equipment's accuracy over time. This accuracy over time is defined for the instrument itself without reference either to a calibrated value or to a designated electrical value.

(iv) Direction finding equipment operating at frequencies greater than 5 MHz;

(v) Rated for continuous operation over a range of ambient temperatures extending from below -55°C to above +55°C.

Note:

Direction finding equipment specially designed for search and rescue purposes and operating at a frequency of 121.5 MHz or 243 MHz is not covered by this sub-item. This exclusion also applies to personal locator beacons operating in this form and which may also have an additional channel selectable for voice mode only.

(2) Ground and marine equipment for use with airborne navigation equipment utilizing the constant velocity or the rectilinear propagation characteristics of electromagnetic waves having frequency less than 4 x 1014 Hz (0.75 micron);

(3) Ground and marine direction finding equipment operating at frequencies greater than 30 MHz;

(4) Timing receivers whose only function is automatically providing time derived from satellite signals to within 1 millisecond of Universal Coordinate Time (UCT) or better;

(5) Ground or marine navigation and geodetic positioning systems designed for use with satellite-provided timing positioning or navigation information;

(c) Radar equipment as follows, and specially designed components, specialized testing, calibrating and training/simulating equipment, and "specially designed software" therefor:

(For lidar equipment see Item IL 1522)

(1) Airborne radar equipment;

(2) Ground and marine radar equipment having one or more of the following features:

(i) Operating at a frequency not in normal civil use or at a frequency of more than 10.5 GHz,

(ii) Operating at a frequency of less than 1.5 GHz and having a peak output power from the transmitter greater than 2.5 MW; or operating at a frequency within the range of 1.5 to 3.5 GHz and having a peak output power from the transmitter greater than 1.5 MW; or operating at a frequency within the range of 3.5 to 6 GHz and having a peak output power from the transmitter greater than 1 MW; or operating at a frequency within the range of 6 to 10.5 GHz and having a peak output power from the transmitter greater than 500 kW;

(iii) Operating at a frequency of less than 3.5 GHz and having an 80 per cent or better probability of detection for a 10 sq.m. target at a free space range of 250 nautical miles; or operating at a frequency within the range of 3.5 to 10.5 GHz and having an 80 per cent or better probability of detection for 10 sq.m. target at a free space range of 100 nautical miles;

(iv) Utilizing other than pulse modulation with a constant or staggered pulse repetition frequency, in which the carrier frequency of the transmitted signal is not changed deliberately between groups of pulses, from pulse to pulse, or within a single pulse; except civil commercial airport radars using a carrier frequency that may change from pulse to pulse between two fixed frequencies separated in time and in frequency by constant magnitudes;

(v) Utilizing a Doppler technique for any purpose other than M.T.I. systems using a conventional double or triple pulse delay line cancellation technique; except those utilized for surveillance and control radars for aerial navigation in civil airports;

(vi) Including any digital signal processing techniques used for automatic target tracking, or having a facility for electronic tracking;

(vii) Including signal processing techniques other than those covered by sub-item (vi) above, which have been in normal civil use for a period of less than two years;
