Le satellite Es'Hail 2 avec transpondeurs radioamateurs
The Es’Hail 2 satellite
The Es’Hail2 satellite is first and foremost a Qatari commercial and geostationary satellite. Here is some information about it: It weighs 3 tons, equipped with an installed power of 15 kW in solar panels and Lithium Ion batteries, it was built by MELCO (Japan’s Mitsubishi Electric Corporation). It was launched on November 15, 2018 from the Kennedy Space Center, Cape Canaveral, Florida by a SpaceX Falcon 9 launcher. The opening to amateur radio traffic was completed on February 12, 2019, two days before the official inauguration of the Phase 4A satellite then named the Qatar Oscar 100 operational satellite.
The satellite transponders
The satellite is equipped with two transponders for amateurs:
- A transponder for narrow-band modes (NB: Narrow band)
- A transponder for broadband television transmission (WB: Wide band)
The table below specifies the descent frequencies, which will be received for both transponders. You notice that the two transmissions are not made with the same wave polarization.
