Abstract THIS IS THE C1XS DATA FROM THE CHANDRAYAAN-1 MISSION NORMAL PHASE.
Description ESSENTIAL READING = The DOCUMENT directory contains 3 instrument specific documents, these are the Experimenter to Archive Interface Control Document (EAICD) which details the structure of this PDS dataset and the various data types produced. The data handling ICD gives more details of the telemetry packets received from C1XS and the command packet format. The final document is the flight operations manual which gives the normal operating command sequences. The user is advised to refer to the papers published about the instrument, specifically Grande_et_al_2009_1, Crawford_et_al_2009_1 and Howe_et_al_2009_1.

Mission Description Mission Overview Chandrayaan-1, the first Indian mission to Moon, was designed to carry out high resolution remote sensing studies of the Moon to further our understanding about its origin and evolution. Chandrayaan-1 was launched on October 22, 2008 by PSLV-C11 at 00:52 UT from SDSC, SHAR. The lift-off and dry mass break-up is as follows: Lift-off mass : 1380 kg Dry mass : 560 kg Propellant mass : 818.2 kg Pressurant mass : 2.84 kg The launch of the spacecraft was planned such that the Moon is at one of its nodes when the Spacecraft arrives there. In order to have multiple launch opportunities every month and to contain burn errors, the phasing loop strategy with multiple loops and five Earth bound maneuvers is adopted. The injection parameters are as follows: Semimajor axis : 17971.73 km Eccentricity : 0.63094 Inclination : 17.9112 deg Perigee height : 254.457 km Apogee height : 22932.741 km The details of five Earth bound manuevers, lunar insertion manuever and circularization manuevers are given below: .-------------------------------------------------------------------------------------. | BURN | CENTRAL BODY | Perigee No | deltaV(m/s) | Dur (S) | Post Manuever orbit | | | | | | | prg X apg (km) | .--------|--------------|-------------|-----------------------------------------------. | | | | | | | | EBN #1 | Earth | 4 | 344.43 | | 299.2 X 37908.1 | | | | | | | | | EBN #2 | Earth | 8 | 328.14 | 912.36 | 336.3 X 74715.6 | | | | | | | | | EBN #3 | Earth | 9 | 221.69 | 567.73 | 347.8 X 165015.1 | | | | | | | | | EBN #4 | Earth | 10 | 77.17 | 192.18 | 459.4 X 266612.9 | | | | | | | | | EBN #5 | Earth | 11 | 60.70 | 147.68 | 972.8 X 379859.2 | | | | | | | | | TCM | Earth | | 0.82 | 5.59 | 802.8 X 378499.2 | .--------|--------------|-------------|-----------------------------------------------. | | | | | | | | LOI | Moon | - | 366.96 | 817.07 | 507.9 X 7510.1 | | | | | | | | | LBN #1 | Moon | - | 26.60...
