New Techniques of Deep-Space Spacecraft Measurements
The paper proposes new techniques to measure trajectories of deep-spacecraft, particularly: new technique to perform Doppler angular measurements of spacecraft (ΔR measurement), technique to define parameters of spacecraft motion simultaneously when implementing trajectory measurements and equipment to perform a new pattern of trajectory measurements. The new proposed technique may be employed for trajectory measurements of any spacecraft with an orbit (trajectory) altitude enabling simultaneous tracking of at least three spacecraft scattered in the sky and engaged in a measurement process. That is why it is advisable to employ the technique described above in designing new generations of TT&C. A technique which allows measure all parameters of a spacecraft motion simultaneously can mostly benefit trajectory measurements of lunar and interplanetary spacecraft The cost of developing and operating the system which utilizes proposed techniques of trajectory measurements is considerably lower if compared with the previously used.
