Abstract:
(EN) [Problem] To calculate an error of a magnetic sensor precisely and quickly. [Solution] A sensor error calculation device 1 is provided with: a GNSS attitude angle calculation unit 20, a GNSS geomagnetism calculation unit 301, and an error estimation unit 302. The GNSS attitude angle calculation unit 20 calculates a GNSS attitude angle from a GNSS positioning signal. The GNSS geomagnetic calculation unit 301 calculates a GNSS geomagnetism from the GNSS attitude angle. The error estimation unit 302 estimates a sensitivity error, a misalignment error, and a bias error of a magnetic sensor by using a magnetic detection value by the magnetic sensor and the GNSS geomagnetism.
(FR) Le problème posé est de calculer une erreur d'un capteur magnétique avec précision et rapidité. La solution selon l'invention concerne un dispositif de calcul d'erreur de capteur (1) comprenant : une unité de calcul d'angle d'attitude GNSS (20), une unité de calcul de géomagnétisme GNSS (301), et une unité d'estimation d'erreur (302). L'unité de calcul d'angle d'attitude GNSS (20) calcule un angle d'attitude GNSS à partir d'un signal de positionnement GNSS. L'unité de calcul géomagnétique GNSS (301) calcule un géomagnétisme GNSS à partir de l'angle d'attitude GNSS. L'unité d'estimation d'erreur (302) estime une erreur de sensibilité, une erreur de désalignement, et une erreur de polarisation d'un capteur magnétique à l'aide d'une valeur de détection magnétique par le capteur magnétique et le géomagnétisme GNSS.
(JA) 【課題】磁気センサの誤差を高精度に且つ素早く算出する。 【解決手段】センサ誤差算出装置1は、GNSS姿勢角算出部20、GNSS地磁気算出部301、および、誤差推定部302を備える。GNSS姿勢角算出部20は、GNSSの測位信号からGNSS姿勢角を算出する。GNSS地磁気算出部301は、GNSS姿勢角からGNSS地磁気を算出する。誤差推定部302は、磁気センサによる磁気検出値とGNSS地磁気とを用いて、磁気センサの感度誤差、ミスアライメント誤差、および、バイアス誤差を推定する。
