1. A sensor assembly comprising:
a position measurement sensor configured to measure an angular velocity of the sensor assembly inside a wellbore that extends in an axial direction;
a slickline configured to raise and lower the position measurement sensor in the wellbore;
a processor configured to execute a series of measurement units, the series of measurement units comprising:
an inclination measurement unit configured to determine, based upon the angular velocity measured by the position measurement sensor, an inclination of the position measurement sensor inside the wellbore;
a coordinate measurement unit configured to determine, based upon the angular velocity measured by the position measurement sensor, radial coordinates of the sensor assembly inside the wellbore, the radial coordinates defining a location of the position measurement sensor in the wellbore for a radial direction orthogonal to the axial direction;
a depth measurement unit configured to determine, based upon the angular velocity measured by the position measurement sensor, a real-time depth level of the sensor assembly inside the wellbore, and
a data storage unit configured to store a plurality of values, the plurality of values comprising the angular velocity, the inclination, the radial coordinates, and the real-time depth level of the position measurement sensor.
