  • Publication number: 20190250277
    Abstract: In a positioning augmentation device (40), a plan making unit (84) selects a subset satisfying selection conditions from within a candidate set that is a set of satellites being selection candidates and saves plan data (43) indicating the selected subset in a memory (72). A plan alteration unit (85) acquires integrity information indicating quality of a positioning signal transmitted from each satellite and detects a satellite of which the quality of the positioning signal does not satisfy quality conditions, from within the subset selected by the plan making unit (84), based on the acquired integrity information. The plan alteration unit (85) replaces the detected satellite in the subset with another satellite included in the candidate set.

  • Publication number: 20190219633
    Abstract: A method and a system for measuring the thermal stability factor of a magnetic tunnel junction device, a semiconductor integrated circuit, and a production management method for the semiconductor integrated circuit, capable of measuring the thermal stability factors of individual devices in a relatively short period of time and quickly performing quality control during material development and at a production site. A meter measures change in resistance value of an evaluation MTJ for a predetermined period while causing a predetermined current to flow into the evaluation MTJ maintained at a predetermined temperature. An analyzer calculates a time constant in which a low-resistance state is maintained and a time constant in which a high-resistance state is maintained from the measured change in resistance value. A thermal stability factor of the evaluation MTJ is calculated on the basis of the calculated time constants and the predetermined current flowing into the evaluation MTJ.
