Spectrum Management: Block 5 UPDATED
ACTUAL Exam Questions and CORRECT
Answers
The global positioning system consists of how many satellites and accurate to how many meters
- CORRECT ANSWER 24 + 3 spares, accurate within 2 meters
What are the characteristics of an elliptical, circular, equatorial, and polar orbit - CORRECT
ANSWER 1. Elliptical: Oval in shape and the Earth is not in the center of the orbit. This
type of orbit is nonsynchronous and the speed that the satellite is traveling is not constant.
2. Circular: One in which the Earth is at the center of the orbit and the satellite is always at the
same velocity and distance from the Earth
3. Equatorial: Orbits the Earth directly above the equator.
4. Polar Orbit: Orbits about the Earth within a plane perpendicular to the Earth's equatorial plane.
Only a polar orbiting satellite will pass over the Earth's North and South poles
What is a satellite footprint - CORRECT ANSWER The Earth area covered by a satellites
downlink
What is the difference between synchronous and non-synchronous satellite orbits - CORRECT
ANSWER 1. Synchronous: Satellite's orbit has a velocity and altitude that prevents it from
appearing to move east to west or west to east; in respect to the surface of the Earth, it remains
stationary.
2. Non-Synchronous: Satellite does not remain stationary, but appears to move from horizon to
horizon.
An atmospheric condition caused by ionospheric irregularities due to cooling is the definition of?
What frequency range is affected? - CORRECT ANSWER SCINTILLATION, UHF
TACSAT bands 225-400MHz
What is the lead time for GMF SARS? - CORRECT ANSWER 1. USA: 45 days
, 2. Germany: 10 days
3. Europe: 90 days
4. Southwest Asia: 120 days
5. Korea: 60 days
6. Japan: 120 days
What is the system that is used to identify an aircraft through transponder returns - CORRECT
ANSWER IFF/SIF
What does the acronym SAR stand for - CORRECT ANSWER Satellite access request
In reference to RADAR, the number of pulses emitted per second is referred to as what? -
CORRECT ANSWER PULSE REPETITION RATE (PRR)
What is a klystron/ magnetron - CORRECT ANSWER 1. klystron: is a high-powered
amplification tube tuned to a specific frequency.
2. magnetron: is a high-powered amplification tube in which the flow of electrons is controlled
by an externally applied magnetic field.
The satellite pointing guide will provide the operator find what information - CORRECT
ANSWER 1. Elevation
2. Azimuth of the satellite
3. Satellite orbits
4. RSSC phone numbers
What is the TACAN used to measure? - CORRECT ANSWER Azimuth + distance Info
What is paragraph 1 of the UHF TACSAT SAR? - CORRECT ANSWER Purpose
