Artificial Satellites and How to Observe Them
Every amateur astronomer - and many non-astronomers - will be familiar with seeing a "star" that shows that characteristic steady slide across the starry background of the sky. Artificial satellites can be seen any night, and some as bright as the planets. But how many of us can identify which satellites or spent launch vehicle casing we are seeing? Artificial Satellites and How to Observe Them describes all the different satellites that can be observed without optical aid, including of course the International Space Station and the many spy satellites operated by different nations. Richard Schmude looks at them in detail and describes how they can be observed by amateurs, how to recognize t...
Reference Frames
This book on reference systems is the first comprehensive review of the problem of celestial and terrestrial reference systems and frames. Over 20 years, the importance of this problem emerged slowly as the accuracy of new observational techniques improved. The topic has already been approached in several symposia such as Stresa (1967), Morioka (1971), Perth (1973), Columbus (1975, 1978 and 1985), Kiev (1977) and San Fernando (1978). Two IAU colloquia held in Turin (1974) and in Warsaw (1980) were exclusively devoted to discuss reference systems. During this time, the problem of terrestrial and celestial reference systems has been discussed also in many astronomical and geodetic symposia, bu...
