Sensor Spines are a T'au vehicle support system that consists of several highly-sensitive antennae mounted on the prow of the vehicle.
These Sensor Spines aid the vehicle by feeding data to an advanced ground-following flight control system, thus plotting safe courses through treacherous terrain and avoiding traps or mines that might lie hidden out of sight.
