HCRO NRDZ: Hat Creek Radio Observatory National Radio Dynamic Zone
Project Overview:

Project Goals:

Ìý
Key activities of the HCRO-NRDZ Prototype proposal include:
HCRO environmental spectral assessment including identification and classification of various system types, or activities that generate the most significant interference.
A systematic survey of RF noise around the Hat Creek Radio Observatory.ÌýBaseline RF Noise Survey open data sets will be made available to the NRDZ research community.
Deployment of Google Spectrum Access System (SAS) at HCRO for RA spectrum protection and spectrum sharing.ÌýExtending the SAS framework to include satellite coordination will be investigated.
Exploration into new approaches and architectures for generalized spectrum sharing.
​
The HCRO-NRDZ Prototype activites build upon the original NSF SWIFT University of Colorado Passive and Active Spectrum Sharing (NSF Award #2030233) key objectives:
Analysis and characterization of RF noise with respect to environmental parameters to identify patterns. The team will explore RF noise mitigation approaches based on results.
Exploration of new approaches to dynamic spectrum sharing between passive and active services.
Quantitative analysis of dynamic spectrum sharing mechanisms extended to enable sharing between passive and active services.
Exploration of approaches to optimize the efficiency and security of dynamic spectrum sharing.
Exploration of operational mechanisms for a National Radio Dynamic Zone (NRDZ).
​
HCRO-NRDZ Prototype will make multiple contributions to the scientific community, including:
Tested, documented, and publicly accessible best practices for RF noise measurement.
Documented data and metadata formats for RF noise measurements, and open RF noise data sets to enable multi-institutional collaboration in measurement and analysis.
Tools and metrics for quantitative analysis of dynamic spectrum sharing effectiveness.
Processes for optimizing the effectiveness and security of dynamic spectrum sharing.
Preliminary operational definition and requirements for a NRDZ.
Increased spectrum coordination for protection of RA observations.
Lessons-learned for the general NRDZ research community.
