DJI S1000:
The above system is one built by the user for custom applications and not a system that is out of the box ready to fly. With this being said there are several possible options for the system as it relates to the mission intended. For this mission a build giving the system a medium range using a radio link AT9 transmitter with a RD9 receiver will enable the system to travel out 650m and easily cover the 400AGL requirement. The system will utilize the DJI NAZA A2 flight controller with intelligent orientation control and banked control mode (DJI, 2015). The A2 comes with both the power management unit (PMU) and the inertial management unit (IMU), GPS and a dual can bus to plug in the needed sensors and gimbal. The A2 will interface with the IOSD MARK II which will record real time flight data of the system and transmit to the ground station via the 2.4 GHz digital video downlink (DJI, 2015). This important information about the internal state of the system will enable the user to ascertain the flight parameters and health of the overall system such as battery amps, mah, pitch, roll, airspeed and altitude (DJI, 2015). The S1000 will carry the zenmuse Z-15-5D 3-axis professional gimbal with internal IMU and infrared module and will house the 22.3 mega-pixel Cannon 5D Mark III camera capable of both still photographs and high definition video at 1080p (Cannon, 2015). The gimbal, with 3 axis rotational control, will be mounted directly under the center of gravity of the copter instead of rails located on the front side of the octocopter thus potentially destroying flight characteristics. The S1000 will utilize the folding gear so the sensor and gimbal can one, move freely and two have a 360 degree unobstructed view. In order to get the highest quality shots and video possible the digital downlink will provide FPV through the airframe mounted video camera. This system was chosen because of its ability to carry a heavy load including all components as well as the camera/sensor. The fact the S1000 comes with folding landing gear adds to the ability to have clean and clear shots and less post production development.
FPV Racer: Black Out Mini-H
The black out mini-h is an h frame quad copter. This quad is built to go fast and due to its size only will carry the a 3S battery, lumenier 12A ESC’s and 2300kv engines, Tyranis X9-D transmitter, Acro Naze 32 flight controller, and a small receiver that can also supply telemetry (battery amps, mah, percentage left) information to the transmitter. The FPV kit is the Fat Shark teleporter V3 which comes with the 5 mega-pixel fixed position HD camera, with SD feature, that will be mounted in the nose of the quad, the 250MW with linear dipole antenna, and the FPV goggles. (FatShark, 2015). This system was selected because of the ease of construction as well as the ability to utilize the sensor/FPV kit that has been tested and proven to work. With this build it’s important to keep the system light so there was no need to use sophisticated components with lots of bells and whistles other than the sensor/payload.
