Note 1: Velocity Increment Calculation
- The 5ms velocity increment value output by the accelerometer at time tk is yk (unit: m/s)
- Define the initial value of speed increment accumulation SumVelInt=0
- Define Yk=int [yk * 1e5+δ Yk-1], where int [*] represents rounding operation, and δ Yk-1 represents the remainder after rounding the velocity increment in the previous step
- The remainder after rounding Yk: δ Yk=yk * 1e5+δ Yk-1-Yk
- SumVelInt = SumVelInt + Yk
- Integer range limitation for SumVelInt: If SumVelInt ≥ 1e7, SumVelInt=SumVelInt -1e7; If SumVelInt<0, SumVelInt=SumVelInt+1e7
- After integer processing, limit the range of SumVelInt values to [0,1e7)
- Send the last 3 bytes of SumVelInt after integer processing
Note 2: Angle Increment Calculation
- The 5ms angular increment value of the gyroscope output at time tk is xk (unit: rad)
- Define the initial value SumAngInt for angle increment accumulation as 0
- Define Xk=int [xk * 1e7+δ Xk-1], where int [*] represents the rounding operation, and δ Xk-1 represents the remainder after rounding the previous angular increment
- The remainder after rounding Xk: δ Xk=xk * 1e7+δ Xk-1-Xk
- SumAngInt = SumAngInt + Xk
- The integer range limitation of SumAngInt: If SumAngInt ≥ 1e7, SumAngInt=SumAngInt -1e7; If SumAngInt<0, SumAngInt=SumAngInt+1e7
- After integer processing, limit the range of SumAngInt values to [0,1e7)
- Send the last 3 bytes of SumAngInt after integer processing
