Very important changes proposed to navigation being implemented from today 01.04.26….
Today we’re thrilled to announce a trial of Adaptive Grid North - a rotation of Grid North on OS maps, boldly future‑proofed and simplyfing navigation for generations to come.
What does this mean for navigating?
For anyone keen to get ahead and test the new system early… hold your existing map at a jaunty angle, or tilt your head for the same effect. No compass required. And if you do get lost, congratulations: you now have a scientifically approved excuse.
As Dr. Polly Axis, Senior Orientation Specialist at OS, explains: “Our long‑range modelling indicates that aligning magnetic north with Grid North through a proactive macro‑rotational intervention could reduce theoretical navigational ambiguity by up to 0.00003%. The reassurance explorers gain from knowing their map is ‘pointing in the right direction’ for the next century should not be underestimated.”
