National Preparatory Working Group meeting for
World Radiocommunications Conference 2015
Aeronautical Agenda Items 1.5
Compiled by Tshifularo Sigwavhulimu
Agenda Item: 1.5
Title:
 To consider the use of frequency bands allocated to the
fixed satellite service not subject to Appendices 30, 30A
and 30B for the control and non-payload communications
of unmanned aircraft systems (UAS) in non segregated
airspaces, in accordance with Resolution 153 [COM6/13]
(WRC 12).
Relevant Resolution/s
 Resolution 153 [COM6/13] (WRC 12) – The use of
frequency bands allocated to the fixed-satellite service
not subject to Appendices 30, 30A and 30B for the
control and non-payload communications of unmanned
aircraft systems in non-segregated airspaces.
Issues
 technical, regulatory and operational requirements for the
operation of UAS using FSS Bands.
 sharing and compatibility of the use of UAS in FSS bands
with services already having allocations in those bands.
Frequency Bands under
consideration
 10.95-14.5 GHz and 17.3-30.0 GHz
Summary of Relevant ITU
SG/WP Progress
 Report ITU-R M.2233 contains examples of technical
characteristics for UA CNPC including FSS systems operating
in portions of the frequency ranges 10.95-14.5 GHz and 17.330.0 GHz. These examples indicated that it may be possible
to operate UAS CNPC links in these bands while meeting the
desired link availability.
 All studies invited by Resolution 153 (WRC-15) are included
in Report ITU-R M.[UAS-FSS]. These studies further refined
the work in Report ITU-R M.2233 by expanding the UA
system characteristics to reflect a better representative cross
section of FSS system performance and which can be
provided by most FSS system and network operators
worldwide.
Method(s) to satisfy the
agenda Item
 Method A
 To enable UA CNPC applications in certain frequency
bands allocated to the fixed-satellite service (FSS) under
special provisions.
Preliminary SA Position
 South Africa supports conducting of the necessary
studies leading to technical, regulatory and operational
recommendations to the WRC-15, enabling the decision
on the usage of FSS for the CNPC links for the safe
operation of UAS in non-segregated airspace.
Conclusion
 It is imperative that studies are conducted to provide a
basis for considering regulatory, technical and
operational conditions, in order to use fixed-satellite
service (FSS) links for the CNPC link between
geostationary satellites and unmanned aircraft systems
in non-segregated airspaces in a compatible manner with
incumbent services in the FSS frequency bands.
 For unmanned aircraft to be allowed access to airspace
where manned aircraft operate, the unmanned aircraft
will have to demonstrate that they can operate in that
airspace and interact, where necessary with air traffic
control, in a manner that is comparable to that of
manned aircraft.
