Описание (английский):

This document describes a process for the long-duration orbit lifetime prediction of orbit lifetime for spacecraft, launch vehicles, upper stages and associated debris in LEO-crossing orbits after mission phase (including any mission lifetime extensions). The document also clarifies: a) modelling approaches and resources for solar and geomagnetic activity modelling; b) resources for atmosphere model selection; c) approaches for spacecraft ballistic coefficient estimation.

Overview

ISO 27852:2024 - "Space systems - Estimation of orbit lifetime" (3rd edition) provides a consensus-based process for long-duration orbit lifetime prediction of spacecraft, launch vehicle stages and associated debris in LEO-crossing orbits (perigee ≤ 2 000 km). Updated in 2024, this standard replaces the 2016 edition and clarifies modelling approaches for solar and geomagnetic activity, atmosphere model selection, and spacecraft ballistic coefficient estimation. It is intended to support compliance with space debris mitigation requirements (notably ISO 24113) and to harmonize with IADC and United Nations guidance.

Key Topics

Scope & definitions: Lays out terms such as orbit lifetime, end of mission, disposal phase and protected regions; defines long-duration predictions spanning multiple solar cycles (e.g., 25-year lifetime).

Orbit lifetime methods:

Method 1: high-precision numerical integration (detailed propagation).
Method 2: rapid semi-analytical orbit propagation.
Method 3: numerical table look-up, fitted equation evaluations and statistical approaches for high-eccentricity orbits (e.g., GTO).

Atmospheric density & solar forcing:

Selection and use of atmospheric drag models and thermospheric considerations (including global cooling implications).
Approaches for solar and geomagnetic activity modelling: Monte Carlo random-draw, predicted solar activity profiles, equivalent constant indices, and reference solar forcing scenarios (multiple methods explained).
Reference to solar flux metrics (e.g., F10.7) and incorporation of recommended datasets (including alignment with CMIP6 forcing where appropriate).

Ballistic coefficient (β) estimation:

Methods to estimate aerodynamic and solar radiation pressure coefficients (panel models).
Adjustments for rarefied gas flow (Knudsen number) and treatments for tumbling vs stabilized configurations.
Mass and cross-sectional area estimation guidance.

Supplementary material: informative annexes on space population distribution, example 25-year predictions, and treatment of solar radiation pressure and 3rd-body perturbations.

Applications

ISO 27852 is practical for:

Satellite designers and mission planners performing end-of-life and disposal analysis.

Launch providers and operators assessing post-mission orbital decay of upper stages.

Spacecraft operators demonstrating conformity with debris mitigation requirements (e.g., ISO 24113).

Regulatory agencies and orbital debris analysts conducting risk assessments, licensing reviews, and long-term population modeling.

Researchers and tool developers building orbit lifetime prediction software, atmospheric model selection tools, or ballistic coefficient estimators.
