Product positioning and technical core
Dingjian Tiantong satellite phone is a satellite communication equipment independently developed by China. It relies on the Tiantong-1 satellite system (covering China and surrounding areas, the Middle East, Africa and the Pacific/Indian Ocean) and Beidou short message technology to achieve dual-mode seamless switching of "satellite + ground cellular network". Its core value lies in autonomy and controllability - using domestic satellite systems to get rid of dependence on foreign countries and ensuring safety - ensuring the security of data transmission through national secret algorithm encryption, and supporting Hongmeng system customization and secondary development to meet the needs of multiple scenarios such as government affairs, border defense, and emergency response.

Technological breakthroughs and functional highlights

Multi-mode converged communications: It integrates satellite voice calls, Beidou short messages (1,200 words + location coordinates can be sent at a time), 4G/5G cellular network and shortwave/ultra-shortwave radio stations, and automatically switches to satellite mode when the ground base station is damaged to ensure "uninterrupted communication".

High-precision positioning and tracking: Combining Beidou/GPS dual-mode positioning and RTK technology, it achieves centimeter-level positioning accuracy (error in open environment: 1-3 meters), supports trajectory tracking, electronic fences and anti-interference fast positioning (TTFF ≤ 5 seconds), and is suitable for border patrol, geological exploration and other scenarios.

Adaptability to extreme environments: IP68 dustproof and waterproof, operating temperature -40℃ to 80℃, anti-fall and explosion-proof design (ATEX/IECEx certified), equipped with a 5250mAh large-capacity battery, with a battery life of more than 10 hours in satellite communication mode and a standby time of 72 hours, meeting the needs of harsh environments such as polar regions, deserts, and chemical plants.

One-click SOS and smart rescue: Press the SOS button for 2 seconds to automatically send a distress signal and location information, supporting two-way calls. The rescue platform can locate and coordinate resources in real time, realizing a closed loop of "help-location-rescue".

Border patrol application scenarios

border security control: In remote areas such as Ali in Tibet and Hotan in Xinjiang, the border defense forces are supported in real-time monitoring of the status of boundary markers and barbed wire fences, early warning of cross-border behavior through "electronic fences", and strengthening control of key areas. For example, when border guards are attacked by stowaways or wild animals, they can send "SOS+ coordinates" to the rescue platform through Beidou short messages to avoid exposing their location.

Emergency rescue and disaster response: In disasters such as earthquakes, floods, and landslides, the equipment can quickly return high-precision terrain data in the disaster area to assist rescue decisions.

Special industry protection: In explosive environments such as oil and gas fields and chemical plants, explosion-proof design ensures equipment safety ； Provide stable communication support during polar scientific expeditions and ocean voyages.

Strategic value and social benefit

Independent and controllable strategic support: The Tiantong satellite system was independently developed by my country. Three in-orbit satellites form a global coverage network, eliminating dependence on foreign satellite systems and ensuring secure and controllable communications, in line with the national strategy of "self-reliance and self-reliance through science and technology."

Economical and scalable: Compared with traditional satellite phones, the equipment cost is reduced by 60%. It supports customized Hongmeng system and secondary development. It is suitable for many scenarios such as government emergency, border patrol, tourism and adventure, and provides one-stop communication equipment application solutions.

Full-process closed-loop guarantee: Through the whole chain design of "early warning-positioning-rescue-disposal", combined with Beidou positioning and satellite communications, closed-loop management from risk monitoring, rapid response to resource allocation is realized, significantly improving rescue efficiency and success rate.

Through technological integration and innovation, Dingjian Tiantong satellite phone has built an integrated emergency system of "communication-positioning-distress" and has become the "lifeline" in scenarios such as border patrol and emergency rescue. It not only improves border control capabilities, but also demonstrates the strategic significance of independent controllable technology in national security and people's livelihood protection.

Dingjian focuses on the R&D, production and sales of three-proof communication products such as single Beidou handheld terminals, Beidou short message terminals, RTK high-precision positioning terminals, single Beidou explosion-proof intercom terminals, explosion-proof mobile phones, anti-confidential mobile phones, 5G single Beidou law enforcement recorders, satellite communication phones, etc. It supports customized Hongmeng systems, secondary development, and provides one-stop communication equipment application solutions.
