**Common Core*
Explain the function of the following communication assets:
A. Satellite Signals Navigation set (AN/PSN 11)
B. Simple Key Loader (AN/PYQ-10)
**Common Core*
a) Satellite Signals Navigation set (AN/PSN 11) - precision lightweight GPS receiver, highly accurate satellite signal
b) Cryptographic Key Loading, Secure Key Management, Data Transfer, Compact and Portable
**Common Core*
Discuss the proper use of the phonetic alphabet, numerals, and prowords
**Common Core*
Used to avoid confusion in reporting information and to avoid EEFI release over comms
**Common Core*
Explain Line of Sight (LOS)
**Common Core*
Direct free-space path that exists between two points, must be no obstructions
**Common Core*
Discuss challenge and password
**Common Core*
The challenge and password system is a critical method for ensuring secure, authenticated radio communication, particularly in military or high-security contexts. It helps confirm the identity of parties involved in communication, ensuring that only authorized personnel are able to send and receive messages, and protects against potential threats such as enemy interception or impersonation.
