Intelligent Iridium Satellite Communications Terminal

Developed and manufactured by GSE in the United States. A unique global Voice + Data + Tracking terminal that operates as a multipurpose communications hub, Internet gateway, and intelligent GPS telematics device with the ability to send and receive data, voice, and SMS, and also connect to other devices via Ethernet, through internal RS232, and WiFi. A means to keep your devices connected - ANYWHERE, on the move, on land, sea, and in the air, or in fixed sites in remote locations, or for fixed locations such as an office for assured emergency back communications, or for remote locations.

MCG-101 has been designed to provide a permanent installed reliable communications source over the Iridium Constellation for fixed sites, maritime, vehicles, and aircraft. Built with integrated GPS, providing you with optional tracking, and with pre-installed PBX. You can either plug in a simple analog phone into the analog port and make and receive calls, or you can connect to the MCG-101 WiFi and convert your Smartphone or tablet, or iPad into a satellite device to assure real-time communications.

GSE is an approved DISA Enhanced Mobile Satellite Services (EMSS) Partner. GSE's MCG-101 and GSatMicro Series products are approved to function on the DoD Gateway.

The MCG-101 accepts the Department of Defense EMSS SIM Card and is included in the EMSS Approved Product List. Contact GSE's government team at for more information.

The MCG-101 terminal comes with 2 Wi-Fi antennas, mounting brackets, and AC adapter.

Required products/services for the MCG-101 to function that you may or may not already have are as follows:

- Iridium Antenna (there is an exposed SMA connector so you can choose your desired Iridium antenna)
- Tracking Platform if tracking feature to be activated (we recommend GSE's GSatTrack universal tracking platform)
- Iridium SIM Card
- Airtime

The MCG-101 is also known as an intelligent PBX solution using Iridium to operate as a telephone, Internet portal, GPS device, and SMS terminal.

The MCG-101 was designed and built using 100% digital technology. This enables the system to provide clear, true to life audio, and eliminates any internal echo problems. For external interface portions of the system, such an analog POTS telephone, echo cancellation is performed by a hardware echo canceler.

The MCG-101 can be used in a number of scenarios for both stationary and mobile needs, from enabling remote command posts, providing redundant communications infrastructure for operations bases, to enabling voice and data communications within vehicles or vessels, regardless of proximity to standard systems and telecom towers.

How it Works
The MCG-101 is a mounted satellite terminal that contains an Iridium satellite modem to provide voice and data services to multiple connected devices, such as: traditional analog or SIP phones, smartphones, tablets, computers, and laptops. The terminal contains an internal SIM card that must be installed properly for the system to function normally. The MCG-101 also has an exposed SMA connector for attaching the required external antenna, which is procured separately in order to accommodate your specific needs, as the device is hardware agnostic. The status of the entire system can be monitored through a connected computer or through an optional DPL handset.

Remote, Global Communications for Mobile or Stationary Teams
The MCG-101 can enable a number of telecommunications capabilities in remote locations, and can also provide redundant or backup systems for emergency or disaster scenarios when traditional infrastructure becomes unavailable, unreliable, or fails completely. The terminal can support communications within a team, and can also allow users the ability to communicate with anyone via voice or data (in many forms, including SMS).

There are two primary use scenarios under which most use cases fall: Mounted Stationary Solutions and Mounted Mobile Solutions. The device functions similarly in each scenario, but caters to vastly different needs, and has different setup requirements. Mounted Stationary Solutions typically serve to outfit a command station of some kind, like a Fire Station (as in our example below), and Mounted Mobile Solutions will allow for looped communication in the field (as with our wildfire example below).

The MCG-101 in action: Emergency Disaster Relief
In remote parts of the United States, wildfires can be a common occurrence that require coordinated efforts to fight, such as that which started at Chimney Tops Campground in The Great Smoky Mountains National Park during November of 2016. Gatlinburg’s communications systems were knocked out near the beginning of the evacuation effort, leaving the alert system suspended, and the overall evacuation effort in a state of disarray. In addition, as coordination of firefighting and manual evacuation notices began to involve other departments as well as state and national resources, the communications breakdown greatly exacerbated the problems.

In a scenario such as this one, having fully equipped fire stations and ranger stations would have prevented a number of wasted manual efforts to evacuate, and likely could have even resulted in a number of lives and/or structures being saved. A fire station or ranger station equipped with MCG-101 technology would have continued to have access to phone service, as well as the ability to send and receive data from other departments and relief support agencies like the national guard, Knoxville FD, State Police, and local news organizations.

Having their fleet vehicles equipped with this technology would also have allowed for better relief efforts, as each vehicle could have communicated with central operations command with regard to progress, requests for additional support, special evacuation requests (helicopter transport or medevac), and “all clear” reporting. The value of this level of communication in scenarios such as these is immeasurable, as it can often include lives saved, historic locations or protected areas preserved, and other infrastructure like roadways and bridges remaining operative.

Additionally, if command posts and vehicles or vessels are all outfitted with the required antenna equipment, a single MCG-101 can become a portable solution as well, allowing you to dismount your stationary setup from your command post and maintain communications in a vehicle or convoy if necessary.

Feature Functionality for the MCG-101 is extensive, and includes all forms of communications transmission and receiving, enabled by a number of different connection types.

You can connect any standard analog telephone directly to the MCG-101 and start using the Iridium network. All of your calls are digitally processed for the best quality. For all satellite telephony products, we recommend the use of SatCollect to reduce costs and operate with a local phone number.

GPS Tracking
The MCG-101 contains an embedded GPS receiver for GPS tracking, with 20 channels, -159dbm sensitivity, and a 2 meter accuracy. Best of all, the GPS receiver shares a single antenna with the Iridium modem, so installation is simple.

Connecting your computer to the Internet is as simple as plugging it in. Just connect your computer and go online, and the MCG-101 will automatically connect to the Internet for you. You can also configure the MCG-101 via the ethernet port.

Connect via WiFi to enable phone calls directly from your mobile phone.

USB port for expansion to connect external peripherals.

SIM Card
The MCG-101 has an external SIM card slot which makes installing or changing the SIM card fast and simple.

Voice Capabilities
Connect any standard analog telephone or any SIP capable phone to the MCG-101 and you can start making phone calls. Digital audio processing gives you the best audio quality, and with Iridium, you can call from anywhere to anywhere in the world.

Data Capabilities
Connect to the Internet at 2.4K
Connect to RUDICS for custom applications
Short Burst Data for small messages
Ethernet for automatic dialup
Serial port for legacy modems or applications

The MCG-101 is a fully capable processing platform that can be easily configured for custom call routing, data applications, and special projects. The system features a full PBX that can run an entire office, and run custom software as well. Contact a GSE solutions consultant to coordinate communications with engineering to assist with your initiatives to develop your own solutions for complex projects. By using the MCG-101 as a standard platform, the development time is shortened, allowing you to deliver finished solutions to your customers fast.
