Wuxi Bewis Sensing Technology LLC is one of the leading China 9d full attitude digital compass module manufacturers and suppliers,Website:://.inclino-meter.com, welcome to wholesale high quality 9d full attitude digital compass module from our factory.Unmanned vehicles are performing progressively more complex tasks-and requiring increasingly robust and accurate heading and orientation information. But existing AHRS modules leave too much room for error. They lose heading when encountering magnetic distortion; they suffer from errors when experiencing erratic motion; and often don’t provide accurate headings, even in a static environment. And at more than $2000 for a MEMS-based AHRS, it’s no wonder AHRS have only been integrated by a select few customers. So when there’s no room for error, HEC395 stays on track. The new HEC395 AHRS provides unparalleled heading accuracy when static, while moving and when encountering magnetic distortion. HEC395 employs a patented Kalman filtering algorithm that intelligently fuses Magnetic Sensors with gyros and accelerometers to overcome errors due to erratic motion and changes in the local magnetic field. And HEC395 is priced for commercial use — delivering more reliable heading than AHRS modules that cost twice as much.High Accuracy RS232/RS485/TTL Optional Widely working temperature: -40℃～ 85℃ Low power consumption Hard and soft iron correction with quality of calibration score 5 user calibration procedures
