Low Volume Terminal (MIDS LVT)

Multifunctional Information Distribution System Low Volume Terminal (MIDS LVT)

The MIDS LVT is a low-cost fighter terminal with flexible, open-architecture designs. The MIDS LVT provides the critical airborne, ground, and maritime link that allows for simultaneous coordination of forces and situational awareness in battlefield operations. The reliability of the MIDS LVT is matched by its affordability and backed by our global technical support network.

The MIDS LVT is designed for a wide variety of airborne, ground, and maritime applications. The MIDS LVT consists of two major Line Replaceable Units (LRUs): the Receiver/Transmitter (R/T) and the Remote Power Supply (RPS).

MIDS LVT features

  • Secure, Jam Resistant Connectivity
  • Distributed Network
  • Control Service and NATO Interoperability
  • Long Range Coverage
  • Dual-Mode Identification (additional to IFF)
  • Accurate Relative Position Data

MIDS LVT Terminal Family

There are three families of MIDS LVT Terminals


The MIDS LVT(1) family is generally used in airborne platforms (though it may also be used on the ground). This family of terminals requires the platform provide power, cooling, control and cabling.

  Voice TACAN 1553 Ethernet Output Power Example Platforms
MIDS LVT(1) X X X Platform D 200W, 1000W* F/A-18,
MIDS LVT(4) X X Platform D 200W, 1000W* JAS-39,
MIDS LVT(5) X X Platform D 200W, 1000W* Maritime C2
MIDS LVT(6)   X X Platform D 200W AC-130, F-16
MIDS LVT(7)     X Platform D 200W B-2

* requires additional hardware (HPAG)


The MIDS LVT(2) family is generally used in ground platforms. This family of terminals includes power, cooling, control, and cabling.  The LVT(2) family does not implement TACAN.

  Voice TACAN X.25 Ethernet Output Power Example Platforms
MIDS LVT(2)     X Platform J 200W Army Ground
MIDS LVT(11) X   X Platform J 200W Air Force Ground


The MIDS LVT(3), also known as the MIDS FDL, is a specially designed terminal used by the U.S. Air Force F-15s. This is a 50 Watt terminal that controls the onboard TACAN, but does not contain a Voice or TACAN within the terminal. The MIDS FDL has been recently tested for ground application.

MIDS LVT frequently asked questions

The MIDS LVT provides two secure voice channels, supporting both 2.4 Kbps and 16 Kbps voice.
A Block Cycle Upgrade is an upgrade to the government furnished CORE and TIO software that is loaded into the MIDS LVTs.These software releases are controlled by the MIDS PO. A Block Upgrade is an upgrade made either to software or hardware that is under the control of the Vendor.
A FIM is a Functional Input Message used for Host-to-Terminal communication transmission on the host bus. FOM is a Functional Output Message used for Terminal-to-Host communication transmission on the host bus.
The Support Port is an Ethernet interface of the LVTs that provides access to detailed performance data, much of which is not available on the normal Host interface. The Support Port can also be used for software loading.
Tactical Air Navigation (TACAN) is a military navigation system. It provides the user with distance and bearing and operates with a channel spacing of 1 MHz in the frequency band 962 – 1213 MHz.
Yes. The MIDS LVT requires the installation of three 3.0 Volt Lithium-Manganese Dioxide Non-Rechargeable Batteries
  • Ultralife Part Number: U10025 (replaces U2550HCES-F95)
  • NSN: 6135-01-545-6582
  • Nominal battery life is 6 – 8 months
  • 10-year shelf life
  • Storage and disposal in accordance with local HAZMAT procedures
The Ultralife batteries CANNOT be substituted with standard C Cell batteries.
The batteries serve two purposes. The first is to retain the Crypto keys when the MIDS terminal is in the "Stand-by" mode.
The second is to retain Crypto keys and Link 16 data when the terminal is in the "On" position during power interruptions.
All 3 cells MUST be replaced at the same time. Follow your local maintenance instructions for proper removal and installation of the batteries.
Note: The wedgelocks for the batteries and battery compartment cover have specific torque requirements.
A notch filter is used to pass a majority of frequencies unaltered, but attenuate those in a specific range to very low levels.
Link 16 uses internal notch filters to attenuate the 1030 / 1090 frequency bands which are used for IFF.
External notch filters are used for additional protection from transmission in unauthorized frequencies.
