Amateur Radio Transponders on Planned Chinese Satellites to Include HF

China’s Amateur Radio Satellite organization, CAMSAT, has released some details of three new Amateur Radio satellites that could be launched as early as September. Two of the satellites, CAS-5A and CAS-6, will carry transponders, and one of them will have HF capability.

CAS-5A is a 6U CubeSat. It will an HF/HF (21/29 MHz) mode linear transponder; an HF/UHF (21/435 MHz) mode linear transponder; an HF CW telemetry beacon; VHF/UHF mode linear transponder; a VHF/UHF mode FM transponder; a UHF CW telemetry beacon, and UHF AX.25 4,000/9,600-baud GMSK Telemetry. Transponders will have 30 kHz passbands, except for the H/U unit, which will be 15 kHz.

The tiny CAS-5B, weighing 1/2 kilogram, will be deployed from CAS-5A in orbit. It will carry a UHF CW beacon on an Amateur Radio frequency. It will be placed into a 539 × 533 kilometer, 97.5° orbit.

CAS-5A/B will launch from the Jiuquan Satellite Launch Center.

CAS-6, a 50-kilogram microsat, will include a VHF CW telemetry beacon; a U/V mode 20 kHz linear transponder, and AX.25 4,800-baud GMSK telemetry downlink. It will also carry an atmospheric wind detector and other systems that will operate on non-amateur frequencies.

A launch at sea is planned for CAS-6 from the China Academy of Launch Vehicle Technology. The microsat will be placed into a 579 × 579 kilometer, 45° orbit.

CAMSAT has applied to the International Amateur Radio Union (IARU) to coordinate frequencies for all three spacecraft. — Thanks to AMSAT News Servicevia AMSAT-UK

Zhou Enlai student satellite launched


The 2U CubeSat Zhou Enlai 周恩来 developed with primary and middle school students was launched at 04:12 UT on Friday, January 19, 2018. 26 delegates from the satellite development student team in Huai’an who helped develop the CubeSat were at the Jiuquan Satellite Launch Center for the launch.

The satellite is named after the first Premier of the PRC, Zhou Enlai, who was born in Huai’an and held office from October 1949 until January 1976.

Zhou Enlai is listed as HA-1 on the IARU Satellite Frequency Coordination pages. It carries an FM transponder and has SSTV capability, the frequencies are at http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=589

Update April 29 Nico PA0DLO reports Zhou Enlai is object 43156, 2018-008B and appears to be active near 437.650 MHz. IARU list coordinated frequencies of 437.350 MHz for Telemetry and 436.950 MHz for FM Voice.

Also on the launch were the 6U CubeSats Xiaoxiang-2 (TY-2) and Yizhuang QuanTuTong-1 (QTT 1 / TY-6) developed by TianYi Research Institute in Changsha, Hunan Province, also known as SPACETY. TY-2 carries four experiments, testing optical fiber sensing technology, space radio software, Amateur Radio and image stabilization while TY-6 carries navigation and communication payloads (including AIS) along with the Amateur Radio payload. TY2 and TY6 both operate in the 435, 2400, 5650 and 5830 MHz amateur satellite service bands, further information at http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=556

Nico PA0DLO reports detailed Doppler measurements show that TY-2 is object 43155, 2018-008A, downlink: 435.350 MHz and TY-6 is either object 43157, 2018-008C, or 43158, 2018-008D, downlink: 436.100 MHz.

 

A Xinhua Net report on the Zhou Enlai CubeSat says:

The satellite was sent from its production base in Huai’an Youth Comprehensive Development Base in east China’s Jiangsu Province to Jiuquan Satellite Launch Center in northwest China’s Gansu Province Monday, where a CZ-11 solid fuel rocket is scheduled to put it into orbit Friday.

Twenty teenagers who participated in the development project accompanied the transport group to the launch center and will witness the lift-off.

Zhang Xiang, chief designer of the satellite, said that the nano-satellite, weighing 2 kilograms, is set to run in sun-synchronous orbit. Equipped with a HD optical camera, it can capture space photos with the highest resolution among those shot by other Chinese satellites for scientific education purpose.

Zhang said that the students had taken their spare time to join the development and groundbased simulation performance of the satellite, and had learnt to assemble and practice voice data transfer and telecommunication applications.

“A scientific satellite like this is like a teacher in space, carrying cameras or spectroscopes to study the upper atmosphere or to shoot space pictures of the stars. Students can grasp the mystery of the universe through the messages transmitted by the teacher,” said Zhang, a professor with Nanjing University of Science and Engineering.
