MARTIN MARIETTA CORPORATION
SAT .RS OP..DER NO.
In 1982 Kinemetrics/TrueTime redesigned the Models A-468MS/RK and
A-468RK GOES antenna system. The newer MK II version of the
Model A-468MS/RK has a different circuit card and has different
dimensions than the MK I. The MK II antenna is still compatible
with the MK I Remote Kit, and the MK II Remote Kit is still com-
patible with the MK I antenna as far as function is concerned.
The MK II version of the Remote Kit also has a different circuit
card and different dimensions.
When we supplied GOES antennas to Martin Marietta in 1984, we
were able to remanufacture MK I kits from resources that were
still available to us. Those resources are no longer available.
Producing MK I antennas at this point in time would entail an ex-
tremely prohibitive expense for Martin Marietta. The MK II GOES
antenna system is now the only version available to us. However,
we can still accommodate Martin Marietta van application by
providing a special adapter plate to be installed on the MK II
Remote Kit. This plate will allow the user to interchange both
MK I and MK II Remote Kits. Both units
as far as input/outputs are concerned.
are
The mounting holes in the antenna pedestal baseplate have been
drilled out to 0. 459", and the upright mounting stanchion has
been shorted to 9.5" to conform to Martin Marietta Drawing No.
