Fig. 6: Results of the north-finding experiment.
From: Removal of the rate table: MEMS gyrocompass with virtual maytagging
a Experimental setup of north-finding. The MEMS gyrocompass is fixed on the three-axis high-precision turntable. b North-finding results at a fixed position under different working modes: without VM, with VM, and with M. The experimental parameters: 0° (position of turntable), 5 min (time of north-finding), and 200 cycles (number of tests). c Internal coincidence accuracy of the north-finding results under different working modes. The experimental parameters were 0°, ±5°, ±10°, ±15° (positions of turntable), 5 min (time of north-finding), and 3 cycles (number of tests). d North-finding results with 3, 5, and 10 min under different working modes
