more paths from the present location to the destination, using a shortest path search method;
perform first discrimination of whether or not a predetermined base station exists on the shortest path, and when a result of the first discrimination is positive, calculate a time point at which the flight vehicle passes a position of the predetermined base station;
output a piece of time point information indicating the calculated time point; and
notify the connected predetermined base station of the piece of time point information, and

wherein the base station is configured to emit radio waves toward the sky above when the time point indicated by the piece of time point information is reached.
