Ground Sensors

Ground Sensors

Unattended Ground Sensors (UGS) are a cost-effective solution for covert monitoring of perimeter, borders control or pipeline control. UGS are lightweight sismic sensors which are used to detect people and vehicles.

A peer-to-peer RF network provides robust communications across multiple nodes (sensors) and the network configures itself to determine the most robust path to the Satcom/GPRS gateway that allows the control room to remotely monitor the system.

Technical features

  • Detection range: human 20m, vehicle 30m
  • Number of sensors in the network: from 10 to 1000
  • Deployment life up to 6 months
  • Radio frequency: 863-870 MHz or 902-928MHz
  • Power Source: replaceable lithium battery
  • Temperature range: -10°C / +65°C
  • Gateway wide-area network: SATCOM or GPRS
  • Transport kit: resistant transport boxes

System Description

UGSS automatically detects and classifies objects which attempt to intrude into the monitored area. The system can utilize a combination of different types of sensors arranged in a network. Input from the sensors is collected by a node (sensor) and processed by its on-board signal processor. When signatures are correlated into a detection target, an alarm is triggered and transmitted via radio to a central monitoring station. The VHF radio transmission of control commands and alarm data is compressed and encrypted.

Key features

  • Remote detection and classification of moving objects
