[单项选择]

The new global satellite communications systems will offer three kinds of service, which may overlap in many different kinds of receivers.
VOICE. Satellite telephones will be able to make calls from anywhere on the earth to anywhere else. That could make them especially useful to remote, third world villages (some of which already use stationary satellite telephones), explorers and disaster-relief teams. Today’s mobile telephones depend on earth-bound transmitters, whose technical standards vary from country to country. So business travelers cannot use their mobile phones on international trips Satellite telephones would make that possible.
MESSAGING. Satellite massagers have the same global coverage as satellite telephones, but carry text alone, which could be useful for those with laptop computers. Equipped with a small screen like today’s papers, satellite messages will also receive short messages.
TRACKING. Voice and messaging systems will
A. business travelers use mobile phones on international trips
B. possible calls from anywhere on earth to anywhere else
C. explorers happy
D. all above
