sensors are considered 'geographically dispersed' when each location is distant from any other more than 1,500 m in any direction. Mobile sensors are always considered 'geographically dispersed'.
N.B.: See also Munitions List controls.
                Note: 6A008.l. does not apply to systems, equipment and assemblies designed  for 'vessel traffic services'.
Technical Notes:
           1. For the purposes of 6A008., 'marine radar' is a radar that is designed to navigate safely at sea, inland waterways or near‑shore environments.
           2. For the purposes of 6A008., 'vessel traffic service' is a vessel traffic monitoring and control service similar to air traffic control for "aircraft".
6. A. 102. Radiation hardened 'detectors', other than those specified by 6A002, specially designed or modified for protecting against nuclear effects (e.g. electromagnetic pulse (EMP), X‑rays, combined blast and thermal effects) and usable for "missiles", designed or rated to withstand radiation levels which meet or exceed a total irradiation dose of 5 x 105 rads (silicon).
Technical Note:
In 6A102, a 'detector' is defined as a mechanical, electrical, optical or chemical device that automatically identifies and records, or registers a stimulus such as an environmental change in pressure or temperature, an electrical or electromagnetic signal or radiation from a radioactive material. This includes devices that sense by one time operation or failure.
6. A. 107. Gravity meters (gravimeters) or gravity gradiometers, usable in "missiles", and components for gravity meters and gravity gradiometers, as follows:
a. Gravity meters, other than those specified by 6A007.b, designed or modified for airborne or marine use, and having all of the following characteristics:
1. A static or operational accuracy equal to or less (better) than 0.7 milligal (mgal); and
2. A 'time to steady‑state registration' of two minutes or less;
Technical Note:
In Item 6A107.a.2., 'time to steady-state registration' (also referred to as the gravity meter's response time) is the time over which the disturbing effects of platform-induced acceleration (high frequency noise) are reduced.
b. Specially designed components for gravity meters specified by 6A007.b. or 6A107.a..
6. A. 108. Radar systems and tracking systems, other than those specified by entry 6A008, as follows:
6. A. 108. a. Radar and laser radar systems designed or modified for use in space launch vehicles specified by 9A004 or sounding rockets specified by 9A104;
Note: 6A108.a. includes the following:
a. Terrain contour mapping equipment;
b. Imaging sensor equipment;
c. Scene mapping and correlation (both digital and analogue) equipment;
d. Doppler navigation radar equipment.
b. Precision tracking systems, usable for 'missiles', as follows:
1. Tracking systems which use a code translator in conjunction with either surface or airborne references or navigation satellite systems to provide real‑time measurements of in‑flight position and velocity;
2. Range instrumentation radars including associated optical/infrared trackers with all
