Design Parameters and Efficiency of a Space System for Warning about Small Celestial Bodies Approaching the Earth along Collision Trajectories . ... tracking of an earlier detected hazardous celestial body (HCB) for synchronous-basic position measurements. The space telescopes (ST) would be placed at a long distance (such as 5 10 7 km) from the Earth to provide for detecting small (100 m) celestial bodies when they are moving to the Earth from the sunward direction. ...

... Parameters of the Moon-perturbed orbit . ... From orbits consistent with this limitation and with the date of the launch October 1, 2000 as an example, an orbit was selected with apogee directed to the North Galactic pole at the begining and rotation of orbit plane was maximized. The initial state vector is given in the inertial coordinate system in epoch J2000.0. ... The orbit has initial perigee radius Rp=7000.0 km, initial apogee radius Ra=343000.0 km and initial period T=8.453 days. ...

Since there are a variety of machines on JANET, you are advised to check with your Computing Services as to how the file transfer software on the machine you are using works. In general, on Unix machines the transfer command will be hhcp or cpf . On VAX/VMS systems, the command is usually called transfer .
