its   interfaces   with   the    host    facility  and   other    interface   capabilities   is 
shown    in   Figure    1.      The    numbers  on   the  diagram   key   to  the    paragraph  numbers 
of  Section   3.1   which  describe   the    interfaces.      All   mechanical    and   electrical 
interfaces  between   the  G/AIT  and   the   host   shall   comply   with   the   FAA 
specification . 
3.1      Physical    interfaces 
3.1.1     G/AIT   equipment  rack  to  host   facility.      This   is   a  mechanical    interface 
which    provides    for    the   attachment  of  the  G/AIT  equipment,    exclusive   of   the 
G/AIT   antenna,   to    the   host. 
3-1.2     G/AIT   antenna   to   host   facility.      This   is   a  mechanical    interface   which 
provides    for  mounting   the   antenna.      The   location   shall   support   the   L   Band 
signal   reception   requirements   of   IGS-US-101. 
3.1.3     Host   facility  primary  power   and   ground   to  G/AIT.      This   is   an 
electrical    power   interface   which  provides   primary  power   of  the   required 
voltage,    amperage,   and    frequency  to   the  G/AIT  power   supply   unit  via   a   power 
cable.      The   G/AIT  power   requirements   shall   be   in  accordance   with   IGS-US-101. 
The  interface  connection  between  the  G/AIT  ground  and   the   facility  ground   is

categories : 
a.  Computer   to   computer   interface   processing

interaction  of  the  G/AIT  processor   with   the   user/host   processor.     The   user/ 
host   system   has  been  defined   as  the   Automatic   Data   Processing   (AD?)   system 
that  operates  onboard    some  airborne   command   posts  (i.e.,    E-43   and   EC-135C).

it    provides   adaptability   to    a  variety  of   HOLK- provided   off-the-shelf 
communication    interface   devices   combined    with  related   ROLM   software. 
In    this  configuration,   the   G/AIT  is  directly  connected    to   AD?.      All   queries 
originated    from   any  one  of  the    PD-3000   Display   terminals   will   be  directed    to 
the    ADP  and    will    be   sent   to    the   G/AIT   from   ADP.      Responses   to    the    query 
and/or   data    are    sent  back    from   the  G/AIT  to   ADP  through   the    same  direct 
interface.      It    is   the    AD?  task  to  direct   these   responses/data    to   PD-3000s   or 
the    high   speed    printer   as  appropriate. 
As   shown   in    Figure   2,    solid    lines  represent  operational   data    paths   and    the 
broken   lines    shdV  the'  nonoperational   data    paths. 
Three    switches   are   shown    for   ease  of  understanding    and   not  to   levy  a 
requirement    for   three    independent   switches. 
3-2.8.2     G/AIT   to  CCPDS   interface.      This   function   is   performed   by  direct 
interaction  of  G/AIT  processor   with   the   user/host   processor.      This   is  the 
Command   Control    Processing   and   Display  System   (CCPDS),  a  ground   based    system 
used    at    four  major   command   posts  (NMCC,     ANMCC,    SAC  and   NORAD)  . 
As   shown   in   Figure  3,    CCPDS  receives  data   simultaneously  from   two  G/AITs . 
Data    from  one  G/AIT  is   used,    and   the  other  data  is  rejected.      The  decision  on 
what   data   to   use   is  made   within   CCPDS.  ..

