What is the maximum number of CORS that OPUS Static can utilize when processing a GPS observation file?

When processing a GPS observation file using OPUS Static, the maximum number of Continuously Operating Reference Stations (CORS) that can be utilized is three. This capability allows for increased redundancy and improved accuracy in the processing of GPS data.

Using three CORS stations can enhance the correction of satellite positioning errors, atmospheric disturbances, and other factors that can affect GPS accuracy. By referencing multiple stations, the processing algorithm can better estimate and apply corrections, leading to more reliable positioning results.

In the context of OPUS Static, which is designed for processing static GNSS data, leveraging three CORS helps to create a robust solution by reducing the potential impact of any outliers or anomalies from individual stations. This method enhances the reliability of geographic positioning and coordinate transformation.

Understanding this maximum limit is crucial for surveyors and engineers when planning their GNSS data collection and processing strategies, ensuring that they can obtain high-quality positional data efficiently.
