This upgraded targeting system allows your Auto-Titan to engage enemies with much greater accuracy.
— In-game description.
Guardian Chip is a Tier 2 Pilot Kit that appears in Titanfall. The chip makes the player's Titan more responsive and accurate. Titan will become active right after drop, spending only 3-4 second under protection of the domeshield and instantly joining the battle. It has been replaced in Titanfall 2 by the Assault Chip, now a Tier 1 Titan Kit.
