The objective of the SASS project was to develop a satellite based alarm and surveillance system. The system has been designed to provide connectivity between alarm and surveillance systems on one side and security centers and other receivers, for example to protect the owners of the property, on the other.
The design goals were:
In addition to the development and engineering testing of the required hardware and software components, the project conducted a 4 months field trial phase with the objective to validate the system and service performance with real end users including private security service providers and institutional organisations concerned with security tasks.
The SASS project addressed a number of issues related to the use of satellites for security applications:
The SASS system solution has the following advantages compared to terrestrial alarm and surveillance systems:
The benefits explained above do not only make the SASS system attractive for applications in remote areas, but also in regions with well developed terrestrial network infrastructure.
The SASS system concept is based on inexpensive, small and easy to install satellite terminals with built-in alarm, video, audio and data transmission capability. The terminals are linked via a geostationary satellite to a gateway station.
The gateway station provides connectivity to security centers via dedicated IP connections and to other subscribers via the Internet. The service provisioning functions are implemented in a Network Management Center. The basic architecture is shown to the right.
The key features and transmission capabilities are:
The SASS system design is compatible with DVB-RCS and other two-way satellite platforms providing dedicated IP bandwidth. The satellite bandwidth is assigned to the Satellite Terminals and the Receiving Systems by the SASS Network
The project started in January 2004. In the first 3 months, the system design and service capabilities were specified in co-operation with security service providers, security system manufacturers and certification authorities.
The development of the SASS hardware and software components and the integration with off-the-shelf parts was completed in March 2005. Engineering tests have been conducted using a satellite link emulator and real DVB-RCS satellite links. Thereafter, the system was operated during a 4 months field trial phase.
After validation of the system performance against the user needs and technical specifications, the project was completed in February 2006.
The project has been completed successfully in February 2006. The main achievements are:
The migration to commercial operation is envisaged into the following phases:
Subject to the detailed business planning the first two phases are planned to be completed until mid 2006 followed by the launch of commercial operation in the 3rd quarter 2006.
