The AMT 83L Modem Series continues the line of the first worldwide satellite modem (AMT-73L), to be certified with MIL-STD-188-165A by DISA.  The AMT-73L was designed to fulfil two way satellite communication requirements in Defense Satellite Communications Systems (DSCS). Several thousands of these modems were deployed in the field on tactical terminals.


AMT 83L Modem Series – Advanced Military Grade Satellite Modem

Based on the Advantech Wireless “Software Defined Radio” architecture, the AMT-83L satellite modem series adds a number of advanced features to the DISA certified AMT-73L series modems. Among these new features there are:

  • DVB-S2 with LDPC Coding and Adaptive Coding and Modulation (ACM)
  • IP data interface
  • GSE encapsulation
  • Direct Sequence Spread Spectrum (DSSS) spreading
  • AES 128/256 Encryption

All these new features transform the AMT-83L series modem into a powerful satellite communication tool. The modem can now address the new advanced and efficient DVB-S2 modulation and error corrections codes, via full-fledged IP traffic, with built in router, and GSE encapsulation, as well as the SATCOM-on-the-move (SOTM) mobility applications due to the DSSS spreading features.

With built in AES 128/256 Encryption, the modem allows for secure communication links, unhindered by eavesdropping.

The standard data interface is the IP Gateway, with optional EIA530/499, HSSI, ASI.

The IP Gateway data interface is a miniaturized fully fledged IP router designed to give ease of use, support for a wide range of protocols, security and QoS.

1:1 Redundancy switching is built into the unit as an optional feature.  With the addition of an interconnecting control cable between the modems and the switch unit for IF and data interfaces complete redundancy is achieved.

Monitoring and Control is performed via Ethernet using HTTP, Telnet or SNMP.
