1. Tiantong/Beidou Dual-Mode Satellite Rugged Tablet
The main equipment in this drill is the industrial-grade rugged smart tablet terminal GETAC F120, which integrates China's independently controllable Tiantong-1 satellite communication and Beidou navigation and positioning dual modules, featuring the following hardcore capabilities:
Extreme Protection: Certified with IP66 dust and water resistance, capable of withstanding immersion in deep water without damage; military-grade drop resistance, able to endure drops from a height of 1.8 meters; operates in an ultra-wide temperature range of -29°C to 63°C, fearless of heavy rain, mud, extreme heat, and severe cold.
Omnidirectional Communication: When ground public networks are down, it automatically and seamlessly switches to Tiantong satellite voice communication and Beidou short message communication, achieving coverage without blind spots across China and surrounding sea areas.
Efficient Operation: Equipped with a high-brightness sunlight-readable screen, clearly visible under outdoor strong light; rich interface options, allowing direct connection to various professional devices such as hydrological monitoring equipment and drone video transmitters; long battery life, ensuring continuous field operation.
2. Coordinated Combat System
Working in coordination with Ku-band high-throughput satellite portable stations, tethered drone airborne base stations, and other equipment, it quickly builds an emergency communication network, forming a three-tier command chain of "individual soldier — front line — rear command."
Scenario 1: "Three Outages" Extreme Situation – Individual Soldier's Lifeline
Core Challenge: Floodwaters destroy base stations and fiber optic cables, power is cut off, and rescue teams instantly fall into an "information island." Traditional walkie-talkies, with a communication range of only a few hundred meters, become completely ineffective.
Practical Performance: Rescue team members carrying the GETAC F120 rugged tablet operate in extreme conditions such as wading through water, climbing, and traversing landslide areas. Throughout the mission, the device remains waterproof, stays powered on, and maintains a stable signal. Relying on the Tiantong satellite and Beidou dual-mode system, it enables real-time transmission of text, images, precise location data, and on-site video. It also automatically reports key data such as team member coordinates, water levels, and hazard information every three minutes. The rear command center maintains full visibility, full control, and uninterrupted contact with the front-line situation, completely breaking the "information island" and providing first-hand data for rescue decision-making.
Scenario 2: Hydrological Emergency Monitoring – Real-Time Data Upload
Core Challenge: Rapidly rising river levels and turbulent currents make manual flow measurement extremely dangerous and data collection lag behind, failing to provide precise support for decisions such as flood diversion and levee construction.
Practical Performance: The GETAC F120 rugged tablet serves as a mobile monitoring hub. Through dedicated interfaces, it directly connects to devices such as radar water level gauges, ADCP current meters, and drone flow measurement systems, enabling local real-time acquisition of precise data including water levels, flow velocity, and discharge volume. All monitoring data is transmitted via satellite link to the provincial hydrological bureau command center within seconds, without waiting for ground network restoration. The system automatically generates water level heat maps and flood evolution curves, providing a basis for scientific analysis and precise decision-making.
Drill Results: Hydrological monitoring efficiency increased by 70%, with data measurement error controlled within ±3 cm.
Scenario 3: Front-Line Command and Dispatch – Mobile Command Hub
Core Challenge: Fixed command posts are flooded, roads are cut off, command vehicles cannot enter, traditional command models collapse, leading to delayed decisions and chaotic coordination.
Practical Performance: Commanders holding the GETAC F120 rugged tablet can, even while wading through water or traversing on foot under dynamic conditions, access multi-dimensional information in real time, including panoramic images of the disaster area, drone aerial footage, the distribution of rescue team members, and hydrological monitoring data. The tablet enables integrated voice and video dispatching, allowing precise point-to-point commands for evacuation, breach closure, search and rescue, and other operations. Furthermore, it facilitates cross-departmental data sharing, resource coordination, and collaborative operations among emergency response, firefighting, water resources, electric power, and other agencies, completely breaking down information barriers and establishing an efficient, streamlined, and visualized mobile command system.
