DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] Referring to the several views of the drawings, and initially FIGS. 1-4, the fully assembled remote tactical gimbal targeting system (RTGTS) of the present invention is shown and is generally indicated as 10. The RTGTS includes a remote weapon station 20 that is specifically structured for attachment of single or multi-shot anti-armor rocket launcher systems 50 having rocket launcher tubes. The remote weapon station is further structured to be interfaced with aerial, ground and sea vehicles or platforms for operation in mission critical conditions. In the embodiment shown in FIGS. 1-4, the anti-armor rocket launcher system 50 includes two rocket launcher tubes 52, 54, each adapted for firing an anti-armor rocket therefrom.

[0033] The remote weapon station 20 includes a tactical gimbal 30 with a 2-axis control system that operates the azimuth and elevation of the tactical gimbal 30 using remotely controlled electromechanical assemblies. More specifically, motors drive the tactical gimbal assembly 30 to position the rocket launcher tubes 52, 54 on a target via laser range finding and live video feedback equipped with a smart reticle system. The control of targeting and the sequence to operate the Fire Control System (FCS) is achieved via a ground control station by an operator. A radio transmitter 64 communicates with the ground control station to send and receive encrypted signals for operation of the several components of the remote weapon station 20 including the azimuth arm 32, the elevation arm 34, as well as a zoom camera with a multispectral lens and laser range finder (LRF) 92. The zoom camera and laser range finder (LRF) are combined in one unit 92. The tactical gimbal 30 includes an azimuth arm 32 for movement of the tactical gimbal in the horizontal, left and right direction, as well as an elevation arm 34 for moving the tactical gimbal vertically, up and down, relative to the mounting vehicle or platform. The components of the azimuth arm 32, including a motor 62 and motor shaft 63, as well as the radio transmitter 64, are contained within a housing 60 that is formed of a lightweight metal or composite material. The housing 60 is enclosed and sealed by a bottom cover plate 67 and bottom seal 66, as well as a top seal 68 and retainer clip 69. The components of the elevation arm 34, including a motor 72 and motor shaft 73, along with a computer 74 and battery 75, are all contained within a housing 70 that is sealed closed with an outer cover 77 and an outer seal 76.

[0034] The RTGTS 10 is intended to be interfaced to platforms or vehicles utilizing quick release mechanical systems including, but not limited to, the mil spec picatinny rail system, the ARC rail, morse taper or similar high accuracy interface mounting mechanisms with quick release mechanical separation. A mounting plate 36 with a universal quick attachment 38 having adaptive mechanical fastening points serves as the developmental standard platform for accepting these interface options. Adequate surface area and multi-point interface mounts allow for a stiff and balanced platform to support the weight of the RTGTS 10. The RTGTS 10 is designed to be completely modular, platform agnostic for varying situational mounting operation options and able to operate and be used strategically as an attack or defense platform. The RTGTS 10 can also be mounted standard or inverted, allowing the system to adapt to all types of mount applications. The various platforms that the RTGTS 10 can interface with include, but are not limited to, building structures, tri-pods, trees, light poles, unmanned/manned vehicle systems, oil rigs, and numerous other platforms.

[0035] Batteries or other power supply sources are optionally tethered to a main power source 75 or equipped with rechargeable batteries for aerial or active pursuit, or patrol operations and controlled from a remote location. In one preferred embodiment, the main power supply 75 is a 6000 mah rechargeable battery. A main power supply operation, or much larger capacity batteries, can be used for base defense or position defense tactics in a defensive strategy. The rechargeable batteries serve as onboard power supplies for aerials or any remote application needing discrete visualization. The power supply can be integrated to an electronics box or externally configured depending on the capacity requirement per mission. Connectors are universal to adapt to 24v power supplies. The remote weapon station 20 allows for mounting and control of single or multi-launcher systems 50 from the NAMMO developed line of M72 and A12 family of Lightweight Anti-Armor Weapons System (LAWS) anti-armor rocket launchers. Other similar class size rockets to accept in mounting to the remote weapon station 20 can include, but are not limited to, the RPG7, LRAC, ARMBURST and MATADOR. The individual launcher tubes 52, 54 are positively aligned to the frame 40 of the remote weapon station 20 with the FCS installed and snapped into the receiver 82 on the frame 40 that aligns each launcher tube and the FCS to the optics (i.e., zoom camera and LRF). The platform can also adapt to other launcher systems with custom Fire Control Systems. The current multi-shot array of launchers is configured to adapt up to two launchers. Additional motor and gearbox upgrades are anticipated to drive and aim versions of a RTGTS with three or more rocket launcher tubes. The launcher tubes can be replaced after being expensed and the FCS can continue to be integrated into the next compatible launcher model with no calibration necessary. Wiring from the FCS is discrete and paired with the motor wiring to connect the communication box, which is paired with the power supply.

[0036] Targeting is achieved by integrated optics secured to the frame 40 of the remote weapon station 20 that adapts to different launchers and the respective fire control system (FCS), with each launcher tube mounted to the platform individually, but all capable of accurately interfacing with the frame 40. The combined laser range finder (LRF) and zoom camera 92 provide accurate range to target determination and the ability to increase accuracy of success on shots fired from the LAWS rocket launcher assembly. The laser range finder feeds information to the CPU 74 providing position of travel needed, and the tactical gimbal 30 adjusts to range the shot with 400-1000 meters of range accuracy. Motion detection and target acquisition assistance software allows for optimized surveillance and targeting overview. Moreover, motion detection and smart patrol capabilities allows multiple remote weapon station systems to be used in a SWARM or NETWORK driven configuration providing additional visuals and increased response time to threat detection.

