SRP - Sensor Reporting Post
The Sensor Reporting Post (SRP) is an air/road transportable facility which operates in conjunction with the 407L Tactical Air Control System and may be set up in any worldwide environment. The SRP transmits and receives data from an Airborne Relay Platform (ARP). The data is stored, processed, and displayed for analysis by operators and then relayed to the TACS. The SRP facility is normally deployed in one standard configuration to include two radio relay facilities commonly called "orbits". The site equipment receives data from the ARP and relays this information to the AN/TSQ-91(V) assessment facility. The standard deployment configuration is depicted below:

Data Processing Module (OA 8450/TSQ-91(V)). Essentially the same as the CRC/CRP Data Processing Module, but includes expanded memory capacity and a line printer synchronizer which provides the interface between the HM 4118 computer and the line printer (GFE).
Air Conditioning Module (AN/TSA-35). Same as CRC/CRP.

Communications Relay Module (AN/TRC-164). The Comm Relay Module functions as the interface between the Radio Module and the Assessment Facility. This module processes all incoming data (down-link) into a format which can be used by the data processor and formats all commands from the operations central console (up-link) into a format which can be used by the ARP. A third function of the module is a self-test capability which allows for off-line checkout of the Comm Relay Module.

Radio Module (AN/TRC-165). The Radio Module recovers data from a down-link RF carrier signal, generates a modulated up-link signal, provides servo drive outputs to the antenna as a function of specific inputs, and provides support functions for checkout and tests.

TSQ-165 Modular TACC

TSQ-61 Shelter, Operations Center
The AN/TSQ-61 is an operations central which provides radar surveillance data by means of two AN/UPA-48 PPI (Plan Position Indicator) scopes and aircraft control (air/ground voice) communications through the AN/TSC-53 van for the Forward Air Control Post (FACP). The operations
central also coordinates the FACP operation by communicating with other elements of the Tactical Air Control System. SIF (Selective Identification Features) decoding is provided by KY-364 control boxes which are compatible with AN/TPX-48/TPS-44 and AN/TPX-47/TPS-43. Operations control consists of a group of components housed in a lightweight mobile shelter designed for transport by cargo truck, helicopter, cargo aircraft, transporter or rail. Air conditioning and heating is provided for creature comfort and equipment stability.
Capability: The AN/TSQ-61 contains two GRA-39 remote control heads which are interconnected with the
GRC-106/TSC-53 for UHF frequency agility. Similarly, the AN/TSQ-61 contains remote receiver control of the AN/TPS-44 for improving video reception on its two AN/UPA-48 PPIs. Patch panels for compatibility with the AN/TSC-53 and AN/TRC-97, as well as a manual plotting board, is also present in the AN/TSQ-61.

TSQ-91V - 407L Tactical Operations Center
The CRC/P Operations Center, when integrated with the AN/TPS-43 radar, functions as the major weapons control agency of the TACS by performing all functions of surveillance and weapons control in its assigned area of tactical responsibility. Modular in design, the CRC/P is capable of adjusting to the needs of a given deployment by additions/deletions to the basic set of the following modules: Group Display, Console, Data Processing, Ancillary Equipment, and Air Conditioning. The console and group display modules are joined together by means of an inflatable shelter to form a single operations room which houses operations personnel, manual display boards, consoles and communications equipment.
To this basic complex is added an ancillary equipment, data processing, and air conditioning module to form a minimum configured operation center. Additional console, group display and air conditioning modules are added to conform to the three basic deployment configurations; minimum, intermediate,
and maximum. The equipment for the CRP is identical to the CRC, only the manning would vary. The following depicts numbers of modules required in each configuration:

In each basic ops center, four consoles and technician stations are arranged on two raised daises, and a four-man table is positioned in front of the console rows. The two remaining consoles are located in the ancillary equipment module. Communications end instruments (TA- 720/741, or C-subset) are located at each console, tech table, plotter position, and computer operator station. Two modes of operation are possible; computer-assisted, in which the HM-4118 computer processes surveillance, computes weapons data and generates console displays; and manual, in which only raw radar data and SIF is displayed. In the computer-assisted mode, automatic SIF tracking and telling of tracks of interest via automatic data link (ADL) are available.
Capability:
1. The PPI or console display is a 16" CRT with a 4 1/4" square viewing surface auxiliary readout display. The console is 43" high, 33" wide and 36" deep and weighs approximately 290 lbs. The PPI can operate in both the manual and computer assisted mode. In the manual mode, the PPI can display:
Range marks and radar
SIF-alerts
Map videos
Radar returns

