China Launches 7th Group of 18 Qianfan Satellites

7 Apr 2026: China launched a Long March-8 with the seventh group of 18 SpaceSail satellites from Wenchang. According to official sources, the SpaceSail (Qianfan) Constellation, is developed by Shanghai SpaceSail Technologies Co., Ltd. to “provide global users with low-latency, high-speed and ultra-reliable satellite broadband internet services.” With this launch there are now 126 satellites in orbit.

According to official sources, the SpaceSail (Qianfan) Constellation, is developed by Shanghai SpaceSail Technologies Co., Ltd. to “provide global users with low-latency, high-speed and ultra-reliable satellite broadband internet services.” With this launch there are now 126 satellites in orbit. This is the first Qianfan launch in 193 days (there were 220 days between Groups 5 & 6). SpaceSail had started with a much higher launch cadence, launching Groups 1-5 on an average 54 days apart. A significant number of Qianfan satellites appear to have experienced issues in reaching their operational orbits. Launch Video.

– SpaceSail launched its 7th group Qianfan satellites into the orbital plane between groups 5 & 3 (see graphic). All planes are inclined 89° with a 20° of RAAN offset between each plane. With this launch, 7 of the 9 planes are in use. SpaceSail may want to augment batch 2 due to 15 of 18 satellites failing to reach their operational SMA of 1,069km.

Constellation Summary:

Of 126 Qianfan satellites on orbit, 87 have reached their operational altitudes of 1,069kms.

  • Group 1 (60379-60396) (launched 6 Aug 2024) : 17 of 18 satellites reached operational SMA. Qianfan 7 (60385) has not maneuvered and may be inoperable.
  • Group 2 (61552-61569) (launched 15 Oct 2024): Only 3 of 18 satellites (Qianfan 29, 30 & 32) reached their operational SMA.
  • Group 3 (62238-62255) (launched 5 Dec 2024): 16 of 18 satellites reached their operational SMA. Qianfan 39 & 42 appear to be struggling.
  • Group 4 (62785-62802)(launched 23 Jan 2025) : 18 of 18 satellites reached their operational SMA.
  • Group 5 (63159-63176) (launched 11 Mar 2025): 16 of 18 satellites reached their operational SMA. Qianfan 77 & 83 appear to be struggling.
  • Group 6 (66033-66050) (launched 17 Oct 2025): 17 of 18 satellites reached their operational SMA. Qianfan 101 (66043) remains at 800km.
  • Group 7: (launched 7 Apr 2026): satellites have not been added to the catalog yet.
