Sentry Post: Man-Portable Drone Detection System
On today’s battlefields, small patrols and dismounted units are often the most vulnerable. At night, when visibility is low, or in contested terrain where threats can appear without warning, maintaining constant vigilance is both exhausting and impractical. The Discovair G2+ from Squarehead transforms this challenge, establishing an immediate acoustic safe zone that provides 360° surveillance and early warning against drone threats.
With only a compact sensor, a small battery pack, and a device running ATAK or Glipe, a patrol instantly gains a reliable detection perimeter. Soldiers are alerted the moment a drone is detected – with directional awareness – enabling them to focus on their mission until a genuine danger arises.
Force Protection Through Acoustic Awareness
Sentry Post is designed for small units, from a single soldier to platoon size. It provides:
Catch-all acoustic drone detection with 360° coverage from a single portable sensor
Zero-configuration deployment – ready in seconds with no setup required
Lightweight, battery-powered design for rapid deployment and redeployment
Passive operation – silent, emission-free, and undetectable to the adversary
Multi-purpose capability – with optional detection of small arms fire, indirect fire, etc.
By issuing immediate alerts, the system acts as a force multiplier, giving soldiers time to engage threats before they become critical.
Uninterrupted Protection
Traditional surveillance requires constant visual observation – a draining task that can limit a unit’s effectiveness. Sentry Post removes this burden. By continuously listening to the environment, the system allows soldiers to remain human: resting, observing, and conducting their tasks, while still maintaining 24/7 protection.
This balance between operational readiness and human endurance is what makes Sentry Post transformative. It creates a sentry that never tires, ensuring patrols are always covered, even when their eyes are elsewhere.
Deployment & Flexibility
Sentry Post is built for field conditions:
Man-portable – carried by a single operator or distributed across a team.
Standalone – no supporting infrastructure required.
Seamless integration – with ATAK and Glipe
This flexibility ensures Sentry Post can be adapted to a wide range of missions, from reconnaissance to securing temporary positions.
Always Ready, Always Protected
By transforming any patrol into a secure, always-alert sentry, Discovair G2+ ensures soldiers are never caught off guard. Whether moving through contested terrain, securing a temporary position, or simply resting between tasks, units gain the confidence of knowing their perimeter is continuously protected. In this way, Sentry Post doesn’t just enhance protection – it restores focus, resilience, and control to those on the ground.
-
Sentry Post is not a separate product but a use case where the Discovair G2+ is deployed as a man-portable drone detection system. It turns a patrol or temporary position into a constantly alert sentry, extending protection without requiring extra manpower.
-
With just a sensor, a small battery, and a device running ATAK or Glipe, soldiers gain instant 360° acoustic surveillance. This setup provides early warning of drones and other threats, giving small units the same protective awareness usually reserved for larger bases.
-
Acoustic detection is passive, silent, and immune to jamming. It works day or night, in dense terrain or open areas, and without line-of-sight. Combined with the lightweight, man-portable design of the Discovair G2+, it is easy to carry and deploy, making it perfectly suited for patrols and small teams operating in unpredictable environments.
-
Instead of keeping soldiers on constant visual watch, the system listens continuously and only issues alerts when a threat is present. This reduces fatigue, lets units focus on their mission, and ensures they are never caught off guard.
-
It is ideal for patrols on foot, reconnaissance teams, and units holding temporary positions. It seamlessly integrates with ATAK and Glipe making it a flexible solution for contested or unpredictable environments.
