The first information we have about the Yunyao-1 15 to 17 comes from this post...
云遥一号15星、16星和17星出征仪式顺利举行
The launch ceremony of the 15th, 16th and 17th satellites of Yunyao-1 was successfully held
At 7:17 on May 25, 2024, the departure ceremony of Yunyao-1 15, 16 and 17 was held in Changchun Aerospace Information Industrial Park.
These three meteorological remote sensing satellites are named by Beiyang Begonia Fund, Tianjin University Science and Technology Park and Entrepreneurship Knowledge Society respectively. Dr. Zhou Pei, deputy general manager of Beiyang Begonia Fund, relevant leaders and project team members of Tianjin Yunyao Aerospace Technology Co., Ltd. and Changguang Satellite Co., Ltd. participated in this expedition.
Yunyao-1 15, 16 and 17 are new meteorological observation small satellites with the characteristics of short development cycle, high integration, light weight, small size and high cost performance. The satellite's space data products can be used for space environment detection. The satellite is mainly composed of GNSS occultation detection payload and infrared detection payload. The meteorological, space and infrared data products of the payload can be used in numerical weather, magnetic storm monitoring, earthquake prediction, marine environment prediction and other fields. The three satellites launched this time are typical applications for realizing automated testing and assembly line assembly, and are also important achievements in practicing the concept of mass production.
Yunyao-11 satellites 15, 16 and 17 will soon become members of Yunyao Aerospace's global meteorological space monitoring constellation. Yunyao Aerospace's global meteorological space monitoring constellation will form a global high-resolution, high-precision, full-scale atmospheric and ionosphere detection system, breaking the foreign technology monopoly, assisting the development of upstream and downstream industries, providing high-efficiency meteorological services for the "Belt and Road" countries, and increasing my country's international influence.
The satellite will be launched at the Shandong Haiyang Satellite Launch Center in the near future. After the successful launch, it can provide rich remote sensing data and product services for users in the meteorological, space, ocean, transportation and power industries.
The three of payloads might be as below, and they might also be named with Jilin-1....
Yunyao-1 15 (Beiyang Haitang Jijin-1) 云遥一号15 (北洋海棠基金一号)
Yunyao-1 16 (Tianjin Daxue Kejiyuan-1) 云遥一号16 (天津大学科技园一号)
Yunyao-1 17 (Chuangye Zhibenshe-1) 云遥一号16 (创业知本社一号)
As Liss pointed out, there is also an information regarding the launch of other(s) Yuyao-1 sats at the end of June from the topic
https://forum.nasaspaceflight.com/index.php?topic=61074.0So, the question is, are we talking about the same payloads here? If so, then one of those payloads also named Fujing Tiance-1 (富景天策一号).
