Overview

ISO 22772:2020 - Space systems: Requirements of launch vehicle (LV) to electrical ground support equipment (EGSE) interfaces - defines standardized electrical interface requirements between a launch vehicle and non‑flight electrical ground support equipment used for on‑line processing. The standard helps designers produce clear Interface Requirements Documents (IRD) and Interface Control Documents (ICD) to reduce miscommunication, lower design costs, and mitigate risk during launch preparation and operations.

Key Topics and Requirements

ISO 22772:2020 covers the full lifecycle of LV to EGSE interfaces with emphasis on clarity, safety and verification. Major technical topics include:

Interface types and implementations
- Bus interfaces (e.g., CAN, serial/fibre channel styles) - topology, medium, data rates, protocols, timeout handling
- Digital I/O - voltages, currents, timing, isolation (relays/opto‑couplers)
- Analog interfaces - signal ranges and conditioning
- AC/DC power supply interfaces - grounding, floating vs single/multi‑point configurations
- RF/electromagnetic considerations
Design principles
- Clear, unambiguous signal definitions
- Use of standard interfaces where possible
- Electrical matching between sources and loads
- Isolation, redundancy, extensibility and EMC (filtering, shielding, grounding)
- Preservation of manufacturer and safety margins
Induced environment
- Mechanical: low‑frequency vibration, random vibration, acoustic noise, shock
- Thermal: pre‑launch and launch phase temperature considerations
- Radio and electromagnetic environment: LV‑, EGSE‑ and range‑generated effects
Verification methods
- Analysis (feasibility, simulation) and test verification
- Launch‑preparation state evaluation
- Interface inspection and operational checks at the launch site
Documentation and operational checks
- IRD and ICD content requirements, interface inspection verification, combined operations and safety procedures

Applications and Who Uses It

ISO 22772:2020 is intended for:

Launch system designers and interface engineers defining LV‑EGSE connections
EGSE contractors and test engineers preparing ground equipment
Systems and integration teams responsible for ICD/IRD generation and verification
Launch site personnel conducting interface inspections and combined operations
Procurement and risk‑management teams seeking standardized interface specs to reduce integration errors

Practical applications include specifying data buses and power feeds, defining grounding/topology rules, planning EMI mitigation, and establishing test plans and acceptance criteria for LV‑EGSE integration.

Related Standards

ISO/IEC Directives (editorial and development procedures)
ISO/TR 16158 (interface control document terminology)
Relevant EMC and electrical safety standards (as applicable for implementation and verification)

ISO 22772:2020 supports consistent, verifiable LV to EGSE interface design to streamline integration and increase launch safety and reliability.
