Welcome to my Webpage!

I am very interested in receiving data from meteorological satellites.
This page contains information about my work in this direction.



Start receiving APT by means of receiver R-45.



Making EMGO receiver and writing firmware for it.



Building the 1.7 GHz --> 137.5 MHz downconverter and receive Meteosat -6, -7.

Using 1.85 m parabolic dish.



In octobre 2008, has purchased a license and start receiving



Making HRPT equipment and start receive (C)HRPT in Nov 2008.

The equipment consists of a receiver HPR-137, a old decoder Rob Alblas,

1.20m offset parabolic antenna, Az/El rotor and LVB tracker.



Building home-made 1.90m parabolic stressed antenna.

More info about home-made stressed parabolic dish -> read in my article (rus).



After some time I finished decoding the new russian satellite Meteor M N1.

See my descriptions data transmission ---> Decoding Meteor M N1 HRPT.pdf

Many thanks to my friends for help !


After the problems associated with the "dead zone" at the zenith, I decided to build X-Y rotor.

For construction, we used two mount PowerTech DG380 with metallic gear.

I wrote (in Delphi) a plugin for Orbitron to control the X-Y rotor.

Also changed firmware LVB tracker for X-Y mount ver. 1.0.


November, participated in the project ENVI-HAM, start receive Envisat DDS-data
(image with a resolution of 250 m / pixel).


In december obtained Aoyama decoder (from Japan) for receptions HRPT.

Aoyama decoder also decodes Meteor-M N1. See more ...

Thank you very much Mr. Aoyama for help !



Modification and construction of the new receiver for HRPT.

Start receiving Meteor-M N1. Complete description of the format MHRPT here.


This year, thanks to my friends I met with Gnuradio and the USRP1 receiver.

With Gnuradio now have the opportunity to take all the L-band satellites.


Start developing a new converter (1691MHz-->137.5MHz) on modern components.



The final protocol was analyzed FY3A and FY3B Chinese satellites. See my research....

It was also completed production of two version of the downconverters.

Made recalculations and manufactured patch feed for prime focus dish with f/d =0.3-0.5


Was purchased on Ebay modem SLM-7650.

It will be used for receiving satellites in QPSK modulation.


Written MetFY3x Processor software to decompress CADU frames

satellite Metop-A/B and FY3A/3B.


Making simple QPSK, BPSK constellations viewer based on STM32 mini-board.

Written simple software for online viewing binary stream.



A lot of time spent on the development and manufacture hardware decoder for Chinese satellites.

Decoder is presented as a separate board that works together with a demodulator

SLM-7650 modem. More details here.


Designed and manufactured downconverter for X band.


Were purchased waveguide powerful gearboxes, stepper motors and a parabolic antenna of 2.3 m for X-band experiments.



All his spare time was devoted to the design, construction details, write software and firmware for the new X-Y rotor.

What came out - look here.



New X-Y rotor




Comstream Reader software




Binreader / FY3x Decoder board




X-band downconverter




Binary stream viewer



Simple constellations viewer



MetFY3x Processor software




Record data from SLM-7650 modem via USB




"Patch" feed 1700 MHz for prime focus dish.




Construction of the new "old" receiver HPR-137 for HRPT.

(update July 2012)

Building of the X-Y mount for data acquisition.

Most industrial installations for the reception of meteorological satellites use X-Y rotors. Choosing this type of rotor is not accidental. Medium speed in both axes, the absence of "dead zone" in the zenith and the problems associated to the crossing of the azimuth 0 degrees.

This is a small list of advantages of this type of rotor ....
