APGI operates as follows. Antenna post 3 receives a continuous signal from the artificial satellite of the Earth (geo or HEO), phase modulated information signal, which is formed from devices from the heliogeophysical hardware system on Board an artificial satellite of the Earth. External receiving device 4 connected to the antenna post 3 and the hardware is implemented on the basis of the bandpass filter 5 and the low-noise amplifier 6. The bandpass filter 5 and the low noise amplifier 6 provides a preliminary signal amplification and filtering from industrial noise. Antenna post 3 may be used either in manual or program mode guidance. Manual for the introduction is used to set the initial direction of the antenna at a precisely known position of the geostationary artificial satellite of the Earth. For subsequent tracking antenna post 3 of the trajectory of motion of artificial Earth satellite is enough to use the software guidance antenna post, which is provided by the guidance system and the automatic tracking 19 according to information from the hardware and software of computer system that is part of the complex APPLI.

The signal after amplification in the low-noise amplifier 6 is fed to a power splitter 7, which is a passive reactive element, which is designed to split the signal between one input and multiple outputs, in particular the two outputs. The received signal power is evenly distributed to all outputs of the divider with minimal losses. Power divider 7 provides:

- given the uneven division of power in the band of operating frequencies;

the desired frequency;

- coordination of all outputs and inputs with load;

- high isolation between outputs.

The first and second analog-to-digital receivers 9 and 10 solve the following tasks: detection and capture of the signal in the noise, the measurement of carrier and clock signal frequency, the measurement of the level of information of the energy potential of the index modulation of the received signal, filtering the signal at the intermediate frequency, an analog-to-digital conversion of the signal in ADU and demodula the s signal, moreover, the demodulation signal is in digital form. The results of the signal processing in the form of information packets and Protocol (RS-232 and/or USB is transmitted in the first and second computing system blocks 11 and 12, where the subsequent signal processing.

The first and second analog-to-digital receivers 9 and 10 operate as follows.

The input microwave signal (signal FC) increases the second low-noise amplifier 30 with a gain of at least 20 dB and mixed in the first mixer 31 with heterodyne signal from the output of the first buffer amplifier 39 of the first controlled oscillator 38, covered by the signal control its frequency ring phase-locked loop frequency in the first frequency synthesizer 42, signal input which receives the signal from the first controlled oscillator 38, and the second input signal of 10.0 MHz reference oscillator 46. The difference frequency signal from the first mixer 31 of the first conversion 148.5 MHz bandpass filtered by filter 32 with a bandwidth of 3 MHz and amplified in the intermediate frequency amplifier 33 with adjustable gain and then mixed in the second mixer 34 with heterodyne signal of the second controlled oscillator 40 par 144, 0mm MHz, the second frequency synthesizer 43. The filtered signal to a second intermediate frequency to the nominal frequency is the frequency of 4.5 MHz is summarized in the third mixer 35 with the output signal after the second bandpass filter 41, on which input signal clocking F formed by the digital receiver 45. The resulting signal is amplified in the second buffer amplifier 36 and is served in the two devices is in the third buffer amplifier 28, the output of which is fed to the control connector "Control", located on the front panel of the first and second analog-to-digital Converter 9 and 10, the amplitude detector 27 loop automatic gain control and analog-to-digital Converter 37, where it is digitized.

The signal connector "Control" may be filed, for example, to the spectrum analyzer for control channel signal APPY.

The output signal of the second controlled oscillator 40 of the second frequency synthesizer 43 is divided in frequency by 4 divider 44, and the received signal clocking to 36.0 MHz is supplied to a digital receiver, 45.

Digital receiver 45 handles 8-bit samples coming from the analog-to-digital receiver 37. In receive mode digital receiver implements the following functions: detecting the signal, estimation of signal parameters, signal phase error in the phase-locked loop circuit on the carrier and the frequency control digital lo signal demodulation, the allocation information symbols and the formation of the error signal synchronization circuit according to the beat of the howling frequency and the control frequency synthesizer clock frequency. Received information packages containing 224 bytes heliogeophysical information each, are packaged with the measurement information with information about the importance of carrier and clock frequency of the received signal level of the received signal, the magnitude of the modulation index and the time of reception of the frames are selected and fed to the first and second computing system blocks 11 and 12 port USB and/or RS-232.

In the simulation mode of the digital signal receiver 45 generates a modulation signal F, which contains footage of the heliogeophysical information with precisely known area framing. The modulation signal F supplied to the LPF 29, where it is filtered, and then may be filed, for example, to the input of the phase modulator external frequency generator signal heliogeophysical complex 1693 MHz. Thus formed signal enables the health check of the first and second analog-to-digital converters 9 and 10.

The first and second computing system blocks 11 and 12 are designed to solve problems of the receiving stream information frames from the analog-to-digital receivers 9 and 10, normalization and preservation accept heliogeophysical information in the database, generate estimates of the carrier and clock frequency of the received signal and outputting the normalized information p is the consumer. Received information frames stored in the buffer of the computing system unit, a capacity enough to store at least ~20 frames (4480 bytes) heliogeophysical information. Next is the selection and retention in a database, generating estimates of the carrier and clock frequency of the received signal is tied to the current time.

