PALADIN PLATOON COMMUNICATIONS SEQUENCING

The following is an example of communications sequencing used for managing the platoon Fire Direction digital net.

 

HOWITZER LOGICAL NUMBER

4/2

 

3/2

2/2

 

1/2

 

NET ACCESS DELAY (in seconds)

2.5

 

2.0

1.5

 

1.0

 

 

 

 

 

 

Platoon

BCS

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

.5 sec

DELAY

 

 

HOWITZER BROADCAST ADDRESS

(Used for communications between

BCS and the howitzer[s].)

 

 

 

 

 

 

 

 

HOWITZER PHYSICAL ADDRESS

(Used for communications between

howitzer and target acquisition

agency during linked operations.)

 

 

 

 

 

 

 

 

NOTE: In this example, the BCS has a lesser net access delay and, therefore, the highest priority on the net.

A portion of any digital transmission is the hold timer factor, which is transparent to the operator. This specifies the amount of time the other subscribers on the net must wait before trying to access the net after a transmission between the BCS and the AFCS. This is a software setting, is based on operator entry as follows:

 

BIT RATE

BLOCK MODE

 

HOLD TIME FACTOR

 

1200

 

Single

 

0.16

 

1200

 

Double

 

0.32

 

0600

 

Single

 

0.32

 

0600

 

Double

 

0.64

 

Once the hold time expires or is canceled, the net access delay timer is activated. Therefore, an automatic transmission or retransmission would not occur until the net access delay time expires.

TRANSMISSION SEQUENCE

 

NOTE: Should the BCS need to transmit, it may "jump ahead" of a howitzer. In this instance, a howitzer would reset his transmission sequence as show above.
