As has been pointed out in recent communications from the GEOIDE NCE Research Management Committee, the network as a whole needs to do a better job of "networking" within and across projects. Because GPS is such a ubiquitous technology and features in a number of the GEOIDE NCE projects, it is incumbent on GEOIDE GPS researchers in particular to enhance their networking activities. In fact, we need only recall the first-listed objective of the GEOIDE NCE: "To better exploit Canadian Geomatics infrastructures such as the new GPS infrastructure ..."

In order to begin the process of improving networking on GPS-related issues within the GEOIDE NCE, a GPS "round table" meeting was held during the GEOIDE NCE annual meeting in Calgary. Representatives from each of the five GEOIDE projects with a significant GPS component were invited to participate. The meeting was well attended with 16 representative from academia, the government, and the private sector (see attachment).

Representative from each of the projects were asked to introduce their project, concentrating on the GPS aspects, and briefly summarizing the project accomplishments to date and to suggest possible topics and avenues for collaboration between projects (see attachment). While all of the projects relate to kinematic positioning, the dynamics of the applications vary widely, with platform speeds ranging from millimetres and centimetres per year (geodynamics) through a few kilometres per hour (ships) and tens of kilometres per hour (land vehicles) to hundreds of kilometres per hour (aircraft). Nevertheless all applications need to process range data to extract position and other information and so can share error modelling and algorithmic approaches to a certain degree. For example, modelling tropospheric and ionospheric propagation delays is common to all techniques and so all GPS-related projects can share from advances in these areas made within the GEOIDE NCE.

It is hoped that this first effort in networking across the GPS-related projects has made project investigators more knowledgeable about what is going on in other projects, has made them aware of common problems and opportunities for cross-project collaboration, and will lead to specific investigator-to-investigator contacts.

It was felt that cross-project meetings such as this one should be a regular feature of GEOIDE NCE annual meetings.
