Mobility and control method thereof

A mobility comprising:

• a first global navigation satellite system (GNSS) module configured to generate first location information using a first GNSS signal;
• an internet of things (IOT) communication module configured to receive correction information for correcting the first location information from a base station;
• a first calculation processing module configured to perform calculation of final location information using the first location information generated by the first GNSS module and the correction information received from the IOT communication module;
• and
• a communication interface module configured to communicate with a user terminal that comprises a second GNSS module configured to generate second location information using a second GNSS signal;
• wherein the first calculation processing module is configured to set the first GNSS module or the second GNSS module as a master module and to calculate the final location information using the first location information or the second location information generated by the master module;
• wherein the first calculation processing module is configured to compare a performance of the first GNSS module and a performance of the second GNSS module to set the master module, wherein the performance of the first GNSS module and the performance of the second GNSS module are evaluated using at least one measurement result of a response time or an amount of satellite information using a test signal;
• and
• wherein the first calculation processing module is configured to confirm at least the response time or the amount of satellite information using the test signal, to perform comparison of the performance with respect to at least the response time or the amount of satellite information of each of the first GNSS module and the second GNSS module, and to determine that the performance is higher as the response time is shorter or as the amount of satellite information increases and set a GNSS module with higher performance as the master module.
