1)Re error: Craig,you say that the received frequency power in
the FFT diagram is centered on the specific frequency of the local oscillator frequency that most closely matches in phase and frequency the received frequency. You say it is by eyeball estimation about 15 to 20db above the values at other frequencies. So, Craig, George, Is it unnecessary to reconcile this error estimate with the difference between the recieved oscillations of voltage and the oscillations produced by a local oscillator at a specifc rms amplitude at the selected frequency made to match most closely in phase the received oscillations and then modified in frequency to maintain the close match? Perhaps so. But what about the degree of correspondence of zero crossings in the selected in phase local oscillator sequence of oscillating voltages and the corresponding sequence of zero crossings in the reduced(intermediate)representation of the received frequency? I should think that this would be indicative of the reliability of the 'detected' frequency and phase given to the local oscillator and would have some relationship to the 100db Sig/Noise or whatever indicated FFT frequency with the most power.?? 2)Re transmitted frequency: For the nth time where is the transmitted frequency or is this just something you make up to give the predicted Doppler result assuming the speed of light delay? 3)Re received frequencies.In the tracking data logical record, item 31 and 32 gives Doppler Count in units of 1000 time the number of cycles. I gather this corresponds to Craig's Doppler count which is instead in units of cycles. What item gives the FSKY minus 2292000000Hz? 4)re p6 of DSN 810-005 Rev.E/202,Rev.A "The uplink carrier frequency is synthesized with the exciter ...... [at the receiver site] ...The uplink carrier may be either constant or varied in accord with a tuning plan. In either case, the phase of the[synthesized] uplink carrier is recorded for use in the computation of a Doppler effect." This sounds to me like the transmitted frequency at the assumed transmission site is simulated at the receiver site and used in computing the expected frequency. 5)Thus unless it is possible to determine the transmit frequency at the receiving site it will not be possible to test the hypothesis that light speed does not extrapolate beyond 1 second(ie beyond r for r/c1). If the transmit frequency at the receiving site is known to be the same as the transmit frequency at the assumed site then of course it would be possible to test this hypothesis. |
