Weird error about orbit file

Hello guys
i was performing some SAR analysis but since last night i am getting this error

most of the processing is also generating similar error .

can anyone help me with this

thank you

the date (01-JAN-2000) indicates that the correct date was not readable from the metadata or has been lost during the proessing. What data are you using and which steps did you apply?

this is the data i am using

  1. S1A_IW_SLC__1SDV_20170326T233035_20170326T233102_015870_01A271_B8E8
  2. S1A_IW_SLC__1SDV_20161220T233038_20161220T233105_014470_0177A5_D8C4

and i got this error in the coregistration step

  1. S1A_IW_SLC__1SDV_20161102T233039_20161102T233106_013770_0161D0_6731

  2. S1A_IW_SLC__1SDV_20170326T233035_20170326T233102_015870_01A271_B8E8

its the above data i am using not the ones mentioned before

i am getting this error when i am performing Debursting

plz advice

I’m confused. You got the error about the orbit files during the coregistration process?

If you want to coregister 2 S1 SLC data sets you could use
Radar > Coregistration > S1 TOPS Coregistration > S1 TOPS Coregistration
instead of performing the steps manually. I am assuming this based on the file name _Orb_stack_ifg_deb.

Have you seen this manual?

yes i have performed the coregistration based on the manual.The second error which i mentioned above (i got it while performing Debursting ) is from different file

I also met this error yesterday. The solution: download the file again.
