Looking down on earth, through satellites! Nanometer wavelength monitoring during the night when the Belgian weather permits it.

It was about time I framed these up! Once again big thanks to @esa!

Calling all radio amateurs! We want your help catching the first signals from #OPSSAT, ESA’s first-of-a-kind space laboratory

Launch is set for 17 Dec. The first three amateurs to receive its beacon will win cool #MissionControl prizes

Just how I like my satellites, bright and fast moving! Optically tracking Metop-A 🛰️🔭 #IspyMetop @eumetsat

@ly5ez @astro_niks @DutchSpace @Marco_Langbroek Hi Edgar, the software is sending positional commands to a GOTO-mount with a telescope on it (60mm objective lens). With the current imager, the FOV in this case is around 1.5° x 1°.

Opto-electronic tracking of ancient russian upper stages, what do you usually do in the evenings? 🛰️🔭 @astro_niks @DutchSpace @Marco_Langbroek

[BE Satcom @BE_Satcom]

@DutchSpace Luckily they are not moving towards the restaurant building at the left 🙂

[BE Satcom @BE_Satcom]

@DF3LZ Is the frequency always shifting lower? Looks pretty steady in the FFT to me. Could also be a drifty LO in the TX of these devices.

[BE Satcom @BE_Satcom]

@astro_niks I truly have no idea, I just gave it a go! Wider fov will work even better, you'll see even more of them! Fov here was less than 1°

[BE Satcom @BE_Satcom]

@astro_niks Thanks for your kind words! 😃

[BE Satcom @BE_Satcom]

Was able to image some GEO sats! Timelapse shows BADR-4, 5, 6 & 7. Each frame is a 30 sec exposure. Total time around 1.5h @astro_niks

[BE Satcom @BE_Satcom]

@DF3LZ These are uplinks from M2M devices using low rate FSK. Can be anything from industrial equipment sensors to asset tracking devices.

SARSAT transponder repeating 406MHz NFM voice up in L-band. Noise floor is noticeably higher on the transponder. Right is Inmarsat Aero #sdr

GOES-16 eclipse animation.

[BE Satcom @BE_Satcom]

Watching the solar eclipse like a boss! https://t.co/VZsmaJ9wli

[𝙐𝙎𝘼 𝙎𝙖𝙩𝙘𝙤𝙢™ @usa_satcom]

Dishes pointed at both GOES-15 and GOES-16 for the solar eclipse. Should be some good shadow animations possible.

[BE Satcom @BE_Satcom]

Orbcomm sure as hell dominates the 137 MHz band on this 3 hour plot! Can you spot the NOAA and METEOR sats?

[BE Satcom @BE_Satcom]

@Croatia_uW @tomppa77 Actually, L-TAC payloads are hosted on GEO sats, the NFM in question here is most definetely from a MEOSAR payload :)

[BE Satcom @BE_Satcom]

Some very old school PCM/FM 256kbps telemetry on 166 MHz from Soyuz and Progress back in the day!

FY3B CHRPT pass. Sometimes direct overhead passes are not so good.

[BE Satcom @BE_Satcom]

@sxpert1 The Russians have been using these TLM signals for ages, even on Mir! It's just normal PCM/FM @ 256 kbps but framing could be proprietary.

[BE Satcom @BE_Satcom]

In case you wondered what the 600 MHz telemetry from the Russian Zvezda module from ISS looks like!
