Experimental Processing Centres

Experimental processing centres are candidates to become SIRGAS Local Processing Centres. During a specified time period, they align their processing strategies to those required by SIRGAS and demonstrate their capacity for timely and continuously delivery of weekly solutions. Once they satisfy these requirements, they are appointed as official processing centres. During the test period (usually one year), they process a set of SIRGAS reference stations, but their solutions are not included in the computation of the final SIRGAS products.
