SMOG-1 pocket satellite reception how to

You can find all the Windows, Linux, Raspberry Pi based receiver software package here:https://gnd.bme.hu:8080/ So far the “best guess” for the Kepler element data is here:https://www.celestrak.com/NORAD/elements/tle-new.txt hint: for smogcli program you need to add -i 47939 ID for reception. Stay tuned for updated TLE elements, hope NORAD can do the radar measurements and fine tune Read more about SMOG-1 pocket satellite reception how to[…]

SMOG-P ACCOMPLISHES ITS MISSION

“The Earth-orbiting mission of the BME developed picosatellite has ended: it entered the denser parts of the atmosphere on September 28 2020 and disintegrated. After spending the sensationally long time of nearly 10 months in space, the world’s first functional pocket-sized (5x5x5cm) satellite, 1-PocketQube burned up in the atmosphere.  Despite a planned lifecycle of 3 Read more about SMOG-P ACCOMPLISHES ITS MISSION[…]

officeAir – A temperature and Humidity Meter and Google Sheet Logger with Raspberry Pi and I2C sensors

This project lets you log temperature and humidity data via Raspberry Pi and a sensor easily and automated way into you google sheet, collecting the raw data and automatically drawing a nice chart as data coming in. (The name and use case comes from life: initially we set this up to monitor DecentLabs office climate Read more about officeAir – A temperature and Humidity Meter and Google Sheet Logger with Raspberry Pi and I2C sensors[…]

RTL-SDR V3 based basic receiver station for SMOG-P and ATL-1 Nano Satellites

SMOG-P is currently the world’s smallest _operating_ satellite as far as I know. These wonderful tiny pocket satellites are designed in Hungary by the professors and students of Budapest University of Technology and Economics: “Apart from the units ensuring its basic operations, the payload of SMOG-P is a spectrum analyzer, measuring man-made electromagnetic pollution in Read more about RTL-SDR V3 based basic receiver station for SMOG-P and ATL-1 Nano Satellites[…]

Modifying EDUP EP-AB007 4W bi-directional Wifi amplifier for OA-100 Es’hail satellite operation, non-stop TX mode

4 and 8 Watt WiFi bi-directional amplifiers are designed for about 10-20 dBm input power. They listening in their input for a relatively strong signal to decide whether turn over to TX state from RX state (and changing over RF switches). Doing this simply rectifying the inrush RF power and leading that into an amplifier Read more about Modifying EDUP EP-AB007 4W bi-directional Wifi amplifier for OA-100 Es’hail satellite operation, non-stop TX mode[…]

Celebrating successful Es’hail 2 / QO-100 GEO HAM satellite WSPR transmission using only 4 milliwatts

Es’hail 2 / Qatar-OSCAR 100 bare LNB vs Parabolic dish reception test

Have seen an example of “bare LNB” reception of QO-100 GEO ham satellite from Andreas Preuss, DL5APR. That was quite shocking… So tried to reproduce that experiment using my own receiver setup. Looks like its works fine for stronger signals! I can imagine adding some tricks to the LNB’s horn antenna to improve it’s gain Read more about Es’hail 2 / Qatar-OSCAR 100 bare LNB vs Parabolic dish reception test[…]
