AVIA 230 Quiz: Systems and Sensing

Covers the Learn material from Module 2: Week 2.

1. The phrase ___ _______ comes from the Latin for “in place.”
2. The most important element of the UAS is the __________ element.
3. These sensors generate an image using thermal radiation emitted from every object.
4. Autopilot equipment is designed to:
5. Beyond line-of-sight (BLOS) operations refer to operating the UAS via _________ communications or using a relay vehicle, usually another aircraft.
6. sensors are those that emit some form of electromagnetic (EM) radiation that is directed at a target and then measures the reflected signal.
7. ________ can also be improved utilizing a directional tracking antenna.
8. One of the largest stumbling blocks in UAS work in agriculture is dealing with the ______ ______ after the mission is over.
9. refers to that distance beyond which the naked eye cannot detect an aircraft, which is a much shorter distance than radio frequency BLOS.
10. can be used to create highly detailed 3D point clouds that can be used to recreate an object in three dimensions.
11. What is orthorectication?
12. When working with radio frequency, LOS and BVLOS:
13. This class of payload has become particularly useful when it comes to missions that are related to plant growth.
14. Which of the following is not a typical payload on a UAS platform?
15. Biomass, crop health, crop yield, and other plant characteristics can be estimated from remotely sensed data using a _________ Index
16. Which of the sensors below are considered optical sensors?
17. uses a laser beam and a receiver to measure the distance to an object.
18. hopping is a basic signal modulation technique used to spread the signal across the frequency spectrum.
19. Which of the following is NOT a sensor type used to collect GIS data?
20. According to the ASPRS Manual of Photogrammetry, Fifth Edition, to be a truly hyperspectral imager a system must have _____ or more spectral channels per image.
21. A cooled ___________ camera’s detectors are typically located in a vacuum sealed case and require extra power to cool. In general, cooled cameras produce a higher quality image than uncooled cameras.
22. Large area monitoring will most likely require the use of ________ platforms,
23. Manufacturers of some sUAS have elected to accommodate interchangeable __________ that can be quickly removed and replaced.
24. UAS platforms have the advantage of offering operators long flight duration for either maximizing time on station or maximizing range.
25. frequency bands are widely used making them susceptible to frequency congestion, which can cause the UAS to lose communication with the ground station due to signal interference.

Set 2

1. When working with radio frequency, LOS and BVLOS:
2. One of the major advantages to _____ is that it utilizes long wavelengths that can pass through most cloud layers, smoke, and dust in the atmosphere.
3. _________ is the term used to describe how the UAS command and control information is sent and received both to and from the GCS and autopilot.
4. ____________ aircraft are vehicles where the lift is created by induced airflow over wings that are affixed to fuselage of the aircraft.
5. COTS stands for ______ ______ ______ ______; COTS is a widely used acronym for many different technologies)
6. SAR systems use ______________ to create highly detailed imagery of the ground.
7. Autopilot equipment is designed to:
8. These sensors generate an image using thermal radiation emitted from every object.
9. Biomass, crop health, crop yield, and other plant characteristics can be estimated from remotely sensed data using a _________ Index
10. As a safety feature of most UAS autopilots, the system can perform a “_________” procedure if communication becomes severed between the ground control station and the air vehicle.
11. These UAS platforms have the advantage of small take off and landing footprints.
