Satcat LEOP Overview
Satcat LEOP provides structured support during the Launch and Early Orbit Phase (LEOP), helping operators maintain custody and situational awareness from deployment through commissioning. The service is designed to reduce tracking uncertainty and asset loss in the early days after launch, and assist cataloging efforts.
Why LEOP Support Is Necessary
LEOP is a time-constrained phase marked by limited data availability and elevated operational risk. Initial deployment data degrades within 72 hours post-launch, when telemetry pipelines may not be fully online. Without a structured custody solution in place, operators face increased likelihood of delayed commissioning or permanent asset loss.
Operators relying solely on initial deployment data sources may lose track of their asset if no ongoing custody plan is in place.
What Satcat LEOP Provides
Satcat LEOP extends early orbit visibility by:
- Delivering accurate initial state data with spaceweather corrections
- Ingesting and cataloging operator-provided ephemeris
- Supporting telemetry-based orbit determination (LEOP Pro)
- Coordinating external tracking and NEI response (LEOP Pro + Tracking)
Service coverage extends 30 days post-launch, with extension options available.
Service Tiers
Satcat LEOP is offered in three levels:
- LEOP Essentials: Deployment-data driven visibility and basic ephemeris support
- LEOP Pro: Adds telemetry ingestion and ongoing OD products (recommended)
- LEOP Pro + Tracking: Adds third-party tracking services and NEI coordination
Each tier corresponds to the level of custody assurance required. For most missions, LEOP Pro is the best solution.
