17. Employment of Inertially-Aided Munitions

Question 1

IAM Advantages

Answer 1

Weapons Accuracy
Standoff ranges
All weather capable
Multiple target capability 
Modifiable impact angle

Question 2

IAM limitations

Answer 2

Moving targets- Single mode have no caps against moving targets/ dual mode IAMs allow follow on guidance via laser designator

Location error- require extremely accurate tgt location

Malfunctions- Loss of guidance, control fin hard-over(PGM should always be employed parallel to friendlies!

Time requirement- time required to coordinate must out-weigh time required to provide immediate weapons effects

Question 3

What type of control should GPS/INS fall under?

Answer 3

Type 2 or type 3

Question 4

Weapon/tgt errors

Answer 4

CEP
Circular Error Probable

Either weapons guidance for PGM, aircraft platform for GP, and delivery system for IDF

Question 5

TLE

Types of TLE?

Answer 5

Target location error- difference between the coordinates generated and the actual location of tgt

Circular error) CE- Horizontal ground plane
Vertical error) VE- vertical plane
Spherical error) SE- Three dimensional spherical space (VE and CE combined)
Height above ellipsoid) HAE- MSL or HAE
JDAMs work in HAE,

Question 6

TLE Categories?

Answer 6

CAT I - CAT VI

Question 7

CAT I grids are how accurate ?

Answer 7

CE of 0-20ft / 0-6meters

Question 8

When BOC MOA is employed the weapon will use only what?

Answer 8

Will only use the coordinates and elevation that are entered to determine the point of impact.
