Abstract: FIELD: radio-measuring equipment engineering, possible use in rocketry, space industry, aviation industry, whenever it is required to perform continuous control and compression of measured data. 
     SUBSTANCE: method for controlling loads of a construction during operation of a space station with utilization of onboard autonomous multi-channel system for controlling dynamic processes includes delaying measurement signals for a time of analysis, comparing each current value of measurement signal to prior values thereof and in case when difference of values exceeds allowed value, marking signal is generated about deviation of an appropriate parameter of measurement signal for tolerance, prior to beginning of experiment to aforementioned onboard autonomous multi-channel system n indicators are connected, positioned in sections of space station of different lengths and measuring micro-accelerations or overloads, onboard power, and system is adjusted to working levels by inputting first mark for information analysis, appropriate for threshold level, and second mark, appropriate for limit level for analysis of dynamic process, time of experiment beginning or system operation beginning is registered, appropriate for astronomical operation time of space station and system is enabled in autonomous operation mode, while inside the system measured signals from n indicators are amplified and filtered to match given range of filtering frequency, each measured signal from n indicators is transformed to digital code, digital information is analyzed in accordance to given algorithm, in accordance to which each signal received by system with frequency (for example 50 Hertz) is compared to given signal, appropriate for first mark and in case if current signal is below given first mark, signal is generated about time of insignificant information A<A thr  and analysis of signals from indicators is continued until receiving values of signals, exceeding first mark, while a signal is formed about time of end of insignificant information, time of beginning and end of insignificant information receipt is memorized and all signal which never exceeded A thr  in system are excluded, and received signals exceeding first mark A>A thr , each one serially, are compared to prior signal, extreme signal is determined, and signal is generated, proportional to oscillations amplitude, and signal, proportional to time of generation of extreme, all extreme signals are memorized by levels for analysis of amplitudes and number of cycles is calculated, and if measured signals are received from indicators, proportional to second mark, appropriate for limiting level of oscillations amplitudes A>A thr , command is sent into the system for registering information about processes by all measured parameters with increased registration frequency, for example, 200 Hertz during five seconds, and signal is generated about registration of limiting level for visual observation, indicating an unexpected load level, and all information about analysis results by system is memorized and stored until transmission to Earth via communication channels during time, comfortable for receipt, then analysis process is continued in accordance to order set by method. 
     EFFECT: possible receipt of required information about space station during its operation process.
