5 Agenda Item 1.2: to consider in-band power limits for earth stations operating in the mobile-satellite service, meteorological-satellite service and Earth exploration-satellite service in the frequency bands MHz and MHz, in accordance with Resolution 765 (WRC-15). [Doc 4764] Preliminary proposal from CANADA BACKGROUND The bands MHz and MHz are used for uplink transmission by the Data Collection System (DCS) under the EESS, MetSat and MSS allocations. The DCS is a network of sensors measuring temperature, pressure, humidity, sea level, and tracking animal migration, located in areas difficult to reach. These measurements are indispensable for monitoring and predicting climate change; monitoring oceans, weather, and water resources. Additionally, these systems assist in protecting biodiversity, and improve maritime safety, and security. The data is transmitted to GSO and non-gso satellite networks using the non- GSO MSS allocation in the band MHz or the meteorological satellite allocation in the band MHz. These systems usually operate using moderate to low equivalent isotropically radiated power (e.i.r.p.) levels, resulting in small link margins. These frequency bands are also used by non-geostationary satellites for telecommand space operations (see RR No 1.23) under the EESS, MetSat services, or under the MSS allocations and a growing number of these satellites are planned. The output power levels of the earth stations at the antenna port peak e.i.r.p. of these telecommand links (Earth-to-space) can be much higher than the moderate to low power levels used for the DCS service links, leading to potential harmful interference to DCS satellite receivers. However, such links can deploy mitigation measures such as GSO orbit avoidance to minimize potential of interference to the DCS service links. Resolution 765 (WRC-15) Establishment of in-band power limits for earth stations operating in mobilesatellite service, the meteorological-satellite service and the Earth exploration-satellite service in the frequency bands MHz and MHz, calls for the necessary technical, operational and regulatory consideration of the possibility of establishing in-band power limits for earth stations in the EESS and MetSat services in the frequency bands MHz and in the MSS frequency band MHz. PROPOSALS As a result of the work carried out by ITU-R WP 7B and taking into account the example regulatory text in the draft CPM report, Canada proposes in-band power limits for earth stations in the EESS and MetSat services in the frequency band MHz, for earth stations in the MSS in the frequency band MHz, and for earth stations with telecommand links in both frequency bands as given in the Attachment. The values proposed for power density limits for the telecommand operations in part of the frequency band MHz used by DCS Geostationary and Highly elliptical orbit (HEO) satellites are based on the sharing analysis conducted by the ITU-R taking into account possible mitigation measures that can be used by the telecommand operations to minimize potential interference to DCS systems. For the frequency band , Method D in the draft CPM text proposes 20 khz to be available for potential use of telecommand and DCS operations without any applicable e.i.r.p. limits. Canada proposes to increase the 20 khz to 30 khz where the e.i.r.p. limit is not applied. This is done to accommodate the total assigned bandwidth of a typical, efficient telecommand link taking account of Doppler shift effects (e.g. typical link bandwidth of 9.6 khz + Doppler shift of +/- 8 khz). For the frequency band MHz, Canada proposes Method F with revisions to the power limits and regulatory provisions. Both Methods take into account the importance of maintaining operation of existing and planned telecommand functions for CITEL, 1889 F ST. NW., WASHINGTON, D.C , U.S.A.

8 telecommand operations. Until 22 November 2029, this limit shall not apply to systems for which complete Advanced Publication Information has been received by the Radiocommunication Bureau prior to 22 November Reasons: A non-gso system with a telecommand earth station operating with an e.i.r.p. density of 17.8 dbw/hz would be able to meet the protection criteria of DCS systems using GSO or HEO satellite systems. It is also important to preserve existing and planned telecommand operations in this band up to 22 November Furthermore, an e.i.r.p. limit is proposed for non-gso DCS with an orbit of apogee lower than km for the band MHz even though there are no such operations according to the DCS band plan, since non-gso DCS stations could nonetheless operate in this band under the METSAT and EESS allocations. ADD CAN/1.2/4 5.B12 In the frequency band MHz and MHz, the maximum e.i.r.p. of earth stations in the meteorological-satellite service and the Earth exploration-satellite service shall not exceed 22 dbw for geostationary systems and non-geostationary systems with an orbit of apogee equal or greater than km and 7 dbw for non-geostationary systems with an orbit of apogee lower than km. Until 22 November 2029, this limit shall not apply to systems for which complete Advanced Publication Information has been received by the Radiocommunication Bureau prior to 22 November Reasons: The frequency bands identified in this new footnote are intended for operation of non-gso DCS. Therefore, the long-term deployment of new telecommand earth stations in these frequency bands is to be avoided. However, it is important to preserve existing and planned telecommand operations in these frequency bands up to 22 November ADD CAN/1.2/5 5.D12 Operations for telecommand of the space stations (under No. 1.23) in the band MHz shall not constrain the use of stations operating under the Earth exploration-satellite and the meteorologicalsatellite services. Reasons: Administrations are encouraged not to constrain operation of DCS systems in this frequency band.

