Amateur community always at foreground of innovation:
•
Qualifying the first CMOS chips in space.
•
Performing the first Doppler shift analysis to locate ground-based beacons leading to the COSPAS-SARSAT Search & Rescue
system.
•
Validating the first inter-satellite communication link.
•
Demonstrating the first GPS receiver in High Elliptical Orbit (HEO).
•
Development of packet radio protocols which are still used in many commercial systems.
•
The use of CubeSats.
•
The design of the first DVB-S2 Ka-Band transmitter for small satellites.
•
Operation of the world’s largest distributed ground segment, as a precursor to Ground station-as-a-service offers which are now
commercial offered.
QO-100 leading to additional innovation, but with specific GEO-focus (DVB-S2, higher bands, IoT, ranging,…)
Some of us want to see a follow up of QO-100: w
e would like to support the definition of a future GEO amateur payload.

Letter to ESA Director: “Could
ESA support in defining a future
amateur satellite GEO
payload?”
“Can we have some budget to
support this request? We find it is
a good thing.”
“OK do it, but please with some
focus then on European/Canadian
amateurs”

How to “request” work from the amateur community?
Could ESA support with other means ? (travel, in-kind contributions,…)
Amateur satellite communities play a vital role in innovating and pushing boundaries in space technology. This document highlights past achievements and proposes the development of a future amateur satellite payload with a focus on European and Canadian radio amateurs. The goal is to consolidate requirements, explore payload options, and investigate financing, procurement, and operational aspects. Input and collaboration from the amateur community are essential in shaping the next steps for this exciting project.

Definition of a future amateur satellite GEO payload ESA Satellite Communications Group September 2023 Frank.Zeppenfeldt@esa.int 1 ESA UNCLASSIFIED For ESA Official Use Only
Background Amateur community always at foreground of innovation: Qualifying the first CMOS chips in space. Performing the first Doppler shift analysis to locate ground-based beacons leading to the COSPAS-SARSAT Search & Rescue system. Validating the first inter-satellite communication link. Demonstrating the first GPS receiver in High Elliptical Orbit (HEO). Development of packet radio protocols which are still used in many commercial systems. The use of CubeSats. The design of the first DVB-S2 Ka-Band transmitter for small satellites. Operation of the world s largest distributed ground segment, as a precursor to Ground station-as-a-service offers which are now commercial offered. QO-100 leading to additional innovation, but with specific GEO-focus (DVB-S2, higher bands, IoT, ranging, ) Some of us want to see a follow up of QO-100: we would like to support the definition of a future GEO amateur payload. 2
Background Can we have some budget to support this request? We find it is a good thing. Letter to ESA Director: Could ESA support in defining a future amateur satellite GEO payload? OK do it, but please with some focus then on European/Canadian amateurs Amateur community 3
Small print The coverage of the payload should be such that in particular European and Canadian radio amateurs will benefit, not precluding any international collaboration with other radio amateurs. ESA proposes that this activity will be implemented by a combination of internal, industrial, and amateur efforts. The activity shall: consolidate requirements from the amateur community and commercial satellite industry, trade-off several payload options, address the future user segment, develop scenarios on how to finance, procure and operate such a payload, and investigate hosting opportunities on geostationary platforms. 4
