InvalidArgError splicing SP3 files

Orekit Python Wrapper usage
1

Hi all, I am facing an issue about splicing several SP3 files. I wrote the following code

sp3_parser = SP3Parser()
sp3_file_list = [“./final_ephemeris/gps/igs22325.sp3”, “./final_ephemeris/gps/igs22326.sp3”]
sp3_set = set()
for item in sp3_file_list:
    sp3_set.add(sp3_parser.parse(DataSource(item)))
sp3_source = SP3.splice(sp3_set)

I am receiving the following error

orekit.InvalidArgsError: (<class ‘org.orekit.files.sp3.SP3’>, ‘splice’, {<SP3: org.orekit.files.sp3.SP3@25d93198>, <SP3: org.orekit.files.sp3.SP3@4110765e>})

Honestly, I do not understand what’s the problem. As far as I understood, the method splice requires either a java collection of SP3 or a python sequence of SP3 or a python set of SP3. I am using a python set. Could you please give an advice? Thank you.

Hi there,

are you using the jpype version of the Python wrapper?
Have you tried converting your set into a list?

Cheers,

Hi, I managed to solve it doing as follows

sp3_set = ArrayList().of_(SP3)
for item in sp3_file_list:
    sp3_set.add(sp3_parser.parse(DataSource(item)))
sp3_source = SP3.splice(sp3_set)

Thank you for your suggestion.
