This document addresses the essential elements and protocols needed for Space Traffic Coordination (henceforth referred to as “STC”). STC is critical to enhance the safety, stability, and sustainability of operations in the space environment.” STC enables flight safety, mitigates collision risk (for manoeuvrable spacecraft), and mitigates Radio Frequency Interference (RFI) for all phases of flight, spanning pre-launch safety assessment through manoeuvre plans, on-orbit collision avoidance, RFI mitigation support services, and mission disposal. This document is designed to enable the effective coordination of space traffic from pre-launch safety assessment to disposal at the end of operation through norms, the effective monitoring, and mitigation of collision risk and RFI. The document is designed for state actors, spacecraft designers, spacecraft operators, and STC system developers and operators. While this document applies to the range of orbital regions in which current STC and SSA systems can effectively track, monitor, and provide actionable data for space objects, it is envisioned that this document is generally applicable to all orbit regimes and for orbits around all central bodies and barycentres.

This document concerns human exposure to whole-body vibration and shock in buildings with respect to the comfort and annoyance of the occupants based on both measurements and simulations. It specifies a method for measurement and evaluation, comprising the determination of the measurement direction and measurement location. It defines in Annex A the frequency weighting Wm which is applicable in the frequency range 1 Hz to 80 Hz where the posture of an occupant does not need to be defined. Whilst it is often the case that a building will be available for experimental investigation, many of the concepts contained within this document would apply equally to a building in the design process or where it will not be possible to gain access to an existing building. In these cases, reliance will have to be placed on the prediction of the building response by some means. This document does not provide guidance on the likelihood of structural damage, which is discussed in ISO 4866[3]. Further, it is not applicable to the evaluation of effects on human health and safety. Acceptable magnitudes of vibration are not stated in this document, but guidance is provided in Annex C in the form of exposure-response curves for the estimation of annoyance when vibration originates from various sources, including railway, construction activities and blasting.
