October 26, 2018 - China Launches Communication Satellite

You're looking for a Chinese communication satellite launch on October 26, 2018, but that date doesn't match any confirmed launch in the record. No Chinese rocket lifted off that day. The nearest confirmed activity was the November 18, 2018 Long March 3B/E launch, which delivered BeiDou-3 M17/M18 navigation satellites to Medium Earth Orbit. If you're researching China's experimental communications satellite program, there's much more to uncover ahead.

Key Takeaways

• No confirmed Chinese rocket launch occurred on October 26, 2018, based on available records.
• The nearest confirmed Chinese launch was November 18, 2018, involving a Long March 3B/E rocket.
• The November 18, 2018 mission delivered BeiDou-3 M17/M18 navigation satellites to Medium Earth Orbit.
• BeiDou-3 M17/M18 were navigation payloads, not communications satellites, contradicting the query's implied payload type.
• The next significant Chinese launch after November 18, 2018 was Chang'e 4 on December 7, 2018.

What China Actually Launched on November 3, 2018?

Records show no Chinese rocket launch on November 3, 2018. If you're questioning the November launch?, the data simply doesn't support one. The nearest confirmed activity was November 18, 2018, when a Long March 3B/E carrying a YZ-1 upper stage delivered BeiDou-3 M17/M18 satellites to Medium Earth Orbit.

Regarding payload identity, those were navigation satellites, not a communications payload. Their orbital parameters? MEO, consistent with the BeiDou constellation's design requirements. Mission duration extended across the broader BeiDou-3 deployment campaign. Much like the DVD format wars of the 1990s, competing satellite navigation programs from multiple nations required significant consolidation efforts before a dominant standard could emerge.

The next significant launch after November 18 was the Chang'e 4 lunar probe on December 7, 2018. You won't find a November 3 launch because it didn't happen — the article title you're referencing contains a factual error. China's subsequent lunar ambitions culminated in the Chang'e 5 mission, which launched in November 2020 aboard a Long March 5 rocket to collect the first moon samples since 1976.

China also advanced its oceanographic research during this period, with the Haiyang 3-01 satellite designed to conduct next generation ocean color measurements in support of ecology studies and climate observation, launched aboard a Long March 2C/YZ-1S into a Sun-synchronous orbit.

TJS-10's True Mission: Military Communications or Civilian Experiment?

When China launched TJS-10 on November 3, 2023, CASC described it as an experimental communications technology satellite conducting multi-band and high-speed data transfer tests — but that official explanation hasn't satisfied satellite observers.

You're looking at a pattern of dual use ambiguity that defines the entire TJS series. SAST manufactures every satellite in the program, launches get announced only after liftoff, and airspace closures precede each mission.

TJS-10's confirmed GEO positioning over strategically sensitive regions aligns far more with SIGINT collection or missile early warning than civilian broadband experiments. COMSPOC documented active maneuvering in May 2024, yet no independent verification of signal provenance exists.

Without transparency from CASC or state media, analysts continue treating TJS-10 as a likely military asset operating behind a civilian label. The broader TJS series has drawn scrutiny since TJS-3 was observed making close approaches to satellites owned by other countries following its December 2018 launch. This kind of ambiguity mirrors how early commercial computing platforms, including systems built around the Intel 8088 microprocessor, were adapted for uses far beyond their stated civilian purposes. The satellite was carried to orbit aboard a CZ-7A rocket launching from Wenchang Space Launch Center in Hainan, China.

Long March 7A Rocket: Specs and GTO Performance

TJS-10 rode to orbit aboard the Long March 7A, a three-stage rocket with four strap-on boosters that stands 60.1 m tall and tips the scales at 570,000 kg at liftoff. Its four boosters and core first stage each run on YF-100 kerolox engines, generating 7,200 kN of total liftoff thrust.

The second stage runs four YF-115 engines producing 706 kN, while the third stage's two YF-75 hydrolox engines deliver a specific impulse of 438 s—reflecting clear propulsion advancements over earlier Long March variants.

You'll find the rocket's 4.2 m fairing handles payload integration for satellites up to 7,000 kg to GTO and 13,500 kg to LEO. That GTO capacity made it well-suited for delivering TJS-10 to its intended operational orbit. The Long March 7A is part of a new-generation rocket family developed by CALT to replace legacy hypergolic-propellant vehicles such as the Long March 2, 3, and 4 series.

The YF-100 engine at the heart of the Long March 7A's propulsion system operates on a staged combustion cycle, using LOX and kerosene propellants fed by a single-shaft turbo-pump incorporating a single-stage oxygen pump and a dual-stage kerosene pump.

Why China Launched TJS-10 From Wenchang, Not Xichang

Most TJS satellites lifted off from Xichang aboard Long March 3B/E rockets, so TJS-10's November 2023 departure from Wenchang raised immediate questions.

The launch site switch wasn't arbitrary — several mission-critical factors drove the decision:

• Payload tradeoffs: Wenchang's 19°N latitude delivers a 400–500 m/s rotational boost, maximizing Long March 7A's GTO capacity beyond what Xichang could match.
• Coastal logistics: Wenchang's seaport enabled direct rocket component delivery, streamlining operations impossible at inland Xichang.
• Weather advantages: Hainan's clear coastal skies supported reliable launch windows.

You can see China's broader strategy here — shifting heavier or specialized GTO missions southward while Xichang handles standard military communication satellite deployments. Most recently, the site supported the Tianzhou-10 cargo spacecraft launch, with the Long March-7 carrier rocket fully fueled and ready for an 8:13 a.m. Beijing Time liftoff on May 11.

