1. A system comprising:

  • a calibration system communicatively coupled with a spacecraft, the calibration system configured to;

    transmit an orthogonal frequency division multiplexed (OFDM) calibration signal to a satellite communications network of the spacecraft, the calibration signal including a first plurality of sub-carrier signals;

    receive from the spacecraft an OFDM receive calibration signal-including a second plurality of sub-carrier signals;

    determine a first set of differences between the first plurality of sub-carrier signals and the second plurality of sub-carrier signals; and

    use the determined first set of differences to adjust one or more transmission properties of the spacecraft.
