Positioning Algorithm and RTKLIB (2nd & 3nd Days)

1. Basic theory for GNSS data analysis
The theory for GNSS data analysis including signal structure, models  of observables, algorithms for least square estimation, error sources and their mitigation and integer ambiguity resolution. It focuses on carrier-phase based precise positioning techniques like RTK and PPP.  

2. Introduction of RTKLIB
An introduction of RTKLIB which is an open-source software package for GNSS data analysis. It includes program structure, AP functionality, usages of API, supported standard data formats and models involved in RTKLIB.

3. Practice of GNSS data analysis with RTKLIB
A practice of GNSS data analysis by using RTKLIB. It includes the usage of APs: RTKPOST, RTKNAVI, RTKPLOT and RTKCONV, options setting and detailed instructions to deal with real GNSS data for both of post-processing and real-time.

4. Advanced Topics
It provide some advanced topics in GNSS precise positioning technology.
