Geostationär amatörtransponder

Det händer hela tiden nya intressanta saker inom satellithobbyn och nu kommer informationen att vi är på god väg att få vår första geosatellit transponder.

Om den här förverkligas fullt ut så kommer vi i Sverige kunna nå den då jag i södra SM har den i riktning 165 grader AZ samt 24 grader EL.

Jag har gjort en liten simulering vad positionen 26 grader öst betyder och bifogar även det brev som Peter DB2OS i Amsat DL har skrivit.
Es’HailSat-2 will carry two geostationary ?Phase 4? amateur radio transponders !!

As a result of a concept proposed by the Qatar Amateur Radio Society,
Es? Hailsat, the Qatar Satellite Company, have announced that their new,
geostationary, Es’HailSat-2 Communications will provide transponders for use by radio amateurs. The spacecraft is expected to be ready for launch by the end of 2016.
Es’HailSat-2 will provide a 250kHz linear transponder intended for conventional analogue operations in addition to Another transponder which will have an 8MHz bandwidth. The latter transponder is intended for experimental digital modulation schemes and DVB amateur television.

Precise uplink and downlink frequencies remain to befinalized but the uplinks will be in the 2.40-2.45GHz and the downlinks in the 10.450-10.500GHz amateur satellite service allocations.  Both transponders will have broad beam antennas to provide full coverageover about 1/3rd of the earth?s surface. Precise operational plans will be finalised over the coming months but it is anticipated that only quite simple ground equipment will be required to use this satellite.

A team of amateurs, led by Peter Guelzow DB2OS (President of AMSAT-DL)
are providing technical support to this ground breaking project which is expected to
provide an exciting new phase of activity for radio amateurs for the 21st century.

Det händer hela tiden något intressant även i våra dagar då man ofta tror att man sett allt.
