Gather satellite communication and indoor positioning signal coverage cases; help partners solve core challenges such as signal dead zones and inaccurate positioning!
Given that the traditional timing system in the computer room has several shortcomings such as high antenna installation costs, scarce rooftop resources, vulnerability to interruption without backup, signal degradation over long distances, and lack of operation and maintenance monitoring, the GPS/Beidou clock synchronization intelligent allocation solution has been formed.
A provincial power company has multiple substations under its jurisdiction. The number of protection devices, measurement and control devices, and monitoring systems in these substations is large and widely distributed. The original timing method was scattered, lacked redundancy, and was vulnerable to interference, resulting in the time of each system being out of sync, which affected the safe and stable operation.

Provide high-precision satellite signal coverage in indoor, garage and other enclosed and shielded environments, addressing issues such as satellite signal attenuation, insufficient antenna performance, poor signal compatibility and data synchronization, which lead to unstable positioning accuracy and frequent loss of lock, and make it difficult for various mobile operations to be carried out continuously.
A smart driving test base needs to conduct autonomous driving algorithm tests in indoor laboratories and semi-enclosed garages. The original signal solution is unable to provide stable RTK fixed solutions, resulting in significant positioning drift and exceeding the time delay limit, which cannot meet the testing standards.

By designing with a high-gain outdoor receiving antenna for Tian Tong, a forwarding host, and an indoor omnidirectional transmitting antenna, stable coverage of the Tian Tong-1 satellite signal can be achieved within the ship's cabin, indoors, and in enclosed environments.
During the voyage of several operational vessels of a certain ocean shipping company, the satellite communication signal of the ship's cabin was completely blocked by the metal hull. The crew members were unable to use the Tian Tong terminal inside the cabin, making it difficult to ensure emergency communication and daily communication.

By adopting a comprehensive solution including WiFi RSSI fingerprint positioning, multi-AP collaborative listening, non-intrusive data collection and location calculation, as well as indoor vector map rendering, we aim to address the issues of indoor positioning deficiency in shopping malls, which leads to poor customer movement experience, lack of data support for operations, insufficient marketing precision, and low efficiency in car park management.
The commercial complex in the core business district of a certain city has a total construction area of 120,000 square meters, including 6 floors of commercial space and 2 floors of underground parking. There is no GPS signal inside the venue, making it difficult for customers to find their stores or locate their vehicles. The passenger flow data cannot be statistically analyzed, and operational decisions rely on experience. The marketing push accuracy is low. Therefore, a feasible, low-cost, and imperceptible WiFi indoor positioning solution is urgently needed.

In light of the problems such as severe signal attenuation of the steel structure roof of the bus station, the closed garage, and the semi-closed parking and maintenance area, as well as the issue of poor satellite signal penetration, advanced technologies such as high-sensitivity satellite signal acquisition, low-noise signal amplification, indoor uniform coverage, and dual-mode multi-frequency compatibility have been adopted to ensure stable GPS/Beidou signal coverage in these areas.
The bus group of a certain city has multiple large bus depots. Due to factors such as building obstructions and metal structure attenuation, the satellite signals inside the stations are severely insufficient. The vehicle positioning system frequently fails, the intelligent dispatching system cannot be used normally, and the vehicle scheduling, entry and exit management, and safety monitoring are all affected. Therefore, a stable and reliable indoor satellite signal coverage solution is urgently needed.

Using Bluetooth 5.1 AOA (Angle of Arrival) positioning technology, it achieves sub-meter-level precise positioning through a multi-antenna array. Combined with anti-multipath interference algorithms and high-concurrency access algorithms, it is suitable for warehouse wide channels, high shelves, and densely populated operations involving personnel and equipment. It supports seamless integration with WMS, MES, ERP, and TMS, meeting the requirements of warehouse digital management.
The client is a large-scale regional e-commerce distribution center with over 3,000 SKUs. The daily inbound and outbound order volume is huge. The manual search for goods is inefficient, the inventory cycle is long, and the error rate is high. Therefore, they urgently need a low-cost, easily implementable, and quickly deployable indoor positioning system to enhance the operational efficiency and management level of the warehouse.

This device integrates the RNSS satellite system and the RDSS satellite system, and can provide stable and reliable GNSS satellite signal coverage and Beidou short message transmission and reception for remote areas without public networks, satellite signal blocked areas, indoor command posts, temporary shelters, and disaster relief tents, etc., which are enclosed places.
A provincial emergency management department is responsible for rescue operations in mountainous areas, forested regions and areas prone to disasters. After a disaster occurs, the public network is prone to being disrupted. Moreover, there is no satellite signal inside temporary command tents and emergency mobile shelters, and emergency terminals cannot be located for network connection or send/receive short messages.

The Tiantong-1 satellite signal repeater is a two-way relay device designed to resolve indoor satellite signal shielding, enabling satellite signals to penetrate buildings for indoor coverage.
Currently, WiFi, Bluetooth and UWB are the three most widely adopted technologies for high-precision indoor positioning. Based on distinct signal transmission principles, they differ significantly in positioning accuracy, cost, power consumption and applicable scenarios, each with unique strengths and limitations in practical deployment.
