  • 5. <ul><li>User Data Request/Deliver Scheme. </li></ul><ul><li>A ll the CHRIS requests are sent to RSAC which elaborates then a consolidated planning for the use of the instrument taking into account the target visibility and the clouds prediction. </li></ul><ul><li>The HRC requests are collected by Redu which is in charge to interleave them in the CHRIS planning. The HRC requests can benefit from the RSAC clouds prediction data. </li></ul><ul><li>The technology experiments requests are issued from TOS-ES to Redu which is in charge of the implementation. </li></ul><ul><li>The Kiruna Esrange downlink data acquisition and the ESRIN Earthnet Product Archiving are under implementation . In order to increase the data return, it is foreseen to add 5 Kiruna downlink passes, 2 morning passes before the Redu passes and 3 evening passes before the Redu passes. </li></ul><ul><li>All the raw data products are made available automatically on the Redu server. The processing of the HRC pictures is done at Redu and the pictures are available on the server. A quick look tool is installed at Redu to process the CHRIS pictures and made them available on the server. </li></ul><ul><li>Sira mirrors via Internet the CHRIS raw data from Redu, processes them up to the Level 1 and make them available to the scientists on a ftp server. </li></ul>
  • 6. <ul><li>CHRIS operations description. </li></ul><ul><li>The CHRIS acquisition plan is published on the CHRIS website. The site selected by RSAC, according to visibility, priority and clouds prediction, is communicated to Sira by email (and/or telephone). The information is also available on the CHRIS website. </li></ul><ul><li>  Sira elaborates the CHRIS request accordingly via an UPLOAD form. The form and the instrument configuration files are automatically processed at Redu leading to the generation of the request telecommand procedure including the scheduling of the pictures downlink over the ground station. </li></ul><ul><li>CHRIS mission operations constraints. </li></ul><ul><li>PPU imaging cannot be performed simultaneously with pictures dump. </li></ul><ul><li>The HRC operations need the knowledge of the PPU switch-on time, which is dependant on the last CHRIS session. </li></ul><ul><li>A dump of 80 MB (5 x 240 sec. Dump) of CHRIS data requires a mean number of 2.5 passes therefore two targets must be separated by 3 passes. </li></ul><ul><li>The PROBA mission control system is attended only during normal working hours. The planning and scheduling activities with the preparation of the pass template are then done in the morning while the telecommands uplink can be spread over several passes like the data download. </li></ul>
  • 7. <ul><li>CHRIS requests and planning </li></ul><ul><li>RSAC is in charge of the planning of all the CHRIS requests including PI requests, EduPROBA, ESA Education Office and ESTEC TOS-ES. Priority is given according to the request type and the clouds prediction. </li></ul><ul><li>The number of CHRIS calibration is limited to 1 dark and 1 Sun per month. </li></ul><ul><li>Before 09h30 local Redu time and for each Redu normal working day, Sira communicates to Redu via telephone and email the CHRIS planning (target and time are enough) of the next working day (morning and evening passes) including the weekend and the Redu bank holidays. </li></ul><ul><li>As soon as a CHRIS request is made operational, an email is automatically sent to Sira (optional). </li></ul>
  • 8. <ul><li>CHRIS data processing </li></ul><ul><li>Sira generates quicklook data within one working day from acquisition and make them available on the server. </li></ul><ul><li>For operations purpose, Redu generates quicklook data using a ESTEC provided tool within one working day from acquisition and make them available on the server. </li></ul><ul><li>Sira generates L1 products in HDF format within 14 working days from acquisition and make them available on the ftp server. </li></ul><ul><li>The CHRIS temperature data and other telemetry data are made available on the Redu server within one working day from acquisition. </li></ul><ul><li>All the CHRIS requests uploaded to the satellite are logged in a catalog. </li></ul>
  • 9. <ul><li>HRC operations description </li></ul><ul><li>HRC operations are performed at Redu. According to the User Data Request/Delivery Scheme (see above), it has been identified that the HRC requests should come from EduPROBA, ESA Education Office, TOS-ES and RSAC. The request forms completed are processed by the target visibility planning software based on ESOC Flight Dynamics tool. The selection of potential sites can then be checked with the clouds prediction file provided by RSAC and the telecommand procedure including the schedule of the pictures dump inserted in the pass template. </li></ul><ul><li>After the processing which requires human intervention, the good pictures are made available on the Redu server </li></ul>
  • 10. <ul><li>HRC operations constraints </li></ul><ul><li>PPU imaging cannot be performed simultaneously with pictures dump. </li></ul><ul><li>The HRC operations need the knowledge of the PPU switch-on time. This one is dependant on the last CHRIS session. The HRC operations are interleaved with the CHRIS target and pictures dump times. </li></ul><ul><li>Only one target can be taken on the sunlit part of the orbit. </li></ul><ul><li>The MMU can hold a maximum of 5 HRC before overwriting. </li></ul><ul><li>CHRIS target takes priority over HRC target when both times coincide. </li></ul><ul><li>HRC requests and planning </li></ul><ul><li>The approach which has been chosen is to establish a list of potential targets and to try to take them at the best opportunities </li></ul><ul><li>HRC data processing </li></ul><ul><li>After the processing which requires human intervention, the good pictures are made available on the Redu server </li></ul><ul><li>All the HRC requests uploaded to the satellite are logged in a catalog. </li></ul><ul><li>  </li></ul>
  • 11. <ul><li>Technology experiments request </li></ul><ul><li>ESTEC PROBA Project Team initiates the Technology experiments requests and coordinates them with Redu. </li></ul><ul><li>Technology experiments list </li></ul><ul><li>The Technology experiments include the following: </li></ul><ul><li>Off earth observations and non baseline manoeuvres </li></ul><ul><li>SREM specific measurements (rotations) </li></ul><ul><li>GPS attitude </li></ul><ul><li>AST tests </li></ul><ul><li>MRM/SIPS testing </li></ul><ul><li>PASS test </li></ul><ul><li>Solar arrays efficiencies and albedo determination </li></ul><ul><li>Battery pseudo-cycling </li></ul><ul><li>Autonomous orbit determination without GPS </li></ul>
  • 12. <ul><li>Kiruna ESRANGE downlink capability </li></ul><ul><li>Under implementation. </li></ul><ul><li>Combined Kiruna/Redu pass planning for the next 10 days sent by Redu to Kiruna. </li></ul><ul><li>Kiruna cannot modify the first five days (TBC) of the planning. The remaining days can be updated with pass cancellation or re-scheduling. </li></ul><ul><li>The updated planning is sent then also to RSAC and made available on the Redu PROBA server. </li></ul><ul><li>Kiruna will be able to extract the PPU data (VC1)from the baseband equipement and make them vailable on a internet server for Sira download. </li></ul><ul><li>Quiclook pictures will also be generated at ESRANGE and downloaded to Redu. </li></ul>
