GLONASS: GLOBAL: MEO: NO

24
Q

why would a country want to design their own PNT satellites when GPS is a free global service?

A
  • Able to deny users on other constellations w/o interfering with their own
  • support their specific needs
25
Q

Who is the primary customer of the L5 band (1176 MHz)

A

Commercial and Civil aviation

26
Q

Chinas PNT system is unique in several ways from other implementations, list at least 3:

A
  • integrated messaging service
  • Augmented by 5G
  • Most satellites active of any other constellation
27
Q

Which GNSS (Global Navigation Satellite Systems) platform provide users with up to 10cm of accuracy?

A

QUASI-ZENITH sat system

28
Q

Why do QZSS and Galileo produce a signal at 1575MHz?

A

to be interoperable with the L1 freq on the GPS constellation

29
Q

Which countries do we consider the primary threats to our space assets/ operations?

A

Russia, China, N.Korea, Iran, India

30
Q

What creates a Denied, Distrupted, or Degraded Space Operations Environments (D3SOE)?

A

A Composite of those conditions and influences in which space-enabled capabilities have been impaired by hostile threats or non-hostile means

31
Q

Categories of interference/ counter space weapons:

  • Electronic (2)
  • Kinetic (3)
  • Non-Kinetic (3)
  • Cyber (not discussed here)
A

  2. Direct ASAT, co-orbital ASAT, Ground Attack
  3. Laser, NUDET/ EMP, High power Microwave
32
Q

What is the difference between jamming and spoofing

A

Jamming: deny, disrupt, degrade the signal

Spoofing: Deception techniques: thinks you are somewhere you are not

33
Q

Describe the difference between Direct Assent ASAT and Co-Orbital ASAT

A
  • Direct Assent ASAT: missile launching from the earth to damage or destroy a satellite in orbit/ easily attributed due to the missile launch which can be easily detected/ directed-ascent ASATs created orbital debris.
  • Co-orbital ASAT: another satellite in orbit is used to attack/ attaching satellites is maneuvered/ easily attributed? debris?
34
Q

Which countries, besides the US, have demonstrated direct-ascent ASAT capabilities?

A
  • China
  • Russia
  • India
35
Q

What is the difference between and in-band laser and an out-of-band laser?

A

In-band: Matches the operating freq of its target, lowest power, “dazzler”

Out-of-band: higher freq than In-band, can damage or blind sensors (perm. damage)

High energy lasers: highest power, can damage, blind, or destroy sensors (payload) or sub-system (bus)
