Scientific paper
A system for measuring the parameters of radio signals transmitted from the lander module of the Mars-6 deep space probe by means of the signal relaying to earth via an orbiting relay vehicle is described. Energy relationships relevant to relay performance are cited. Digital processing of the signal employed for measurements during the descent phase in the Martian atmosphere is described. The operation of the module-orbit-ground station link is described, results of power and frequency measurements are cited, and results of data analysis are presented in brief. Data on the relative velocities of descent module and orbiter are presented, along with refined local estimates of Martian atmosphere variables.
