内容説明 Review of the 4th edition ?... The growing society of GPS users and designers could be very grateful for the efforts of both the authors and the publisher resulting in the fourth， revised edition of this splendid reference book within six years ... The continous updating and revising make this book an excellent standard reference on GPS for theoreticians and practicians in the future.? Acta Geodaetica， Geophysica et Montanistica Hungarica
