Acquisition   Geolocation Sensor

A wideband receiver for the intercept of commercial communications and waveforms.

ags

The Acquisition and Geolocation Sensor (AGS) is a dual channel, wideband receiver, optimised to support the intercept and geolocation of modern commercial waveforms such as PMR, GSM and satellite-phones. It provides continuous coverage from 100kHz to 3GHz and has a wideband stare capability to intercept frequency hopping signals and civil waveforms.

Features

  • Wideband Coverage with Dual coherent receivers for DF.
  • 40MHz wideband stare.
  • Wideband stepped stare architecture – fast spectrum survey (option: dual-channel for wideband stepped stare DF capability).
  • Integrated GPS provides location, clock conditioning (for accurate frequency tuning) and time-stamping for signal event correlation and TDOA geolocation applications.
  • Standard interface – USB2.0
  • Simultaneous intercept and DF – monitoring, DF and display of four tuned channels (narrowband digital drop receivers).
  • Man-portable – single power supply, small size, low weight.
  • Software defined architecture – receiver control, signal demodulation and analysis implemented on laptop.
  • Frequency hopping signal DF (option)
  • Easy configuration – Windows ®based GUI (RTSAN).
  • Network enabled – AGS units interconnect using a standard IP network via software applications (RTSAN and RTMIS).

Receiver Description

The dual, phase coherent receivers employ 16-bit ADCs, digitising 40MHz of spectrum at a high resolution. This wideband signal is transferred over the USB2 interface for spectral display in the RTSAN software application. In addition to the inherent wideband digitisation, both receivers offer 4 simultaneous and phase-coherent narrowband digital down converter channels (digital drop receivers) to enable DF processing. The receivers can be configured to select between two pairs of antenna inputs enabling concurrent connections to the MicroQuad and QuadTac antennas.

A single receiver can be operated to: capture the full wideband stare; monitor 4 different frequencies within a single band; scan multiple frequencies or bands for signals of interest.
