The along track error is a function of the nominal touchdown point NTDP, the nominal flight technical error FTE (i.e., how well the autopilot can place the aircraft onto the desired landing spot), the nominal navigation system error NSE (i.e., nominal errors due to noise, multipath, nominal ionosphere, and troposphere decorrelation), and an additional undetected error in form of a bias (e.g., caused by an ionospheric gradient).
