ROS and GPS RTK based lawn mower

Snow water equivalent estimation based on GNSS refractometry using the biased up-component and post processing in RTKLIB.

experiments with real-time Precise Point Positioning (PPP)

RTK lawn robot mower

Real-time AI-powered system delivering centimeter-level GPS corrections to autonomous vehicles via ATSC 3.0 broadcast, maintaining sub 3m accuracy. Built for ITU Build-a-thon 4.0 using open-source tools (RTKLIB, etc) with RTK positioning, FEC encoding, OFDM modulation, and neural network optimization. Demonstrating AINN SDG 9 & 11.

ROS driver for Unicore UM982 GNSS receiver with RTK corrections via NTRIP and dual-antenna heading support

Temporal Equivalence Principle: Phase-Resolved Spatial Clock Priors for GNSS Outage Bridging — Satellite-pair & non-common-view clock coherence (λ_T = 4,076–4,348 km, 25–27σ), timing holdover (25 ns at 1 h), k=3–5 degraded-sky PPP, and 68-station live NTRIP ex-ante prediction (116/120 sealed wins).
