flying laboratory was used successfully is
IL-18-based (hull No 75423) regional monitoring system (Borodin et al. 1982).
Il-18 on-board complex is represented in Fig. 2.4 .
Flying laboratory IL-18 has given a possibility to solve numerous environmental
tasks practically in real time. On-board system represented in Fig. 2.4 registered
environmental characteristics and at the same time processed existing and delivered
by sensors information. Figure 2.5 explains a structure of on-board information-
modeling system that interrogated all sensors with time period equaled to 0.01 s and
taking into consideration of navigation information all results were referred to the
geographical coordinates.