In addition, the range scale and off-set selection can be changed, active and passive SIF radar returns can be decoded; however, auto SIF tracking is not available, range and bearing cursor can be used, and radio/telephone communications remain in operation. In the computer-assisted mode, the computer sorts and distributes data, computes weapons guidance instructions, and alerts operators of critical situations. The console can be operated in seven operation modes plus Test and Manual; they are:
SSO - Search Scope Operator
ASO - Air Surveillance Operator
M&I - Movements and Identification Officer
SD - Senior Director
WAO - Weapons Assignment Officer
WD/ATC - Weapons Director/Air Traffic Controller
ADALO - Air Defense Artillery Liaison Officer

All nine modes are switch selectable at each console. Symbology and background information such as pairing indication, intercept point, offset point, geography, tactical air bases, flight corridors and FEBA can be displayed on the PPI. Several auxiliary readout displays (ARO) can be requested. Among them are:
Auxiliary data display
Track information display
Critical class display
Weapons track display
Controlled aircraft display
Alert displays.

2. Secondary Surveillance Radar Processor (SSRP). The SSRP basic task is to control the interrogations of the AN/TPX-47. The composite SIF video is received and processed with the following actions performed:
a. Serial to parallel extraction and single sweep defruiting for modes 1, 2, 3a, 4 and 5.
b. Inhibits code overlap (garble) info including "radio out".
c. Detects emergency replies and generates an alarm at PPI.
d. Determines proper mode of interrogation.
3. SIF Processor (STIP). The following lists the functions of the SIFP.
a. Target detection - automatic detection and measurement of A/C responding to SIF interrogations (excluding mode 4) and transfer data to computer.
b. Code validation - up to 3 modes per target.
c. SIF strobe elimination - inhibits false data transfer to computer under jamming or target saturated azimuth section conditions.

4. HM-4118 Computer. The computer is organized into functional modules; each module is frame-mounted and capable of communication with other modules. The Arithmetic Unit/Program Control Unit Processor Module, the
Memory Module and the Buffered Input/Output Module form the basic HM-4118.  The core storage capacity is 81,920 words with provision for growth up to 131,000 words. Also provisions are made for the addition of a second processor, and expansion of input/output capacity to 16 channels. Data can be input to the HM-4118 via the data entry keyboard and read in by the tape reader from perforated tape. Computer generated output data is available on punched tape, magnetic tape or transferred to the printer for hard copy. Outlined below is a general description of the operating characteristics:
a. Operation - parallel arithmetic
b. Logic - synchronous, 4 megacycle clock.
c. Word length - 18 bits.
d. Memory - one microsecond cycle time.
e. 18 bit words, 81,920 word storage capacity.
f. Input/Output - parallel 18 bit word data transfer, 8 bi-directional buffered channels, maximum single channel data transfer rate of 500,000 words per second, up to a maximum of 1,000,000 words per second when two or more channels are operative.
g. Number representation - sign and absolute magnitude.
h. Arithmetic organization - all arithmetic computations are performed in fixed point binary.
i. Double precision - provided for additions, divisions, square root, and multiplications.
j. Interrupts- 8 special interrupts in addition to one per I/O channel and real time clock interrupts.
k. Index Registers - 4 banks with 12 under registers each.

5. Computer Programs. The four basic computer programs are: Operational/
Recording (ORP), Simulation and Data Reduction (SDRP), Utility and Diagnostic Programs. The function of the CRP is to gather, process, and display data required to update the current air surveillance picture and to support the weapons assignment and control functions. In accomplishing this, the ORP also processes and records system exercise data; provides logic and timing control at computer interfaces with all consoles, radar and other peripheral devices. The SDRP prepares input tapes for the online program exercise function and reduces air situation data recorded online by the ORP. All computer programs are prepared and maintained by the Utility Program and the off-line Diagnostic Program provides the means for computer maintenance personnel to perform fault isolation.

