System for modem array fault tolerance

A method comprising:

• establishing a first data connection between a first processor and a first modem;
• establishing a second data connection between the first modem and a second modem;
• establishing a third data connection between the first processor and a third modem;
• establishing a fourth data connection between the third modem and a fourth modem;
• determining a failure associated with the first modem;
• discontinuing sending first data associated with cross-polarization interference cancellation (XPIC) between the first modem and the third modem using a fifth data connection;
• discontinuing sending second data associated with XPIC between the second modem and the fourth modem using a sixth data connection;
• and
• transferring network data between the second modem and the first processor via the sixth data connection, the fourth data connection, and the third data connection.

A satellite comprising:

• an antenna;
• a radio-frequency (RF) front end connected to the antenna;
• a first modem, a second modem, a third modem, and a fourth modem, wherein each modem is connected to the RF front end;
• a first processor executing instructions to:
• establish a first data connection between the first processor and the first modem;
• establish a second data connection between the first modem and the second modem;
• establish a third data connection between the first processor and the third modem;
• establish a fourth data connection between the third modem and the fourth modem;
• determine a failure associated with at least a portion of the first modem;
• discontinue transferring first data associated with cross-polarization interference cancellation (XPIC) between the first modem and the third modem using a fifth data connection;
• discontinue transferring second data associated with XPIC between the second modem and the fourth modem using a sixth data connection;
• and
• transfer network data between the second modem and the first processor via the sixth data connection, the fourth data connection, and the third data connection.
