I don't know what geospatial features are needed, but otherwise time series databases are great for this use case.

I especially like Clickhouse, it's generic but also a powerhouse that handles most things you throw at it, handles huge write volumes (with sufficient batching), supports horizontal scaling, and offloading long-term storage to S3 for much smaller disk requirements. The geo features in clickhouse are pretty basic, but it does have some builtin geo datatypes and functions for eg calculating the distance.
