LESSON 2
LINE-OF-SIGHT ENGINEERING
Critical Tasks: 01-7110.07-0002
01-7113.07-0011
OVERVIEW
LESSON DESCRIPTION:
In this lesson, you will learn about the planning considerations for line-of-sight (LOS)
engineering, to include determining antenna heights for transmit/receive sites and developing a
manual LOS profile.
TERMINAL LEARNING OBJECTIVE:
ACTION:
Describe the planning considerations in LOS engineering.
CONDITIONS:
You will have this lesson.
STANDARDS:
To demonstrate competency, you must achieve a minimum of 70% on the
subcourse examination.
REFERENCES: The material in this lesson was derived from the following publications: TC
24-21 and TC 24-24.
INTRODUCTION
Command and control is exercised at every level of operations. There must be an integrated
theater area communications system which spans battlefield echelons, from division and corps
through echelons above corps (EAC). The communications systems must have the flexibility,
dispersability, mobility, and transportability required to meet the demands of commanders.
Bringing Mobile Subscriber Equipment (MSE) capabilities into EAC satisfies user mobility
requirements and eliminates artificial communications boundaries between corps and EAC. Tri-
service tactical communications (TRITAC) at EAC, and MSE at corps and division, form a
theater-wide signal network that supports all commanders. You must be able to determine
whether a LOS path exists between the transmit and receive sites for the TRITAC and MSE
radio systems.
