| Abstract: | Magnetic heading sensor V2XG,which senses magnet field with two magneto-inductive sensors,is inexpensive and is easy to integrated into other system.The sensor is used in an UAV heading control system.The interface circuit of the sensor is designed. The algorithms to eliminate constant offset and sensitivity error are given.The final measurement accuray achieves ±2°under a sampling frequency of 5Hz.Application shows that the design has high performance-cost ratio and that the requirement to magnetic heading measurement for UAV flight control is satisfied. |
