HS10KING on QO-100 geostationary satellite



To strengthen the relationship between Thai and Japanese amateur radio operators representatives of the JAMSAT group of Japan have travelled to Thailand to visit the satellite ground station HS0AJ.

They will operate from the Ground Station of the Radio Amateur Society of Thailand under the patronage of His Majesty the King (RAST).

On the occasion of the coronation of His Majesty King Vajiralongkorn Bodindradebayavarangkun, HS10A (pronounced “Hotel Sierra-TEN-Alpha), as the 10th king to reign in the Chakri Dynasty, the National Broadcasting and Telecommunications Commission (NBTC), Thailand’s regulator, has authorized the special callsign HS10KING (pronounced “Hotel Sierra-TEN-KING).

There will be an opportunity to communicate with HS10KING using the QO-100 amateur radio satellite and low earth orbit (LEO) satellites that windows pass over Thailand by amateur radio stations which is similar to AMSAT Germany’s use of the special callsign DL50AMSAT using the QO-100 satellite.

RAST hence invites AMSAT amateur radio satellite operators to join in contacting the HS10KING special event station from June 22, 2019 at 10.00 UTC (17.00 Thailand time) until June 23, 2019 at 10.00 UTC (17.00 Thailand time) using SSB mode and DATV (333 – 250 KS) signals from the station HS10KING.

Please be informed and let others know of this opportunity.

Sincerely and with respect, de HS1JAN

Live streaming of the event is expected at https://live.ariss.org/

You can receive the ISS signal online from anywhere in the world by using the Farnham WebSDR at http://farnham-sdr.com/

School presentation

Rowan Preparatory School is a vibrant, friendly and nurturing community where girls are encouraged to be themselves. Our school is an independent preparatory school for girls between the ages of 2 to 11, located in the heart of Claygate (near Esher) in Surrey. A school with traditional values and a forward thinking approach to education, we seek to offer a broad and adventurous curriculum full of exciting opportunities.

School life at Rowan is inspiring and offers a breadth of experiences which develop the whole child. The warmth that is evident when you walk through the door at Rowan creates the ideal learning environment for girls to fulfil their potential. They are nurtured and allowed to grow as individuals, encouraged to take risks and have a go at new skills and interests which will enrich their lives. Science, Technology, Engineering and Maths are at the heart of the curriculum at Rowan. Girls make the most of our dedicated specialist teaching spaces and delight in practical learning opportunities in the Engineering and Technology suite. From 3D printers to our radio recording studio, the environment at Rowan is geared towards encouraging creative and exciting learning, ensuring that the girls explore, question and discover in every area of learning. We are passionate about bringing STEM subjects to life and encouraging the girls to see how these subjects translate into the world beyond school. Experiences which will foster successful and inspirational women of the future!

Rowan girls are prepared for the transition to a wide range of successful day and boarding schools and we pride ourselves on finding the right senior school environment for each and every girl. A personalised approach to learning and outstanding pastoral care in our happy environment, ensures that every girl develops a genuine love of learning.

Students Questions:

About ARISS:

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station: NASA, Russian Space Agency, ESA, JAXA, and CSA. The US Center for the Advancement of Science in Space (CASIS) and the National Aeronautics and Space Administration (NASA) provide ARISS special support.

ARISS offers an opportunity for students to experience the excitement of Amateur Radio by talking directly with crew members on board the International Space Station. Teachers, parents and communities see, first hand, how Amateur Radio and crew members on ISS can energize youngsters’ interest in science, technology, and learning.

The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

WRC-23 Agenda Items may impact 144 MHz and 1240 MHz bands

IARU Region 1 notes that there are two proposals under discussion in Europe as possible future Agenda Items at WRC 2023, which potentially could impact important amateur radio frequencies.

IARU Region 1 has posted:

The following sets out the current IARU position on these proposals.

A proposal from France to consider the band 144-146 MHz as a primary allocation to the Aeronautical Mobile service, as part of a broader consideration of the spectrum allocated to that service.

The band 144-146 MHz is allocated globally to the amateur and amateur satellite services on a primary basis. This is one of the few primary allocations to the amateur service above 29.7 MHz and as such is an important and widely used part of the amateur spectrum with a vast installed base of users and operational satellite stations.

IARU views with grave concern any proposal to include this band in the proposed study. It will be representing this view energetically in Regional Telecommunications Organisations and in ITU to seek to obtain assurances that the spectrum will remain a primary allocation for the amateur services.

A proposal to study the amateur allocation in the 1240-1300 MHz (“23cm”) band following reported cases of interference to the Galileo navigation system.

IARU is aware of a handful of cases where interference to the Galileo E6 signal has been reported. In all cases these have been resolved by local action with the full cooperation of the amateur stations concerned.

IARU does not want the amateur service to affect the operation of the Galileo system in any way. Joint studies have been carried out to assess the true vulnerability of the system and, based on these, IARU regards the proposal to initiate an Agenda item for WRC-23 as premature.

The IARU position is that proper technical assessment of the issues involved should be made in the relevant CEPT study group. Proper account needs to be taken of the operational characteristics of the amateur service in order to develop sensible and proportionate measures that will facilitate the continued utility of the band for amateur experimentation whilst respecting the primary status of the GNSS service.

IARU is ready to cooperate fully in any studies and shares the objective of reaching a secure and permanent solution to the issues of sharing in this band.

IARU asks its Member Societies to draw this information to the attention of their members, and to refrain at this time from making speculative public comments about the situation until further progress has been made in regulatory discussions. IARU is also ready to discuss this issue with other societies not in IARU membership.

CAS-7B ( BP-1B ) satellite is an amateur radio satellite combined with educational. Chinese Amateur Satellite Group ( CAMSAT ) is working the project with Beijing Institute of Technology ( BIT ), one of the most famous aerospace universities in China. The university provides support in launch of the satellite, there are many teachers and students from this university are participating in the development and testing of the satellite. With the help of CAMSAT, the university has established an amateur radio club (call sign: BI1LG), many students are the members, they are learning amateur radio satellite communication and experience endless fun.

Because of the orbital apogee and the size and mass of the satellite, the orbital life of the satellite is expected to be only one week, up to a maximum of one month, which will also provide with an opportunity for hams to track and monitor satellite entering the atmosphere.

The CAS-7B ( BP-1B ) is scheduled to be launched at the end of June 2019. The launch will use a new launch vehicle from a small commercial rocket company. This is the first launch of this launch vehicle, and there is a large possibility of failure, if the launch fails, we will have another launch later this year.
