Processing and Coordinate Products Services

The National Geodetic Survey is seeking a contractor to develop a scalable and repeatable processing framework capable of generating National Spatial Reference System-aligned coordinates. This framework must support Geodetic Reference Points associated with Continuously Operating Reference Stations that are not currently included in existing multi-year coordinate solutions. The agency requires this system to solve the problem of processing and managing Global Navigation Satellite System observation data and associated metadata. The scope of work covers the implementation of both Precise Point Positioning and double-difference processing approaches, as well as the processing of observation windows near reference epoch 2020.0. The selected contractor must perform independent validation using additional observation windows and deformation modeling, and compare these results against existing NOAA Geodesy Community Network and International GNSS Service coordinate products. The project also requires coordinate combination and stacking methodologies, the development of repeatable workflows, and the generation of coordinate products with associated uncertainties and metadata. Eligible bidders must be onshore organizations based in the United States. The agency requires all performance of the work to occur offsite. The agency is currently looking for proposals to determine the budget, and bidders must possess expertise in Global Navigation Satellite System data processing, geodetic reference frames, network adjustment methodologies, metadata management, coordinate estimation, quality control, and operational geodetic workflows.