9 [Doc. 4357] Preliminary proposal from MEXICO BACKGROUND The bands MHz and MHz are used for uplink transmission by the Data Collection System (DCS) under the Earth Exploration Satellite Service (EESS) (Earth-to-space), the Meteorological- Satellite Service (MetSat) and Mobile Satellite Service (MSS) allocations. DCS consists in a network of sensors that are critical to monitor and predict climate change, monitor oceans and water resources, predict the weather, assist in biodiversity protection, and improve marine safety in areas that are hard to reach. In particular, the usefulness of DCS helps the scientific community to gain a better monitoring and understanding of the environment, and to help the industry comply with the environmental protection regulations implemented by some governments. In addition, these bands can be used for space operations under RR No. 1.23, which highlights the use of telecommand due to the great interest of educational institutions and commercial entities seeking to operate satellites under EESS, MetSat or MSS allocations in the frequency bands MHz and to MHz. So, the use of telecommand may cause great impact to the DCS communicating with GSO and non-gso satellite networks, since the power output levels of some telecommand earth stations transmit high levels of power that can be much higher than the moderate to low levels used by DCS links, which leads to possible harmful interference for satellite receptors using DCS. PROPOSALS As a result of the work carried out by ITU-R WP 7B, and in accordance with the provisions in the draft text of the CPM, Mexico is of the opinion that the power limits and time considerations established in Method D are suitable to allow the operation of DCS and telecommand operations in the frequency bands MHz and MHz. MOD MEX/1.2/ MHz Allocation to services Region 1 Region 2 Region 3 399,9-400,05 MOBILE SATELLITE (Earth-to-space) ADD 5.C12 ADD MEX/1.2/2 5.C12 In the frequency band MHz, the maximum e.i.r.p. of earth stations in the mobilesatellite service shall not exceed 5 dbw. Until 22 Nov 2029, this limit shall not apply to satellite systems for which complete notification information has been received by the Radiocommunication Bureau by 22 November 2019 and that have been brought into use by that date. The Administrations are encouraged to CCPII _i

10 make all practicable efforts to comply with the limits in the frequency band MHz prior to 22 November Reasons: We are of the opinion that these parameters would ensure the operation of existing and future systems that usually implement low or moderate output power for MSS systems, while they also accommodate systems with more power for telecommand. Likewise, the time considered as a transitional phase for high-power telecommand systems provides protection to the DCS for MSS. CCPII _i

Brazil OEA/Ser.L/XVII CCP.II-RADIO/doc /18 6 December 2018 Original: English PRELIMINARY PROPOSALS FOR WRC-19 AGENDA ITEM 1.3 (Item on the Agenda: 3.1 (SGT2)) (Document submitted by the Coordinator) SGT2B Science Services Coordinator: Coralí Roura (USA) Alternate Coordinator: Michael Razi (CAN) Rapporteur Agenda Item: James Mentzer (USA) Alternate Rapporteur Agenda Item: TBD CCPII _i

12 Source: Agenda Item 1.3: to consider possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-earth) to primary status and a possible primary allocation to the Earth explorationsatellite service (space-to-earth) in the frequency band MHz, in accordance with Resolution 766 (WRC-15) BACKGROUND Brazil The use of the frequency band MHz is already established due to the existence of a secondary allocation to MetSat. Meteorological satellites already transmit in this band to control and configure data collection platforms. Data Collection Systems (DCS) operate on geostationary and non-geostationary orbits in the MetSat and the EESS (Earth-to-space) systems in the frequency band MHz (uplink) and MHz (downlink). DCS are essential for monitoring and predicting climate change, monitoring ocean, and water resources, weather forecasting and assisting in protecting biodiversity, as well as improving maritime security. DCS have been operating globally under a secondary allocation and on a primary basis in some countries under RR No , but this use is constrained by coordination under RR No This has led to differing limitations and protection criteria and has posed a barrier to implementation of essential DCS components on a global basis. According to RR No , Earth exploration-satellite service applications, other than the meteorologicalsatellite service, may also be used in the bands MHz and MHz for space-to-earth transmissions subject to not causing harmful interference to stations operating in accordance with the Table of Allocations. One of the EESS/MetSat usages comprises the data collection platforms gathering information activity related to the Earth, the environment and scientific application, weather and environment observation. The data, which are collected by ground platforms, are sent to the corresponding satellites that retransmit the retrieved information to dedicated earth stations. DCS are particularly useful for the collection of data from remote and inhospitable locations where it may provide the only possibility for data relay. Even so, the system has very many uses in areas with a highly developed infrastructure. The installations required for relay of the data tend to be inexpensive, unobtrusive, and normally blend easily into the local environment. Amongst others, this band is currently used by the Brazilian Data Collection System (B-DCS), Advanced Data Collection System (A-DCS) also called ARGOS and many other types of satellites for non-gso and GSO orbits. DCS dedicated to studying oceans and atmospheric conditions, preserving and monitoring wildlife, volcanoes, fishing fleets, shipments of dangerous goods, humanitarian applications, and managing water resources. DCS help the scientific community to better monitor and understand our environment, but also help industry to comply with environmental protection regulations implemented by various governments. This positioning capability also permits applications such as monitoring drifting ocean buoys and studying wildlife migration paths. A primary allocation to the MetSat and EESS (space-to-earth) in the frequency band MHz would provide confidence to space and meteorological agencies deeply involved in Satellite Data Collection Programs and the public sectors funding the development and operation of such systems. These space programs have been representing a long term effort and investment for decades between the time when the program is officially decided, the development, the launch phase, and the time when the various satellites are in operation, keeping in mind that usually many satellites are deployed in order to CCPII _i

