PSS - Persistent Surveillance System


The Persistent Surveillance System (PSS) is an all weather all terrain system designed specifically for rough conflict and war zones. The PSS combines a C4I system, highly capable electro optical sensors (operating in observation and scanning modes) and Radar technologies thus creating a highly reliable, available and redundant Multi-sensor system.

The System is ideal for protecting large perimeters in rough terrains in land, sea and air. The process of detection, identification and targeting is performed automatically, using the best available sensor for the task, based upon the weather conditions, visibility and preliminary configuration of the system. The System enables the operator to concentrate only on the urgent operational tasks instead of monitoring continuously video or radar screens.

The System’s ability to detect threats early and follow their progress automatically meets the highest security requirements and standards. The PSS is the security system of choice for high-value and sensitive sites.




Here are some of the PSS applications:

  • Force protection - Site Security
  • Border (land/sea) Surveillance.
  • Wide - Area Perimeter Protection.
  • Command Control and Targeting.

The main Advantages are:

  • Target-oriented (versus sensor-oriented).
  • Relieve operator stress (Automation, Minimum false alarms).
  • Events Management.

The PSS main components are as follows:

  • Command & Control station with the stronghold software.
  • Aerostat system - SkyStar 300 with EO/IR payload (Speed A).
  • Intruder Detection system:
  • SPIDER system (Electro Optical).
  • Ground Radar System.
  • Remote Video Terminal III (optional).
  • Costumer sensors (optional).


Command & Control Station (CCS):

The Command & Control Station (CCS) primary function is to control and monitor the subsystems sensors and to Act as a C4I center - centralizing data & video from the subsystems.

The CCS is designed to operate a wide range of sensors. It is based on advanced and Aeronautics' proprietary real time software, and Real Time Controller (UMASTM-RTC) hardware.

C4I Center:


The C4I Center is the “heart” of the CCS while the 'Stronghold' software is the core management system for the C4I center. All of the sensors outputs are synchronize into a single accurate tactical display. The station receives all of the data and information from the various connected sensors, processes the data and displays it to the operators. In addition, it enables the control over the sub-systems and sensors that are positioned in the area, and serves as the center for coordinating the response to any developing threat.

The CCS enables the effective pinpointing and monitoring of an attacker’s progress during the vital minutes or seconds as he approaches the scanned area. Those minutes or seconds can deny the attacker the advantage of surprise and enables a successful response.

The CCS has a flexible control interface that can be fine tuned to reduce false alarms and increase operator efficiency.

Skystar 300


The SkyStar 300 is a tactical surveillance aerostat system, which consists of a stabilized day/night Electro Optical (E.O) payload suspended from a helium filled aerostat that is tethered to a ground mooring system. The SkyStar 300 provides prolonged, wide area surveillance coverage from an altitude of up to 1,000 ft, and transmits the surveillance video and data to several different types of control stations.

The SkyStar 300system incorporates a sophisticated Command, Control & Communications package that facilitates effective observation coverage, target acquisition, location and surveillance. This system yields top quality, real-time, day/night surveillance imagery to security or military forces, at a low cost in terms of manpower and logistics.

The aerostat can be operated continuously, at wind velocity up to 40 knots, with a break of between 30 minutes to 1 hour once every 72 hours, to enable refill. When not in use, the aerostat, payload and auxiliary equipment are packed into a truck-loadable container or a van towable trailer.

The aerostat main tether also carries the power supply and a un-jumble, two way communications channel, for receiving payload orientation uplink commands and transmitting downlink video images. The SkyStar 300 system also features an optional wireless data link system.

Command and Control is provided by the CCS console, where separate screens display the downlink video (received on the wire in the tether) and a digital map with GPS location. Raster aerial photos may be used to generate the system maps.

Alternatively, a Remote Video Terminal level 3 (RVT – III), that is a portable control station, based on a hardened PC with joystick control, can control and monitor the SkyStar 300 payload via the wireless data link (optional).

The SPIDER is a high-end panoramic intruder detection system, which automatically detects motion in a wide panoramic view and enables day and night long range observation for recognition and identification of targets.

The electro-optical sensors are installed in a closed and sealed payload, which is protecting it from severe weather conditions. This payload is installed on a two axis gyro stabilized gimbals and enables operation while installed on a tall mast or a similar installation.

The electro-optical sensors include a thermal imaging camera (FLIR), operating in the spectral range of 3-5 micron with a continuous optical zoom lens, a color CCD camera with correspondent optical zoom an eye-safe Laser Range Finder (LRF) and a Laser Pointer (LP).


The SPIDER includes two main modes of operation:

  • Automatic detection of intruders over a wide sector – Scan mode.
  • Recognition and identification of target, day & night from long ranges – Observation mode.

Various types of radars can be integrated into the PSS. The radar's role in the array is to scan and remotely detect and any movement at the protected zone, at all weather conditions, especially those of low visibility.

The radar provides automatic wide area surveillance and tracking of intruding personnel, watercraft, and vehicles. It transmits the detected information to the CCS for response determination.The radar is able to operate in a few modes, that enable the detection of targets at 6 to 12 km (monitoring an area of 12 km in diameter and 24 km in diameter respectively).

The radar can be mounted in several options of installation: on a tower, on a trailer, on the top of a low building, or on some other supporting structure. The recommended height above ground is 8-10 meters for ground monitoring, closer to the ground for over-the-water detections. 





Remote Video Terminal (RVT level III) - Optional


The level 3 RVT is designed for receiving real time video images directly from remote platforms, by units located in the vicinity of the mission area, independently of the CCS. The RVT level 3 allows the user to fully control the remote platform's payload.


Integration of existing sensors - Optional


The PSS fully supprots integration of existing sensors, or sensors of the client's choise. The system's 'open architecture' design supports noumerous types of communication protocols, data inputs and outputs, and display options, in order to offer a flexible and unique solution to any specific requirement.
