Methods and apparatuses for communicating in a satellite communication framework with spatial diversity are described. In one embodiment, a method for controlling communication in a satellite communication network having multiple constellations and a satellite terminal with a single electronically steered flat-panel antenna capable of generating a plurality of beams for communication links with multiple satellites, comprises: determining, under network control, availability of a plurality of networks by which network traffic may be exchanged with the single electronically steered flat-panel antenna; and managing, under network control, two or more satellite links between the single electronically steered flat-panel antenna and two or more satellites of different networks to route the network traffic, including determining when to use each of the two or more satellite links, the two or more satellite links being generated using two or more beams from the single electronically steered flat-panel antenna.