TSQ-92 - Operations Central (TACC)
The TACC is the command action arm of the Tactical Air Control System.
Necessary facilities are provided to perform the Current Operations and
Current Plans functions of the Air Force Component Command Post (AFCCP).
Unlike the CRC/CRP, the TACC is essentially a manual operation; it
consists of desk positions, manually posted plotting displays and communications
equipment necessary to support personnel in the accomplishment
of the Tactical Air Control Mission.
Like the CRC/CRP the TACC is modular in design; capable of adjusting to
the needs of a given deployment by a building-block approach to the basic
set of the following modules: Group Display, Furnishings, and Air Conditioning.
The Group Display and Furnishings modules are joined together
by extending the external shelter side walls to serve as floor and attaching
the inflatable shelter. Essentially, the furnishings module is the
only unique module from the CRC/CRP in the sense that the A/C Module and
Group Display Module are interchangeable. The TACC is deployable in three
basic configuration; minimum, when Current Ops and Current Plans are housed under one shelter, medium,when Current Ops and Current
Plans divisions are collocated, but housed in separate shelters. The
following depicts the number of modules required in each configuration:

Capability: The TACC is designed with sufficient flexibility and modularity to operate in conjunction with the highest ground force field command responsible for planning and directing daily combat operations. Normally, this may be expected to range from division (and smaller size forces) up to a field army. The functions of the TACC at any of the force levels are essentially the same, however, the scope and volume of required activities vary to a considerable extent. In a situation where enemy air is a major concern or in which the military/political objectives are attainable through decisive or predominate air actions alone, the TACC functional requirements are much more extensive. Thus, the TACC deployment configuration must be compatible to plan and direct the entire spectrum of offensive and defensive air operations. This represents a necessary variable to associate the TACC position configuration to "force level" alone, i.e., minimum, medium, or maximum. The various TACC configurations can support, but are not limited to the following force levels:

Configuration
Air Force Level
Ground Force
Minimum    
1 Shelter*
3 TAC Ftr Sq 1 Division
  1 Comp Recce Flt  
  1 Air Refuel Flt  
Medium

  4 Tac Airlift Sq  
Maximum    
2 Shelters *** 24 Tac Ftr Sq 1 Field Army
  2 Comp Recce Sq  
  2 Air Refuel Sq  
  8 Tac Airlift Sq  

* Plans and Operations share the same facility.
** Plans and Operations functions each have a dedicated facility. Medium and maximum accommodations differ only in the use of furnishings and the number of manned positions.
***Plans and Operations functions each have a dedicated facility. Medium and maximum accommodations differ only in the use of furnishings and the number of manned positions.
Major Components: Group Display Module (AN/TSA-34). The Group Display Module is connected
(electronically, mechanically, and physically) to the Furnishings Module. It contains plotting boards, power distribution bay, commpatch bay, weather teletype, guard table, supply cabinet, safe, and rifle and clothing racks.

Furnishings Module (0A-8448/TSQ-92(V)). The Furnishings Module contains, as fixed equipment in the tactical mode, the fragmentary order teletype equipment and fixed air conditioning ducting. Power is distributed to the Furnishings Module by the power distribution panel of the Group Display Module. The outer foldout panel can be converted into a helilift pallet. The Furnishings Module functions as an area for preparation of fragmentary orders in the tactical mode. There are storage racks located on the walls for books and equipment.

Air Conditioning Module (AN/TSA-35). The A/C Module contains four, 5-ton environmental control units (GFE) and appropriate ducting.

TSQ-93 - Operations central (DASC)
The primary purpose of the DASC is to provide fast reaction to ground force requirements for immediate close air support, tactical reconnaissance and airlift needs. Working in close coordination with Army personnel, DASC personnel provide the focal point for information exchange, coordination, and allocation of sorties provided by the TACC to fulfill Army requirements. Like the TACC, the DASC is essentially a manual operation; it consists of desk positions, manually posted map displays and
communications equipment necessary to support personnel in their performance of the assigned mission.

Modular in design, the DASC is comprised of three unique modules; the Operations Module, Air Conditioning Module, and the Communications Center. The capacity of work is proportional to the deployment configurations, i.e., alternate, minimum, and medium. The following depicts the number
of modules required in each configuration:

Capability: The size of a DASC deployment is dependent primarily upon the force level supported. The highest ground force level conducting daily combat operations will be provided a DASC. Since this can vary from a single division (or smaller operation) to a field army, the size can vary considerably.
Usually the functions of the element do not change with a change in the force level supported. The various DASC configurations can support, but are not limited to the following force levels:
