Notes:

1 Welcome and Discussion of Agenda

Markus Rothacher opened the Steering Committee meeting and welcomed all participants. He pointed out that the later points on the agenda were the more important ones, and he asked the reports of the WGs and GEO representatives to be rather brief so that more time would be for the most relevant issues.

2 Minutes of SC9

The draft minutes of SC9 were made available as html and pdf . The minutes were not discussed in any detail. The participants were asked to identify necessary changes and/or corrections. No points were raised and the minutes were accepted as they are.

Markus Rothacher pointed to the list of Action Items and stated that most AIs were closed through appropriate actions or would be addressed in more detail later.

4 Brief report from the Chairs

Markus Rothacher presented the report of the chairs (see his presentation pdf ). He reviewed the activities since the last SC meeting and then reported on the events during the IUGG.

A key issue was the proposed change of the IAG By-Laws, which would consider GGOS as a full component of IAG, similar to the Commissions. There was some discussion of whether the IAG By-Laws need to be accepted by the IUGG or not.

The change of the IAG By-Laws also required a change of the GGOS ToR. Markus Rothacher briefly summarized the changes made to the GGOS ToR and the on-going process. The new draft ToR had been put to vote by e-mail to the SC, and the ToR had been accepted on June 28, 2007 with 30 Yes, 2 No, 2 Abstain. He emphasized that the ToR will have to evolve over the next year.

There was some discussion about the organizational diagram as developed in the GGOS 2020 process, which indicated that there is no clear consensus concerning the future structure and components of GGOS.

Markus Rothacher also gave an overview over the next GGOS-related events. Hans-Peter Plag emphasized the need to publicize the GEO/GGOS Workshop 2007 in IAG and outside. This resulted into

Action Item GGOS-SC10-1: All EC members will engage in publicizing the GEO/GGOS Workshop 2007 through appropriate channels. Responsible: Executive Committee, Deadline: 2007-08-15.

5 Brief GGOS WG Reports

There were two WG reports:

6 Brief GEO-Reports

7 GEO opportunities and GGOS contributions

Hans-Peter Plag presented a number of calls for contributions issued by GEO recently (see his presentation, pdf ). The following was decided:

Action Item GGOS-SC10-4: Markus Rothacher will follow up the GEO Call for a Notice of Interest to contribute to the Exhibition at the Ministerial Summit. Responsible: Markus Rothacher, Deadline: 2007-07-16.

Action Item GGOS-SC10-5: Hans-Peter Plag will follow up the GEO Call for contributions to the GEO publication "The Full Picture" and coordinate the production of the contributions for GGOS. Responsible: Hans-Peter Plag, Deadline: 2007-07-31.

Action Item GGOS-SC10-6: Bente Lilja Bye will follow up the GEO Call for contributions to the GEO Video Exhibition at the Ministerial Summit. Responsible: Bente Lilja Bye, Deadline: 2007-08-31.

8 GGOS 2020: Main conclusions and recommendations and next steps

Hans-Peter Plag presented an overview of the current status and the key remaining issues (see his presentation, pdf ) In particular, he summarized the comments received in the course of the internal IAG hearing. Most of these comments were easy to integrated, with only a few issues remaining. Concerning Chapter 7, the long list of products with some duplication was noticed. No comments were received concerning the functional specifications, which raised the question whether everybody agreed on these. The need for a full relativistic formulation of the future reference frame had been pointed out in some comments, and a more elaborate discussion of the future treatment of Earth rotation was requested. Concerning Chapter 9, it was emphasized in several comments that the necessary infrastructure was not clearly enough specified, while new and emerging technologies were not sufficiently integrated. Chapter 10 was critizised as being too IAG-centric and not open enough for other stakeholders. The recommendations we found to be not focused enough, not specfic enough, not prioritized, more like a shopping list.

Concerning the recommendations, it was agreed that Chris Rizos, Markus Rothacher, Ruth Neilan, and Hans-Peter Plag would meet on July 9, 2007 and review the recommendations in detail.

