– Power supply: wide voltage input 12~36V
– Rated power: 24W (max)
– Position accuracy up to centimeter level
– Attitude measurement error better than 0.01°
– Operating temperature range: -40~60℃
– Vibration environment: 20~2000Hz, 3.03g
– Rich interface types, support RS232, RS422, CAN and other standard interfaces
– Mean time between failures up to 30000h
The system has a combined inertial/satellite navigation mode and a pure inertial mode.
The satellites that can be received by the GNSS receiver in the inertial/satellite integrated navigation mode satellite positioning information for combined navigation; output inertial solution position after losing signal speed attitude, with meter-level positioning accuracy in a short time.
After the pure inertia mode is started, it has the function of accurate attitude measurement and can output pitch rolling and heading, pure inertia can statically seek north.
