1.	Which of the following is required to integrate stellar navigation and inertial navigation to get the best estimate navigation solution?(a) Kalman filter(b) Star fix(c) Celestial fix(d) Multisensor processingThe question was asked in examination.My question comes from Stellar Inertial Navigation Theory topic in section Celestial Navigation, Doppler and Altimeter Radars of Avionics
Answer» RIGHT option is (a) Kalman filter Easiest EXPLANATION: Navigational systems use Kalman filtering techniques to integrate all the sensed navigational data to obtain the best estimate navigation solution. The use of Kalman filter to integrate STELLAR measurements requires that STAR OBSERVATIONS and errors be correctly modeled.
