EP Running Fix vs. the Traditional Running fix -- Part III. The evolution consecutive running fixes. Successive running fixes emphasize the difference between the two estimation methods: The first figure below shows consecutive EP running fixes, the 2nd figure shows consecutive traditional running fixes. As you can see, uncertainly in the EPRFs are continually corrected, and limited, by succeeding LOPs. For comparison, the 2nd figure shows the TRF results using the same LOPs and DR estimates. The track and fix locations vary radically, with some fix locations beyond possibilities. (Also the TRF is even a bit more messy and more plotting work.)
