2026-2027 Updated.
True or False, crews of more automated aircraft experience higher level of workload and
uncertainty. - Answer True
_______ sensing is the process of measuring an object or phenomenon of interest from
distance. - Answer Remote
_______ and _______ are the two general categories of sensors that are used by UAS. - Answer
Active and Passive
The radiation source detected in the short wave infrared (SWIR) and near infrared (NIR) is the
_______. - Answer Sun
This payload technology uses a laser beam and a receiver to measure the distance to the
ground. - Answer LiDAR
This payload systems maps by using a band of the EM spectrum in the range of 1 m-1 mm. They
send out a radar pulse and use the reflected radar signal and the receiver's motion to construct
a 2-D or 3-D image of the returning echoes. - Answer SAR
What payload technology enables intelligence, surveillance, and reconnaissance? - Answer
Gimbaled payload
A photogrammetric point cloud's greatest power lies in the ability to.... - Answer Work in the
three dimensions
A Normalized Difference Vegatative Index is created by manipulating the _______ band and the
NIR bands. - Answer Red
An egocentric control station refers to an operational perspective where the pilot feels as
though they are.... - Answer withing the aircraft looking outside
For UAS that o not use physical controls the primary means of controlling the aircraft was the
use of a computer screen that displayed a virtual control/display combination that could be
manipulated through the use of a computer pointing device such as a.... - Answer Trackball
, A commonly used classification for data link is line-of-sight (LOS) an beyond-line of-sight (BLOS).
In LOS systems, the UAS is always in line of sight with the GCS. In BLOS systems, .... - Answer
line of sight is maintained by using other links
How is wireless communication even possible in free space, given that it excludes the possibility
of a guiding system such as a two-wire line or a coaxial line? - Answer Radiation
_______ waves are caused when a signal bounces off objects before reaching the receiver. -
Answer Reflection
Multipath signals can lead to both ______ and _______ interferences with the direct signal. -
Answer Destructive and Constructive
Modulation combines _______ with a carrier signal. - Answer Information.
The _______ takes in the modulated signal and outputs an amplified radio frequency (RF) signal
transmission. - Answer Transmitter
The frequency hopping technique is what is known as a _______ technique because it changes
frequency of transmission in a pseudorandom fashion as if to spread the energy over a larger
bandwidth. - Answer Spread spectrum
A _______ is a hypothetical antenna that radiates equally in all direction. - Answer Isotropic
radiator
The antenna _______ is simply, the product of the directivity with efficiency, which accounts for
cable, connector losses, and dielectric losses. - Answer Gain
All electromagnetic (EM) waves possess an electric field and a magnetic field direction. The
electric field direction is considered _______. - Answer linear polarization
Data link signals are amplified in a low-noise amplifier (LNA) very close to the antenna. In order
for the signal to be picked up and demodulated by the receiver a certain _______ called the
receiver sensitivity is required. - Answer Signal-to-noise ratio
Sources of noise in the wireless communication system include all of the following except... -
Answer blackbody radiation
