The frequency is 8465 MHz and for the moment don’t have ephemeris from the JPL/Horizons or spice kernels. For the moment using the ephems from GBOT getting a aprox RA and DEC and using my own tools for full tracking.
Integrating the Yutu using baudline the signals recorded during the seperation from the Chang’e 3 you can see two signal variations. At the 20:27:31 UTC during two minutes aprox the signal was more weak and scince the 20:35:40 UTC the signal was boosted. Then the separation was before of the 20:40 UTC ?
Yesterday the Chang’e3 spacecraft andt the Yutu rover was landing successfuly. I was start to track the moon since the 18:30 to the 22:30 UTC. And I was listen Yutu from the start of my window and the signal was over 15dB of SN at 1Hz of BW. The frequency of the rover is 8462.08000MHz with the moon doppler of -0.6Hz/s of aprox. The signal was easy to listen in the earphones, and sounds like a some kind of morse.
The command line to use rtlsdr with baudline was:
rtl_fm -g 44 -d0 -f$1 -s 250000 -F -U | ./baudline.static -stdin -samplerate 250000 -channels 1 -session rtlsdr1chUSB0 -basefrequency $1
Now you can listen how sounds the data stream from Yutu. A short audio record of the signal demodulated:
Another full orbit of Chang’e 3 centered ar 8470MHz with a 100KHz span. This time with locking to ground station included:
Zoom of one of the frequency lock to some tracking Ground Station:
Yesterday the Chang’e3 spacecraft finished the orbital insertion into polar orbit around the moon. The signal is strong and easy to listen in the receiver speaker. Today I get a full orbit of the probe. Every pixel are 10secs and the receiver was tuned at 8479.749200MHz
