I want to know the answer to the following question:
What is the purpose of the BeiDou-1 system using stallites in geostationary orbit?
All the background I'm provided with is that "Unlike the American GPS, Russian GLONASS, and European Galileo systems, which use medium Earth orbit satellites, BeiDou-1 uses satellites in geostationary orbit.". Is that enough to answer the question?
Answer: no