Devices    serve:    t.-.-c  ush    CZ?DS    (i.e..    Display,    TTY  and    high-speed    p-in-^er)    have 
no   direct    interface    path    tc    the   3/A.IT,    all    data    t-ansr.i tted   or    received   by 
these   devices   destined    to    —  or    initiated    at   G/AIT,    pass   through   CCPDS. 
CCPDS  uses    Honeywell   6080   processors   and   offers   high-speed,    full   duplex 
computer    to   computer    interface   using    ADCCP  protocol    and    P.5-232   compatible 
electrical    interface. 
Tne   G/AIT   shall    provide   the   compatible    hardware   and    the    software    to   enable 
communication   with   the   CCPDS.      The  G/AIT  display  console   can  be   used    as  a 
backup   device. 
3-2.9     Display  processing.      The   display  processing    function   is  performed    in 
the  G/AIT   for    provision   of   IGS   NUDE 7  data,    IGS   Orbital    Subsystem    status   and 
G/AIT  configuration   and    operation    status   data    to   the   user.     The   display 
processing   can  be    initiated    internally  by  the  G/AIT  for  displaying   alarms  and 
error   conditions,   or   by  the   action   officer    in    query  form.      A  query  can   be 
sent   to   the  G/AIT   from   either   a  display  console  directly  connected   to  G/AIT 
(stand   alone  G/AIT),  or    from   any  one  of  the  display  devices  connected   to  an 
intermediary  medium   such  as   ADP  or   CCPDS. 
In   an   airborne   environment   with   ADP,    as  depicted    in   Figure  4,    if   ADP  becomes 
non-operational  (due   to   a  malfunction  or   service/maintenance),   the   action 
officer   is  able  to   switch  any  one  of  the   ADP's  PD-3000   Display  terminals  to 
the  G/AIT.      This  is  done   through  the   use  of  switch  no.    1    (SW1).      The  G/AIT 
will   have  the  capability  to   identify  the   type  of  interconnection   established. 
It  will    format  the  data  before  output   to  the  display  device  to  which  it  is

(A3?  operational)  G/AIT  will   output    jr. forma tteri    cata    wir.h   the   assumption    that 
the    formatting   will    be   performed    outside  of  the   G/AIT    (i.e.,    AD?)    before 
display. 
In    the    CCPDS  ground    environment   it   is   assumed    that  the    system   is  operational 
at   all    times  and    there   is  no  direct  connection  of  CCPDS' s    Display  terminai(s) 
with   G/AIT. 
3.2.10     Hard   copy  processing.      Tne    hard   copy  processing    function   is   performed 
in   the  G/AIT  for    provision  of  data   specified    in   3-2.9      in   hardcopy/ printed 
form.      The   hardcopy  device,  due   to   its  mechanical   design,  does  not  offer  many 
of  the    formatting    flexibilities  offered   by  the  display/graphical    terminals; 
hence,  data   routed    to    this  device    for   printing    is  limited    to   data   in   textual 
format   and   not   in  graphical    format. 
As  depicted    in   Figure  5,    hardcopy  processing    is  activated    only  when   ADP  and 
display  terminals  or   the  corresponding   ports  on  the  G/AIT  become  non- 
operational.      In   this  mode,  only  one  of  the   UGC-129  teleprinters  can  be 
switched   to  the  G/AIT  and   initiate  queries.      This  is  done  through  the  use  of 
switch  no.   2   (SW2). 
On   receipt  of  a  query,   the  G/AIT  will   respond  by  sending  data  directly  to   the 
teleprinter  it  is  connected   to,  or  the  high  speed   printer,  depending  on  the 
routing   parameter   used .

3-c. '1      r.±z>h   speed   output    processing.      Output    processing    is   a    function 
performed    in   G/AIT   for    provision  of  data   originating    :>om   t-he  G-'AIT  through   a 
one-way   interface.      5ecause   of  the   high  speed    nature   of  this   interface, 
massive   amounts  of  data  can  be  output   in   hardcopy   format   to   the   user/action 
officers   in   control   of  the   G/AIT  in   a  relatively  short   time.      Trie   user/action 
officer   can   use    this   function  by  sending  a   query   to   the  G/AIT  via   the  G/AIT- 
external    terminal    device.      The   request    will    cause   this   function   to  be 
activated    and,    in   turn,   data    to  be   routed   and    transmitted    through   the   high 
speed    interface   to    the   device   where    it   can   be   available   to   the   requestor   in 
hardcopy   form. 
In   an   airborne   environment  with   ADP ,    this    function   is    always   performed   in  ADP. 
(The   switch    for  high    speed   printer    is    set    to  ADP.)      In    the  event   the  ADP   is   not 
operational    (Figure   S),    the   high   speed   printer   is    switched  back    to  G/AIT  switch 
no.    3    (SW3)    allowing   a   PD-3000  Display    terminal    to      direct      data      tc 
the   high      speed    printer   through      the   G/AIT.      The      data      can     be      in 
plain    text,    formatted   text,    or  plotted    form.      The   high    speed   printer  onboard 
the   E-4B    is    model   number  HSP   3609-212A,    manufactured  by  MILTOPE  Graphic,    Inc.
