Inertial Sensor

Product description

SAST has developed many FOGs including Four-axis FOG, Small Four-axis FOG and FOG Integrated Navigation System. Three orthogonal gyros and a skew gyro compose the FOG, through redundancy configuration to enhance reliability of FOG, which has the characteristics of small volume, low consumption and light weight, which is suitable for medium and low orbit satellites. FOG Integrated Navigation System, composed of 3 FOGs and 3 quartz accelerometers, has the function of strap-down computation and integrated navigation, featured with high reliability and high precision, which can be used for navigation in the fields of aviation, aerospace and voyage, etc.
