Editing Iridium Communications (section)

=== Standalone transceiver units ===
These can be used for data-logging applications in remote areas (as in [[data collection satellite]]s). Some types of [[buoy]]s, such as those used for the [[tsunami warning system]], use Iridium satellites to communicate with their base. The remote device is programmed to call or send short [[Burst transmission|burst]] data (SBD) messages to the base at specified intervals, or it can be set to accept calls in order for it to offload its collected data.

The following transceivers have been released over the years:

*Iridium Core 9523 – Similar to the 9522B, a modular transceiver released in 2012
*Iridium 9522B&nbsp;– A transceiver released in late 2008, is smaller than the 9522A and has similar features. It also supports Circuit-Switched Data (CSD), not just SBD.
*Iridium 9522A&nbsp;– Based on the 9522, some variants have built in GPS and autonomous reporting functions. Supports SBD.
*Motorola 9522&nbsp;– Last Motorola transceiver, supports outgoing SMS but no SBD.
*Motorola 9520&nbsp;– Original transceiver module, does not support outgoing SMS or SBD. Designed for use in vehicles with accompanying handset<ref>{{cite web |url=http://www.outfittersatellite.com/iridium_9520.htm |title=Iridium Satellite Phones For Sale |website=Outfittersatellite.com |access-date=2016-02-24 |url-status=dead |archive-url=https://web.archive.org/web/20120416045951/http://www.outfittersatellite.com/iridium_9520.htm |archive-date=2012-04-16 }}</ref>

==== Short burst data modems ====
These devices support only SBD for [[Internet of things]] (IoT) services and do not use a SIM card.

*Iridium 9601&nbsp;– Supports only SBD, several [[tracking device]]s and other products have been built around this modem. It was an Iridium manufactured product designed as an OEM module for integration into applications that only use the Iridium Short Burst Data Service. Short Burst Data applications are supported through an RS-232 interface. Examples of these applications include maritime vessel tracking or automatic vehicle tracking.<ref>{{cite web|url=http://www.iridium.com/products/iridium9601.aspx |access-date=November 19, 2013 |url-status=dead |archive-url=https://web.archive.org/web/20131203011010/http://www.iridium.com/products/iridium9601.aspx |title= Iridium 9601-Overview|archive-date=December 3, 2013 }}</ref>
