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.

Claims

1. A subscriber communicator module that performs the function 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 to provide a plurality of communication activities, the module comprising;

an RF section for performing the receiving and conversion functions; and

a transformation section coupled to the RF section for performing the transformation functions; and

a control processing section coupled to the transformation section for performing the data processing function in accordance with a limited portion of the ORBCOMM protocols;

wherein the communication activities provided by the control processing section in accordance with the limited portion of the ORBCOMM data protocols includes at least reports and user commands; and

a serial data interface; and

means for enabling the serial data interface to be selectively coupled to either (a) the control processing section for use as a user interface or (b) the transformation section for enabling the transformation section to be coupled to an external data processing device that is adapted for performing the processing function in accordance with a more extensive portion of the ORBCOMM data protocols that includes the limited portion and an additional portion of the ORBCOMM data protocols.

2. A module according to claim 1, in combination with an external data storage device that contains software for implementing performance of the data processing function by said external data processing device.
