Thomas" Ed Himwich UBonn: Axel Nothnagel Alessandra Bertarini Laura la Porta BAAC: Tang Geshi IVS: ivs-stations@ivscc.gsfc.nasa.gov -------------- a) Background: -------------- Tang Geshi and several co-PIs proposed in May 2014 to observe the Chinese Lunar Lander Chang'E-3 with VLBI. This proposal was accepted by the IVS PC and a series of RD-sessions was allocated for this purpose. In 2016 there will be 4 of this type of sessions. The scheduling is done by R. Haas (Chalmers University of Technology, Sweden), the Lunar Lander apriori positions are provided by Tang Geshi (BAAC, China), the primary correlation will be done by the Bonn correlator and special correlation issues will be looked into by the correlators at BAAC (China) and Onsala (Sweden). The data will be analyzed by the proposing consortium (PIs), and the data have a one year data hold after successful correlation. ------------ b) Schedule: ------------ The 10th OCEL-session is on 18/19 May 2016 when the Chang'E-3 lander will be actively sending on several X-band channels, among them a data channel and several DOR tones. The five DOR tones are at the following frequencies: 8450.75 MHz 8466.15 MHz 8470.00 MHz 8473.85 MHz 8489.25 MHz There will be no DOR tones sent: May 18, UT 23:00-23:30 May 19, UT 05:00-05:30 May 19, UT 11:00-11:30 The station network consists of 12 stations: Badary, Fortaleza, HartRAO, Hobart26, Kokee, Medicina, Nyales20, Onsala60, Seshan25, Urumqi, Wettzell, Zelenchukskaya. -Onsala is not listed in the IVS master schedule as a participating station, but can join for for more than 12 hours (17:30 UT on May 18 to 06:00 UT on May 19). So it was added as tagalong station for 12 hours. - Kokee is also added as tagalong station, since it is not sure that they will be ready to observe after the maintenance. We will see Since it was/is unclear whether Kokee will participate or not, there are no Lunar Lander observations planned for the time UT 02 to UT 09 when the Moon is up over the Pacific. Kokee would have been essential for having any Lunar Lander observations in this period. - Ny-lesund can unfortunately not see the Moon at all during this session, so it is entirely doing normal geodetic observations. The schedule is basically alternating between standard geodetic observations and lunar lander observations with some kind of phase-referencing attempt. The stations not participating in the phase-referencing, since they do not see the moon, will do standard geodetic observations during this time. For the standard geodetic observations we use a standard GEOSX frequency setup with 4 MHz bandwidth. For the lunar lander observations the X-band frequencies are changed to be able to receive the DOR (and communication) signals, and the bandwidth is kept at 4 MHz. Phase-cal shall be on though the session. There are in total 16 phase-referencing (PR) intervals: RD.16.04 / OCEL-10, phase referencing with 6 sources: ----------------------------------------------------- 1329-049 1333-082 1334-127 1351-018 1352-104 1403-085 Observation listing from file /home/mk5_2014/sched/ocel10.vex for experiment RD1604 +---------------------------------------------------------------------+ Phase referencing PR-01 -

The files are individual per station since the lunar lander has slightly different apriori ra/dec coordinates as seen from the different participating stations, since the Moon is in the near field. The vex files are rd1641_bd.vex rd1604_ft.vex rd1604_hh.vex rd1604_ho.vex rd1604_kk.vex rd1604_mc.vex rd1604_ny.vex rd1604_on.vex rd1604_sh.vex rd1604_ur.vex rd1604_wz.vex rd1604_zc.vex The stations should use their individual vex file, copy it to the name rd1604.vex and then drudg it in order to produce snap-file and procedure-file. The FS version 9.11.6 or higher appears necessary. There might though be some warning messages by drudg, however, the resulting snp and prc-files should be correct and working. There are three setups in the session, setup01, setup02 and setup03. The first setup is a standard setup, while the second setup and third setups are special lunar lander setups. For the latter two, the X-band frequencies are modified in order to correspond to the lunar lander sending frequencies. There are setup02 and setup03 in order to make it possible for stations that do not have automatic gain control, to use special and individual attenuation when observing the lunar lander and natural radio sources in phase-referencing mode. All lunar lander center frequencies are between 8450 MHz and 8496 MH, with bandwidth of 2 to 5 MHz. The data channel with center frequency 8496 MHz is rather strong with an EIRP of about 16 W. The DOR channels are located at 8470 MHz and tones at +/- 19.2 MHz and +/- 3.85 MHz and these channels have an EIRP of about 1 W. Due to the rather strong signals, the received signal strength is on the order of 10-30 dB stronger than normal natural radio sources. Thus, additional attenuation might be implemented in the lunar lander setup. Stations with Mark4 racks should prepare to add on the order of 10-30 dB, and then monitor and adapt the attenuation correspondingly. This can be done in the beginning of the experiment when the first observations of the lunar lander signals are performed. Only X-band BBC 3 to BBC 8 are used for the lunar lander observations. The X-band frequency distribution is as follows: *--------------------------------------------------------------------------* chan_def = &X : 8212.99 MHz : U : 4.000 MHz : &CH01 : &BBC01 : &U_cal; chan_def = &X : 8212.99 MHz : L : 4.000 MHz : &CH02 : &BBC01 : &U_cal; chan_def = &X : 8252.99 MHz : U : 4.000 MHz : &CH03 : &BBC02 : &U_cal; *--- aiming at Lunar Lander DOR tones -------------------------------------* chan_def = &X : 8448.75 MHz : U : 4.000 MHz : &CH04 : &BBC03 : &U_cal; chan_def = &X : 8464.15 MHz : U : 4.000 MHz : &CH05 : &BBC04 : &U_cal; chan_def = &X : 8468.00 MHz : U : 4.000 MHz : &CH06 : &BBC05 : &U_cal; chan_def = &X : 8471.85 MHz : U : 4.000 MHz : &CH07 : &BBC06 : &U_cal; chan_def = &X : 8487.25 MHz : U : 4.000 MHz : &CH08 : &BBC07 : &U_cal; chan_def = &X : 8491.10 MHz : U : 4.000 MHz : &CH09 : &BBC08 : &U_cal; chan_def = &X : 8491.10 MHz : L : 4.000 MHz : &CH10 : &BBC08 : &U_cal; *--------------------------------------------------------------------------* Phasecal shall be switched on for all three modes. An approximate summary of the session is given below. The amount of data to be recorded is just 0.6 TB or less per station. The stations should transfer (e- or ship) the data to the Bonn correlator after the session is done.
