The MoMoSat approach aims at an innovative service, that supports the secure collaboration of mobile individuals in the field by a map-based information system on wireless PDA (Personal Digital Assistant) devices.
The service uses up-to-date high quality satellite images and maps, displayed on the screen of the mobile device (notebook or tablet-pc), as a pin board on which information (i.e. text or voice notes, measurements, photos, or videos) can be pinned down interactively by the users on site. These so called 'Geonotes' can be used for collaborative communication with other users nearby as well as for documentation purposes, by uploading them to the home location via a satellite connection. The overall service is protected by a scalable security scheme that includes encryption and digital signatures.
To summarize, MoMoSat offers an extended map-based news group service. It offers new means for dependable and secure collaboration in the field.
Three key issues have been addressed:
MoMoSat will develop the prototype of a location-based SatCom service, where mobile ("nomadic") end-users in the field can securely view, manage, annotate, and communicate any kind of geo-referenced information in real-time. Based on broadband satellite connection, MoMoSat enables mobile users to work with their mobile computing devices just as they are used to work at their home office. They can equally well retrieve up-to-date information from their office, or actively upload new data to the office. In addition, this service is independent of terrestrial infrastructure, which renders this service highly relevant for relief organisations.
MoMoSat has a J2EE (Java 2 Enterprise Edition) multi tier architecture using interfaces and protocols as defined by the OpenGIS consortium. The programming language of choice was Java. Mobile client may be any computers supporting J2SE (Java 2 Standard Edition). Servers and routers will be standard PC running Linux.

The MoMoSat project started in January 2003. It went through the 4 phases until July 2004:
I. Phase: User Requirements Analysis (January '03 - March '03)
In February a document, describing the main features of the overall MoMoSat service was used as a base for discussing the individual user requirements during workshops with the potential users. The results of phase I. are outlined in the two documents: 'user requirements', and 'demonstrator definition' (BDR).
II. Phase: System Development (April '03 - August '03)
The implementation of the MoMoSat prototype, including Spatial Information Management, WLAN and SatCom, and security services was based on the preceding definition of architectural design and technical requirements (MTR).
III. Phase: Validation of Prototype (September '03 - April '04)
Beside internal validation of the systems components, the MoMoSat demonstrator was validated by the user groups against the demonstrator definition document.
IV. Phase: Commercial Feasibility Study (October '03 - June '04)
A feasibility study about the commercialisation of the MoMoSat service was developed and transferred into a roadmap to market.
The MoMoSat project was completed successfully in July 2004.
The following results have been achieved:
The final presentation of the project results was given at the "ESA Telecom Start-up Projects Workshop 1", 23rd of March 2004 at ESTEC: http://telecom.esa.int/startupworkshop1
The final review (FR) of the overall project was done at the 1st of July 2004 at ESTEC.
