3400 MHz and 10 GHz – ARRL’s comments on WRC-15

Logo WRC RA 2015The ARRL has commented on two draft recommendations of the FCC’s 2015 World Radiocommunication Conference (WRC-15) Advisory Committee (WAC) as well as on a draft proposal provided to the FCC by the National Telecommunications and Information Administration (NTIA).

Regarding 3400 MHz they say:
“[The] failure to even superficially address the protection of all existing services — including the Amateur and Amateur-Satellite services — is glaring,” the ARRL said. The WAC’s so-called “View A” — to make no change in the allocation — in part said, “The secondary nature of the Amateur Service allocation requires flexibility in frequency selection to permit an Amateur Service licensee to use the allocation and fulfill his or her obligation not to cause harmful interference to the numerous primary services, including the FSS [Fixed-Satellite Service].”

On 10 GHz the ARRL supported the FCC WAC view on Agenda Item 1.12 that the US not be added to international footnote 5.480 — basically an exception — to the Table of Allocations that could make part of the 10.0-10.5 GHz segment vulnerable to additional allocation for Fixed Service applications. The Amateur and Amateur-Satellite services have a secondary allocation in the band, and the Federal Radiolocation Service is primary. The proposed “footnote amendment,” the League argued, “plainly, clearly, and indisputably contradicts existing United States regulations.” The League’s comments accused Mimosa Networks, which has argued in favor of having the US sign on to the international footnote, of advancing an “illogical construction to obtain the result it desires.”

This Monday, January 26 there will be a presentation on the FUNcube-1 (AO-73) and SO-50 satellites at the Hog’s Back Amateur Radio Club near Farnham.

Mike Parkin, G0JMI, will give a talk entitled: Amateur Radio Satellites: A General Overview and Understanding of FUNcube-1 (AO-73) and Saudi-Sat 1c (SO-50).

Satellite operation is not quite as daunting as it can at first appear, and Mike will enlighten the audience with some of his experiences, as well as the equipment and techniques used for satellite communication.

Doors open at 7:30 pm for 8:00 pm on Monday, January 26, 2015 at the Crondall Scout Hut, Pankridge Street, Crondall, Farnham, Surrey, GU10 5RQ. As usual the kettle will be on to provide the refreshment.

Jan 15 Talk – A Beginners Guide to Amateur Satellites

David Bowman G0MRF giving a previous FUNcube talk at the Sutton & Cheam Radio Society

David Bowman G0MRF will be giving a presentation titled ‘A Beginners Guide to Amateur Satellites’ at the Sutton & Cheam Radio Society (SCRS) on Thursday, January 15 at 8 pm, visitors are welcome.

The SCRS newsletter says:

Last February, we had an excellent and well-attended talk by David Bowman – GØMRF on the topic of ‘The FUNcube Satellite Project’. The technology of satellite communication seems to have caught the interest of many of our members, but what has been missing at our meetings so far has been an illustrated talk on the basics of getting started.

David will be paying us a return visit on Thursday 15th January with a talk entitled ‘A Beginners Guide to Amateur Satellites’. This will cover the development of amateur satellite communications along with plenty of information on the necessary equipment to get started and the techniques employed.

Some amateur satellite operators have extremely sophisticated and no doubt expensive station set-ups,
however, it is possible to start off at a very basic level. All will be revealed at this meeting.

It’s always good to see a good turn-out of members and visitors at our meetings, so hopefully we can ‘kickoff’ 2015 with a packed clubroom. See you all on Thursday 15th.

John – GØBWV

The meeting will be held in the Vice Presidents’ Lounge, Sutton United Football Club, The Borough Sports Ground, Gander Green Lane, Sutton, Surrey, SM1 2EY at 7:30 pm for 8:00 pm.

Signing of memorandum of understanding for HAMSAT II – Credit AMSAT India

The Economic Times report Dhruva Space, a two-year-old start-up co-founded by space technologist and ham radio operator Sanjay Nekkanti VU3ISS/AB3OE, sealed a deal with AMSAT India on November 30, 2014 to develop HAMSAT II.


