Topic 1: Electromagnetic Waves
Electromagnetic waves differ from mechanical waves in that
they do not require a medium to propagate. This means that
electromagnetic waves can travel not only through air and solid
materials, but also through the vacuum of space.
According to your Knowledge, answer the following
questions:
- Describe the characteristic of Electromagnetic Waves?
- Radio Waves travel along different paths:
a. State their names?
b. Which of them does Loran-C receiver receive?
Topic 2: Loran-C and e-Loran Systems
Two navigation systems that produce position through the
measurement of the difference in times of radio signals from two or
more synchronized transmitters at fixed points. Such systems
require the use of a receiver, which measures the time
difference.
According to your Knowledge, answer the following questions:
