The launch date of the Meteor-M apparatus No. 2 is July 8, 2014.
A global observation of the atmosphere and underlying surface of the Earth, which allows systematically obtaining hydrometeorological and heliogeophysical information on a planetary scale.
Spectral ranges of shooting microns:
Coverage (when shooting from orbit 835 km) - 2800 Spatial resolution (projection of a pixel onto the Earth with H = 835 km) - <1.0 km
The number of spectral channels - 3 Spectral ranges of shooting microns:
Coverage with two simultaneously operating cameras - 900 km Resolution - 60-120 m
The carrier frequency of the probe signal is 9500-9700 MHz Shooting bandwidth - at least 600 km Spatial Resolution:
The letters GY in the abbreviation are added in honor of Gennady Yakovlevich Guskov (1919-2002), an outstanding designer of space devices, who stood at the origins of the development of a new direction in the field of microwave sounding of the Earth.
The following software is used to receive images from the Meteor-M 2 satellite:
Launch SDR # and select the type of radio: RTL-SDR connected via USB.
In the Radio section, set the switch to WFM mode and set the Bandwidth to 34000.
Make sure the “Filter Audio” checkbox is unchecked.
Next, you need to increase the signal gain. To do this, click on the gear.
Move the slider so that the noise level rises by about 10dB.
This is what the signal from the Meteor-M 2 satellite should look like.
In the Tracking DDE Client section, when Orbitron is connected correctly, information about the tracked satellite will appear.
Launch Orbitron and update TLE first. Click on the tool button.
Press the zipper button to update the TLE.
Then select the weather satellite information file. Click the Download TLE button.
Download the weather.txt list
In the side list on the right, only weather satellites will appear. Choose Meteor-M2, NOAA15, NOAA18, NOAA19.
The selected satellites will be shown in the main program window.
Then go to the Calculation tab and click on the Calculation button.
The satellite will automatically calculate the time of flight. Go to the Rotor / Radio tab and make sure the tracking button is pressed. In the window with the reception frequency (Dnlink / MHz) the following correct frequency should be set: Meteor M2 - 137.10 MHz
To decrypt signals received from the Meteor-M 2 satellite, there is a special Meteor-M 2 LRPT Analizer program that receives an audio signal received from the satellite using the SDR # program. When a satellite signal appears, the Meteor-M 2 LRPT Analizer program starts automatically.
The signal quality can be determined by the diagram in the upper left corner of the program. A good signal quality is a satellite at a height of 50 degrees above the horizon.
Excellent signal quality - satellite at a height of 85 degrees above the horizon.
Signal strength information is displayed below the chart.
In SDR # it can be seen that the satellite signal level is more than 20 decibels above the noise level.
On the left, images in the visible range will appear line by line, and on the right in the IR range.
When you click the Generate RGB button, the final image will be generated.
A special window opens with the received image, which can be saved.
Analyze the resulting image and try to find cities and geographical objects on it yourself.
Compare the image with the image taken earlier, and see how the situation in the atmosphere has changed.
