The TW Ghost 881 is TrellisWare's answer to the requirement of bringing TSM mesh network capability to small-format UAS platforms: less than 50 grams, low power consumption, and the full TSM-X protocol to transparently integrate into the same IP network operating on the ground. With the Ghost 881 installed on a small-format UAS, the drone is not just an observation platform — it is an active node of the tactical mesh network that retransmits traffic between ground teams separated by terrain obstacles.

In urban combat operations, a UAS with Ghost 881 flying at 50-100 meters altitude acts as a temporary aerial relay: teams without direct line of sight between them (separated by buildings, walls, or rugged terrain) maintain continuous IP connectivity through the airborne node. The relay is transparent to applications: ATAK systems, video streams, and PTT voice communications don't need to know that traffic passes through the UAS — the TSM-X network manages routing automatically.

Key features

< 50 g: the lightest airborne TSM node in the Ghost family
Transparent aerial relay: ground teams need no configuration — TSM-X routes automatically
Same TSM-X waveform as TW-950: full interoperability without gateways or protocol adapters
Extends network to 3D: UAS as mesh node overcomes line-of-sight obstacles in urban combat
AES-256 FIPS 140-2: NSA-grade encryption in under 50 grams

Applications

01Urban combat aerial relay: overcome building obstacles to maintain platoon IP network

02Simultaneous ISR + relay: UAS observes and retransmits tactical data in the same mission

03Mountain terrain operations: aerial relay where ground relay cannot reach

04Search and rescue: drone extends communications network to collapse zone without infrastructure

05Advanced reconnaissance: UAS on TSM network shares GPS position and real-time video
