MH-TY421 is a low cost system which can be used in simple vehicle navigation “Satcom on the move”antenna platform stabilization. This MEMS gyro,MEMS accelerometer, as well asalgorithmsuitable for conical scanning of antenna and satellite data correction this system uses, makes the requirement of hardware reduce greatly. Finally, the combination of dual antenna GPS or magnetometer can provideprecise navigation and position info for users.
(1)Auto-output of navigation information
(2)Meet the requirement of accurate measurement of attitude angleof aircraft, when in large maneuver flightand hovering.
(3)Small volume and weight.
(4)Communication interfaceRS422、CAN, to be selectable.
(5)Wide voltage input range.
(6)Can complete redevelopmentaccording to customers’requirement.
