Open-source software tools for positioning, navigation and timing

In order to test new algorithms and navigation solutions the institute has started to develop its own inhouse suite of software tools. The INS develops and maintains open-source solutions, which are offered to users after testing and validation. In addition, the exploration and testing of improved adjustment models for positioning and navigation of static and moving objects is another topic of research. These efforts are complemented by studying systematic effects, which set an implicit limit for improving the accuracy of positioning solutions. Among those effects, atmospheric delays and instrumental effects are currently under investigation. These efforts lead an overlap with the research field “Hardware” and there are clear links to aerospace applications, especially to the positioning of nanosatellites. The constantly increasing number of those satellites makes cost-effective solutions possible but requires also precise orbit determination for these extremely low-flying objects.
