4.2 Experiments on board of an AN-30 aircraft with a 
TC217 CCD camera 
The preliminary tests of the main parameters and characteristics 
of a high-resolution HRC-P camera prototype were made in 
April 1999 on board of an AN-30 aircraft. 
4.2.1. Technical parameters and characteristics of the 
aircraft equipment. Nominal parameters for AN-30 flights are: 
speed 430 km/hour at an altitude of 6000 m. The aircraft is 
equipped with standard navigation, radio communication and 
landing equipment including an integrated navigation system 
Bendix /King/VOR/GS/DME/RBAV/ type K.NS80, an aerial 
GPS (Global Positioning System) a navigation receiver type 
Trimble TNL2000 and a meteorological radar with vertical 
profile Bendix/King type /RDS 82 VP 36. 
The photographic section of the aircraft is equipped with five 
portholes with optical windows. Three are directed downward 
and the other two are made for side observations. Figure 4 
represents the AN-30 onboard equipment 
4.2.2. Description of the experiments. The purpose of the 
experiments carried out was the imaging of a strip from the 
north air trace (fig. 2) with the laboratory CCD camera and the 
processing of the data obtained. During the flight the following 
parameters of the system were tested: 
- CCD matrix performance; 
- suitability of different types of objectives; 
- suitability of different types of filters sensitive to light; 
- parameters of electrical voltage produced by the parallel 
generators of the aircraft;
