AMSAT-UK Colloquium 2019 Second Call for Speakers

Kents Hill Park Conference Centre Milton Keynes MK7 6BZAMSAT-UK is very happy to announce the 2019 AMSAT-UK International Space Colloquium will be held October 12-13 at the Kents Hill Park Conference Centre, Timbold Drive, Milton Keynes, MK7 6BZ.

We invite speakers, to cover topics about Amateur satellites, CubeSats, Nanosats, Space, High Altitude Balloons and associated activities, for this event. Those wishing to speak should contact Dave, G4DPZ, dave at g4dpz dot me dot uk

The weekend event attracts an international audience that ranges from those involved in building and operating amateur radio satellites to beginners who wish to find out more about this fascinating branch of the hobby.

We will be including a roundup of a number of new live and potential spacecraft projects that are under investigation and/or development.

Details of the event can be found at

CAS-7B ( BP-1B ) amateur radio satellite now ready for launch

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.

Satellite Name: CAS-7B/BP-1B
• Architecture: 1.5U Cube-satellite with flexible film ball
• Dimensions: 263Lx140Wx105H mm with 500 mm diameter flexible film ball
• Mass: 3kg
• Stabilization: Pneumatic resistance sail passive control

• Orbit type : LEO
• Apogee : 300km Circular orbit
• Inclination : 42.7º
• Period : 90.6min

• VHF Antenna: one 1/4λ monopole antenna with max.0dBi gain is located at +Y side
• UHF Antenna: two 1/4λ monopole antennas with max.0dBi gain are located at –Z and +Z side

Neil Melville-Kenney, PA9N, has been a long time supporter of amateur radio space since the days of the SSETI Express mission. He is presently the ESA Parabolic Flight Coordinator and today took the opportunity to fly a FUNcube patch during the ESA PFC 71 microgravity mission.

FUNcube Mission Patch

Neil presented an account of his activities during the 2018 AMSAT-UK Colloquium and the three FUNcubes, AO73, EO88 and JO97 continue to provide a 24/7 service with their 2 metre downlinks.

You can follow Neil on Twitter at

FUNcube Data Warehouse URL Change

Dave G4DPZ reports on a change to the URL used by the AMSAT-UK Data Warehouse for the FUNcube amateur radio satellites.

As part of the migration of the data warehouse to the new server, we are now redirecting all dashboard data submissions to:
(there is no need to change your dashboard settings)
Hence, all information at will no longer be updated.

I will be merging the scores at
(I am at the top of the list because of data migration)

You can search for your site name or order the columns by clicking on the column header.

There have been requests for the existing style of ranking, including age colour, for each satellite. I will be implementing this in the next couple of days.

Hope you like the new site and and feedback will be welcome.
