Dr. Les quickly explained to me what TULIP was doing and wanted to do a quick analysis of the same location (i.e. SLAC) using CBG with tri-lateration. So I found a target located at SLAC (134.79.18.134) in CBG list. We ran CBG with tri-lateration for this target. The results were way off. The error distance was of the order of ~3200 km.

Other results are also encouraging, so far I've analyzed around 20 targets, comparing multi-lateration and tri-lateration results. CBG with tri-lateration seems to be performing well.
