Small satellites: Possible future WRC agenda item

The *CEPT CPG-PTA-8* meeting in Catania, Sicily, July 21-24, discussed a
number of issues related to WRC-15 among them a paper submitted by The
Netherlands - Small satellites: further aspects for the development of a
future agenda item.

The paper summary says:

Following proposals from 12 CEPT members, WRC12 decided to place the
subject of nanosatellites and picosatellites on the WRC19 agenda for
adoption at WRC15.

Since then a growing number of small satellites, launched year on year has
been recorded, and a growing number of diverse applications has been
implemented ranging from technology demonstration and research to Earth
observation. The applications of these small satellites vary widely, but
all of these satellites have one common need which is Telemetry, Tracking
and Command (TT&C). Providing for proper TT&C will allow positive satellite
control at all times, and, when combined with ranging capability, may
provide for orbit determination as well which in turn can aid in the
tracking of space objects.

At this moment, the study work under the related agenda item 9, issue 9.1.8
which deals with regulatory aspects for nanosatellites and picosatellites
is finished. The studies have indicated a number of difficulties in the
application of the Radio Regulations. These difficulties, however, do not
justify a change of Articles 9 and 11.

Considering that most bands currently used for satellite telemetry and
command such as the 2200-2290MHz SRS/SOS/EESS allocation are heavily
crowded, the growth in numbers of small satellites launched offers new
challenges which were not faced before. Therefore, the proposal for AI 10
is to invite ITU-R in the forthcoming study period to identify additional
allocations to the space operation service (SOS) within the 137MHz-960MHz
range. This frequency range is particularly suitable for small satellites
since it offers favourable propagation characteristics while allowing
moderately complex antenna systems and antenna pointing requirements on
board the satellite.
