Tools
The workbench: focused calculators and planners you can reach for mid-task, each one wired to the same numerics that power the lessons — so the tool and the explanation never disagree.
What’s coming
- Coordinate converter — geodetic ↔ ECEF ↔ ENU, with the frames explained inline.
- Satellite geometry & DOP planner — check HDOP/GDOP for a time and place before you go collect data.
- Pseudorange / least-squares sandbox — feed in measurements, watch the solution converge.
- Unit-safe by construction — every input labels its units; no hidden conversions.
Meanwhile, the lab is open.
Interactive lessons and guided paths are live now. Start building the mental models the rest of the platform will be built on.
