  • For use in land vehicles

  • Custom cable for mobile radios not included

  • Uses smart messaging (see more below)

  • Requires a monthly PTT airtime plan

Key Features:

  • Basic cross band to conventional radios (PTT/COR) signaling
  • Supports intelligent handset (H2) with PTT functionality; ability to display and change talk-groups; show signal strength and connection status
  • Analogue control head supports handset, external speaker, volume control, on/off switch, built in power amplifier
  • iMatrix XB is not simply a bridge but is also an active Iridium PTT device that supplies Iridium PTT communications for the land vehicle occupants.
  • The iMatrix XB can support location tracking for the vehicle (additional costs apply). The tracking only records the positions of Iridium PTT devices when they become the talker in a Talk Group. 

Reliable Coverage:  You can depend on the Iridium satellite communications to provide reliable, global coverage no matter where you are.  Iridium PTT eliminates the need for reliance on land-based radio towers, landlines and fiber optic lines that can be damaged in regional disasters such as hurricanes and earthquakes.  Satellite communication systems ride above storms providing communication when other communication systems are down.

Smart Messaging: The iMatrix XB employs Smart Messaging. Voice messages are intelligently managed.  For example, should two users at different locations push to talk at the same time, one message will be delayed until the other message has been transmitted.  Then Smart Messaging will transmit the delayed message.  Messages are never lost.  A user in a moving vehicle may be communicating with dispatch.  If the land vehicle carrying the iMatrix XB enters a tunnel while the user is speaking, Smart Messaging will detect the connection to the satellite network if it has been lost.  Upon the vehicle exiting the tunnel and re-establishing connection with the network, Smart Messaging will transmit the users message from the beginning. Transmitting the full message ensures the recipient retains the message context.

Interoperability: The iMatrix XB may be used as an interoperability gateway.  Sophisticated interfaces enable integration with a wide range of mobile radios. User organizations may interconnect their radios with the iMatrix XB and share their talk groups or channels with other organizations.  Interoperability made easy!

Multiple Talk Groups: Talk groups / communications channels are easily selectable from the ergonomic handset.

Control Head: A Control Head option featuring a powerful amplifier and external speaker is available. The control head provides for convenient mounting in the vehicle cabin and may include provision for disabling the satellite backhaul if desired.

Handset with Display:  A slim handset with integrated display and keypad is available. The handset offers the user a degree of privacy while making a call. The display on the handset provides status information relating to the satellite connection, the selected talk group/communication channel as well as providing a means for the user to adjust the settings to suit their specific preferences. The handset enables the selection of talk groups/communications channels.

Installation: The iMatrix XB features a compact rugged design with four external mounting points. Interface points are fitted with locking screws or snap-lock connectors.  The iMatrix XB incorporates a regulated power supply to condition the input power and remove transients and noise. In addition it ensures continued, uninterrupted operation even though the input power may drop to as low as 9.5 volts.

On-the-Fly Web-Based Administrative Controls:  Each subscriber organization has access to a PTT Command Center web portal that allows the subscriber organization's administrator to quickly and easily adjust the boundaries of any Talk Group by simply placing circles, rectangles, and other controls on a map. A Talk Group can even be formed from non-contiguous areas in different states or different countries.  The administrator can adjust the boundaries of a Talk Group on the fly and can control which Iridium PTT handsets have membership in each Talk Group.  The system is easy to use and easy to administrate.

Iridium Push-to-Talk Airtime Plans:  Postpaid telephony-mode services such as phone calls and texting are billed monthly. Call detail records are provided. Unlimited push-to-talk communications are included with the low monthly fee. For more airtime information, click here.

Talk Group Options: The smallest Talk Group that Iridium offers has a generous coverage area about the size of the state of Indiana.  Larger talk group coverage areas are available if needed (for additional charge).  Complex talk group borders can be configured by the user on-the-fly using the PTT Command Center web portal.  For more  information, click here.

* Notes: This product requires custom engineering. A custom wiring harness is required to connect the iMatrix to a land mobile radio. There is a $1000 integration fee for engineering time to build a custom wiring harness. A different custom wiring harness will be required for each type of mobile radio used in concert with the iMatrix. There is a version of iMatrix (for additional cost) that can be used with MSAT equipment. Outfitter Satellite has demonstration Iridium PTT equipment available for short term proof-of-application demonstrations, including the ICOM IC-SAT100, Extreme PTT, and a portable iMatrix XB kit.
