PPSDK is a professional software development kit that includes all the necessary tools allowing you to incorporate post-processing functionality into your own applications and products. The API and PostNav, an intuitive GUI application, are the main tools of the development kit. Both tools are based on the same core that drives Septentrio receivers enabling raw measurement data-file processing that results in similar high-precision PVT (position, velocity, time) solutions from your navigation and surveying applications as achievable by using Septentrio receivers.
