GNSSer: objected-oriented and design pattern-based software for GNSS data parallel processing

To cope with the construction and upgrading of GNSS, critical attention must be given to the maintainability, reusability, extensibility, portability, loose coupling capacity and flexibility of GNSS data processing software. Here, using C# and under the .NET Framework, six design principles and six design patterns are applied to a user-friendly GNSSer software, with its purpose being to bridge the gap between the design and implementation of object-oriented methods. Moreover, fine-grained parallel processing is extended. The results from three experiments showed that not only is high positioning accuracy achieved, but the efficiency of GNSS data processing is improved as well.
