Frequencies announced for HamTV from the International Space Station

Basic amateur radio station which should receive HamVideo from the ISS – Image AMSAT-Italia

Frequencies have been announced for the new Ham Radio Digital TV transmitter that will send video from the ISS in the amateur radio 2400 MHz band.
The main mission of HamTV is to perform school contacts between the astronauts onboard ISS and the scholarship, not only by voice, but also by unidirectional video from the ISS to the ground within the ARISS program.
In addition to the existing VHF radio amateur station, ISS will host a S-Band video transmitting station. This new equipment can broadcast images from the ISS during the school contacts or other pre-recorded video images up to 24 hours a day to allow ground stations tuning.
It is planned to transmit DVB-S signals on 2.4GHz at either 1.3Msps or 2.3Msps with 10 watts of RF from the ISS Columbus module.
The IARU Amateur Satellite Frequency Coordination Panel have announced frequencies of 2422.0 MHz and2437.0 MHz.
HamVideo is the name of the onboard DATV S-band transmitter. HamTV is the name of the complete system, comprising DATV downlink and VHF voice uplink. Kaiser Italia SRL was the prime-contractor for the design and development of the flight and ground segment http://www.kayser.it/index.php/exploration-2/ham-tv
It is understood that the HamTV equipment will be carried to the ISS on the Japanese HTV-4 spacecraft currently planned for a launch on August 4.

这应该接受HamVideo从国际空间站基本业余无线电台 - 图片AMSAT-意大利

频率已经公布了新的业余无线电数字电视发射机，将发送的视频从国际空间站业余无线电2400 MHz频段。
HamTV的主要任务是将ARISS计划内执行板载国际空间站的宇航员和奖学金的学校联系，不仅通过声音，而且还从国际空间站单向视频到地面。
除了现有的甚高频无线电业余电台，国际空间站将举办一个S波段视频传输站。这种新设备可以在学校接触器或其他预先录制的视频图像最多一天，让地面站调整24小时播放从国际空间站的图像。
它计划发射的DVB-S信号的2.4GHz的在任1.3Msps或2.3Msps与国际空间站哥伦布模块10瓦的RF的。
该IARU业余卫星频率协调小组已宣布2422.0 MHz和2437.0 MHz的频率。
HamVideo是板载DATV S波段发射机的名称。 HamTV是完整的系统的名称，包括DATV下行链路和VHF语音的上行链路。凯撒意大利SRL是黄金承包商为飞行和地面段的设计和开发http://www.kayser.it/index.php/exploration-2/ham-tv
据了解，该HamTV设备将被运送到国际空间站上的日本HTV-4号飞船目前计划于8月4日发射。
