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 2015 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 8th OCEL-session is on 1/2 December 2015 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 December 1, UT 23:00-23:30 December 2, UT 05:00-05:30 December 2, UT 11:00-11:30 The station network consists of 10 stations: Badary, Fortaleza, Hart15m, Hobart26, Kokee, Matera, Nyales20, Onsala60, TianMa64, Wettzell, Zelenchukskaya. 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 normal R1-session frequency setup with 8 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 modified to 4 MHz only. On demand by the Bonn correlator, phase-cal is switched off. However, stations that can set physical on and off by software are welcome to switch phasecal on for setup01 (geodetic observations). There are in total 22 phase-referencing (PR) intervals: RD.15.10 / OCEL-08, phase referencing with 7 sources: ----------------------------------------------------- 0928+144 0932+094 0943+105 1005+066 1013+054 1013+127 1015+057 Observation listing from file /home/mk5_2014/sched/ocel08.skd for experiment RD1510 Source Start DURATIONS --------------------------------------------------------------- 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 rd1510_bd.vex rd1510_ft.vex rd1510_ht.vex rd1510_ho.vex rd1510_kk.vex rd1510_ma.vex rd1510_ny.vex rd1510_on.vex rd1510_wz.vex rd1510_zc.vex The stations should use their individual vex file, copy it to the name rd1510.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 warnings 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 usually used for wide-band R1-sessions, 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 : 8994.00 MHz : U : 4.000 MHz : &CH09 : &BBC08 : &U_cal; chan_def = &X : 8994.00 MHz : L : 4.000 MHz : &CH10 : &BBC08 : &U_cal; *--------------------------------------------------------------------------* To avoid potential problems in the correlation with the lunar lander frequencies, phasecal is switched off. However, stations that can set phasecal on and off by software are welcome to switch phasecal on for setup01 (geodetic observations). An approximate summary of the session is given below. The amount of data to be recorded is just 1.3 TB or less per station. The stations should transfer (e- or ship) the data to the Bonn correlator after the session is done.
