MILA contained thirteen antennas and equipment to provide communications between a space vehicle (like the Shuttle Orbiter) and its control center Johnson Space Center in Houston, Texas for the Shuttle during its mission. Antennas at MILA tracked or point directly at the radio frequency signals transmitted from a moving space vehicle. A ranging signal transmitted from MILA to the space vehicle and back again establishes the distance between MILA and the vehicle by how long the two way trip takes.
MILA's antennas included two 30ft (9.1m) S-Band antennas (used to track
spacecraft), one space-pointed Ku-Band 10ft (3m) parabolic dish
antennas (used to relay signals to and from TDRS), one ground-based 10ft
(3m) Ku-Band antenna (used to relay signals from MILA to Orbiter
locations at KSC), two UHF antennas (used for voice communications), one
4ft (1.2m) X-Band dish, one 4ft (1.2m) S-Band dish, one 15ft (4.6m)
S-Band dish (used as a backup for the 9.1m dish), two 4ft (1.2m)
calibration dishes on the facilities north tower, one 6ft (1.8m)
microwave antenna on the north tower (used as a link to the PDL tracking
station, one shortwave antenna (used to receive timing signals from
NIST and two UHF antennas for monitoring the UHF tracking antennas.
