Portable Installation Suite
for Receiving Meteor LRPT

One of the most daunting aspects of setting up a reception system for the Russian Meteor Satellites has been the intricacy of the procedure:
Install Orbitron
Install SDRSharp
Set up SDSRSharp features for LRPT reception
Add required Meteor and DDE Tracker plugins to SDSRSharp
Configure the Meteor plugins
Set up the DDE Tracking Schedule
Configure Orbitron to automatically run SDRSharp
Download Zadig.exe to install the RTL drivers for your dongle

Wouldn't it be great if all this could be achieved in a single step?

Well, it can be done.

Both Orbitron and SDRSharp are standalone programs. They can be run from any folder, on any drive of your computer, because all their configuration files, data files and DLLs etc. are present in their own folders - not hidden within the depths of Windows. It is therefore perfectly feasible to create a zipped archive which installs everything into the directory structure illustrated opposite.

Moreover, the link from Orbitron to activate SDRSharp has been made directory-independent: you can unpack the archive on any of your PC's drives (C\:, D\: etc.) and Orbitron will still link correctly with SDRSharp.

It is strongly recommended that you do not extract the archive into the Program Files folder, but directly on to one of your computer's drives: otherwise things may not run smoothly. For most users, it is sufficient to unpack the zipped archive directly on to the C:| drive when the directory tree illustrated will be installed.

The Archive Meteor LRPT Suite.zip installs the entire Orbitron/SDRSharp system into the LRPT folder and, in addition, adds a subfolder containing LRPTOfflineDecoder, and an empty QPSK subfolder where the received QPSK S‑files will be stored.

Thus, you have everything you need to receive Meteor images in a single location.

What the archive cannot do

There are still a few things that you will have to do to get everything operational.

Run zadig to install the RTL drivers for your dongle (you will find the zadig file inside the SDRSharp folder).
You will have to set the Tuner Correction (ppm) to precisely centre the frequency in SDR# for you own specific RTL dongle.
The Meteor frequency is set at 137.9 MHz in both Orbitron and SDRSharp.
  (You may have to alter this should the satellite switch frequency to 137.1 MHz in the future.)
You must enter your own Location Coordinates and Time Zone into Orbitron.

Once this is done, everything is set to go. All you need to do is run the file orbitron.exe from the 'Orbitron' folder, click the 'Rotor/Radio' tab at the foot of its display, and finally click the small button to the right of the 'Driver' window showing 'SDRsharp'. This will activate SDRsharp, and Meteor data will be recorded automatically on every pass, under control of Orbitron.

And of course, you must connect a 137 MHz APT antenna (turnstile, QFH etc) to your dongle in order to receive the Meteor signals. Your APT antenna for the NOA satellites is ideal.


If you are a newcomer to Receiving Meteor with a dongle, and need additional guidance, please refer to the detailed, illustrated article I wrote, which outlines every step in the process of setting up the system from scratch.

LRPT Suite for Meteor M2-2

This version of the Suite has been tailored specifically for the reception of Meteor M2-2.
Download Meteor LRPT Suite.2.3 for Meteor M2-2
(includes SDR# v 1555, Meteor Demodulator v 2.3 and LRPT Decoder v 52).

The above Suite operates well with the RTL-SDR dongle receiver, but I understand that it does not support the Airspy dongle.
The following version of the Suite, based on the more recent SDR# v 1707 has been tested and does work for Airspy reception.
Download Meteor LRPT Suite2.3 for Meteor M2-2
((includes SDR# v 1707, Meteor Demodulator v 2.3 and LRPT Decoder v 52)).

Important: Parameters for the satellite are set for a transmission frequency of 137.900 MHz and Symbol Rate of 72000.
There may be times when the frequency changes to 137.1 MHz. There may also be changes in symbol rate between 72000 and 80000.

There is an in-depth turorial explaining how to set up your Meteor M2-2 system from 'Happysat' at http://happysat.nl/Setup_Meteor/Setup.html,

LRPT Suite for Windows 7, 8, 10

Download Meteor LRPT Suite.1.7 using Meteor plugin v 1.7 (2015) and SDR# v
Download Meteor LRPT Suite.1.8 using Meteor plugin v 1.8 (2017) and SDR# v
Download Meteor LRPT Suite.1.8 using Meteor plugin v 1.8 (2017) and SDR# v
Download Meteor LRPT Suite.1.8 using Meteor plugin v 1.8 (2017) and SDR# v

Note 1 Windows 7 users must make sure that they have Microsoft's Dot NET 4.6 framework installed.
Note 2 These Suites will not run on the older Windows XP Operating System.
Note 3 If you update SDR#, be advised that some updates (v 1605 for example) do not work with the Meteor plugin.

LRPT Suite for Windows XP

Many enthusiasts make use of old Windows XP computers for Meteor reception.
To do this, a different Suite is required, using components developed to run on Microsoft's older Dot NET 3.5 framework .

Download QPSK LRPT XP Suite for Windows XP using QPSK plugin v 1.4 (2015) and SDR# v
Download Meteor LRPT XP Suite for Windows XP using Meteor plugin v 1.5 (2015) and SDR# v

It is perfectly OK to use an XP computer for Meteor reception, so long as it is kept off-line. Since the zadig driver installer has been included in the SDRsharp folder for you, there is no need ever to have this PC on-line.
Remember, Windows XP is no longer supported by Microsoft, and there is a danger of infection from Viruses and Malware if it is regularly connected on-line.
