INTERNATIONAL AMATEUR RADIO UNION
REPORT THE IARU INTERNATIONAL
SATELLITE FORUM HELD IN TORONTO
19 OCTOBER 1997
INTRODUCTION
Some years ago it was recognized that the interest of the IARU and an
International Satellite Community would best served if the IARU
International Satellite Forum was held alternatively in conjunction with
the AMSAT UK Satellite Colloquium and the AMSAT NA Space Symposium..
This year was the first time that the Forum was held in conjunction with
the AMSAT NA Space Symposium. The symposium was held in Toronto from 17
- 19 October 1997.
AMSAT NA SPACE SYMPOSIUM
Several side meetings were held with the International Space Station
group primarily focusing on frequency planning for current SAREX and MIR
events and paving the way for international allocations for the ISS.
Various proposals were on the table. Tom Atkins, Region 2 IARU
President, also attended these discussions and together we formulated a
position paper which was shared via Email with the IARU AMSAT Frequency
Coordinator Graham Ratcliff. This paper was discussed at IARU
International Satellite Forum and accepted. (More later in the report).
At the AMSAT NA Space Symposium papers of a very high standard were
presented leaving one with the realization that research and development
by Radio Amateurs is alive and well. These development will not only
impact on satellite operation but will find their way into all
operational spheres of the Amateur Service. It supports the IARU
Administrative Council `s decision to establish an IARU AC Outlook
Committee so that these new developments can be shared more widely and a
need for the IARU PriCom group to pro-actively share these development
trends widely.
KEYNOTE ADDRESS
Hans van de Groenendaal ZS5AKV delivered the Keynote address at the
Annual AMSAT NA dinner attended by over 200 delegates. The title was
"Amateur Radio's contribution to Research and Development."
IARU INTERNATIONAL SATELLITE FORUM
The forum was held on Sunday 19 October 1997 and attended by 77
delegates including all the prominent players in the USA and Canada as
well as representatives from a number of European Countries.
The Forum was introduced by Ray Soifer on behalf of AMSAT NA and Tom
Atkins on behalf of IARU. The following topics we re discussed:
MONITORING OF SATELLITE FREQUENCIES
Hans van de Groenendaal reviewed the decisions taken by the Region 1
Conference to introduce such an activity and the agreement that Ron
Roden the IARU Region 1 IARUMS Coordinator would on a trial basis act as
coordinator.
The concept was agreed. The AMSAT NA Board will discuss the proposal and
formulate the way forward for the USA and Canada. It was agreed that the
ARRL should be approached to coordinate the input and any action taken
to remove violators and to keep Ron Roden in the loop.
It was also agreed that an education campaign was needed to enable
monitors to identify unauthorized operators especially in view of the
shared bands.
The view was also expressed that a paper should be prepared for
discussion at the Region 2 Conference. ZS5AKV was tasked to submit a
paper to the Region2 EC for their consideration and action.
ZS5AKV was also requested by the President of AMSAT NA, Bill Tynan W3XO
to submit an article for publication in the AMSAT Journal.
SATELLITE FREQUENCY COORDINATION
Tom Atkins VE3CDM took the floor and represented Graham Ratcliffe who
had submitted a number of issues for discussion.
The role of the IARU AMSAT Frequency Coordinator was discussed. It was
agreed that the terms of reference continue to apply. The coordinator's
function is to evaluate requests and make recommendations. In this
process he will often consult with other major satellite builders.
The coordinating function is not a regulatory or allocation function,
but a process to assist future satellite builders/operator to select the
best frequencies for their operation in order achieve the optimum use of
the available spectrum.
On the question when is a Satellite an Amateur Satellite it was agreed
that the criteria as set out in the AMSAT NA position paper on this
subject be applied.
It was agreed that the IARU Satellite Adviser should deal with these
issues and assist the Frequency Coordinator to resolve the status of the
request.
It was also agreed to circulate the AMSAT NA Position paper to all
Satellite Groups listed on the AMSAT- International Email list for their
acceptance. Ray Soifer will circulate the paper with a request that
feedback be sent within 30 days to the IARU Satellite Adviser.
