# Orbit status
#
# Current state of an orbit or loiter manoeuver, published while the maneuver is executing.
# For multirotors, published by the orbit flight task (FlightTaskOrbit) on each control cycle
# when a valid GPS projection is available.
# For fixed-wing, published by FixedWingModeManager during loiter.
# Subscribed by the MAVLink module and streamed to the GCS as ORBIT_EXECUTION_STATUS (message 360).

uint64 timestamp # [us] Time since system start
float32 radius # [m] Radius of the orbit circle. Positive values orbit clockwise, negative values orbit counter-clockwise.

float64 x # X coordinate of center point. Coordinate system depends on frame field: `local = x position in meters * 1e4`, `global = latitude in degrees * 1e7`.
float64 y # Y coordinate of center point. Coordinate system depends on frame field: `local = y position in meters * 1e4`, `global = longitude in degrees * 1e7`.
