Objectives
The objective of this activity is to design, develop and publish a database that provides relevant statistical data for the design of tracking systems for mobile satellite terminals. The activity includes gathering the data (by measurement campaign, acquiring and/or tailoring existing data) and developing a database so that data can be accessed by antenna and system designers.
The main objective of this activity is the characterisation of the user terminal dynamics of satellite communication systems on the move. The current and future needs of the antenna manufacturing industry w.r.t. the contents and functionality of a database describing user terminal dynamics for various platforms and environments have to be accounted for.
The two primary project objectives are identified as data gathering and database development as shown in Figure 1. For the data gathering three approaches are identified by the consortium: (i) measurements, (ii) simulations based on platform independent Terrain-Profile-Data and (iii) simulations based on statistics of Terrain-Profile-Data. The database comprises the database core with its representative data & models for simulations and the web-frontend with its functionality to the user.

Challenges
The key issue of this project is the development and population of a database that contains user terminal dynamics for the environment land mobile and maritime. During the project a data gathering campaign will be performed to acquire the necessary data for the 3 approaches measurement data approach, lookup table approach and statistical model approach. A challenge in this project is the de-embedding method which would allow the simulation of the user terminal dynamics for different platforms based on the measurement the dynamics of a single platform.
Furthermore the project aims on recording statistical relevant data for various conditions especially for the maritime environment.
Plan
- Achieving a comprehensive understanding of the industry needs w.r.t. the contents and functionality of the database,
- Analysis of possible sources for a sufficiently representative amount of input data, e.g. by simulations, measurements,
- Design & integration of a measurement equipment for the direct measurement of user terminal dynamics,
- Definition of platform models and identification of their parameters that are required for the simulations based on available Terrain-Profile-Data or statistics of Terrain-Profile-Data,
- Calculation of user terminal dynamics for a platform that is not equal to the original platform during measurements and for a user defined target position,
- Measurements for the land-mobile and maritime environment
- Simulation model verification measurements for the land-mobile environment,
- Line of Sight study plan based on image processing from environment pictures,
- Database design, implementation, test, population and installation.
Current Status
The Project will start on the 01.11.2011 with the design of a questionnaire for European PAT manufactures about their needs with respect to the database developed in this project.
