The linear predictor can be based on a first order (Using only velocity) or
second order (Using velocity and acceleration) equation to compute
the prediction.

1st order:
pred_pos = cur_pos + cur_vel / dt * pred_dt

2nd order:
pred_pos = cur_pos + cur_vel / dt * pred_dt
                   + 0.5 * (cur_vel - last_vel)/ dt * pred_dt * pred_dt
