In this configuration, the G/AIT is directly connected to ADP. Ail queries originated fran 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 througn the same direct interface. It is the ADP task to direct these responses/data to PD-3009s or the high speed printer és appropriate. As snown in Figure 2, solid lines represent operational data paths and the broken lines shdw 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. nis function is performed by direct interaction of G/AIT prosessor 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. .. . ~12-

CCPDE uses Honeywell 6080 processors and offers high-speed, full duplex computer to computer interface using ADCCP protocol and RS-232 compatible electrical interface. Tne G/AIT snsll provide tne competible 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 NUDET deta, 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 (swt). The G/AIT will have the capability to identify the type of interconnection established. It will format the data befcre output to the display device to which it is

For display devices not directly connectes to tne S/AIT, e (ADP operational) G/Sit will output unformatted ceta with the essimrtion that che 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 end there is no direct connection of CCPDS's Displey terminal(s) with G/AIT. 3.2.10 Hard copy processing. Tne hard copy processing function is per formed 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, cata 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. -17-

Gitput processing is 2a function perforned in G/SIT for provision of data origineting from the S/AlIT tnrough a one-way interface. Because of the high speed nature of this interface, massive amcunts of deta can be output in hardcopy format to the user/action officers in control of the G/AIT in a relatively short time. THe vuser/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 transzitted throusn the high speed interface to the device where it can be aveilable to the recuestor in hardcopy form. In an airborne environment with ADP, this function is always performed in ADP. (The switch for nigh speed printer is set to ADP.) In the event the ADP is not operational (Fifure 4), the high speed printer is switched back to G/AIT switch no. 3 (SW3) allowing a PD-3000 Display terminal to direct date te 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. 3.3.
