RADIO COMPASS OPERATION.

TM 32-5895-206-10

NOTE

The second bearing may be taken by moving

the set to a second location or by using a

second unit with similar capabilities at the

second site. If the set is moved, follow the

instructions for movement indicated below.

Select the second site by the guide in

paragraph 2-4.

e. Plot location of target transmitter on an area map or

chart by triangulation method which follows. Plot location of each

receiving site on map. Note direction of magnetic north from

each site. Draw a straight line through each site at bearing angle

taken at that site. Lines will cross at target transmitter location.

Figure 2-13 shows a typical triangulation plot.

f. Plot accuracy is affected by bearing accuracy, distance

to target transmitter, and difference between bearing angles.

Best accuracy is obtained with ideal terrain and site conditions, at

close range to target transmitter, and with large differences

between bearings.