HAMSAT I – VO-52 – was a very popular amateur radio satellite

It will be the successor to HAMSAT VO-52 which went silent on July 11, 2014 due to the failure of the on-board lithium ion batteries. HAMSAT provided a valuable communications resource for the amateur radio community for over 9 years.

Dhruva’s satellites are expected to be launched on ISRO’s workhorse Polar Satellite Launch Vehicle (PSLV). Nekkanti said his team is working closely with the space organization for design approvals and testing of the satellite.

The AMSAT India Secretary Nitin Muttin, VU3TYG has released this statement:

We are pleased to announce that AMSAT India and Dhruva Space Pvt. Ltd. have signed a Memorandum of Understanding on November 30th 2014 to pursue the development of a follow up mission to HAMSAT launched in 2005 on-board the PSLV-C6. HAMSAT II is envisioned to fill the gap created by the recent end of life of HAMSAT and shall continue servicing the societal needs in disaster management, amateur/emergency radio communications and education.

Some of the contemplated payloads for HAMSAT II include:
• U/V Analog FM Transponder
• U/V Linear Transponder, 50 kHz
• APRS Digipeater
• Digitalker

COSMOS-2491 RS-46

Dmitry Pashkov R4UAB reports that the COSMOS-2491 satellite carries RS-46 operating on 435.465 MHz and 435.565 MHz (+/- Doppler).

The satellite was launched on December 25, 2013 and is in a 1,515.8 km by 1,489.1 km 82.5 degree inclination orbit.

COSMOS-2499 signals received by Dmitry Pashkov R4UAB

COSMOS-2499 (2014-028E) was launched on May 23, 2014 and is now in a 1,510.6 km by 1,158.8 km 82.4 degree orbit. Dmitry Pashkov R4UAB has received signals from the satellite on approximately 435.465 MHz and 435.565 MHz (+/- Doppler). On November 30 the satellite started identifying itself in Morse code on 435.465 MHz as RS-47.

Launch of Kosmos 2499There has been some mystery concerning the purpose of COSMOS-2499. In a post updated November 20, 2014 Anatoly Zak @RussianSpaceWeb wrote: Ground observations indicated that the mystery satellite had not exceeded 0.3 meters in size. Previously, two Rockot launches with trios of Rodnik/Strela-3M launches also carried Yubileiny (a.k.a. MiR) experimental satellites with a reported mass from 48 to 100 kilograms. As with the previous launch, observers were at a complete loss about the possible purpose of the satellite.

Cosmos-2499 has made a number or orbital changes since it was first launched. For further information see http://www.russianspaceweb.com/Cosmos-2499.html

OSCAR Locator App

OscarLocator-1Tom Doyle W9KE has developed a Windows satellite tracking App that reproduces the graphical display of the original cardboard OSCARLOCATOR .

Most tracking programs use an equirectangular projection which is by far the easiest to program and shows the entire Earth at once. A 3D model is often used which helps visualize orbits but does not show the entire Earth at the same time.

Tom remembers having an easier time visualizing the orbits back in the day (1970’s) when amateurs used cardboard OSCAR Locators with overlays. This Windows program lets you visualize orbits OSCAR Locator style.

SatNOGS Win Hackaday Prize

SatNOGS - Satellite Networked Open Ground Station

SatNOGS – Satellite Networked Open Ground Station

The open-source amateur satellite tracking project SatNOGS has won the Hackaday 1st prize and an amateur radio SDR won 3rd prize.

Six months ago Hackaday challenged their readers to realize the future of open, connected devices, The prize was a ticket to travel into space. The winners were announced at the Electronica trade show in Munich on November 13.

The SatNOGs project is a thrilling example of the benefits of a connected world. It opens up the use of satellite data to a much wider range of humanity by providing plans to build satellite tracking stations, and a protocol and framework to share the satellite data with those that cannot afford, or lack the skills to build their own tracking station. The hardware itself is based on readily available materials, commodity electronics, and just a bit of 3D printing.
