Fourier transform or Walsh transform).
"Software" (GSN All) means a collection of one or more "programs" or "microprograms" fixed in any tangible medium of expression.
"Source code" (or source language) (4 6 7 9) is a convenient expression of one or more processes which may be turned by a programming system into equipment executable form ("object code" (or object language)).
"Spacecraft" (7 9 ML11) means active and passive satellites and space probes.
"Spacecraft bus" (9) is equipment that provides the support infrastructure of the "spacecraft" and location for the "spacecraft payload".
"Spacecraft payload" (9) is equipment, attached to the "spacecraft bus", designed to perform a mission in space (e.g., communications, observation, science).
"Space‑qualified" (3 6 7 9 ML19) refers to products designed, manufactured, or qualified through successful testing, for operation at altitudes greater than 100 km above the surface of the Earth.
Note: A determination that a specific item is "space‑qualified" by virtue of testing does not mean that other items in the same production run or model series are "space‑qualified" if not individually tested.
"Special fissile material" (0) means plutonium‑239, uranium‑233, "uranium enriched in the isotopes 235 or 233", and any material containing the foregoing.
"Specific modulus" (0 1 9) is Young's modulus in pascals, equivalent to N/m2 divided by specific weight in N/m3, measured at a temperature of (296 ± 2) K ((23 ± 2)oC) and a relative humidity of (50 ± 5)%.
"Specific tensile strength" (0 1 9) is ultimate tensile strength in pascals, equivalent to N/m2 divided by specific weight in N/m3, measured at a temperature of (296 ± 2) K ((23 ± 2)oC) and a relative humidity of (50 ± 5)%.
"Spinning mass gyros" (7) "Spinning mass gyros" are gyros which use a continually rotating mass to sense angular motion.
"Spread spectrum" (5) means the technique whereby energy in a relatively narrow‑band communication channel is spread over a much wider energy spectrum.
"Spread spectrum" radar (6) — see "Radar spread spectrum".
"Stability" (7) means the standard deviation (1 sigma) of the variation of a particular parameter from its calibrated value measured under stable temperature conditions. This can be expressed as a function of time.
Technical Note:
For gyroscopes and accelerometers, "stability" can be estimated by determining the Allan variance noise‑analysis value at the integration period (i.e., sample time) consistent with the stated measurement period, which may include extrapolating the Allan variance noise analysis beyond the instability point into the rate/acceleration random walk or rate/acceleration ramp regions to an integration period consistent with the stated measurement period (Reference: IEEE Std 952‑1997 [R2008] or IEEE Std 1293‑1998 [R2008]).
"States not Party to the Chemical Weapon Convention" (1) are those states for which the Convention on the Prohibition
