1. General Description

This chapter provides an overview of the Digi m10 Satellite Modem and its features.

1.1 Background

The ORBCOMM system is a two-way system that supports communication to and from mobi le or fixed satellite modems, also called

message or other data is first generated by an S C. From that source, the message is transmitt ed

to the nearest ORBCOMM satellite. The satel li te downlinks the message to the

Station (GES), which then transmits the message to the desired Gateway Control Center (GCC).

Within the GCC, the message is processed and f orwarded to its ultimate destination by the

Gateway Message Switching System (GMSS). T he destination may be another satellite modem,

a pager, a corporate resource management sy st em or any personal or business e-mail or Internet address.

The ORBCOMM system is available to transfer information for an end user whenever a satellite is in view of the SC. If the satellite is connected to a GES, the satellite is considered in real-time messaging mode, and the message is passed immediately through to the GCC for routing to its final destination. If the satellite is not connected to a GES, the satellite switches to a store-andforward mode to accept 200 bytes) stored on-board the satellite unt i l it connects to the SC’s host GCC through an affiliated GES.

Global Grams. Global Grams are short messag es (up to approximately

Subscriber Communicators (SCs). In most applications, a

Gateway Earth