13 provide a continuous service. Space and meteorological agencies are also investing in the continuity of these programs providing subsequent satellites and payloads, and an allocation upgrade in the frequency band MHz would provide the necessary long-term continuity for these programs of public interest. In addition, the power flux density (pfd) limits will provide reliable protection to incumbent terrestrial services without imposing constraints. Mexico [4711c1] The meteorological-satellite service (MetSat) and Earth exploration satellite service (EESS) use Data Collection Systems (DCS), which consist in a network of sensors that are critical to monitor and predict climate change, monitor oceans and water resources, predict the weather, assist in biodiversity protection, and improve marine safety in areas that are hard to reach. In particular, the utility of DCS helps the scientific community to gain a better monitoring and understanding of the environment, and to help the industry to comply with the environmental protection regulations implemented by some governments. The frequency band MHz is allocated on a primary basis to the fixed and mobile services. It is also allocated on a secondary basis to the MetSat (space-to-earth) service. Moreover, in some countries of Regions 1 and 3, primary allocation is allowed by No of the Radio Regulations (RR). The operation of EESS applications is also permitted under RR No considering a no-interference and no-protection basis. In addition, channels in the MHz segment can be used for on-board maritime communications under RR No and No Primary allocation to MetSat and EESS services in the frequency band MHz may give confidence to the public sector and to space and meteorological agencies on the development of data collection systems and programs, as well as provide regulatory certainty. Therefore, parties interested in using the MetSat and EESS services are seeking to upgrade the MetSat allocation to primary status, and to include a primary allocation to EESS in the frequency band MHz while providing protection and not imposing additional constraints on existing terrestrial services nor adjacent frequency bands. PROPOSALS Brazil Proposal (Method B) Brazil s note: This proposal was based using the currently CPM text developed for the WG 7B and could be modifying if this CPM text have changes in the future meetings.

27 Source Document: 4712/18 Agenda item 1.5 of WRC-19: to consider the use of the frequency bands GHz (space-to-earth) and GHz (Earth-to-space) by earth stations in motion communicating with geostationary space stations in the fixed-satellite service and take appropriate action, in accordance with Resolution 158 (WRC-15); Background Earth stations in motion (ESIMs) currently serve a wide range of applications, both on board aircraft and ships and on land and, considering that users expect to be able to connect wherever they are, the broadband service satellite is a key component in meeting that demand. The 2015 World Radiocommunication Conference (WRC-15) adopted Note No A, through which the operation of ESIMs that communicate with geostationary satellite (GSO) networks of the Fixed Satellite Service (SFS) in the frequency bands GHz (Earth-to-space) and GHz (spaceto-earth) under to Resolution 156. However, recognizing the growing demand for mobile services and the global availability of satellite broadband, WRC-2015 adopted WRC-19 Agenda Item 1.5 to consider ESIM operation in the frequency bands GHz (Earth-to-space) and GHz (space-to-earth) of the FSS, thereby using more spectrum to meet the ESIM demand. Results of the ITU Radiocommunication Sector (ITU-R) The bands GHz and GHz are currently allocated to the FSS, among other services, and used by GSO Satellite FSS networks. These bands are shared with other services, including (in some sub-bands) non-geostationary orbital satellite (non-gso) satellite FSS systems, feeder links for non-gso systems for the mobile-satellite service and terrestrial systems. To protect other services assigned in these bands, different use conditions must be applied to the different types of ESIM, since scenarios of interference from other services will be different for maritime, aeronautical and terrestrial ESIMs. The results of the sharing studies on the ESIMs and the existing services in the frequency bands GHz and GHz are described below: The ITU-R reviewed the sharing conditions for ESIMs with terrestrial services in the band GHz and concluded that terrestrial service transmitters could potentially interfere with ESIM receivers. Therefore, ESIMs must function with the condition of not claiming protection against interference from terrestrial services operating in accordance with the RR. In the case of the frequency band GHz, the ITU-R reviewed the sharing conditions for ESIMs with terrestrial services in the band GHz and concluded that ESIM transmitters could interfere with terrestrial service receivers. Therefore, aeronautical and maritime ESIMs must operate under specific technical, operational and regulatory conditions to prevent interference with the receiving stations of terrestrial services and, likewise, ESIMs on the ground need to operate under conditions that do interfere with terrestrial services operating in accordance with the RR. Results of sharing studies with the Earth Exploration Satellite Service (EESS) (passive) The ITU-R examined sharing conditions for ESIMs with the EESS (passive) in the GHz band used by the EESS (passive) in remote sensing for Earth exploration, in which the EESS (passive) earth CCPII _i
