SW-115357 - USA (Virginia) - Processing and Coordinate Products Services - Deadline June 26,2026

Vendor needs to provide processing and coordinate products services. – Develop a scalable and repeatable processing framework capable of generating NSRS–aligned coordinates for Geodetic Reference Points (GRPs) associated with CORS not currently included in existing NGS multi–year coordinate solutions.  – The work requires expertise in Global Navigation Satellite System (GNSS) data processing, geodetic reference frames, geodetic network adjustment methodologies, metadata management, coordinate estimation, quality assurance and quality control (QA/QC), and operational geodetic workflows.– Support ingestion and management of GNSS observation data and associated metadata, implementation of multiple independent processing approaches, coordinate validation and uncertainty analysis, and development of coordinate products and supporting documentation.• Processing activities includes:– Ingestion and management of GNSS observation data and associated metadata.– Implementation of PPP and double–difference processing.– Processing of observation windows near reference epoch 2020.0.– Independent validation using additional observation windows and deformation modeling approaches.– Comparison and validation against existing NCN and IGS coordinate products, where applicable.– Coordinate combination and stacking methodologies.– Development of repeatable workflows and supporting documentation.– Generation of coordinate products including associated uncertainties and metadata.
