1. Brief introduction
TY421 is a low cost, high performance, miniature MEMS AHRS. This product uses cost-efficient MEMS gyro and MEMS accelerometer, as well as unique attitude calculation algorithm, can autonomously complete the attitude calculation function in harsh environmental conditions, especially can provide accurately measure the attitude when the aircraft is hovering. Meanwhile, the combination of dual antenna GPS or date fusion of magnetometer can provide reliable and efficient navigation info.
2. Features
(1) Auto-output of navigation information
(2) Meet the requirement of accurate measurement of attitude angle of aircraft, when in large maneuver flight and hovering.
(3) Small volume and weight.
(4) Communication interface RS422、CAN, to be selectable.
(5) Wide voltage input range.
(6) Can complete redevelopment according to customers’ requirement.
