DCS New Technology Demodulator Development: DAMS NT

1
DCS New Technology Demodulator Development DAMS
NT

• (Demodulator Acquisition Monitoring System
• New Technology)

2
What is DAMS NT ?

• The Application of Digital Signal Processing
  Technology to DCS Demodulator Design
• Implementation of DCS Message Decoding/Demodulatio
  n Using Software Functions Executing Within High
  Speed Signal Processor Chips
• Significant Hardware Size Reduction Compared to
  Present Demodulators
• Allows Software Interface Between DAPS II and
  DAMS NT for Enhanced Computer Control of DCS
  Channels

History of DAMS NT

• Desire for New Demodulator System Coupled to DAPS
  II, Software Based DSP System with DAPS II
  Control Interface
• Task Assigned to ISI (DAPS II Developer)
• RFI Circulated to Industry for Comments
• Two Companies Selected by ISI for Competitive
  Phase 1 Development Issued Contracts for Proof
  of Concept
• DSPCon, New Jersey and Signal Engineering, San
  Diego

History of DAMS NT (Continued)

• Both Companies Conducted Preliminary Design
  Reviews During October 2001
• Live System Demonstration Scheduled for Week of
  December 10, 2001 at the NOAA Wallops Site
• NOAA Team and ISI will Review Test Results
• Production Contract to be Awarded to Most
  Successful Candidate

DAMS NT Pacing Issues

• Critical System Must Process Both 300 bps and
  1200 bps Satellite Data Successfully
• Tight Schedule System Delivery Can Not Impact
  the DAPS II Delivery and Operational
  Implementation
• If BOTH (Performance and Schedule) Conditions not
  met, Then DAPS II Interface to be Designed for
  Current Bank of Demods
