Borneo and Sumatra in South East Asia are home to a number of orangutan rescue and rehabilitation centres. A common problem each of these have is keeping track of the animals they release back in the wild. Traditionally this is done with ground teams using a radio antenna to search for the weak radio pings each animal sends out. A true needle in the haystack problem.

This talk will discuss a drone-based tracking system that has been developed to alleviate this problem. More specifically the data analysis problem of searching and locating the signal of each animal against a noisy background.