Simulator onboard signal source 8 is used for debugging and offline testing APGI in General, and for controlling the operation of APGI in the course of its operation. In case of failure or malfunction of the onboard complex heliogeophysical information spacecraft simulator onboard signal source 8 is required to confirm the performance of APGI.

Simulator onboard signal source 8 provides the installation level, carrier frequency and modulation index of the signal and the data transfer speed with high precision and can be built on a standard generator (for example, AgilentE4428C), managed the first and the second computing system blocks 11 and 12 and first and second d / a converters 14 or 15.

As the first and second digital to analogue signal Converter 14 and 15 can be used, for example, the card installed on the PCI bus on the first and second computing system blackah and 12.

The first and second computing system blocks are as follows.

Is receiving flow heliogeophysical information (operation 47) from the first and second analog-to-digital receivers 9 and 10, then checks for the presence of heliogeophysical information in the stream (operation 48), in the presence of heliogeophysical information flow is the state of the simulator onboard signal source (operation 52), if the simulator onboard signal source is in the on state, turns off the simulator onboard signal source (operation 51) and starts checking heliogeophysical information in the stream (operation 48), if the simulator onboard signal source is off, the normalization of heliogeophysical information in allocating service parameters and the definition of identifier devices heliogeophysical hardware complex, completeness check target information devices heliogeophysical hardware complex pre-processing parts of the heliogeophysical information with the aim of obtaining a set of physical parameters measured by the instrument heliogeophysical hardware complex bound to maternity Moscow time, the binding of the target information to maternity Moscow time (operation 56), C is the when condition for the successful implementation of normalization in the test result holding normalization (59) is normalized heliogeophysical information in the database (operation 62), then there is a check account, normalized heliogeophysical information in the database (operation 64), and if the normalized heliogeophysical information recorded in the database, it is normalized transmission heliogeophysical information external customers (operation 68), and if the entry is validated, normalized heliogeophysical information in the database (operation 64) is negative, then the test is run first and the second computing system blocks (operation 67), and if the result of checking the fidelity of the test first and the second computing system blocks (operation 66) is positive, then starts normalization heliogeophysical information (operation 56), if the result of check fidelity test first and the second computing system blocks (operation 66) is negative, then the indicator to the operator fails APGI (operation 65). Also with a negative test result holding normalization (59) test is performed first and the second computing system blocks (operation 67). If checking heliogeophysical information in the stream (operation 48) gives a negative result, then it turns on the check pointing of the antenna system on the spacecraft (49), and if the antenna system is not induced on the spacecraft, it is on the introduction of the antenna system on the spacecraft (operation 50), then check the availability of heliogeophysical information in the stream (operation 48), if the validation step guidance antenna system on the spacecraft revealed that the antenna system is positioned on a spacecraft, checked the time synchronization (operation 53), and if the time is not synchronized, then checked the access to the Internet (operation 54), if you have access to the Internet start time synchronization over the Internet (operation 55) and then checks for the presence of heliogeophysical information in the stream (operation 48), in the absence of access to the Internet when checking for the existence of access the Internet (operation 54) time synchronization occurs by the operator (operation 58), and then checks for the presence of heliogeophysical information in the stream (operation 48). If the check time synchronization (operation 53) shows that the time is synchronized, check the status of the simulator onboard signal source (operation 57), and if the simulator onboard signal source is turned off, turn on the simulator side signal source (operation 61), and then checks for the presence of heliogeophysical information in the stream (operation 48). If you check the status of the simulator onboard signal source (operation 57) shows that the simulator onboard signal source s is n, it is under the control of the hardware (operation 60), then, if the result of technical means (63) is positive, going off simulator onboard signal source (operation 51), and then starts checking heliogeophysical information in the stream (operation 48). If the result of the test of technical means (63) is negative, then there is indication to the operator fails APGI (operation 65).

When testing offline point of the heliogeophysical information enabled to receive and process the continuous tone channel heliogeophysical information speed of receiving data up to 20 kbit/s from the spacecraft "Electro". The selection of a continuous flow of information is ensured with high probability, namely the probability of erroneous reception of the bits was less than 10"5during continuous operation, and the accuracy of synchronization of the system time APGI was no worse than 1 C.

SUBSTANCE: in one aspect, power control (PC) is supported in several PC modes such as "up-down" PC mode and delete-based PC mode. One PC mode may be selected for use. Overhead may be sent to indicate the selected PC mode. If the "up-down" PC mode is selected, a base station assesses the quality of the received signal for the terminal and sends PC commands to instruct the terminal to adjust its transmission power. If the delete-based PC mode is selected, the base station sends delete indicators which indicate whether code words received from the terminal are deleted or not. In both PC modes, the terminal controls its transmission power based on a power control feedback (e.g. PC commands and/or delete indicators) in order to attain the desired level of efficiency (e.g. desired delete frequency for code words). Delete indicators may also be used for handover.

EFFECT: reduced noise and achieving high efficiency for all terminals.
