The purpose of this work is to provide an improved version of multiconstellation GNSS TEC calibration software [29], used by Telecommunications/ICT for Development Laboratory, Applied Physics section, ICTP. This tool is based on an arc-by-arc GPS based TEC calibration algorithm [20]. The current version of the code runs only on Windows operating system and does not use standard libraries,
Furthermore the code is serial and without sufficient documentation. It is very difficult for the T/ICT4D Lab to maintain the current version. A web model based on this tool is running and accessible from ICTP website [30].
Improvements in this tool would also increase the functionality of this published service for external users. Furthermore it would enable us to build on top of this framework a more flexible and scalable service. We start this work from scratch as a new development project, based on C++ (using OOP features) and with the documentation describing the calibration technique. We also make use of existing executables for benchmarking. We were able to achieve impressive performance improvements over current version by integrating standard high performance libraries [27], besides that we now have a software which is well structured, uses OOP features, is well documented, and therefore it would now be possible for T/ICT4D Lab, Applied Physics group ICTP to maintain this software.
