DCS Transmitter Location System (TLS)
2
DCS Transmitter Location System (TLS)Purpose

• Locate and Identify DCS Interfering Radio Signal
  Sources
• Achieve Correction or Termination of Bogus
  Transmission
• Jamming or Blocking Techniques have Proven
  Impractical
• Needed a Practical Centralized Monitoring Method

3
DCS Transmitter Location System
(TLS)Characteristics

• TLS Utilizes Interferometric Techniques to Locate
  Signal Sources
• Uses Adjacent Satellites to Determine Doppler
  Frequency and Time Differentials to Narrow the
  Possible Geographical Area
• Interferometrics TLS of Chantilly, VA has
  Proprietary System for Performing this Service
• They are Currently Providing the Service to the
  Community of Communications Satellites
