SECTION II. INTRODUCTION
Motivation Use the following points to motivate the students:
· During Operation Desert Storm, many crews became disoriented in the vast desert, especially during hours of limited visibility. To overcome this problem the BFV-ODS has a built-in navigation system.
· The Digital Compass System (DCS) provides the Bradley with on-board navigational data for the driver and commander.
· The correct use of the DCS will allow you to arrive at the site of the battle at the planned time.
· Knowing the components, navigation configurations of the DCS, and their functions will enable the students to use the capabilities of the DCS.
· The students have already been introduced to some of the BFV-ODS improvements; during this lesson they will learn to operate the DCS.

Bradley SHOW VGT DCS-2, Digital Compass System - BFV-ODS Navigation System.
Navigation
System THE BFV-ODS NAVIGATION SYSTEM PROVIDES NAVIGATION INFORMATION TO
THE VEHICLE BY INTEGRATING THE DCS AND THE PLGR. THE DCS USES
LOCATION DATA FROM THE PLGR TO DEVELOP PRECISE NAVIGATIONAL DATA.
THE DCS INTEGRATES VEHICLE HEADING INFORMATION WITH PLGR POSITION INFORMATION AND DISPLAYS VEHICLE PATH INFORMATION ON THE DRIVER’S AND COMMANDER’S DISPLAY UNITS.
THE DCS PROVIDES A NAVIGATION CAPABILITY EVEN IN THE ABSENCE OF PLGR.
THE DCS’s MAGNETIC HEADING CAPABILITY ASSISTS THE VEHICLE COMMANDER OR GUNNER TO DETERMINE FIRE DIRECTION DATA FOR COMBAT IDENTIFICATION, TARGET HAND-OFF, AND INTRA-VEHICLE FIRE COORDINATION.
THE DCS ALSO FEATURES DECLINATION OFFSET SETTINGS WHICH ALLOW NAVIGATION BY TRUE, GRID, OR MAGNETIC NORTH BEARINGS.

Reacquisition
IN TARGET REACQUISITION, THE TARGET’S POSITION AND RANGE ARE CALCULATED WITHOUT REACTIVATING THE BELRF. THIS ALLOWS REPOSITIONING THE VEHICLE TO ENGAGE THE TARGET FROM A BETTER LOCATION. TO REACQUIRE THE TARGET, FOLLOW THESE STEPS:
· STEP 1 - OPERATE THE TURRET IN THE POWER MODE AND THE NAVIGATION
SYSTEM IN THE TURRET MODE.
· STEP 2 - OPERATE THE BELRF, LASING THE TARGET FOR THREE SECONDS.
· STEP 3 - WHEN TARGET IS DISPLAYED ON COMMANDER’S DISPLAY, THE
DRIVER DRIVES TO THE DESIRED LOCATION.

· STEP 4 - THE COMMANDER’S DISPLAY WILL SHOW SLEW WITH CHEVRONS
INDICATING THE DIRECTION TO SLEW THE TURRET.
· STEP 5 - WITHIN TWO DEGREES OF THE TARGET THE CHEVRONS WILL BE
REPLACED WITH THE WORD TARGET.
· STEP 6 - ACQUIRE THE TARGET IN THE INTEGRATED SIGHT UNIT.

Operate in the SHOW VGT DCS-48, Digital Compass System - Operate Navigation System -Dead Reckoning
Dad Reckoning Mode.
(D/R) Mode
THE NAVIGATION SYSTEM ENTERS THE DEAD RECKONING MODE AUTOMATICALLY WHEN THE PLGR SIGNAL IS LOST OR WHEN THE PLGR IS NOT TRACKING SATELLITES.
IN DEAD RECKONING, THE DCS TAKES THE BRADLEY’S LAST KNOWN POSITION AND THE WAYPOINT LOCATION AND GIVES DIRECTION AND DISTANCE TO THE WAYPOINT
IF THE PLGR IS NOT BACK ON LINE AT THE WAYPOINT, THE DECLINATION MUST BE RE-ENTERED AND THE COMPASS MODE USED TO CONTINUE TO THE NEXT WAYPOINT.

THIS PORTION OF THIS LESSON WILL ACQUAINT YOU WITH TROUBLESHOOTING TECHNIQUES AVAILABLE TO RESOLVE MALFUNCTIONS. WHEN THERE IS NO POWER TO EITHER OF THE COMPASS DISPLAYS, TAKE THESE STEPS:
· STEP 1 - CHECK THE DRIVER’S CONTROL BOX CIRCUIT BREAKER. IF THE
WHITE BAND SHOWS, PUSH THE CIRCUIT BREAKER TO RESET IT.
· STEP 2 - CHECK THE RYJ BOX TO ENSURE THE DCS SWITCH IS IN THE UP
POSITION. IF IT IS DOWN, RESET THE SWITCH TO THE UP POSITION.
