SPECTRUM MANAGEMENT BLOCK 5
TEST GUIDE UPDATED ACTUAL Exam
Questions and CORRECT Answers
The Global Positioning System consists of how many satellites and is accurate to how many
meters? - CORRECT ANSWER 24 satellites, 3 spares, 2 meters
What are the Characteristics of an Elliptical, Circular, Equatorial, and Polar Orbit? - CORRECT
ANSWER Different velocity at every point of its orbit.
What is a Satellite Footprint? - CORRECT ANSWER The area of the earth covered by a
satellite's downlink.
What is the difference between synchronous and non-synchronous satellite orbits. - CORRECT
ANSWER Synchronous : if viewed from the surface of the Earth, the satellite would
always be the same height in the sky.
Nonsynchronous :appears to move from horizon to horizon. To an observer on the surface of the
Earth, the satellite would "rise" from one horizon, travel across the sky, then "set" on the
opposite horizon.
An atmospheric condition caused by ionospheric irregularities due to cooling is the definition of?
What frequency range is most affected? - CORRECT ANSWER Scintillation UHF M225-
M399.975
What is the lead time for GMF SARS? - CORRECT ANSWER USA 45 days, Germany 10
days, Southwest Asia 120 days, Japan 120 days, Europe 90 days, Korea 60 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, or PRR, or PRF.
What is a klystron/Magnetron? - CORRECT ANSWER A high powered amplification
tube used to a specific frequency.
A high powered amplification tube that is controlled by a magnetic field and tunable.
The satellite pointing guide will provide the operator with what information? - CORRECT
ANSWER Azimuth and Elevation
What is the TACAN used to measure? - CORRECT ANSWER Azimuth and distance
information.
What is paragraph 1 of a UHF TACSAT SAR? - CORRECT ANSWER Purpose
TROJAN SPIRIT II is a civilian satellite lease program utilized by which branches of the United
States Armed Forces? - CORRECT ANSWER Army and Marine Corps.
What is the replacement of TCAS II and ETCAS that detects nearby aircraft? - CORRECT
ANSWER MILACAS
What are the spread spectrum techniques? - CORRECT ANSWER Freq Hopping, Time
Hopping, Pulsed FM, Hybrid Systems, direct sequence.
What is pulse duration? - CORRECT ANSWER Pulse duration or pulse width is the length
of a pulse emitted over 50%.
Radar range is measured in what? - CORRECT ANSWER Nautical Miles.
