General:
A big brother to Shrakrak, the Nakar (Woodpecker) is a tactical loitering munition and recon drone meant for use by the platoon and company level. The Nakar offers significant and varied payload and endurance while remaining a small enough package for use by dismounted infantry. It can be employed to precisely and effectively engage vehicles (including light armor), infantry and material regardless of cover and at extremely long range in infantry context. It can also be used to provide high quality day and night imagery in real time to the commander of a platoon or company.
Design:
Nakar is an elongated aerodynamically shaped quadcopter, with 4 brushless electric motors on quick attach/detach struts. It has a single stabilizing fin and two rear winglets, with two false winglets at the front. The winglets double as landing skids. At the very front of the drone is the electro-optics package with a gimbaled IR and day camera. The drone also has IR sensors front and rear for automatic obstacle avoidance.
Behind the EO package is the modular payload bay. This allows for quick attachment or detachment of payload modules. The modules can be installed or uninstalled in the field, and merge into the shape of the drone to maintain aerodynamics. The module types are: HEAT (with 300mm of penetration), HE-FRAG (10m lethal radius, tungsten fragments), and an endurance extension payload which is essentially a second battery).
To the rear of the drone are the battery, flight control and communications components.
Nakar is controlled using existing tactical tablets, smartphones or even the Telepat goggles. The use of these devices requires a USB plug-and-play control unit that connects to said device and acts as a radio transmitter/receiver to Nakar. A control unit equipped device can control several Nakar drones, and thanks to Nakar’s autonomous nature, hot swap between them almost seamlessly. As a result a single soldier can have a combined loiter capacity of up to 120 minutes. Schwerpunkt has developed two such control units, one with manual control sticks and one without. If these devices use BASTION II, Nakar can be used to directly upload information to the network.
How it works:
Nakar is typically carried in a specialized backpack package with 2 drones, 4 payload modules and a control device and unit, weighing a total of less than 18kg. When needed the operator removes a drone from the backpack, and plugs the control unit to his device. He selects and attaches the desired payload module, and mates it to the drone, locking it in place. He then activates the drone and device and scans the QR code printed on the drone. This gives the Nakar app on the device the information about the drone, it’s payload and its specific control codes.
An operator preparing a Nakar for use
The operator now commands the drone, but does not have to “fly” the drone. Nakar will automatically take off, loiter, and return to it’s operator. The operator can simply click around a map/satellite top down view and order the drone where to fly to and where to loiter. The operator can also view the drone’s video feed, selecting day/thermal video, controlling the camera direction and zoom. If needed the operator can also manually control the drone, but this is usually unneeded.
To extend the loiter time for recon or fire missions, the operator can hot swap Nakar drones. In this procedure the operator can launch a second drone using the same unit while the other is automatically loitering, and when the replacement drone reaches the loiter area, the first drone will automatically return to base. The station can control up to 5 drones in this manner. In addition Nakar is capable of pre-determined and ad-hoc swarming. When controlled by a single operator they will follow a lead and the operator can swap between them and allocate targets. If they are controlled by different operators, ad-hoc swarming can be done via BASTION II, the drones will follow and loiter with the assigned lead, and the “wingman” operators are only needed when it’s time to engage targets. When used with BASTION II devices, the Nakar can feed target information directly into the C4I system, and BASTION II information will be displayed on both the top down map mode and the video feed.
When identifying a target the operator simply clicks it on the screen, and the drone can be ordered to follow or attack this target. Using pixel identification technology the drone will automatically track targets and attack them with a 0.1m CEP. When attacking the drone will use it’s maximum speed. The angle of attack will be determined automatically by the target size, obstacles, and the payload type. The operator has a simple “wave-off” button allowing him to call off the attack in case of a change in the tactical situation. The payload will not arm unless ordered to attack a target.
In the recon mission or should Nakar not engage a target, the payload can be disarmed, and the drone returns to the operator landing on it’s skids, alternatively the payloads can be ordered to self destruct the drone. The offensive payloads are not reusable without armorer maintenance and should be discarded in combat or collected by ordnance personnel to be made safe and re-used in the future. The endurance extension modules, like the integral battery, can be recharged and reused.
