of the P.N. Lebedev Physical Institute, Moscow, Russia,
For the optimization of scientific program of RADIOASTRON mission with application of the different angular resolutions (small for the near the Earth diameter baseline projections, medium for near the 28 hours orbit altitudes , and high up to the Moon distances and higher) was fined a new class orbits [1]. One example of such obit is described it the table I.
Here N and t are number of orbit (started from the first apogee)
and time of perigees crossing after launch in October 14, 2000.
Rp and Ra are perigee and apogee radii of the orbit (in ths. km).
T is orbital period (in days). RAn and Dn is right ascension and
declination (in degrees) of the normal to the orbit plane,
RAp and Dp - the same for perigees direction.
The orbit described above allows us to implement both small and large
baselines of observations practically for all sources of
celestial sphere and to ensure an capability of receiving high-quality images
as well as definition of coordinates and own movements of sources to within
micro second of an arch.
We divided the celestial sphere on 1250 parts and
calculated Bmin(i,j) and Bmax(i,j),
The restriction of the communication with the Earth was taken into account
- an angle between "center of the Earth - SRT" vector and source direction
not greater than 90 degrees.
Figures fig.1a - fig.6b show colored distribution of the minimal and
maximal baseline projections for different half years.
Figures fig.7a - fig.7b shows colored distribution of the minimal and
maximal baseline projections for the second half year for 28-hours orbit.
For all other half years the figure look the same.