.
BAND PLANNING
The question of band planning for satellite operation was discussed. It
was agreed that it is not a good idea. There is however merit in keeping
analogue and digital signals apart when and where practical. It was
agreed that the IARU AMSAT Frequency Coordinator should consider each
case on its merit.
USED BY DATE
It was agreed not to impose a used by date. The IARU AMSAT Frequency
Coordinator should however keep regular contact with Satellite groups
for which he has coordinated/ recommended frequencies.
WEDNESDAY- EXPERIMENTAL DAY
The meeting recommended that this be continued and that the IARU
Satellite Adviser and Frequency Coordinator promote more
experimentation.
REAPPOINTMENT OF THE IARU AMSAT FREQUENCY COORDINATOR
ZS5AKV proposed that Graham Ratcliffe VK5AGR be reappointed . This was
unanimously approved by the meeting. Several speakers recorded their
appreciation to Graham for his continued services to the satellite
community.
INTERNATIONAL SPACE STATION
Frank Bauer KA3HDO discussed the current problems experienced by SAREX
and MIR operations and the impact that these problems may have on the
International Space Station.
There are two basic requirements:
- A universal world-wide uplink frequency on two metres and
- A universal world-wide downlink frequency on two metres.
After intensive discussion it was recognized that the countries in
Region 1 had already compromised by making 144,490 MHz available as a
SAREX uplink.
AMSAT NA and ARRL have been working closely with TAPR and other USA
groups to make 145,800 MHz available as a downlink. Currently the
Automatic Reporting System (APRS) operates on 145,790 making 145,800
unusable for SAREX and Mir operations. All indications are that this
will be achieved in the short term.
The following proposal was unanimously accepted and will be put forward
to the next IARU Region 1 VHF meeting to be held in February 1998 in
Vienna and the Region 2 Conference to be held in Venezuela in October
1998. Representation also to be made to Region 3 . ZS5AKV and VK5AGR to
prepare the submission.
MANNED SPACE MISSIONS:
2 METRES
Uplink primary: 144,490 MHz World-wide
additional uplinks: 144,470 MHz and 144,450 MHz World-wide
Downlink primary: 145,800 MHz
additional downlinks 145,8125 MHz and 145,990 MHz (back-ups)
70CM
That two segments be set aside for manned-space operation:
435,700 - 435,800 MHz
437,500 - 438.000 MHz
Several meetings were held prior to the IARU Satellite Forum at which a
new schedule for MIR operation was proposed. The Forum endorsed the
proposal. Thomas Kieselbach DL2MDE of the DARC/SAFEX group undertook to
discuss the proposal with the MIR Ground Control Station.
1 December 1997 - 28 February 1998
70cm/2m operation to prove duplex working
Uplink: 437,850 MHz Downlink: 145,800 MHz
1 March 1998 - 31 May 1998
2 Metre operation
Uplink: 144,490 MHz Downlink: 145,800 MHz
After the experimental period the crossband operation to be continues
during odd months and 2 metre operation during even months.
OTHER UHF/MICROWAVE FREQUENCIES
There was unanimous agreement that higher frequencies above 70cm, new
modulation techniques and operating modes should be considered for
future manned space missions. The IARU Satellite Adviser and IARU AMSAT
Frequency Coordinator were requested to seek input from the Region One
VHF Committee and Regions 2 and 3 Executive Committee. It was also
proposed and agreed that they should make input to the IARU AC Outlook
Committee which is being chaired by Tom Atkins VE3CDM.
GENERAL
Bill Tynan W3XO, President of AMSAT NA asked that consideration be given
to approaching ITU about Amateur Satellite operation in the 50 MHz and
the 29,700 - 30,000 MHz bands. This was unanimously supported.. ZS5AKV
and VK5AGR to formulate a proposal to be submitted to the AC.
The meeting closed at 12:00 noon with a vote of thanks to AMSAT NA . The
next meeting is scheduled to coincide with the AMSAT UK Colloquium in
July 1998. The next North American IARU Forum will be held in 1999.
