Calibration and Validation (Cal/Val) Infrastructure

NASA is seeking a subcontractor to deploy and operate a network of ground-based autonomous spectrometers and thermal radiometers for the long-term calibration and validation of satellite-derived data products. The goal is to ensure the ongoing quality, accuracy, and consistency of observational data used in Earth science research and applications. The equipment must function reliably in remote or challenging environments, autonomously collecting high-precision measurements that directly support satellite sensor validation across multiple missions. Operations will require continuous, unattended data acquisition, real-time data processing, and seamless integration with existing satellite calibration frameworks to maintain temporal and spatial alignment with orbital observations. The contract falls under NAICS code 541620 for scientific and technical consulting services, and responses are due by July 29, 2026. While specific performance locations are not defined, the work is expected to span diverse geographic sites to optimize global coverage and environmental representativeness.
