Reception
Richard A. Edwards reviewed The Astrogators Chartbook in The Space Gamer No. 38.[1] He commented: "Considering the cost of photocopying all these maps out of a friend's copy, it is worth buying the book. The types of grids picked for inclusion are the most current in Traveller usage. It is a must for all Traveller referees."
