IMPROVED SWaP
The DTCS mission module, part of the AssuredReach™ family of products, is
a small-form-factor channel expansion solution that provides critical SATCOM over a global network. Using the DTCS and L3Harris’ enhanced short burst data (eSBD) capability, this solution provides beyond-line-of-sight (BLOS) voice and data while on the move, from anywhere in the world.
The DTCS mission module enables users of the L3Harris AN/PRC-163 multi-channel handheld radio the advantage of communications in any combination of SATCOM, mobile ad hoc network (MANET) or UHF/VHF line-of-sight (LOS). This added capability delivers high assurance voice and data SATCOM on the move (SOTM) in a combined, small form factor solution that reduces the size, weight and power (SWaP) burden on the warfighter.
The DTCS mission module can be tethered to or mounted on the AN/PRC-163 to enable secure SOTM and eliminate the need for two radios. Control of the mission module is accomplished using the AN/PRC-163 control panel.
In addition, existing RO® BLOS radio users can now carry just one radio to enable both SATCOM and secure UHF/VHF line-of-sight communications by utilizing the AN/ PRC-163 and the DTCS mission module. The DTCS mission module receives its power from the existing AN/PRC-163 battery eliminating the need for two types of batteries.
