Split SDR data
Posted: Wed Feb 15, 2017 5:28 am
Hello,
we use CSPP_SDR_V2.2.3 including leap second update from Dec 2016 that is embedded in MEOS Polar software (Kongsberg Spacetec).
From time to time, we see that the SDR data from a single pass are split into 2 files with consecutive timestamps, e.g.:
SVI01_npp_d20170214_t1027397_e1031550_b27468_c20170214161229073365_cspp_dev.h5
SVI01_npp_d20170214_t1031562_e1040274_b27468_c20170214161231013416_cspp_dev.h5
.

GITCO_npp_d20170214_t1027397_e1031550_b27468_c20170214161041172982_cspp_dev.h5
GITCO_npp_d20170214_t1031562_e1040274_b27468_c20170214161046565861_cspp_dev.h5
though there is just one input RDR file from the pass. Our RDR files are produced by the DRL RT-STPS software v5.6. I tried to use also the RDR files from the latest version v5.9 but result was the same.
Could there be some problem with granules aggregation or something similar? Or is it normal to have the data split like this?
We would like to solve the problem also because the doubled files cause the software crashes due to memory overflow and so we lose some of the data.
If it can be of any help, I attached the MEOS Polar log file including outputs from the CSPP SDR software.
Thanks.
