At any launch base, Real-time tracking and trajectory estimation play critical role during a satellite launch for flight safety as well as mission monitoring. A linear Kalman filter with a novel method of model compensation is designed and successfully implemented for Real time processing of radar data at Sriharikota Range. The verification and validation are effectively carried out using simulated data and the actual mission data of the previous launch vehicles. After validation, the data processing techniques are deployed successfully for launch operations. This paper describes the studies carried out on the above work to implement in Real Time trajectory estimation for 3rd generation launch vehicle LVM-3. Initially basic algorithm is explained with the model compensation technique. Afterwards data processing method for satellite launch vehicle is explained followed by application to nominal and off-nominal trajectories.
