WebOn lines 4-6 we create *shared_ptr* versions of three newly created *UnaryFactor* instances, and add them to graph. GTSAM uses shared pointers to refer to factors in factor graphs, and *boost::make_shared* is a convenience function to simultaneously construct a class and create a *shared_ptr* to it. We obtain the factor graph from Figure 4. WebAs an initial test, let's run the non-robust optimization script. First, move into the GTSAM build directory. cd RobustGNSS/gtsam/build. Next, the RINEX file saved in the RobustGNSS/gtsam/gnssData directory must be converted to a format readable by GTSAM. ( It should be noted that GTSAM only looks for data files in the …