The TJS program itself spans multiple suspected mission types, with satellites manufactured by Shanghai Academy of Spaceflight Technology and serving roles ranging from signals intelligence to missile early warning for the People's Liberation Army. This type of space-based intelligence gathering reflects a broader historical pattern, as coordinated satellite observation networks have proven essential to national security and strategic monitoring since the Cold War era drove early investment in orbital technologies.

TJS-10's Path From Geosynchronous Transfer Orbit to Final Geostationary Slot

Once Long March 3B/E delivered TJS-10 to a geosynchronous transfer orbit, the satellite's onboard propulsion system took over to complete the journey to its final geostationary slot. You can think of this phase as two overlapping tasks: orbital circularization and inclination reduction.

For circularization, the satellite fired its engines at apogee to raise the perigee from roughly 200-300 km up to GEO altitude, eliminating the orbit's eccentricity. Electric propulsion made this fuel-efficient, though it stretched the process across days or weeks.

Simultaneously, inclination reduction burns at apogee corrected the slight tilt inherited from Wenchang's launch azimuth, aligning TJS-10 with Earth's equatorial plane. Once it reached a circular, equatorial orbit, minor station-keeping burns positioned it precisely at its assigned geostationary longitude slot. Both inclination and eccentricity must be reduced, as correcting only eccentricity yields a geosynchronous, not geostationary orbit.

Even after reaching its final slot, TJS-10 requires periodic onboard fuel burns to counteract drift caused by lunar and solar gravity, which gradually perturb the satellite's position over time. This station-keeping challenge mirrors the approach used on commercial space stations, where propulsion thrusters are integrated into each module as independent systems to maintain precise orbital positioning without relying on external infrastructure.

TJS-10 in Context: China's Communication Technology Experimental Satellite Program

While TJS-10 represents a single launch, it's part of a broader Chinese military satellite program called Tongxin Jishu Shiyan, or TJS. Operating in geostationary orbit, TJS serves as a cover name for multiple military satellite programs manufactured by the Shanghai Academy of Spaceflight Technology.

You'll notice the program's scope extends well beyond simple ground station operations and waveform testing:

• TJS satellites conduct signals intelligence and missile early warning experiments
• TJS-3 previously approached and inspected foreign-owned satellites in orbit
• TJS-3 and TJS-10 maintained close orbital proximity, staying under 50km apart

Despite official statements describing TJS missions as "multi-band and high-speed communication technology experiments," analysts remain skeptical. China's lack of transparency keeps the program's exact military objectives classified.

What TJS-10 Reveals About China's Military Communications Strategy

Beyond its cover designation, TJS-10 reveals a calculated military communications strategy built on persistent GEO coverage, signals intelligence, and deep integration with China's broader ISR architecture.

You can trace its role through GEO signal integration with BeiDou-3 for precision targeting, Yaogan-30 for ELINT, and missile early-warning linkages tied to Huoyan-1.

Together, they form a kill web capable of supporting long-range strikes against U.S. and allied forces.

TJS-10's persistent command and control function positions the PLA to maintain real-time coordination across space, cyber, and kinetic domains. China's Guowang constellation, targeting nearly 13,000 spacecraft, further extends this sovereign, resilient communications backbone with direct dual-use C2 implications.

Its unusual GEO maneuvers mirror those of SJ-17 and TJS-3, suggesting active SIGINT operations. Analysts monitoring these developments often rely on platforms like the Financial Times, whose 700+ global journalists provide in-depth coverage of emerging geopolitical and technological competition. The same technological acceleration shaping space warfare is visible in AI-driven breakthroughs, where tools like AlphaFold have compressed decades of scientific work into months, illustrating how rapidly strategic advantages can shift across domains.

What TJS-10 ultimately reveals isn't a communication experiment—it's a combat-ready node embedded in China's expanding space-guided supremacy framework.

China's 510+ ISR Satellites and Where TJS-10 Fits in the Network

TJS-10 doesn't operate in isolation—it's one node inside a sprawling network that's grown by over 927% since 2015, now exceeding 1,189 operational spacecraft. You're looking at a space-based mesh where every satellite reinforces the others.

Here's what makes this network formidable:

• 510+ ISR-capable satellites combine optical, multispectral, radar, and radiofrequency sensors for persistent tracking of U.S. carrier strike groups
• Electro-optical integration fuses imagery with signals intelligence, enabling detection, tracking, and strike coordination
• Civil-Military Fusion pulls commercial assets directly into military ISR pipelines, expanding coverage without additional defense spending

TJS-10 slots into this architecture as a communications backbone, ensuring data collected across the constellation reaches commanders quickly. That connectivity transforms raw sensor data into actionable targeting intelligence. China's geostationary platforms, such as Yaogan-41, are capable of tracking car-sized objects across the Indo-Pacific from approximately 36,000 kilometers, making them particularly difficult to neutralize through conventional ASAT methods. China's commercial megaconstellation G60, known as Thousand Sails, is projected to scale to 13,000 satellites, further compressing the boundary between civilian and military space infrastructure. The parallel challenge facing Western defense planners mirrors the infrastructure dominance problem seen in commercial sectors, where early deployment decisions compound over time into advantages that rivals struggle to close—much as Tesla's Supercharger network now holds 52.5% U.S. market share in DC fast-charging despite accelerating competition.
