Abstract: A method of establishing a system for gathering surveillance data in a hostile environment. The method comprises the steps of providing a movable tractor for ground hauling a trailer, and providing a drone which can be operated independently from the tractor. The trailer has a floor pan for supporting a relay sensor dispensing mechanism and a platform above the floor pan, with a hole for dispensing relay sensors therethrough. The relay sensor dispensing mechanism has an elevator for holding a stockpile of relay sensors, and elevating the relay sensors through the hole. The method comprises disposing at least one relay sensor in the elevator, elevating the relay sensor to a pickup position at or above the platform and retrieving the relay sensor with a drone for subsequent deposition in the hostile environment. The relay sensor then gathers and transceives surveillance data for use and interpretation by an operator. Optional a conveyor chute may replenish the elevator when it is depleted of relay sensors.
