Which of the following is required to integrate stellar navigation and inertial navigation to get the best estimate navigation solution?

Which of the following is required to integrate stellar navigation and inertial navigation to get the best estimate navigation solution? Correct Answer Kalman filter

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.

A chemical solution appears green when the salt concentration is 8 grams per litre (gpl) and red when it is 10 gpl. Pure water was added to the solution of 1 litre of 15 gpl solution till it turned green. Then 125 ml of the green solution is taken out and x grams of salt is added to the green solution to make it red. Another 500 ml of the final solution was taken out and y litres of green solution is added to get a resultant solution of concentration 9.6 gpl.  Assume adding salt doesn’t change its volume and find the ratio of x and y.
