Status of Delta-DOR Cross-Support Activities at JPL James S. Border Jet Propulsion Laboratory 2017 CCSDS Spring Meeting San Antonio, Texas, May 10-12, 2017
Jet Propulsion Laboratory California Institute of Technology Current Cross-Support Activity DDOR cross-support continues for Hayabusa-2 A few passes completed in 2017 More passes planned for 2018-2020 Requested support overlaps with DSN contention periods for Mar missions in 2018 and 2020 JPL is nearing completion of ISRO MOM DDOR cross-support Zodiac/Cortex open loop receiver has worked well at Bangalore 32m DSN will likely provide DDOR cross-support for several missions in the 2020 Mars opportunity window 2 CCSDS Meeting, San Antonio, Texas, May 10-12, 2017
Jet Propulsion Laboratory California Institute of Technology Open Loop Receiver Upgrades at JPL-1 New OLR implementation in progress Part of the all-digital DSN “Common Platform” RF sub-band downconverted and digitized • X-band is 8200-8600 MHz • Ka-band is 31800-32300 MHz Same digital IF is fed to both closed-loop and open-loop processors Each OLR can accept data from up to 16 frequency channels • Each frequency channel can be from either same or different RF Higher open loop data recording rate is possible • 512 Mbit/s or higher Planned operational date: January 2018 3 CCSDS Meeting, San Antonio, Texas, May 10-12, 2017
Jet Propulsion Laboratory California Institute of Technology Open Loop Receiver Upgrades at JPL-2 Native data recording format to be RDEF DDOR SW will be updated to directly process RDEF Testing will be possible Concurrent recording on WVSR and OLR Data translation between VDR and RDEF OLR will be available to support Bepi PN ranging at 24 Mcps SW is being developed to process PN T2B ranging from WVSR/OLR recordings JPL is planning to support high chip rate PN ranging only with open loop recordings Low chip rates (e.g. 3 Mcps) can also be supported by closed loop processing 4 CCSDS Meeting, San Antonio, Texas, May 10-12, 2017
