1. cherish: to care for tenderly; love; to keep a feeling deeply and firmly in mind Examples: The old man cherished the girl as if she were his daughter. The child has been away for more than three years and his parents always cherish the hope that he will come back soon

Basic concepts Basic problem: We measure range and phase data that are related to the positions of the ground receiver, satellites and other quantities How do we determine the \ best position for the receiver and other quantities What do we mean by best \ estimate?

The stories of this unit demonstrate how things are not al ways as easy as they look; the grass is not lways greener on the other side.
