Stonex S900A IMU in the field, short demo on RU-vid. Low GPRS signal coverage. Very precise data with tilt 0°, 30°, 60°. Field software Cube A on Stonex UT10 field controller.
Total different OEM boards, different calculation and precision. You can check technical specifications for both and Hemisphere Phantom 40 has much better spec. If you want to test it, we can help you 😉
