AT Ground Surveillance System (GSS)

AT Ground Security Sensors 

The AT Ground Surveillance System (GSS) is integrated network of sensors, cameras and mesh radio network providing early warning alerts and visualization of potential threats. The AT GSS when integrated with the AT SA Situation Awareness System provides field users relevant real time information similar to that available to coordinators in command bases stations. The combination of position, sensor alerts, video and status from multiple sensors combined on the one system screen provides significant efficiency to make rapid decisions in demanding operational scenarios.

AT GSS Sensor components

• iScout®
• vWatch®
• Air-Drop Sensor
• Radio Transceiver
• IR Camera
• IP PTZ Camera

The AT GSS provides both short term and long-term deployment solutions without reliance on fixed infrastructure, enabling remote area monitoring and security alerts for critical assets and deployed teams. The AT GSS sensors can be used for applications includingpersonnel, assets, facility perimeter and border security monitoring, and intelligence and counter-intelligence, expeditionary and counter-insurgency tasks. Application examples include critical infrastructure such as Nuclear Plants, Refineries, Jails, Airports, Military bases and Shipping Ports.

AT GSS Sensor component detail

iScout® - The iScout® is a small solar powered, water proof, point-to-point radio with advanced detection performance at a low price. iScout® takes less than 1 min to install and is the size of a deck of playing cards, making it simple to conceal. iScout® can be configured for seismic, acoustic, magnetic, tamper and thermal detection. Any or all of these modes can be combined in network of sensors integrated in the AT SA system.

Key features

vWatch® - vWatch® is a portable and remotely controlled image/video management systems that manages encrypted video distribution and video quality over the AT GSSnetwork. When combined with the vWatch field unit a user can adjust PTZ and image detailsettings and the system will dynamically adjust the data rate to match the availablebandwidth and stream requirements. 

The vWatch has several power supply options and a USB connector to power external devices. The vWatch® device is rugged and built to work in harsh weather conditions. A display shows the status of the unit and the IP address to provide confirmation on installation that unit is streaming video to the server. 

The Field Unit has the option of 4G LTE service,WiFi or wired links with smart data throughput management to control video streams over cellular links with monthly data limits. 

The vWatch® Video Management Coordination Server and supports a large number of vWatch® Field Units. The Coordination Server stores the video for replay and analysis and distributes the video to many users for computer, tablet or AT SA Situaational Awareness Terminals. 

The vWatch® Coordination Server software consists of Microsoft server software, map server software, database management software, video viewer translation software, Web server software, Connection Manager software, target activity sensor Situation Awareness Display (SAD) software, OmniPush XML integration software, and encryption/decryption software.

McQ Air Drop Sensor

For hard to reach areas or for rapid deployment application, the AT GSS can be supplied with Air Dropped ground sensors. The sensors are dropped from either a fixed wing or helicopter aircraft and are designed to survive a freefall. The system has a self-contained mechanism to self-right upon landing. 

Sensors are solid state, can be camouflaged and include surveillance, communications and also weather stations providing temperature, humidity, barometric pressure, visibility, wind speed and direction.

Radio Transceiver - The AT GSS mesh radio network delivers encryptedhigh speed sensor-to-server communication for collection, transport and control of sensor data, as well as remote management and configuration of deployed sensors. The AT GSS radio transceiver uses 128 or 256bit Encryption to deliver up to 100km line of sight range with intelligent network monitoring and user selectable frequency hopping sequence. 

With extremely high data rate and energy independence The AT GSS Radio provides a flexible, modular and mobile solution to traditional microwave networks. The system is optimized for image and video data exchange and is fully integrated with the AT SA Situational Awareness System and the Ground Sensors for powerful multi-level distributed networking.
