Correct Answer

(1) Weather information system
(2) Control system
(3) Satellite

Explanation

The system context diagram for the weather station shows three external systems in its environment: the Weather information system (which receives weather data), the Control system (which issues control commands), and the Satellite (used as the communication link). The cardinality shows one Control system and one Weather information system serving multiple weather stations, and one Satellite per weather station.
