1. A modular and autonomous assembly for detecting the angular position of the blades of an impeller intended to be mounted on a turbine engine,
wherein the assembly comprises at least one electrical power source allowing the operation of the elements of the detection assembly independently of the turbine engine on which it is intended to be carried, at least one first sensor mounted on a casing enclosing blades of the first impeller and intended to be associated with the first impeller, at least one second sensor intended to be associated with the second impeller, and a main housing including a main processing unit and storage means.