[0037] The ability to interface to several platforms allows the range of targeting to be adjusted in the field by an operator with toggle sticks on a visually displayed ground control system (GCS) and relay feedback to the onboard CPU 74. The optical sighting (i.e., zoom camera), laser range finding, and fire control features enable vertical elevation of the tactical gimbal 30 to sight the target and trigger the ignition system. Encryption software protects the tactical gimbal's software from being overtaken or scrambled during operation. The GCS also offers up to 16 total channels to view and customize other components for the end user to integrate if wanted.

[0038] The remote tactical gimbal targeting system (RTGTS) includes high torque motors 62, 72 with geared shafts 63, 73 and load bearings 65, 78 that provide high positional accuracy and target hold that is stable for the operator to confirm visual targets. Each axis (i.e., azimuth and elevation) has a respective motor assembly capable of positioning the azimuth arm 32 and elevation arm 34 to a target directed by the user via the GCS video feed. The universal mounting plate assembly 36, 38 can be easily secured or detached to the platform of choice using a toolless or a readily available mil standard tool such and quarter turn or Allen key. The motors 62, 72 and gear assemblies 63, 73 control the axis in which the LAWS launcher assembly will rotate. This includes the anti-armor rocket launcher system 50 with rocket launcher tubes 52, 54, as well as the frame 40, camera (optics) and LRF 92, fire trigger 86 and safety actuator 87 which all move in unison. The motor 72 and shaft and gear assembly are secured to the metal or composite frame 40 with metal inserts serving as attachment points that assist in stiffening the frame 40. The frame 40 will shroud several strategic points on the launcher tubes 52, 54 with screws and isolators in a way that moves the single or multi-shot systems together in unison.

[0039] The frame 40 is lightweight, quickly manufacturable and designed with universal mounting points and slots that are sized specifically to be compatible with most milspec attachments available in the aftermarket weapons industry typically mounted on armaments. This allows for the frame to adapt for customization. Each launcher tube 52, 54 and its respective FCS are positively aligned to the frame 40 using securing position points for maintaining accuracy of the optics and the FCS. This repeat ability allows for quick swap of rocket launcher tube systems with minimal setup for repeatable operational success. More specifically, the M72 LAWS rocket launcher system attachment structure 82 (i.e., M72 receiver) allows for integration of the LAWS rocket launcher system 50 to the remote weapon station 20 and aligns each launcher tube 52, 54 and the FCS to the optics. The receiver 82 includes a top arm lock 83, a center body holder 84 and a bottom arm lock 85. CAM locks/retainer clips 94 secure the LAWS rocket launcher system to the receiver 82. The receiver 82 is further provided with positioning slots and braces for proper aligned receipt of the launcher tubes 52, 54 onto the receiver 82. The exoskeleton frame structure provides mounting for the motors, communications, computing, optics and FCS. All of which will be sealed or rated to withstand Mil standard environmental ranges.

[0040] Ignition of the rocket will be a remote-controlled sequence of operations with built in safety steps. Each systems FCS will have Ground Fire System (GFS) or an Air Fire System (AFS).

[0041] GFS is mounted on the system surface and is sealed with FCS that utilizes a linear actuator to arm the safety and a electromagnetic solenoid to actuate the existing trigger on the LAWS rocket launcher. These will be housed in the FCS that snaps onto the launchers and provides an alignment and mounting solution to positively align the launcher tube(s) to the frame 40 and provide a secure attachment. Pigtail attachment of the FCS plugs into the frame that connects to the communication box. Each launcher tube style can have an FCS capable of adapting to a range of launcher tube designs developed by NAMMO. The interface of the FCS to the launcher tube clicks into place and then provides a quick connect surface to align and mount to the frame exoskeleton.

[0042] AFS utilizes a firing pin, spring load and manual charging system 86 that can be remotely actuated upon actuation from the GCS. This unit's FCS is attached to the Rocket flash tube and cartridge. An electromechanical linear actuator worm gear drive with a linear actuator shaft face 87 serves as the safety for charging a rear mount FCS. This method provides fail safe bypass to the flash tube and allows for ultimate range of adaptation to units in the field, but may require some alteration. This also provides the ability to reuse the launch tube assembly by inserting a new projectile with flash tube assembly.

[0043] The ignitor is wired from the on-board controller to the rear of the launcher system where the current fuse is located. The launch of the missile will require multiple safety features to ensure at least a 2-phase motion driven by the operator.

[0044] The final ignition option of the rocket fuse assembly that is remotely controlled by GCS is a CADPAD or an electronics fuse that will heat to a point of actuation the powder contained in the housing connected to the flash tube, thereby providing direct control of the system with extreme accuracy.

[0045] Communication includes video, telemetry and system commands of the tactical gimbal 30 and entire remote weapon station 20 will be encrypted AES256 or higher. Currently the GCS utilizes an onboard computer PIXHAWK and command and control signals are transmitted by the HERELINK.

[0046] Multiple remote weapon stations 20 can be controlled or monitored by a GCS during operation. This network of communication NETWARRIOR/ATAK or SWARM will provide a network to give visual motion threat detection built into a surveillance system.

[0047] Since many modifications, variations and changes in detail can be made to the described embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
