Product overview
The BWSENSING BW-AH427C is a Modbus attitude and heading reference system intended for applications including unmanned aircraft, unmanned vehicles and platform stabilization. It measures both dynamic and static attitude, with roll and pitch accuracy of 0.2° and heading accuracy of 0.3°. Its tilt range extends to ±90° in pitch and ±180° in roll, with a maximum output frequency of 500Hz. Additional applications include satellite tracking, underwater robot navigation, drilling equipment measurement and control, marine survey instruments and robot control.
Physical formats comprise a packaged product measuring L60 × W59 × H29 mm and a bare board measuring L44 × W35 × H11 mm. Bare-board length and width may have ±1mm error, with actual product dimensions taking precedence. Selectable outputs include RS232, RS485 and TTL. The system requires 9-36V DC and draws 30mA, reaching 40mA maximum. It features temperature compensation and operates from -40°C to +85°C, with storage limits of -55°C to +100°C. Shock resistance is 2000g for 0.5ms, three times per axis.
