SCANNER UAV

 

Scanner  

The  Scanner is a medium endurance unmanned aircraft system. The  Scanner’s primary mission is reconnaissance and surveillance in support of the operational commander. Surveillance imagery from video cameras and forward looking cameras are distributed in real-time. 

Features

 The  Scanner is a system, not just an aircraft. A fully operational system consists of one aircraft (with sensors), a Ground Data Terminal, an Image Receiving System, a  Scanner Satellite Link, along with operations and maintenance crews for deployed 24-hour operations. 

The basic crew for the  Scanner is a pilot and a payload operator.  Scanner follows a conventional launch sequence from a semi-prepared surface under direct line-of-sight control. The take-off distance is typically 50 m (165 ft) and landing 100 m (330 ft).

 The mission is controlled through real-time video signals received in the Ground Data Terminal. Command users are able to task the payload operator in real-time for images or video on demand. The surveillance and reconnaissance payload capacity is 10 kg (22 lb), and the vehicle carries electro optical and infrared cameras. The aircraft can be equipped with sensors as the mission requires. The cameras produce full-motion video. 

The system is composed of three major components, which can be deployed for operations in the field. The  Scanner aircraft can be disassembled and packed into a container for travel.

 Background 

The  Scanner system was designed in response to the needs of police and military to provide medium-duration intelligence, surveillance and reconnaissance information.

 It has many other uses: promotion, real estate sales, technical documentation of historic buildings, digs registration, comparison of geological changes, agriculture, detection of illegal buildings and junkyards, searching for missing persons or fugitives, measurement of concentrations of noxious gases, traffic monitoring, residential area monitoring, and security patrol.

ARCA (Adaptive Routing and Conflict mAnagement) control system 

The goal of the project is to develop an autonomous on-board flight system able to guide a UAV towards a specific destination modifying its own flight trajectory in reaction to a variety of external situations, maintaining the separation with other aircrafts. In restricted airspaces this system will allow a UAV to separate from other UAV by coordinating with them and autono mously solving possible trajectory conflicts. The system will also offer the same capabilities for the non restricted airspace, including separation from commercial aircraft. This capability will only be exploitable if particular operational conditions are met (e.g. all commercial traffic is equipped with devices for providing navigation information such as the ADS-B; adequate ATM procedures are defined to deal with equipment failures). Path Planning and Conflict Detection & Resolution functionalities with an innovative  approach based on the emerging  frameworks  of Multi-agents  Systems  and Game
Theory.
Inspection; Assessment and Monitoring; Scientific Mission Participation, and others. Although many aircraft currently allow an autopilot to be programmed by providing waypoints, most require an element of human piloting when routes are modified.

UAV AUTOPILOT

 

Autopilot Overview 

The autopilot is designed as a modular system consisting  of  a UAV  Control  Unit  and  various sensors (GPS,  gyroscope,  accelerometers, altimeter,   …) communicating   through  two independent CAN buses for high reliability. The data collected by various sensors is combined by a unique algorithm statistically evaluating validity of the data. Data from one particular sensor are merged with data obtained by another sensor based on sensor noise probability guess, which leads to more precise calculation of the UAV’s state.  This   topology   benefits   from   using  of redundant  sensors  that  are  working  simultaneously  without  switching.  When  sensor  malfunction  occurs,  only  noise  probability  increases. Classical switching to backup device does not use all available sensors during normal operation.

 
UAV Control Unit

Features

 The key feature of the autopilot is to stabilize the aircraft. The considered variables are: 

•  direction (heading)
•  horizontal speed
•  altitude 

The controlled variables are:

•  control of the engine thrust
•  aerodynamic control surfaces (roll, pitch and yaw)

 The heading is controlled by a combina- tion of deflection of the rudder (or elevat- ors in case of the rudder-free airframes) and  ailerons.  The  horizontal  speed  iscontrolled  by  adjustment  to  the  enginethrust. The rate of climb to a given altitude is achieved by the application of a combination of elevator deflection and engine thrust.

Automatic Flight Control System 

The Automatic Flight Control System (AFCS) – higher level intelligence of the autopilot – which accepts the commands from the operator (respectively UCS), compares the state (orientation, position, …) of the UAV with what is commanded and instructs the other layer of the system to make appropriate corrections. It contains the memory to store mission (a list of way points and how to fly through them) and flight program able to react to unpredicted events. 


GROUND CONTROL SYSTEM

 

UAV Control System

 The  UAV Control System (UCS) is a NATO STANAG 4586 compatible system designed to control  400 aerial targets and other STANAG 4586 compatible UAV or UGV and UUV. The system is not limited to one vehicle at a time but can receive telemetry data and sensor imagery from multiple vehicles in parallel thereby enabling it to combine data from several sources and  control  several  vehicles  and  their  payloads.  According  to  STANAG  4586  multiple  levels of interoperability are feasible between different UAVs and their UAV Ground Stations (UGSs). To achieve maximum operational flexibility the UCS supports Level 4: Control and monitoring of the UAV, less launch and recovery.

UCS Architecture 

All  UAVs  controlled  by  the  system  communicate with Core UCS (CUCS) through STANAG 4586 defined Data Link Interface (DLI). The CUCS unit processes the telemetry and other data collected from   the  UAVs.   The  data  is   provided  further to compatible  C4I  Systems  and  through  Human Computer Interaction (HCI) module to the vehicle and payload operators.

 UCS Configurations 

There are several configurations of the UCS available to meet specific requirements of various missions. Mobile configuration is designed to provide basic functionality focusing on maximum mobility  and  easiness  of  use  in  complicated  situations.  Room  and  Car  configurations  offer a reasonable trade-off between full featured functionality, lower mobility and more complex human- computer interaction requiring more qualified operators.

Payload Control 

The payload carried by the vehicle can be sensor systems and associated recording devices that are installed on the air vehicle, or they can consist of stores, e.g. weapon systems, and associated control/feedback mechanisms, or both. The data link element consists  of  the  Air  Data  Terminal  (ADT) in the air vehicle and  the  Ground   Data Terminal (GDT), which may be located on surface,  sub-surface  or  air  platforms.  The control of the UAV System and communication with its payloads is achieved through the UCS and data link elements. The UCS element incorporates the functionality to generate, load and execute the UAV mission and to disseminate usable information data products to various C4I systems or a custom external system.
