Qatar-OSCAR 100 (QO-100)

  • On 15 November 2018 Es'hail-2/P4A was launched with a SpaceX Falcon 9 launch vehicle from Cape Canaveral Air Force Station Space Launch Complex 40 in Florida. Es'hail-2/P4A was jointly developed by QARS (Qatar Amateur Radio Society) and Es'hailSat (The Qatar Satellite Company), under the technical leadership of AMSAT-DL, and is the first geostationary amateur radio payload. The satellite reached its final position at 25.9°E and the narrowband and broadband transponders were successfully tested on 23 December 2018 and 16-17 January 2019. The transponders are expected to open for general use in February 2019.

    At the request of AMSAT Deutschland e.V., QARS and Es'hailSat, AMSAT hereby designates Es'hail-2/P4A as Qatar-OSCAR 100 (QO-100). May the 100th OSCAR satellite be the lead star for future amateur radio satellites and payloads in geostationary orbit and beyond.

  • Hello all,

    Thanks for the information.

    Also, let me take the opportunity of this thread to hail involved teams and associated work.

    What a huge opportunity for the community to learn and progress with this project. I already have learnt a lot myself by preparing the set-up, being absolutely unexperienced above 400 MHz.

    All experience sharing on this forum has been very valuable as well.

    For all this, thank you !

    Hope everything will work here as expected, being in a hurry to meet you on QO-100 !

    73, Pat

  • Hi Peter,

    Congratulations to you, AMSAT-DL, QARS, and Es'hailSat. Very appropriate considering the giant leap (Pun intended) in capability this spacecraft will bring to the Amateur community. Thank goodness NEXUS (FO-99) worked :)



    (who must go and order the remaining uplink bits!, minor issue of an antenna to fix, the 30W PA needs something to dump it's power into, and a dummy load won't do!)

  • Dear Peter (DB2OS), I wonder if the inauguration ceremony will be broadcast on the WB transponder? Are you able to give any indication of the timing (in GMT) and video parameters, please?
