ISO 14620-3 pdf download Space systems — Safety requirements — Part 3: Flight safety systems
1 Scope
This document sets out the minimum requirements for flight safety systems (FSSs), including flighttermination systems (FTSs, externally controlled systems or on-board automatic systems), trackingsystems, and telemetry data transmitting systems (TDTSs) for commercial or non-commercial launchactivities of orbital or suborbital, unmanned space vehicles. The intent is to minimize the risk of injuryor damage to persons, property or the environment resulting from the launching of space vehicles.
This document can be applied by any country,by any international organization,whetherintergovernmental or not, and by any agency or operator undertaking the launching of space vehicles.This document is intended to be applied by any person,organization,entity,operator or launchauthority participating in commercial or non-commercial launch activities of orbital, or suborbital,unmanned space vehicles unless more restrictive requirements are imposed by the launch site country.

flight safety system
combination of flight-, ground- or space-based hardware and software designed,installed and/oroperated specifically for providing flight safety
Note 1 to entry: This combination of equipment, facilities,procedures and personnel required to monitoroperations provides protection to personnel and property both foreign and domestic from any damage that canbe caused by a non-nominal flight.
Note 2 to entry: The flight safety system may include flight termination systems(3.2),telemetry data transmittingsystems (3.6) and range tracking systems (3.4].
flight termination system
explosive or other disabling or thrust-terminating equipment installed in a launch vehicle, plus anyassociated ground equipment, for terminating the flight of a malfunctioning vehicle or stage
initial action to place, or attempt to place, a launch vehicle and payload if any, in a suborbital trajectory,in Earth orbit in outer space, or otherwise in outer space
range tracking system
combination of flight-, ground- or space-based hardware and software designed, installed and/oroperated specifically for tracking a launch vehicle
safety envelope
area designated for launch (3.3) and preorbital flight that is cleared of uninvolved persons or where therisk of injury, fatality or property damage to the public is below a designated threshold probability (3.7)3.6
telemetry data transmitting system
combination of flight- or space-based hardware and software, designed, installed or operated for down-linking vehicle and flight system performance and health data to flight safety operators
threshold probability
probability that loss or damage will exceed a specified level
Note 1 to entry: Threshold probability is a quantitative measure that represents the probability of ocurrenceassociated with unplanned events or levels of damage caused by launch-related activities.
