In infrastructure-intensive and hazard-prone economies, disaster risk is not merely an external contingency but a cumulative outcome of how physical, industrial, and digital systems are measured, regulated, and operated across their lifecycle. This article advances a measurement-based governance framework for DRR by extending the Aswal Model of National Quality Infrastructure and integrating metrology, standardization, accreditation, and conformity assessment into the disaster risk reduction cycle. The framework places continuous, traceable, and uncertainty-aware risk assessment—covering hazard, exposure, vulnerability, and capacity—at the core of governance, while interpreting preparedness, mitigation, response, and recovery as parameter-driven and auditable functions. A traceable measurement-to-governance chain is introduced to demonstrate how calibrated observations and validated models, supported by uncertainty characterisation and standards-based traceability, translate into decision thresholds, regulatory instruments, and operational actions, with audit and feedback enabling continuous improvement. The paper further shows how national disaster-risk policy, including the Prime Minister’s 10-Point Agenda on Disaster Risk Reduction, can be operationalised through existing quality-infrastructure mechanisms without institutional duplication. By embedding DRR within national quality infrastructure systems, the framework strengthens regulatory coherence, institutional reliability, auditability, and adaptive learning, highlighting the expanding role of measurement science as a foundational instrument of credible and resilient risk governance.</p></div>","PeriodicalId":689,"journal":{"name":"MAPAN","volume":"41 3","pages":"765 - 777"},"PeriodicalIF":1.4,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148903371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detecting such attacks requires the receiver to distinguish these abnormal patterns from the naturally stable characteristics of genuine signals. This study evaluates the vulnerability of NavIC to spoofing through a series of controlled static experiments and assesses the performance of commonly used statistical detection techniques. The analysis focuses on pseudorange and Doppler measurements, as these parameters consistently show early deviations when counterfeit signals are introduced. To the best of our knowledge, this is the first study that systematically compares multiple statistical detection frameworks (e.g., the Generalized Likelihood Ratio Test (GLRT), Mahalanobis distance) using NavIC-specific observables such as inter-satellite pseudorange and Doppler variance under spoofing conditions. Among the approaches examined, the Generalized Likelihood Ratio Test (GLRT) demonstrates the most reliable detection capability across different spoofing conditions. Time-series observations further highlight the inherent stability of NavIC’s GEO/GSO satellites, which restricts the effectiveness of spoofing attempts by making departures from normal behaviour more noticeable. The results suggest that NavIC’s constellation geometry naturally supports early spoofing detection, and that coupling these features with machine-learning-based classifiers in future work could enhance robustness against a wider range of spoofing strategies.</p></div>","PeriodicalId":689,"journal":{"name":"MAPAN","volume":"41 3","pages":"789 - 802"},"PeriodicalIF":1.4,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148903496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
