A military-grade system that enables small craft (SC) to navigate, operate, and communicate securely with a group that can include a mothership.

OSI’s T-ACT kit for each boat provides crew members with the ability to navigate using a version of ECPINS optimized for use on a small craft. Under way, the crew is able to monitor the position of other boats, locate the mothership, track the bearing and range of a Contact of Interest (COI), share data such as soundings, and communicate with other boats via encrypted text messages. By equipping the boat with a digital radar and the ECPINS-SC Radar Control software module, this helps to add an extra dimension to the coxswain’s situational awareness.

Its ECPINS operator can monitor the location of the boats where the mothership leads the group without leaving the familiarity of an ECPINS workstation. The ECPINS operator has command and control to share contacts with any of the boats, designate a Contact of Interest (COI) for a boat too close, exchange text messages, and send data such as contacts, routes, chart objects and areas – all encrypted within the group.


• Plots all vessels within the secure group
• Displays AIS, operator-created, and shared contacts
• Works with Saab R5S/R6S secure AIS devices
• Transfer of encrypted communications and data within the group
• VHF-based line of sight communication, can be connected to a Beyond-Line-of-Sight (BLOS)/Over-the-Horizon (OTH) system.
• T-ACT kit is weatherproof, shock resistant, and of small form factor
• Optional radar control interface for a SIMRAD digital radar


• Each boat: T-ACT kit, which includes a secure AIS (Saab R5+), GPS, and computer running ECPINS-SC 6
• Mothership/HQ: secure AIS (Saab R5+), ECPINS 6 plus the Small Craft Ops software module
