Highlight Features

Pure Passive Operation No signal transmission; works as silent receiver only, zero interference to target mobile‑phone communications.
2G‑5G Full Network Support Covers GSM, WCDMA, LTE‑FDD / TDD, 5G‑SA & NSA with comprehensive cellular band support.
Sub‑Meter Location Accuracy Achieve <1m geolocation precision via multi‑unit cooperative passive sensing in open‑area conditions.
Vehicle & Man‑Pack Form Factor Two hardware variants: vehicle‑installed unit and compact backpack‑portable tactical field unit.
Multi‑Unit Collaboration Synchronize units over 433 MHz radio or IP‑network for joint target tracking and position calculation.
Integrated GIS Mapping Built‑in digital map interface, target trace playback and historical route visualization for situational awareness.
Field‑Ready Power System 3‑hour internal battery runtime; man‑pack supports hot‑swap external batteries for continuous missions.
Rugged Environmental Design ‑20°C ~ 65°C operational temperature, stable performance for harsh outdoor tactical deployments.

Technology & Collaboration

Passive Sensing & Multi‑Node Co‑Tracking. The Passive Cellular Tracker receives existing cellular down‑link signals, applying TMSI signal‑energy analysis to detect target devices without transmitting any RF signals. Multiple vehicle‑borne and man‑pack receivers exchange tracking data via 433 MHz or IP link. The system locks target BTS parameters automatically, computes geolocation cooperatively and outputs results on the embedded GIS console. Full technical specifications, band‑lists and edition details are available upon request.
