Baseline distance erodes single-base RTK as atmospheric and other errors stop matching between base and rover. See representative accuracy degradation (≈0.6 cm near the base to ≈3.1 cm at 50 km) and how network RTK models regional errors to keep results steadier.

Multipath and signal blockage are common reasons an RTK Fix drops out or looks “good” while being wrong in cities, forests, and mountains. You’ll get a field checklist for mitigation—site choice, antenna placement, and QC signals like Fix/Float transitions and DOP limits.
