T1 Survival is a void mission, Tier One Survival, which is the lowest tier void survival. During void survivals, there are drop rotations of A, B and C. When you enter a void mission, you will start on the A rotation, a new rotation comes up every 5 minutes. So after the first 5 minutes, you will get a drop from the A table of loot. This continues on until you get to drop rotation b and drop rotation c. The rotation order looks like this, A,A,B,C. So to get something from the A rotation, play 5 or 10 minutes, to get something from the B rotation, play 15 minutes, to get something from the C rotation, play for 20. This cycle repeats itself when you have passed 20 minutes. So at 25 and 30, you will get A rotation drops, at 35 you will ge B, and at 40 you will get another C. Use this website and sort by location to find out what drops are in store. http://primarchguild.com/warframe-prime-gear-drop-locations/

Also this is the same for defense and interception missions in the void.

Also Keep in mind the tier, different tiers of the void mission will bring different rewards on their rotations.
