Sorry for not keeping up; I hope I've not missed other messages in the past couple weeks. Have been trying to push the March VEX BSR data through our system and have left everything else on the back burner. If I don't reply within a day or so, you have something that needs an answer, and I've not said I'm traveling your best bet is to send another e-mail with a word like URGENT near the front of the Subject line -- or phone. It's my understanding that VEX has admitted that the S-Band transmitter on the prime transponder has failed - at least to the level that we can now explain the 15-18 dB carrier loss during the March experiments. But it's also my understanding that they have not made any decision to change the configuration for radio science experiments. For VEX BSR I would prefer to use the backup transponder, since we could then get a reasonable S-Band signal again. For occultations, however, the Europeans want to continue with the current configuration. VEX has a USO, so you should set up assuming the spacecraft will be transmitting one-way and on its prime transponder -- unless you receive a modified DKF which shows two-way. VEX is different from MEX in this way (in having a USO). The USO only works with the prime transponder; there is no cross-linking to allow it to feed the second transmitter. So this is a choice for frequency stability over S-Band power. There will be a weak S-Band signal, and it may be useful. Can you compute the frequency predicts with a Venus atmosphere model? These are DEEP occultations and there will be a LOT of frequency changes. I recommend that you go with 25 kHz on S-RCP and X-RCP (LCP should not be needed) if you have the atmospheric model; if not, I'm not sure what to suggest. I think the Europeans have been using 1 MHz because they can't tune their ground receiver (grim!). You should record the WHOLE occultation, not the ingress and egress separately. There may be signal between them. We had no trouble finding the S- and X-band carriers when we did the VEX BSR's in March. Assuming ESA stays with the prime transponder and USO, I see no reason that you couldn't script the pass. If you can't include the atmospheric effects in the Doppler, it might be worth having someone present to manually tune the receiver. But I don't have any software that would all me to make suggestions for real-time frequency offsets (FRO's). I'll cc Bernd, Riccardo, and Silvia; but there's probably not enough time for them to generate predicts and get them to you even if they have the tools. Give me a call if you have further questions. I'll be here until early evening (and generally have lunch at my desk).

Since this is our first VEX RS DKF, it uncovered this problem. The events appear to be correct and the proper input files were used. I have checked and SPS will not care that we have the events labeled as Mars vs Venus. Ricardo will ISA the problem and work to fix it in the both the short and long term. Ricardo, we can just edit the DKF next time and then in the long run we should probably have the SATF extract the body from the OPTG, rather than hard code the planet. Thanks and good occultation hunting!

Danny Kahan (who did a great job) and I acquired the data from the occultation last night at DSS-43 (Australia 70-m station) at X-band (RCP) only. The S-band was not received but this problem was pre-announced by the project at the beginning of the pass. We used the RSR open-loop receiver tuned to remove the Doppler effect. We were also hoping to model the atmosphere of Venus in the RSR tuning predicts but were not able - we will fix this for the next occultation. We successfully captured the signal in a 25 kHz bandwidth. The attached two plots show the time history of the frequency and power. We also recorded wider bandwidths as a back-up that we will eventually delete once we confirm the 25 kHz is sufficient to you.

We never had to use it before since we never did a Venus occultation since the new tool was developed. We do not need an atmosphere model for Mars, etc. So, as a first time use, we ran into a problem. It was my fault for not doing a complete test in advance this snuck on me too. We are now fixing it for the next observation.

Do we expect this for future occultations? I don't know the exact geometry; but a limb-track maneuver was executed. It is possible that we would see a weak signal through the entire occultation during future experiments.
