Publisher's Synopsis
This was the first COSPAR symposium devoted to Relativistic Gravitation. Activity in testing Relativistic Gravitation has increased considerably in the past two decades with the rapid growth of technical capabilities. The development of space-worthy laser, gyroscopes, atomic clocks, cryogenic equipment and low noise microwave receivers combined with highly sophisticated deep space technology and communication systems allow precision tests of relativity and gravitation and this technological progress is described within this publication.
