I have collected data using the vehicle mounted VB3i IMU integration instrument set up. It is being observed that, the extracted data of LatAcc(m/s2) and LongAcc(m/s2) showing a completely different trend from the Y-Acc(m/s2) ans X-Acc(m/s2) for the same stretch and same time data. The Y-Acc and X-Acc plot shows a completely shifted trend from the Lat Acc (m/s2) and Long Acc (m/s2). Following are the queries regarding the data.
1. How the LatAcc(m/s2) is different from Y-Acc(m/s2) or LongAcc(m/s2) from X- Acc(m/s2)?
2. How the IMU sensor records the data? Is there any particular documentation regarding its data recording technique?
