Abstract
A subscriber communicator module and an external data storage device perform the functions of receiving RF communication signals, converting the received RF signals to received digital output samples and converting digital input samples to RF communication signals for transmission; transforming the digital output samples to digital output data and transforming digital input data to the digital input samples; and processing the digital data in accordance with ORBCOMM data protocols. The module includes at least an RF section for performing the receiving and conversion functions. The external data storage device contains software for implementing performance of the transformation functions and/or the data processing function by one or more sections of the subscriber communicator that are not included in the module. Preferably, the module also includes a transformation section and a control processing section, in which the only communication activities provided in accordance with ORBCOMM data protocols are reports and/or user commands.
