The satellite internet industry is transitioning from the stage of "manufacturing satellites" to the stage of "utilizing satellites": the deployment of constellation networking is accelerating, while ground monitoring has become a prominent weak link in the industry, and Sixin Feiyang has seized the opportunity to take a key position in this sector.
The construction of LEO constellations has entered a normalized stage, and the satellite internet is shifting from "satellite manufacturing" to "satellite application", driving a synchronous surge in demand for ground-side monitoring, operation and maintenance, and security management. Beijing Sincere Fly Information Technology Co., Ltd. (hereinafter referred to as Sincere Fly) takes high-performance parallel computing and software-defined radio as its core technical foundation, provides satellite operators with an integrated monitoring solution covering the full life cycle of signals, and is pushing forward a new round of financing at the same time.
Accelerated Constellation Construction Makes Satellite Monitoring a Short Board in the Industry
The 2026 *Government Work Report* explicitly put forward "accelerating the development of satellite internet" as a separate task for the first time, and the outline of the 15th Five-Year Plan has also made synchronous arrangements to accelerate the construction of LEO satellite internet. Public information shows that there are 238 satellites of the Qianfan constellation operating stably in orbit, and about 180 satellites of the GW constellation in operation. The two major LEO constellations are planned to deploy 15,000 and 13,000 satellites in the long term respectively. While the scale of constellations is expanding rapidly, the capital market continues to heat up: Yuanxin Satellite completed a Series B financing of about 70 billion yuan in August 2026, with an estimated valuation of about 500 billion yuan; the financing amount in the commercial aerospace sector in the first quarter of 2026 exceeded 80 billion yuan, a year-on-year increase of about 460%.
Compared with the booming satellite manufacturing and launch segments, the ground-side monitoring and operation support capacity remains a relatively weak link. The growing number of constellations has made the spectrum environment increasingly complex, and signal quality assessment, interference troubleshooting, unauthorized access identification and compliance monitoring all rely on the support of professional equipment and systems. The coexistence of high-throughput satellites and multiple communication systems makes it difficult for traditional single-standard monitoring methods to cover the whole domain. How to realize full-domain signal situational awareness at a controllable cost has become a key proposition for the industry to move from constellation construction to operation, and Sincere Fly chooses to cut into this segment.
The Software-defined Radio Platform Opens Up the Full Chain from Signal Perception to Service Analysis
Headquartered in Dongsheng International Science Park in Beijing, Sincere Fly has R&D and technical support centers in Chengdu and Xi'an, satellite integration and verification bases in Zhaoqing and Sanya, and an office in Shanghai. It currently has more than 200 employees, 78% of whom are scientific researchers. The company's technical accumulation focuses on three directions: high-performance deep protocol processing, high-performance parallel computing and software-defined radio, on the basis of which it has formed three self-developed underlying platforms: the software-defined radio platform, the high-performance in-depth protocol restoration and analysis platform, and the Modular Open System Architecture (MOSA) for network data processing.
Based on the above platforms, Sincere Fly has launched the V-series integrated satellite communication monitoring solution, covering functions such as satellite signal survey, satellite service monitoring, satellite terminal positioning and satellite signal simulation. It can help operators evaluate key indicators such as signal strength, transmission quality, delay and bit error rate, identify security threats such as unauthorized access and signal interference, and support regulatory compliance requirements such as spectrum allocation and power restriction.
The core technical capabilities are continued and verified in its subsidiary Beijing Tianyuan Special Communication Technology Co., Ltd. (founded in 2009). Focusing on the R&D of high-throughput satellite internet monitoring systems covering mainstream international standards, Tianyuan Special Communication has broken through foreign technological blockades. It is one of the few domestic enterprises that have the integrated processing capacity covering satellite signal spectrum perception, demodulation and receiving processing, protocol analysis and restoration, data analysis and mining, and situational visualization. Its related products have been put into use in the national defense, security, government and scientific research sectors. The company has industry access qualifications such as military industry qualifications and quality systems, has a national-level postdoctoral research workstation, holds more than 40 software copyrights and has applied for nearly 20 patents.
Verified by Multi-industry Customers, Commercialization Pace Accelerates
Public bidding information shows that Tianyuan Special Communication ranked first in the evaluation of the satellite communication demodulator equipment procurement project, and has successively won bids for multiple projects including satellite communication equipment procurement and network data analysis and processing equipment procurement, with a total of more than 100 bidding participations. Most of the customers of such projects are institutions with long verification cycles and high access thresholds, and the consecutive winning of bids indirectly confirms the stability of the company's products and engineering delivery capacity.
In terms of commercialization paths, Sincere Fly takes satellite operators, constellation operators and industry private network users as its core target customers, and also serves national defense, security, government and scientific research institutions. The company's partners include enterprises such as China Mobile, China Unicom, China Telecom, ZTE, Sugon, as well as research institutions such as Tsinghua University, Beijing University of Posts and Telecommunications, Chinese Academy of Sciences, and Harbin Institute of Technology. Industry-university-research collaboration provides support for its participation in standard formulation and talent reserve.
The company has successively obtained the certifications of National High-tech Enterprise, Specialized, Refined, Differential and Innovative Small and Medium-sized Enterprise, and Gazelle Enterprise, and passed the National High-tech Enterprise Certification in 2023 (Registration No. GR202311002054). As the construction of LEO constellations enters the peak period and the access of satellite internet services is opened in an orderly manner, the demand for monitoring, operation and maintenance for operators is expected to continue to grow. Sincere Fly is pushing forward a new round of financing to support R&D investment and commercial expansion in the next stage.
