  1. 1. Geolocation Services Provided by Integral Systems Service Solutions (IS3) SSPI Brazil August 16, 2011
  2. 2. Company Composition prior to Merger The information provided in this presentation is proprietary and must not be disclosed unless previously authorized by SAT Corporation
  3. 3. Recent Merger News: ISYS-KTTS • Merger between Integral Systems and Kratos Technology and Training Systems – Is now complete – Mostly business as usual – Expect long range synergies with KTTS in its security services business • IS3 being realigned with Monics® and satID® products under SAT Corporation within the Products Group – Products and Services under one organization – Shared sales and engineering functions better services the customer and end user community The information provided in this presentation is proprietary and must not be disclosed unless previously authorized by SAT Corporation
  4. 4. Who is SAT Corporation? • SAT Corporation has been in the RF Spectrum Monitoring business for over 25 years • SAT has the largest customer base in all regions of the world. >25 operators world wide. • SAT’s Monics® and SAT-DSA® Carrier Monitoring and Interference Detection Products are used world-wide by prominent Satellite Operators and Satellite Service Providers. • SAT’s unique DSP algorithms for Interference Detection and Characterization allow payload operators to “see” under the entire carrier bandwidth • Open Interface: Standard plug and play interfaces to Carrier Planning Tools, Network Management and Flight Control systems • Hardware Independent: COTS hardware commercially available allows flexibility The information provided in this presentation is proprietary and must not be disclosed unless previously authorized by SAT Corporation
  5. 5. What is Interference? • Contamination by extraneous signals, usually man-made, of a form similar to the desired signal • Interference can be: – Planned; due to other signals sharing same frequency (frequency reuse) – Accidental; due to faulty equipment or operator error – Deliberate; with the intention to disrupt communications • Impossible to avoid because the electromagnetic spectrum is limited; many users and services share the same frequency bands, example: WiFi and C-Band. • Important to control (planned interference) • Important to eliminate (accidental or deliberate interference) The information provided in this presentation is proprietary and must not be disclosed unless previously authorized by SAT Corporation If you talk about Geolocation, you must talk about Interference first!
  6. 6. Satellite Communications Interference • Planned, e.g., allocation included in link budget – Rain margin – Adjacent satellite (ITU Recommendations) – Co-frequency • Cross-polarized • Spatially isolated – Intermodulation (earth station and satellite) – Adjacent channel – Sun Interference • Accidental/Deliberate – Accidental, e.g., transmit on wrong satellite, polarization, or frequency – Deliberate – see SatMagazine January 2011, “Challenging Times for Nilesat”, http://www.satmagazine.com/cgi-bin/display_article.cgi?number=80238354 The information provided in this presentation is proprietary and must not be disclosed unless previously authorized by SAT Corporation
  7. 7. Causes of Accidental Interference • Operator error – Operators transmit without coordination – Operators increase uplink e.i.r.p. without authorization – Earth stations under test transmit on wrong satellite, frequency or polarization • Unmanned and remote stations – Faulty equipment not repaired, remote sites may take a long time to repair • Earth station antenna tracking faults • Poorly designed customer networks or VSAT systems – limited control and monitoring abilities, low quality equipment – FM re-broadcast caused by low quality equipment – System design does not consider fail-safe operation – No ability to remotely shutdown individual terminals • Interference from road traffic, emergency services, radar • Intentional interference/jamming The information provided in this presentation is proprietary and must not be disclosed unless previously authorized by SAT Corporation
  8. 8. Ways to Detect Interference • Manual – Wait for customer complaints – Compare spectrum plot of the transponder with the nominal frequency plan – Check for unauthorized carriers, spurious • Automatic – Continually scan signals and transponders of interest, generate alarms for out-of-tolerance conditions • Analog Spectrum Analyzer • Digital Spectrum Analyzer – Pro-active; problem can be cleared before it is noticed by the customer The information provided in this presentation is proprietary and must not be disclosed unless previously authorized by SAT Corporation
  9. 9. SAT Corporation’s Monics® Automatic Monitoring and Alarm Actions Relational Database GUI operating on SQL Server Manual Monitoring with Modulation Analysis Historical Archive Trace Viewing And Reporting….. The information provided in this presentation is proprietary and must not be disclosed unless previously authorized by SAT Corporation
  10. 10. Detecting Interference • Find interference in empty spectrum or within carriers • 80% of the time parametric measurement is all that is needed to resolve the issue. • Check databases to in accidental source.
  11. 11. Detecting Interference Dynamic waveforms • Modulation Analysis on Burst – Operators can zoom in a burst to activate the Time/Power and Frequency/Power display OR PERFORM MODULATION ANALYSIS – Monics displays the Modulation type, the symbol rate and the measured Es/No
  12. 12. Detecting Interference Is it real or just faulty hardware? • What appears to be a CW interference in the signal • Is it real? • Faulty equipment as can been seen by spectrogram, confirmed by constellation diagram which results in what looks like CW interference in the frequency domain
  13. 13. Detecting Interference Carrier in Carrier and Paired Carrier • New Waveforms means New Algorithms are developed • Constellation indicates complex modulation • Monics determines two carriers exist with same power, modulation type and symbol rate • Monics separates signals, measures parameters and looks for Interference
  14. 14. SAT Corporation’s Monics® Equipment Status Monitoring Plan and Status (Dwell Info – Other users on the system) ICONs to other capability Alarm Status Window The information provided in this presentation is proprietary and must not be disclosed unless previously authorized by SAT Corporation
