Are there any space data service providers that focus on commercial remote sensing offerings for government users?

Yes. Several space data service providers sell commercial remote sensing products and services specifically to government users. A few well-known examples:

• Maxar Intelligence – High-resolution electro-optical satellite imagery, 3D data, and tasking services widely used by defense and civilian government agencies.
• Planet Labs – Large-scale Earth observation imagery and analytics for government monitoring, defense, disaster response, and mapping.
• BlackSky – High-cadence imagery and geospatial intelligence services geared toward government and national security customers.
• ICEYE – Synthetic aperture radar (SAR) imagery and monitoring services used by government users for all-weather, day/night surveillance.
• Capella Space – Commercial SAR imagery and analytics for defense, intelligence, and public-sector customers.
• Airbus Intelligence – Commercial satellite imagery and geospatial services sold to government and institutional users globally.
• Satellogic – Earth observation imagery and mapping products with government applications.
• Umbra – High-resolution SAR data and intelligence services, including government defense and security use cases.

If you want, I can also give you:
