Objectives

The SC1000 Field Terminal project has the objective to improve the SDS-Mk2 satellite based narrowband data services for mobile and static applications. A new terminal is built with lower power consumption, remote configuration and monitoring, L- and S-band support and extra features. The base station and over the air protocol are redesigned to support the new SC1000 terminal.

The SC1000 Field terminal collects data from external sensors and the GPS satellites. The data is formatted and send to the Land Earth Station (L.E.S.) through a leased L- or S-band satellite link.

In the L.E.S. all data packages are decoded, filtered and transferred to the Datacenter.

The Datacenter stores the data packages in a central database and forwards data to the billing servers, back office applications and customer defined destinations.

Challenges

The key issues of the previous generation of terminals were the terminal cost, the power consumption and the remote accessibility. All of the issues are addressed in the SC1000 project as reflected by the features of the new terminal/system.

Benefits

The cost of the terminal and the operational costs are lower than the previous generation terminal and system. That together with the extra features and lower power consumption opens the path to additional markets for the product.
