Abstract:

The range and range rate system in its very simplest form is described. In particular, the errors in position and velocity are treated using pessimistic values of the measured quantities range and range rate. Thus, a realistic evaluation of tracking qualities can be made for different orbits over certain tracking stations. The range and range rate system is a high precision tracking system. Knowledge of the uncertainty in position is important, but knowledge of the uncertainty of the velocity vector is of the utmost importance. Thus, the use of coherent doppler measurements to determine the velocity has a great advantage over any pulsed system and, in addition, permits extremely narrow frequency bands in the order of 10 to 100 c to be employed, reducing the power requirements considerably.
