Abstract This is a Rosetta Radio Science data set, collected during the ROSETTA EXTENSION 3 phase 2016-07-01 to 2016-09-30. It is a Global Gravity measurement at the comet 67P and covers the time 2016-07-12T03:56:20.000 to 2016-07-12T13:42:01.500.
Description Data Set Overview The Rosetta (RO) Radio Science (RSI) Data Archive is a time-ordered collection of raw and partially processed data collected during the Rosetta Mission to Churymov-Gerasimenko. For more information on the investigations see the RSI User Manual [RSIUSERMANUAL2004] in the DOCUMENT/RSI_DOC folder. This is a Global Gravity measurement covering the time 2016-07-12T03:56:20.000 to 2016-07-12T13:42:01.500. This data set was collected during the Rosetta Extension 3 Phase (EXT3). For more information about RSI measurements see INST.CAT or the RSI User Manual [RSIUSERMANUAL2004]. Mission Phase Definition Mission phase abbreviations are defined in CATALOG/MISSION.CAT and DOCUMENT/ESA_DOC/RO_EST_TN_3372.PDF. General description of radio science data = Closed-loop and Open-loop data: There are in principle two different ways to record radio science data: Open-loop and closed-loop data. The CLOSED-LOOP system used a phase-lock loop in the receiver to track the downlink signal, reporting both amplitude and fre- quency at rates typically of 1-10 times per second. In the OPEN-LOOP system, the signal was simply converted to a baseband frequency range; the entire passband was sampled and recorded for later processing. Typical open-loop sampling rates for ROS were 2000 complex samples per second. CLOSED-LOOP data are efficient for characterizing slowly changing signals; OPEN-LOOP data (because of their much higher volume) are usually used when the signal is very dynamic - such as during an occultation or bistatic radar measurement. The data set includes four primary data types with respect to the two different ground station systems. These systems are on the one hand the ESA ground station in New Norcia, Australia (NNO) and the NASA Deep Space Network (DSN). CLOSED-LOOP data types: | |- ESA: Intermediate F...

The spacecraft carries a Rosetta Lander, named Philae, to the nucleus and deploys it onto its surface. A brief description of the mission and its objectives can be found in [GLASSMEIERETAL2007A]. A detailed description of the mission analysis can be found in the ROSETTA User Manual [RO-DSS-MA-1001], and the flight Operations Plan [RO-ESC-PL-5000]. On its long way to the comet nucleus after a Launch by Ariane 5 P1+ in March 2004, the ROSETTA spacecraft orbited the Sun ...
