Position tracking system and method for tracking a relative position of connected modules

A position tracking system for tracking a relative position between at least two connected modules, the position tracking system comprising:

• at least one target associated with a first one of the at least two connected modules, wherein the at least one target is at least one of arrangeable on and arrangeable within the first one of the at least two connected modules, wherein the at least two connected module are mechanically interacting entities and/or components, configured for allowing transport of objects from one module to the other module;
• at least one position sensor associated with a second one of the at least two connected modules, wherein the position sensor is configured for generating at least one sensor signal according to a relative position between the at least one position sensor and the at least one target, wherein the at least one position sensor is at least one of arrangeable on and arrangeable within the second one of the at least two connected modules;
• at least one processing unit configured for tracking a relative position between the connected modules from the at least one sensor signal in at least one plane;
• and
• at least one further sensor configured for generating a further sensor signal according to at least one further parameter, wherein the further sensor is selected from the group consisting of:
• a temperature sensor and/or a humidity sensor, wherein the processing unit is further configured for considering the at least one further sensor signal when determining the relative position between the connected modules.
