Launch Services
ISPTech provides upper-stage and payload-separation propulsion for launch service providers — vibration-qualified for the launch environment, with full handling documentation and schedule reliability to integrate into vehicle integration timelines.
Launch Services Propulsion Requirements
Launch Environment Constraints
Launch vehicle integration imposes extreme constraints on propulsion hardware. Vibration environments during ascent require qualification evidence across the full frequency spectrum. Propellant handling restrictions dictate loading sequences. Integration timelines demand hardware delivery to schedule.
- Vibration qualification: random vibration 14–22 Grms depending on vehicle class
- Shock qualification: 1,000–3,000 g terminal sawtooth across 100–10,000 Hz
- Propellant handling: pre-loaded or pad-fuelled options, facility authorisation dependent
- Integration schedule: hardware delivery 90–120 days before launch window
Qualification-Ready, Schedule-Committed
ISPTech propulsion products include dedicated environmental qualification data packages — vibration, shock, thermal cycle, and EMC — aligned to ECSS-E-ST-10-03 environmental standard. Documentation packages are structured to flow directly into launch vehicle compliance matrices.
- Environmental qualification data to ECSS-E-ST-10-03
- Vibration, shock, and thermal cycle test reports as standard
- Hazardous materials documentation: SDS, containment procedures
- Integration Interface Control Documents (ICDs) for all standard interfaces
