Sentinel-1 time series: how selecting orbit number

openEO Platform
1

Hello everyone,

I am new to this forum and excited to engage with the community here. My current work involves analyzing time series data from Sentinel-1 satellites, with a focus on implementing my REACTIV change detection algorithm within the OPENEO platform.

I have a question regarding selecting specific orbit numbers to create a time series from the same orbital tube. Currently, I can filter the collection by ascending orbits using the following code snippet:
python

s1_cube = connection.load_collection(
    "SENTINEL1_GRD",
    temporal_extent=("2019-06-01", "2020-01-01"),
    spatial_extent=bbox_aoi,
    bands=['VH', 'VV'],
    properties=[
        openeo.collection_property("sat:orbit_state") == "ASCENDING",
    ],
)

However, I am looking for a way to select images based on a specific orbit number, and I haven’t found the appropriate property. Does anyone have experience with this or could guide how to filter by orbit number within OPENEO?

Thank you in advance for your assistance!
