||Resolution 122, 145 [COM5/17]
|Description of work:
This agenda item relates to continuing the development of the regulatory framework for High Altitude Platform Stations (HAPS).
Firstly in the bands 47.2 - 47.5 and 47.9 - 48.2 GHz:
i) to encourage administrations to facilitate coordination between HAPS systems and co-primary satellite services, provisionally using Article 9 as a basis for procedures;
ii) to study power limits for HAPS ground stations to facilitate sharing with space station receivers;
iii) to study the regulatory provisions that might be needed to address the issue of a HAPS deployment in one administration effecting another;
iv) other issues relating to sharing with radio astronomy and GSO FSS;
Secondly in the bands 27.5 - 28.35 (HAPS to ground) and 31 - 31.3 (ground to HAPS) GHz, where HAPS shall not cause harmful interference to, nor claim protection from stations of other services:
v) to conduct studies including sharing with fixed service to identify a suitable and preferably common 300 MHz of the 27.5 - 28.35 GHz;
vi) to develop the necessary Recommendations on technical sharing criteria or HAPS system design conditions that are necessary to ensure HAPs can operate successfully on a non-harmful interference, non protected basis;
vii) studies of the interference criteria and methodology for evaluating interference between HAPS downlinks and GSO FSS Uplinks;
viii) to study the regulatory provisions that might be needed to address the issue of a HAPS deployment in one adminstration effecting another;
ix) studies relating to mitigation techniques for HAPS sharing with the fixed service;
|Lead Working Party(s):
|Involved Working Parties:
||WP 4A, 4-9S, WP 7C, WP 7D, WP 9B, WP 9D
|How Visualyse products can help:
||Visualyse Professional can be used to study compatibility between HAPS services, in both bands and in both directions, with other services including fixed service and fixed satellite service, including the aggregation from multiple HAPS systems.
|How Transfinite consultants can help:
||We can undertake studies including analysis of sharing between the services covered by this agenda item, and identify suitable system characteristics and sharing criterias, and provide contributions and representation at relevant ITU-R Working Parties. We have experience from work examining compatibility between a wide range of services, including fixed, aeronautical, and satellite, that allows us to analyse HAPS scenarios in detail.
