Axial jet, radial jet, velocity jets, antenna, spin axis.
Spin-stabilized satellite controls. omnidirectional antennas around spin axis.
despun inner platform mount controllable antennas. Both have radial jets inner radial
jets so inner opposite of outer. communications antenna points to earth. Phase II DSCS use despun
platform with four high gain antennas. steerable narrow beam antennas. high density traffic.
horn antennas. remote minimize RF interference. remote interconnect by links using telephone
cables or microwave radio. highly sensitive receiver, powerful transmitter, multiplex,
modulating-demodulating modem demodem and telemetry equipment.
Earth terminal antennas highly directional, high gain, transmit and receive simultaneously.
Large high gain parabolic antennas. AN/FSC-9 parabolic 60 feet in diameter. AN/MSC-46 parabolic 40
feet diameter, AN/TSC-54 uses cluster of four parabolic antennas each 10 feet diameter.
equvalent to parabolic antenna 18 feet diameter.
