Enabling higher resolution services for the EESS by extended allocations in the 9.6GHz frequency range Presentation to New Zealand National Mtg Wellington, 3 August 2011

2 Extension of the allocation to EESS in the 9.5GHz range Very high resolution radar information is a key pre-requisite for enhanced environmental monitoring For considerations under AI8.2 (WRC-12): Administrations are invited to consider an extensions of the EESS allocation by 600MHz at WRC-15 Agenda Item 1.x (WRC-15) “To consider an extension of the current worldwide allocation to the Earth Exploration Satellite Service (EESS) (active) and the Space Research Service SRS (active) in the frequency band – MHz by at least 600 MHz within the frequency range – MHz in accordance with Resolution [EESS+600MHz](WRC-12)”.

3 Typical applications provided by EESS systems Applications and services provided by several systems worldwide comprise  Emergency response  Topographic Mapping  Forest Monitoring  Surface Movement  Change Detection  Maritime Applications  Geodesy and Cadastre And many others

4 Why future EESS systems should operate with higher bandwidth Very high resolution mapping and monitoring is required stipulating substantial socio-economic benefit  Disaster relief and humanitarian aid actions require ad hoc and up-to-date geoinformation also from the remote parts of the globe  Airborne imaging is very often limited by remoteness of the area to be observed and cloudy weather conditions  Current radar satellites are yet too low in resolution to allow adequate infrastructure damage assessment (and consequently a rough estimate of the number of affected people) to assist first responder activities  Identification of trafficable roads, landing strips or suitable spaces to set-up first aid or refugee camps is limited by the resolution of today’s radar sensors  Support of fight against Climate Change  Monitoring of deforestation and forest degradation – enabling the REDD+ process  Enabling Governments in developing countries can verify that their measures against deforestation and forest degradation have been successful even at a single tree level

5 Why future EESS systems should operate with higher bandwidth  Safety of energy supply  Ensuring sustainable oil and gas production by careful monitoring of sites and managing the extraction.  Monitoring the integrity of comprehensive pipeline networks - detect leakages to avoid severe environmental pollution.  Enable reliable and weather independent monitoring  Cadastre  To foster the economic development of developing countries by property ownership registration  High-precision cadastre is a major pre-requisite to maintain and develop properties by protecting agricultural and infrastructure investments  Especially countries in the tropical belt suffer from substantial cloud coverage while facing nations rapid built-up areas, growth and land cover and change of use of land  EESS can support affordable, reliable and weather independent mapping capacity A successful and sustainable integration of derived information only can be achieved in a very high resolution mode in the sub meter area to fulfill essential user requirements

6 Key criteria for a potential extension of the EESS (active) Current allocation in the ITU RR 9.3 – 9.9GHz => 600MHz  Doubling picture resolution compared to current 600MHz needs 1.2 GHz  Any extension should include the current allocation to ensure long-term continuity of observation data already collected for several years  The new allocation should be in the 9/10 GHz range: optimum compromise between high resolution (RF bandwidth) and all-weather propagation performance  Any extension of the allocation should be contiguous  Agenda Item should investigate sharing conditions for either 600MHz above, below, or any other appropriate apportionment between 8.7 … 10.5 GHz in any case the actual radar exposure time is in the order of seconds

7 Current Radio Regulations in the frequency range 8.65 – 10.5 GHz Optional extensions and radio services affected (ITU RR Ed. 2008)

8 Typical operating modes of EESS systems EESS satellites typically - perform about 15 Earth orbits per day - travel at about 500km altitude - are inclined by 97° (angle of orbital plane vs. the equatorial plane) => Track of sub-satellite points repeats every 11 days => Exposure times of a few seconds per snap shot

9 Typical RF characteristics of 1200MHz EESS Radars The compatibilities of similar EESS Radar systems with other radio services allocated in the band 9.3 – 9.9 GHz have been studied in Report ITU-R RS.2094 Carrier centre frequency9.6 GHz Transmit signal form Linear frequency modulation “Chirp” Signal bandwidth≤ 1200MHzDepending on mode of operation Pulse Repetition Frequency (PRF) ~ 5000Hz Transmit duty cycle (DC)~ 20 % e.i.r.p.
