Launch Vehicles and Remote Sensing Flashcards
What is the primary purpose of a Launch Vehicle?
To put the satellite into its desired orbit
Remote sensing is defined as:
The science and art of identifying, observing, and measuring an object without coming into direct contact with it
Which type of Remote Sensing provides its own source of energy?
Active remote sensing
Synthetic Aperture Radar (SAR) is active or passive remote sensing?
Active
Passive remote sensing:
Records/measures energy that is externally available
What are the benefits of active remote sensing?
It can be used to examine wavelengths not sufficiently provided by the sun
Are electro-optical sensors, passive or active remote sensing?
Passive
what type of sensors captures, observes, and records visual electromagnetic light?
Electro-optical
What type of remote sensing uses microwave technology?
Radar
In Remote sensing classifications, SWIR & MWIR are associated with:
Infrared sensors
Which Remote Sensing system uses both PIR and radar technology?
Active Infrared (AIR)
SATCOM (Radio waves) uses:
Both active and passive remote sensing
In PNT systems, which component is considered Passive remote sensing?
The ground receivers
The space segment (satallite) in PNT systems is:
Not considered remote sensing
PIR (passive infrared) sensors in Remote sensing:
capure, observe, and record IR reeflected and emmitted by objects
Which sensor type combines multiple technologies to detect movement?
Active Infrared (AIR)
Remote sensing classifications include:
Both ground-based and space-based sensors
SATCOM systems primarily work with:
radio waves
The main advantage of Passive Remote Sensing is:
It detects external stimuli and records reflected/emitted energy
For remotesensing systems, AIR sensors combine:
Combine PIR and radar technologies
