PREPARED AND DISSEMINATED BY CENTRAL INTELLIGENCE AGENCY .O of 1.1G(~~ ~I NO. Of IK?l. CO 3Oit 57, A. A. Htagouravov aff're a per discussing the lifetime of the satellite. Be wished to leave the Impression that the set of eoodittms he postulated vere purely hypothetical and had no relrtiooship to the Ressian program. (Obviously, if the imssians bad made all of these calculations, they were going to use them.) These calculations were based on the satellite's being 10 kilograms in weight and Ming a diameter of one-half meter. This Would be comparable to the U. B. satellite. 2. The above data were based on the presumption that the orbit bad a perigee of 360 lma and apogee of 700 Ins. Then Bta.onravov gave data for three o'.hrr sets of cond1tixs which really gives information ot, what the Puasiane think densitier in the atnospbere are at these heights: a. F rigee - 200 kaa Apogee 360 kr.s I.ifetiar of satellite 3 days b. Perigee - 360 +ans Apogee 800 i s Lifetime of satellite 15 mos. _ fetIald ? _...-r.

Be said two significant things: (1) They felt that EuiCai.ce vas t_he =---at ccplicnted engineering problem they had. (2) She Russians had triedke clear that they were not too concerned about !racking on .heir first orbit attespts because they expected these to be vay off the predicted courr.e. Later they said they vould try to be nave precise. (These two statements go together. They indicate the Riss:an methods or approach is a luckshot one since their guidance is weak.) j. It has beccs, very erioent that they viii not use 108 megacycles in their early attearte; that the frequencies of the radio emission will be 20 and 40 megacycles. When pressed, ifasatkin did indicate that 108 rsgeeycleq might veil be Included in our next series of satellites It vas impossible to determine what was meant by this phrase. Be was asked vt,ther the isssians would entertain any sort of action as the part of this country or of CSAWI to ensure this 108 nagacycle use amd be indicated that really nothing could be done. If they were going to do it, they would do it without any further request.

The Rrsaians accepted this as a resolution.
