31
How Track Gates Work
When the Track Gates are Locked Down (No Longer Flashing). The system identifies SIX main features within the area inside of the Track Gates to distinguish this area as your target
32
Vehicle Mounted Charger (VMC)
The VMC is located in the Gunners Station and constantly monitors the vehicle’s voltage. The VMC operates with the supplied vehicle’s power in the range of 22.5 to 28 VDC and provides a converted conditioned output of 30.85-32 VDC with a nominal 31.85 VDC to the FCS and MTAS.
33
Commander’s Control Panel (CCP)
The CCP will only power up once the Gunner has gone through the proper Power-Up procedures for the GCP. When the CCP initially powers up, it will automatically run a Built-In-Test (BIT).
34
Commander's Video Display Terminal (VDT)
The VDT is an interactive touch screen display with 20 function key pad that allows users to perform maintenance and operational functions to ensure operational stability of the vehicle. It also allows use of the Embedded Training Module, display video from the Driver’s Vision Enhancer (DVE), and interact with FBCB2/BFT/JCR/JBCP computer.
35
Loader’s Control Panel (LCP)
The LCP permits the loader to move the ETS platform into the final position for missile loading or unloading and to inhibit the Gunners Handles during the loading process.
36
Card Rack Assembly (CRA)
The CRA is a central processor for the ATGM and its fire control components. It receives and distributes data between the VDT, CCP, LCP, GPA, FCS, TIA, and TAS. (MAIN)
37
Card Rack Assembly (CRA)
The Card Rack Assembly performs the following functions:  i. Monitors the health of the components in the PWS and communicates faults to the VDT/VDET.  ii. Routes RS-170 video to the VDT/VDET and Gunners Display.  iii. Induces Line of Fire inhibits based on the ATGM specific conditions.  iv. Induces Hatch Open inhibits if any of the hatch sensors detect an open hatch.  v. Induces Firing Obstacle Inhibit when the PWS has been moved into a fire inhibit zone of the chassis. vi. Implements automatic azimuth and elevation stops when the PWS is placed into Load.  vii. Fires smoke grenade launchers.  viii. Performs automatic deck clearance.
38
Power Electronics Unit (PEU)
The PEU It functions as a dual axis motor controller that controls the current and voltage going to the Azimuth Drive Assembly and either mast Elevating Drive Assembly or Elevation Angle Drive Assembly. The PEU directly provides DC-to-DC power amplification to the Azimuth Drive Assembly. The PEU provides DC-to-DC power amplification to the Power Transfer Assembly (PTA) in order to control EITHER the mast Elevating Drive Assembly OR Elevation Angle Drive Assembly depending on crew input. The PEU communicates motor speeds to Card Rack Assembly (CRA) to assist
39
Power Distribution Assembly (PDA)
The PDA provides electrical power distribution to the various assemblies of the ETS.
40
Power Transfer Assembly (PTA)
The function of the PTA is to transfer power from the PEU to either Mast Elevating Drive Assembly or Elevation Angle Drive Assembly depending on the position of the MAST switch on the GCP.
41
Azimuth Position Assembly (APA)
The APA is interfaced with mast azimuth ring. It is utilized to determine Elevated TOW System (ETS) direction relative to chassis.
42
Elevation Resolver
Mounted on the Elevated TOW System (ETS) platform right bearing housing. Measures the elevation angle of the target acquisition system and TOW missile launcher relative to the chassis.
43
Azimuth Drive Assembly (ADA)
The ADA is a 170 VDC motor that mounted on the hull and interfaces with azimuth gear ring in order to move the mast in azimuth. The Gunner’s Traverse Wheel is used to manually traverse the mast in azimuth.
44
ETS TOW Interface Assembly (TIA)
The TIA is an electronic interface assembly located on PWS platform that connects the MITAS and launcher with Gunner's Control Panel Assembly through the CRA. The TIA controls the wire cutter when the Gunner closes the Launching Equipment Switch.
45
ETS Elevation Angle Drive Assembly (EADA)
The EADA is located in the ETS platform. It functions as the drive motor that allows the Target Acquisition System (TAS) and Twin TOW Missile Launcher to move independently, in elevation, from the ETS Platform.
46
ETS Fire Control Sub-System (FCS)
The (FCS) is located in the ETS. It contains the electronic circuits necessary for tracking targets, missile guidance, Network Lethality and embedded training
47
ETS Fire Control Sub-System (FCS)
Contains the circuitry for tracking targets, missile tracking and guidance, embedded trainer and NET Lethality system.
48
Target Acquisition System (TAS)
**NVS (thermal)** Tracks missile’s shutterable thermal beacon Sensitive to delta-t’s as low as 1* F Enables use of ATT (track gates) Can track two targets **DVO (direct view optic)** Tracks the missile’s xenon beacon Does not have a digital zoom Cannot use ATT **ELRF** Beam at 3000m is approximately the size of a T-72, .8mil beam divergence. May return a reading of 0 at ranges under 300m
49
Precision Far Target Locator (PFTL)
The pFTL operates using inputs from three major  components. Integrated GPS Inertial Navigation System (INS) Laser Range Finder on the MITAS Provided for use in degraded operations using POSENT Provides following information: Target Location, Elevation, Zulu Time, Target Location Error Your location, Elevation, Zulu Time of laze.
50
Precision Far Target Locator (PFTL): Network Lethality
Operates using 3 major components 1) Integrated GPS 2) Inertial Navigation System 3) LRF on MITAS Used for degraded ops using POSENT -Target Loc -EL -Zulu Time -Targ Loc Error -Your Loc -EL -Zulu Time of Laz
51
Precision Far Target Locator (PFTL): FTL
The FTL function of the pFTL provides the AZ/EL and time of laze to TGT from TAS, the TAS location and the TGT Location
52
Upgraded Twin TOW Missile Launcher
The Upgraded Twin TOW Missile Launcher  is equipped with a launcher locking lip at the rear of the launcher.  There’s a manual locking lever and release mechanism located at the center rear of launcher.  It is used to secure or release missiles in launch tubes.  The launcher is also equipped with a manual missile arming and disarming mechanism located in rear of launcher. UACU or Upgraded Armament Control Unit. It houses the umbilical connectors, and the manual safe/arm selector. The ACU take the place of the bridge clamp from the ITAS. **Note: always check W225 after removing MILES
