Abstract
A single software defined radio handles both AIS and ORBCOMM communications. A software defined software defined radio detects incoming signals and resolves whether they are AIS or ORBCOMM signals. The signal is directed to a processor in which an algorithm is selected in correspondence with the type of signal which has been recognized. The algorithm extracts intelligence when receiving or encodes intelligence when transmitting. The present software defined radio switches from the ORBCOMM mode to the AIS mode automatically as required in order to maintain a mandatory duty cycle in both the AIS and ORBCOMM modes as defined by regulations, and provides user configurable communications capabilities over both the AIS and ORBCOMM networks in a low-cost, integrated, hardware implementation.
