[amsat-bb] EsHail Microwave transponder satellite

[Gregory Beat]

The Es’Hail-2 satellite (Es’hailSat – the Qatar Satellite Company) will be in geostationary orbit at 25.5 degrees East, planned launch for December 2016 (SpaceX Falcon 9).  
The coverage area of the amateur radio Narrowband (NB) and Wideband (WB) transponders should extend from Brazil to Thailand (~ 50° West to 100° East longitude).

Expected hardware requirements: 

X-Band 10 GHz Downlink:
– 89 cm dishes in rainy areas at EOC like Brazil or Thailand
– 60 cm around coverage peak
– 75 cm dishes at peak -2dB
– NB: linear vertical polarisation
– WB: linear horizontal polarisation

S-Band 2.4 GHz NB-Uplink:
– narrow band modes like SSB, CW
– 5W nominal Uplink power (22.5 dBi antenna gain, 75cm dish)
– RHCP polarisation

S-Band 2.4 GHz WB-Uplink (DATV):
– wide band modes, DVB-S2
– peak EIRP of 53 dBW (2.4m dish and 100W) required
– RHCP polarisation
