    Using C band kit to monitor Inmarsat Aero H/H+

    During the Christmas and New Year period , to celebrate over ten years of PlanePlotter , COAA is offering the software at a reduced registration fee of just 15 Euros plus tax [ normally 25 Euros pt ] PlanePlotter offers not just ADS-B tracking but much , much more. It can be configured to...

    Using C band kit to monitor Inmarsat Aero H/H+

    Hi, a word of warning about Alphasat...its not as strong as some of the other satellites so a 90cm dish may not be big enough. 63 east might be a better option. Its always best to try both polarities and experiment with the position of the dielectric plate to get the best signal. Planeplotter...

    Using C band kit to monitor Inmarsat Aero H/H+

    Another from the archives. Inmarsat 4F2 is located at 63 degs east....it was launched back in 2005 and the video above shows it moving through space just after launch towards its test location.

    Using C band kit to monitor Inmarsat Aero H/H+

    A bit off topic , but as we are talking about inclined satellites ....the video above is from 2004. I created it using telescope and webcam to demonstrate to Eutelsat what happened to their 13 east fleet during eclipse . This happened during the Sun Outage period , when the shadow of the earth...

    Using C band kit to monitor Inmarsat Aero H/H+

    Yes , 54 west is a bit of a pain as it is quite well inclined...add to that the signal drift and as you say , its a challenge. Ideally what I would like to do is set up the network so that , in the case of the more inclined sats , one dish ground station looks at the upper part of the arc ...

    Using C band kit to monitor Inmarsat Aero H/H+

    Fantastic work Brett ! No dropped packets there , which is great. If you decide to feed into PP [ which I hope you do ] then make sure that in JAERO you select the port as localhost 8765 [not 18765] and tick output to UDP. In PP tick ACARS from JAERO.

    Using C band kit to monitor Inmarsat Aero H/H+

    I need to pay more attention to the drift and frequency "jumps" Interestingly the 10khz jumps now seem to be taking place around 1000-1100 GMT , as the satellite approaches the arc from the north. Time permitting I will try to log the movements. Meanwhile Bev is continuing with the " work in...

    Using C band kit to monitor Inmarsat Aero H/H+

    Yes , the 10khz "jump" is interesting , usually around 0700 gmt and again late afternoon in the opposite direction. At least one other user has observed this. Personally I thought it was satellite related , possibly some sort of shift initiated by Inmarsat for some reason....but that seems...

    Using C band kit to monitor Inmarsat Aero H/H+

    Hi Titanium....I should make it clear that my comment was in no way a criticism of the PLL LNB , it was more aimed at my inability to do the mod ! The drift I see is only about 30khz , well within the design spec of the product. Interestingly the signal drifts in two ways...I see a 10khz "jump"...

    Using C band kit to monitor Inmarsat Aero H/H+

    Good point spongella , although I use both the basic dongle and the slightly more expensive one and find little difference for this type of application. I do however struggle a little with temp drift on the lnb. I'm not proficient enough to do the recommended modifications as explained here...

    Using C band kit to monitor Inmarsat Aero H/H+

    Something I forgot to mention. If you are planning to give this a go , the latest version of PlanePlotter actually tracks the Inmarsats for you in real time so that you can see exactly where the birds are in relation to the arc. This helps to position your dish accurately as some of the western...

    Using C band kit to monitor Inmarsat Aero H/H+

    Following the disappearance of MH370 back in 2014 Inmarsat offered to provide free 15 minute check ins for commercial Oceanic flights via their ADS system. This was to encourage operators to log in with their location on a more frequent basis. The company conducted tests last year which were...

    Titanium Satellite PLL LNBF OSMOCOM Hack

    Thanks for the welcome Michael I'll create a starter thread in this section if that's OK with you. Be great to get a few more satellite ground stations up and running ...and its a great project to have a go at :O) Best wishes John

    Titanium Satellite PLL LNBF OSMOCOM Hack

    Hope no one minds me updating the thread here , but above is the latest development from PP for those receiving and viewing ADS from Inmarsat at C band. Thanks to some hard work by a number of dedicated sharers we now have a wide network of satellite ground stations .....but we still need more...
