Raytheon Demonstrator Evaluation
• Raytheon has extensive experience developing 1090 MHz Ground Receivers for SSR Systems
• Developed Extended Squitter (ES) decoder using DO-260A MOPS Enhanced Decoder as a basis
• Made available Demonstrator Systems for evaluation by the FAA at the WJ Hughes Technical Center
![Page 3: Raytheon 1090 ES ADS-B Receiver/Decoder Testing Results Tom Pagano… AD… · · 2013-01-06Raytheon 1090 ES ADS-B Receiver/Decoder Testing Results Tom Pagano, FAA ... -9 0 -8 8](https://reader033.vdocuments.site/reader033/viewer/2022052710/5aaf40077f8b9a6b308d168e/html5/thumbnails/3.jpg)

Test Objectives
• Evaluate to determine if decoder is a MOPS Compliant Receiver Implementation– Measure and baseline performance against
MOPS requirements– Measure and characterize performance in
various 1090 MHz environments • Collect data with 6 sector antenna with 4
receiver channels sectors installed and sited to support Angle of Arrival (AoA) development

Approach
• Ran tests to Measure Performance of Raytheon ADS-B Demonstration System– Sensitivity Measurement– Expanded MOPS ATCRBS Overlap Tests– Expanded MOPS Mode S Overlap Tests– ATCRBS Future High Density Interference
Scenarios– Mode S Future High Density Interference
Scenarios

Page 5
Approach
• Using Raytheon receiver (video output) for RMF decoder processing (MOPS compliant decoder)
• Compared Raytheon to MOPS decoder with same receiver characteristics
• Testing performed on 4 Receiver/Decoder Channels. 2 Demonstrator Systems each with 2 Channels were tested.

Undetected Error Rate
• Undetected Error Rate was computed for receptions recorded during the MOPS tests and the high interference scenarios
• Undetected error rate was about 10-5 for the Raytheon System
• Undetected error rate of the MOPS decoder was 10-6

Conclusion
• The Raytheon ADS-B Demonstrator System meets the MOPS performance requirements for detection in the presence of ATCRBS and Mode S Overlaps tested in accordance with the MOPS
• Raytheon ADS-B Demonstrator System performance in simulated high density interference environments is similar to the performance of a MOPS compliant decoder implementation
