Performance Assessment of GNSS Receiver Networks with Software Model Evaluation

Abstract

This work details methods of evaluation for GNSS receiver networks using evaluation techniques implemented in software. Evaluation methods are formulated in this work that estimate the availability and validity rates of GPS receiver data within a GNSS receiver network. These methods are implemented as part of a new software suite developed to handle data from hundreds to thousands of GPS receivers effectively and efficiently. Details of the software suite design and implementation that are critical to the performance and effectiveness of handling large sets of receiver measurement data are detailed. The software and methods developed are applied to the CORS network by evaluating measurement data provided by 708 stations in the CORS network for one day. The rates of data availability and validity are reported, which are used to validate the effectiveness of the software. The results found show that the software is effective for analysis of the CORS network for a large number of GPS receivers.
