Iridium RUDICS Service

Product ID: svc-ir-rudics
Overview

Iridium Router based Unrestricted Digital Interworking Connectivity Solution (RUDICS) is an enhanced Gateway termination/origination capability for circuit switched data calls across the Iridium satellite network. RUDICS is designed to be incorporated into an integrated data solution. Integrated data solutions are applications such as remote asset monitoring, control, and data file transfer. Often these applications are designed to support hundreds or thousands of remote units. RUDICS is designed to take advantage of the global nature of the Iridium communications system and combine that with a modern digital connection between the Iridium Gateway and a centralized application server or Host Application.

RUDICS Service Applications

Typical applications include:

  • Email – Sending and receiving of email using custom applications software
  • FTP (File Transfer Protocol) for transferring data files.
  • Periodic data reporting by remote sensors
  • Polling of remote units to collect data
  • Control of remote equipment

Note that RUDICS is typically best suited for applications that:

  • Deploy more than 500 units, which report to a central host application OR
  • Use>1000 bytes and greater than 3 times per day

Benefits

There are several key benefits to using RUDICS as part of a data solution as compared to using Dial-Up over the PSTN, mobile-to-mobile data, or Direct Internet. These benefits are summarized below:

  • Elimination of analog modem training time. This time is billable overhead, which results in a higher “effective” cost per kbyte on smaller data transmissions.
  • Increased connection quality, reliability, and maximum raw data throughput.
  • Protocol independence. No requirement to have a PC operating system and no requirement for TCP/IP.
  • Support for both Mobile Originated (MO) and Mobile Terminated (MT) calls.
  • MT calls rated the same as MO calls. This is not the case for calls placed via the PSTN.

How it Works

Remote applications use AT Commands to control any circuit switched data capable Iridium Subscriber Unit (ISU). The remote application dials a customer specific Iridium number, which connects the call through the Siemens D900 switch, to the RUDICS server. This customer specific number is assigned and provisioned by Iridium. Each ISU is authenticated using Calling Line Identification for the RUDICS customer specific number that it dialed. Once authenticated the call is routed over the terrestrial connection to a pre-configured Internet Protocol (IP) address and Port.

The Host application can make a Mobile Terminated call by opening a Telnet session to the RUDICS server. Once authenticated, a series of AT Commands are used to connect to the remote ISU and establish a circuit switched data call.

Connectivity between the Iridium Gateway and the Host Application can be by a variety of methods, including Internet, Virtual Private Network and Leased Line.

Additionally, the RUDICS application offers the capability for multi-link Point to Point Protocol (PPP). This allows multiple ISU’s to be used to send data simultaneously and the data can be delivered in an N x 2400 bps PPP connection.

RUDICS has a number of advantages over other methods of originating and terminating Circuit Switched Data calls on Iridium.
