Ground System for acquisition of remote sensing data
The hardware and software system for acquisition of Earth remote sensing data (HSS DA) is designed to receive radio signals from payload data radio transmission lines coming from the Earth Remote Sensing Satellite (ERSS), and carry out their demodulation, decoding, registration and temporary storage.
1. The Belarusian-Russian High-Throughput Acquisition System (BRHTAS)
The Belarusian-Russian High-Throughput Acquisition System (BRHTAS) has been designed to acquire and record payload data coming via X-band radio channels from Earth remote sensing satellites.Antenna system's plate diameter: 9 meter.
Received signals RF range: 7,75 – 8,5 GHz.
Received RF signals polarization:
- Right-hand circular polarization;
- Left-hand circular polarization.
Antenna Gain to Noise Temperature Ratio, G/T:
- 35,4 dB/K on RH polarization;
- 36 dB/K on LH polarization.
Types of modulation of received signals: BPSK, QPSK, OQPSK, 8PSK, 16APSK, 32APSK.
Received signals Modulation Rate: from 1 to 350 MBouds.
Currently, payload information is being received from the Kanopus-V series of satellites, the MetOp SG-A, AQUA, SUOMI NPP, NOAA (20, 21), Fengyun-3 (D, E, F) meteorological satellites, and CubeSat series of satellites.
2. The L/X-band signals receiving station
The L/X-band signals receiving station has been designed to receive, demodulate, decode, and record information from the two radio channels of Remote Sensing satellites.Antenna system's plate diameter: 3,5 meter.
Received signals RF range:
- 1,69 – 1,71 GHz for L-band;
- 7,75 – 8,5 GHz for X-band.
Received RF signals polarization: Right-hand circular polarization.
Antenna Gain to Noise Temperature Ratio, G/T: 26 dB/K.
Types of modulation of received signals: BPSK, QPSK, OQPSK, 8PSK, 16APSK, 32APSK.
Received signals Modulation Rate: от 1 до 350 MBouds.
Currently, payload information is being received from the «MetOp-(В, С, SG-A)», «AQUA», «SUOMI NPP», «NOAA (20, 21)», «Fengyun-3 (D, Е, G)» meteorological satellites, and CubeSat series of satellites.