9 GGOS ToR

Markus Rothacher briefly summarized again the main changes in the ToR, which he had already addressed in the Chair's report (see his respective presentation ). He pointed out that the main goal of the recent modifications of the ToR was to bring the ToR in compliance with the new IAG By-Laws expected to be accepted the following day. Therefore, the part on vision, mission and task were not modified this time. However, in this respect, the ToR would have to be considered transient with more thorough changes to be worked out in the near future.

Following this up, Hans-Peter Plag presented ideas concerning new ToR (see his presentation, pdf ), where in particular proposals for new vision, mission and task descriptions were included. It was agreed to continue working on the ToR and to progress the work towards a better vision and mission statement during the next few SC meetings.

10 Future structural changes for GGOS (new components, WGs)

Markus Rothacher introduced this topic by pointing out the new elements of GGOS to be implemented, for which he used the latest version of the GGOS-organogram provided by Hans-Peter Plag (see jpg ). He emphasizing the need for implementing a GGOS office. In the discussion, it was agreed to call this office "Coordinating Office" (CO) instead of "Central Coordinating Office". He asked whether a Call for Proposals for the CO in November 2007 would make sense. Ruth Neilan requested that a Notice of Intent for such a call should be issued soon in order to alert potential bidders and to give them time to prepare the proposal. Hans-Peter Plag pointed out that UNESCO had voiced an intent to support a GGOS Office and suggested that the dialog with UNESCO was continued on the basis of the GGOS 2002 document.

Concerning the GGOS-organogram, Zuheir Altamimi commented that it was not clear where outreach was located. Bernd Richter suggested to keep the WGs in the diagram. Michael Pearlman pointed out that the name of the WG is Networks and Communication and suggested that the same title is used for the new entity in the organogram (instead of Communication and Networks ).

Concerning the CO, the following Action Items were agreed:

Action Item GGOS-SC10-7: Michael Pearlman, Ruth Neilan, Josef Adams, and Bente Lilja Bye will prepare a draft Notice of Intend and a draft Call for Proposals for the GGOS Coordinating Office and provide this to the EC. Responsible: Ruth Neilan, Michael Pearlman, Josef Adams, Bente Lilja Bye, Deadline: 2007-08-31.

Action Item GGOS-SC10-8: The EC will finalize the Notice of Intend for a CfP for the GGOS Coordinating Office and distribute this NoI to all potential bidders. Responsible: Executive Committee, Deadline: 2007-09-30.

Action Item GGOS-SC10-9: The EC will finalize the CfP for the GGOS Coordinating Office and issue this at the latest after the GGOS Stakeholder Conference in Spring 2008. Responsible: Executive Committee, Deadline: 2008-03-31.

Concerning the three new entities for Networks and Communication, Standards and Conventions, and Satellite mission, Gerhard Beutler suggested to prepare white papers detailing the mission and tasks of these entities and their role inside and outside of GGOS. The following Action Items were agreed with respect to the first two entities:

Action Item GGOS-SC10-10: Michael Pearlman will prepare a white paper, together with co-authors of his choice, on the GGOS entity for Networks and Communication, which will detail the mission, tasks, and internal and external linkage of this new GGOS entity as a basis for its implementation. Responsible: Michael Pearlman, Deadline: 2008-01-31.

Action Item GGOS-SC10-11: Hermann Drewes will prepare a white paper, together with co-authors of his choice, on the GGOS entity for Standards and Conventions, which will detail the mission, tasks, and internal and external linkage of this new GGOS entity as a basis for its implementation, taking into account that this entity will have to be based on relevant existing IAG activities and components. Responsible: Hermann Drewes, Deadline: 2008-01-31.

Concerning the third entity on satellite missions, there was considerable discussion.

Gerhard Beutler recommended that a white paper on the permanent monitoring of gravity field, sea surface, and land surface be prepared, address in particular the intercalibration, including in situ observations. Srinivas Bettadpur commented on the difficulties to integrate satellite mission teams into GGOS and doubted the necessity of such an entity. Hans-Peter Plag brought up the GGOS membership in CEOS, and reported that at the last IGOS-P meeting, CEOS members had stated clearly that GGOS should be a member of CEOS. However, Gerhard Beutler recommended to prepare a white paper first. No specific Action Item was agreed.

