Abstract
A satellite based communication system in a low-earth-orbit (LEO) has multiple beams and FDM channels within each beam for voice/data communication between user terminals and multiple gateways. The satellite based communication system has two links for duplex communication, i.e., a forward link between the gateway and the user terminals through the satellites and a return link between the user terminals and the gateway through the satellites. Low volume telemetry data from remotely located assets, such as liquid petroleum gas tanks, water tanks, oil storage tanks, rail cars is gathered, processed, and transferred to a customer over an Internet link. A remote telemetry unit with a sensor and a simplex transmitting unit transmits remote telemetry data. A gateway receives data and directs the data to a gateway applique for demodulating and decoding. Resulting messages are sent to the customer via a back office over an Internet connection.
