MNS300E Attitude Determination Instrument


  • Accurate parameter calibration
  • Built-in shock absorption module
  • Full temperature compensation.

The MNS300E consists of a MEMS three-axis gyroscope and a three-axis accelerometer. It can meet the performance requirements under different conditions after full temperature calibration. The product provides stable and reliable attitude information, angular rate and linear acceleration information for the carrier through a built-in unique attitude algorithm. The product has the advantages of small size, low power consumption, high reliability and stable performance and can be used in attitude control of vehicle, airborne, shipborne and other fields.
