What is the most effective way to mitigate against sputtering?
Shielding/Hardening
To mitigate against _______ we bake in a vacuum?
Outgassing
This occurs when space objects collide with atmospheric molecules causing a transfer in kinetic energy?
Atmospheric Drag
This is known as variations in amplitude, phase, and polarization of signals transmitted through a medium?
Scintillation
What provides command and control of the satellite constellations, and generates commands to uplink?
Space Operations Center (SOC)
This part of the RTS sends commands, data uploads, and processor program loads to satellites?
Uplink
This provides an objects azimuth, elevation, and distance from the RTS to perform C2, anomaly resolution and early orbit support
Ranging
What is another name for downlink?
Telemetry
The RTS site with the acronym TCS stands for what?
Telemetry and Command Station
Diego Garcia Tracking Stations call sign is what?
REEF
Thule Tracking Station falls under which Squadron?
23 SOPS
Communicating with the satellite vehicle through the payload is called?
In-Band
This is all of the parts of a spacecraft that support the mission
Bus
This subsystem is known as the “Brains of the satellite” and contains a command decoder
Command and Data Handling Subsystem
True or False
An open-loop control system provides its own feedback without operator input
False
True or False
The Attitude determination and Control Subsystem is responsible for rotational control and satellite payload pointing.
True
Which subsystem is responsible for satellite orbit control?
GNC (Guidance, Navigation, and Control)
This subsystem regulates and maintains the temperature throughout the spacecraft
TCS
True or False
Albedo effect is considered an internal heat source
False
What is considered a transfer of heat between substances in direct contact?
Conduction
What is the only effective method of releasing heat from a spacecraft?
Radiation
True or False
Louvers can be a passive or active method of thermal control
True
What subsystem is responsible for generating, storing, and distributing power throughout the spacecraft?
EPS
True or False
Sun tracking solar panels are considered more complex than body mounted solar panels
True
What is the most common source of power for earth orbiting satellites?
Solar Panels
True or False
Series batteries hold a charge longer and are inherently redundant without a single point of failure
False
True or False
Lithium Ion Batteries are susceptible to memory effect and are not volatile
False
What is when a battery is repeatedly overcharged and builds up electrolyte crystals on the cathodes?
Voltage Depression
True or False
Load shedding is the process of prioritizing components and shutting off power to less vital components
True
This subsystem is the frame that all other subsystems are attached to.
Structure subsystem
True or False
A low cycle structure mechanism can be used constantly throughout the life of the satellite vehicle
False
This is “the science and art of identifying, observing, and measuring an object without coming into contact with it”
Remote Sensing
True or False
Active remote sensing records/measures energy that is externally available
False
What frequency of the EM spectrum do electro-optical sensors use?
Visual light
What frequency of the EM spectrum do PNT sensors use?
Radio waves
What frequency of the EM spectrum do Radar sensors use?
Microwaves
True or False
Electro optical sensors use active remote sensing to capture, observe and record visual EM light reflected and emitted by objects
False
True or False
SATCOM uses both active and passive remote sensing to transmit, detect, record, and retransmit EM radio waves
True
What is a timeline of planned events broken into smaller pieces?
Phasing
This is considering the commanders intent with assumptions and acceptable levels or risk to mission and force
Mission
This is the plan for when things don’t go according to plan
Contingencies
This is an agreement established to drive action outside of a single team that was not previously established
Contracts
What is the goal of a debrief?
Identify mistakes, determine how not to repeat them, and pass on that learning to improve future mission accomplishments
