We currently support the processing of:

the United States' Global Positioning System (GPS);
the Russian GLONASS system (GLONASS);
the European Union's Galileo system (Galileo);
the Chinese Navigation Satellite System (BeiDou);
the Japanese QZSS develop system (QZSS).
We are actively developing Ginan to have the following capabilities and features:

Precise Orbit & Clock determination of GNSS satellites (GNSS POD);
Precise Point Positioning (PPP) of GNSS stations in network and individual mode;
Real-Time corrections for PPP users;
Analyse full, single and multi-frequency, multi-GNSS data;
Delivering atmospheric products such as ionosphere and troposphere models;
Servicing a wide range of users and receiver types;
Delivering outputs usable and accessible by non-experts;
Providing both a real-time and off-line processing capability;
Delivering both position and integrity information;
Routinely produce IGS final, rapid, ultra-rapid and real-time (RT) products;
Model Ocean Tide Loading (OTL) displacements.
The software consists of two main components: Network Parameter Estimation Algorithm (PEA) and Precise Orbit Determination (POD).

The General Mission Analysis Tool (GMAT) is an open-source space mission analysis tool. Found via https://destevez.net/2022/09/more-qo-100-orbit-determination/
