Abstract: A reservoir tank assembly may include a housing in which a degassing chamber configured to store coolant is formed, an inlet piping formed in the housing and into which coolant flows, an outlet piping formed in the housing and through which coolant is discharged, and a connection duct fluidly connecting the inlet piping and the outlet piping. The connection duct is disposed through the degassing chamber. Some coolant flowing through the inlet piping flows into the connection duct after passing through the degassing chamber, and remaining coolant is discharged outside of the housing without passing through the degassing chamber.

Abstract: A method of calibrating a global navigation satellite system (GNSS) antenna includes obtaining GNSS measurement data corresponding to a plurality of directions that correspond to a plurality of respective postures of the electronic device, generating integration data by combining the GNSS measurement data corresponding to the plurality of directions, and performing calibration of the GNSS antenna based on the integration data.