Markus Rothacher reiterated that the GGOS/IAG representatives to the GEO Committees no longer are members of the GGOS Steering Committee, but they are now members of the new GGOS GEO Working Group. Only the Chair of this WG is a member of the SC. Bernd Richter criticized this solution and stated that the GEO Representatives are now underrepresented in the Steering Committee. Markus Rothacher responded that they can be invited to the SC meetings with voice. Bente Lilja Bye stated a need to link this GEO WG to outreach. With respect to the chair of the WG, Bernd Richter requested that the the WG members elect their chair. Hans-Peter Plag stated that according to the ToR, WG chairs are appointed by the SC. Bente Lilja Bye proposed Hans-Peter Plag as chair for the GEO WG. Markus Rothacher voiced some uncertainty concerning the ToR, and the issue of the EG chair was postponed. This led to

Action Item GGOS-SC10-12: The EC will clarify the proceedure for appointing/electing the chair of the GEO Working Group of GGOS and ensure that a chair is appointed/elected accordingly. Responsible: Executive Committee, Deadline: 2007-09-30.

11 Call for Proposals for the GGOS Portal

Bernd Richter presented a draft Call for Proposals for the GGOS Portal (see his presentation ). In his presentation, he discussed in particular the functions, architecture, tasks, and elements of the GGOS Portal. He proposed a schedule with the CfP finalized by the authors on September 15, the review by the EC completed on October 15, 2007 and the CfP being issued on October 31. The deadline for proposal would be February 29, 2008 and proposal selection would be finsihed by March 31, 2008. After some discussion, this schedule was basically accepted All SC members are asked to provide input or comments on the draft CfP to Bernd Richter by mid September. The resulting Action Items are:

Action Item GGOS-SC10-13: Bernd Richter and Carey Noll will finalize the draft CfP for the GGOS Portal and submit it to the GGOS EC. Responsible: Bernd Richter, Deadline: 2007-09-15.

Action Item GGOS-SC10-14: The EC will review the CfP for the GGOS Portal, finalize it and distribute it widely within IAG with the deadline for submission of proposals set to February 29, 2008. Responsible: Executive Committee, Deadline: 2007-10-31.

Subsequently, Hans-Peter Plag presented a proposal for a GGOS Clearing-house for geodesy (see his presentation, pdf ). This proposal includes a Clearing-house mechanism to address international issues related to geodesy. However, due to the late hour, the proposal was not further discussed.

Outside the agenda, Michael Pearlman presented draft standards for retroreflectors for GNSS satellites (see his presentation ). He will ask the Steering Committee to endorse these standards.

Ruth Neilan showed a resolution of IAG on laser retro-reflectors on GNSS satellites (see pdf ).

12 The GEO/GGOS 2007 Workshop

Hans-Peter Plag and Markus Rothacher briefly summarized the status of the GEO/GGOS Workshop 2007, which is integrated in the International Geohazards Week (see http://geodesy.unr.edu/ggos/ggosws_2007/ ). They emphasized again the need to publicize the Workshop and to motivate submission of abstracts from both invited and other speakers. Markus Rothacher mentioned that Volker Liebig, Director of ESA agreed to speak in the opening.

13 GGOS Unified Analysis Workshop and Common Research Projects

Markus Rothacher gave a brief overview of the preparations for the Unified Analysis Workshop (see his presentation ). His presentation included a list of pending actions. Concerning the long list of potential common projects, he suggested to group these into themes or chapters. With respect to the limited participation, Harald Schuh recommended to send an official request to the IAG Services asking them to nominate representatives to the Workshop.

14 GGOS 2008 Retreat and other GGOS meetings

Due to the late hour, the GGOS 2008 Retreat (see http://geodesy.unr.edu/ggos/sc/meetings/scm13/ ) was only briefly discussed, with main focus on whether or not to combine the Retreat with a GGOS Stakeholder conference. There was no consensus on how large and wide a stakeholder conference should be. No decision was made.
