Presenting DGPS positioning credibility and exchanging ideas at ION ITM 2026 in Anaheim.

Translated uncertainty-diagnosis methods into engineering lessons for DGPS landslide monitoring under multipath, drift, and model mismatch.

The presentation showed how an empirical location test and covariance-consistency checks can distinguish systematic bias from noise-model mismatch in remote monitoring networks.
