TSAT working principle

TSAT will work with any commercial satellite having Ku- or C-band transponders.

Since most of the earths landmass has excellent satellite coverage, TSAT can be deployed globally.
TSAT is generally subject to licensing like most RF communications solution, but Government's are increasingly liberalizing
the use of satellite communication and adopting 'open sky' policies to promote social and economic development.

The diagram above illustrate how the various components is the system interact. Data from the SCADA-FEP (the application) travels up to the satellite where it is amplified and then broadcast down to all the remote terminals in the network. There is a 0.25s delay from when the data leaves the HUB, and is received by the remote terminals. This propagation delay is due to the time it takes for the signal to travel through the atmosphere, some 36000km up to the satellite, then down again.  When the remote terminals receive data, they will pass it immediately on to the connected RTU.

When the remote terminals receive data from the RTU's, they will transmit this back to the HUB in accordance with a defined acces scheme to optimize the response. When the data travels back up to the satellite, then down again to the HUB, there will be another 0.25s delay. When the data is received by the HUB it will then be transferred to the SCADA-FEP. The data transmission via TSAT is totally transparent to the application.
