Deep Space Network antennas send carrier signals without data for tracking purposes
Deep Space Network antennas utilize transmitted carrier signals to perform precise Doppler tracking and radio science observations of deep space spacecraft.
The retrieved papers consistently describe the use of carrier signals (without relying on high-rate telemetry data payloads) for precision Doppler tracking and navigation of deep space probes. Papers [0], [1], [2], and [4] all highlight how these carrier signals are tracked to compute velocity, time delay, and phase noise, directly supporting the claim.
