Embedded National Tactical Receiver Transmit Variant (ENTR TX)

Compact, reliable receiver with transmit capabilities ENTR TX is the latest solution in L3Harris’ long line of ultra high frequency Integrated Broadcast Service (IBS) receivers with an additional transmit capability. It features low size, weight and power (SWaP) in a form factor that is well-suited to any platform.

Actionable Intelligence for the Mobile Warfighter

ENTR Tx is a lightweight, low-cost and reliable transceiver that enables producers to transmit information across the IBS while receiving messages from the Common Interactive Broadcast (CIB) and IBS. With the additional transmit capability, warfighters can provide near real-time situational awareness.

ENTR Tx receives IBS UHF satcom signals via direct-to-digital radio frequency (RF) processing and provides a transmit function for those approved producers on the IBS. Like the ENTR V4, the ENTR Tx receiver supports up to six IBS channels without the need for costly, sensitive RF components. The channel scheme can be reconfigured dynamically without interfering with operations. With the added transmit feature, the same unit can broadcast on a prescribed UHF satcom channel.

Offering Convenience and Flexibility

ENTR Tx has been rigorously tested to reliably support land, air and sea operations. The device is designed to interface with any host platform that has an Ethernet port, including mobile servers, laptops and tablets. The receiver can be powered by a flexible 24 to 32 volt direct current (VDC) input, which allows users to leverage a variety of power sources, from a battery pack to aircraft power. With in-radio processing, the ENTR Tx only needs to plug into a display so that warfighters can view the IBS data. Warfighters can also push organic data through the same Ethernet port to the broadcast side of the IBS.

The ENTR Tx natively hosts the tactical receive segment (TRS) software which will feed any tactical data processor that TRS supports. The interface software is compatible with all the mainstream message processing and control software. Alternatively, the ENTR Tx can connect to an external TRS (hosted on any Windows™ 10 PC) via Ethernet.

Automatic Updates for Uninterrupted Use

The software-programmable ENTR Tx will facilitate changes or improvements by easily upgrading the firmware or software. Upgrades and new releases can be made automatically and in the field for continuous use and offers lower maintenance costs throughout the life of the ENTR Tx.

The ENTR Tx is NSA Type 1 and TEMPEST certified and contains reprogrammable anti-tamper. Crypto key loading is provided by the ENTR Tx’s automated key loading and handling capability.
