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
Who is the primary customer of the L5 band (1176 MHz)
Commercial and Civil aviation
26
Chinas PNT system is unique in several ways from other implementations, list at least 3:
- integrated messaging service - Augmented by 5G - Most satellites active of any other constellation
27
Which GNSS (Global Navigation Satellite Systems) platform provide users with up to 10cm of accuracy?
QUASI-ZENITH sat system
28
Why do QZSS and Galileo produce a signal at 1575MHz?
to be interoperable with the L1 freq on the GPS constellation
29
Which countries do we consider the primary threats to our space assets/ operations?
Russia, China, N.Korea, Iran, India
30
What creates a Denied, Distrupted, or Degraded Space Operations Environments (D3SOE)?
A Composite of those conditions and influences in which space-enabled capabilities have been impaired by hostile threats or non-hostile means
31
Categories of interference/ counter space weapons: - Electronic (2) - Kinetic (3) - Non-Kinetic (3) - Cyber (not discussed here)
1. Jamming, Spoofing 2. Direct ASAT, co-orbital ASAT, Ground Attack 3. Laser, NUDET/ EMP, High power Microwave
32
What is the difference between jamming and spoofing
Jamming: deny, disrupt, degrade the signal Spoofing: Deception techniques: thinks you are somewhere you are not
33
Describe the difference between Direct Assent ASAT and Co-Orbital ASAT
- 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
Which countries, besides the US, have demonstrated direct-ascent ASAT capabilities?
- China - Russia - India
35
What is the difference between and in-band laser and an out-of-band laser?
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)
