GeoPose class

GeoPose is a GPS position and orientation, optionally with altitude.

Orientation is expressed in the east-north-up tangent frame at location: +X east, +Y north, +Z up. Viam base axes are +X right, +Y forward, and +Z up, so the identity orientation (o_x, o_y, o_z, theta) = (0, 0, 1, 0) is level and faces north: forward is north and right is east.

The same rotation as an orientation vector is Viam's Tait-Bryan Euler sequence, intrinsic z-y'-x'' (yaw, then pitch, then roll), in degrees:

  • yaw: right-handed rotation about local up (+Z). Zero faces north. Positive yaw is counterclockwise viewed from above, so a compass heading in degrees clockwise from north is the negation of yaw.
  • pitch: right-handed rotation about the base's forward axis (+Y).
  • roll: right-handed rotation about the base's right axis (+X). With pitch 0, positive roll raises the forward axis; that angle is the elevation of forward above the local horizon.

Exactly one of heading or orientation_vector is set. heading is only the compass yaw of a level pose (pitch 0, roll 0). It is not added to orientation_vector.
