If they have control of the satellite, including pointing and commanding, and can downlink image data, that's not terrible for a first try. They can buy any images they need. They can't get this kind of experience without a learning curve.PS $5.6B Taiwan ~ $190M US

More detailsFormoSat-5 images out of focus; adjustment may take months: NARLabsQuoteTaipei, Sept. 19 (CNA) The first photos taken by Taiwan's FormoSat-5 satellite were fuzzy and marred by light spots, which were caused by a focusing problem on the satellite's remote sensing instrument (RSI), the designer National Applied Research Laboratories (NARLabs) said TuesdayThe NT$5.6 billion (US$186 million) FormoSat-5, which was launched in the United States Aug. 25 aboard a SpaceX Falcon 9 rocket, is designed to capture panchromatic images with a resolution of up to two meters per pixel, and multispectral images with a resolution of four meters per pixel.However, the first images of Earth taken by the RSI were blurry and those of urban areas were marred by light spots, Yu Shiann-jeng (余憲政), deputy chief of NARLabs' National Space Organization (NSPO), confirmed in the wake of local media reports on the issue.Yu said that after days of observation, the NSPO had concluded that there was a problem with the RSI's focusing function and was trying to make some adjustments.Regarding the light spots on the images, he said the NSPO was trying to adjust the position and interior temperature of the satellite, among other measures being taken to solve the problem.The NSPO will also compare the images taken by FormoSat-5 and its predecessor FormoSat-2, using software to improve the former's image resolution, Yu said.Meanwhile, NARLabs Vice President Wu Kuang-chong (吳光鐘) said the initial testing of FormoSat-5 will take time."The current assessment is that the image adjustment will take about two to three months to complete," he said.FormoSat-5, a 450-kg octagonal shape mini-satellite that is 2.8 meters in height and 1.6 meters in diameter, was designed and built by the NSPO.The satellite's mission is to advance and demonstrate Taiwan's indigenous space technology in the field of remote sensing satellites, to continue to serve global imagery users previously served by FormoSat-2, and to promote domestic space science research, according to the NSPO.FormoSat-5 carries an optical remote sensing payload and a science payload to execute remote sensing missions and perform science research, respectively.

Taipei, Jan. 24 (CNA) Taiwan's FormoSat-5 satellite detected changes in the ionospheric days before a major earthquake in the Middle East last November, which bodes well for the prediction of quakes in the future, a Taiwanese scientist said Wednesday.The data collected by FormoSat-5 on the changes in the ionosphere before the earthquake last November indicates that the satellite is world-class in terms of precision and speed, said Liu, a space physics scientist.
Dubious. Besides the fact that I'm not really sure on how an imminent earthquake would be affecting the ionosphere, foreknowledge of a quake isn't enough. You'd also have to know where it was going to occur. Just knowing there's going to be an earthquake tomorrow doesn't help much if I can't tell the difference between an earthquake in Los Angeles and one in Lahore, Pakistan.
On 24 August 2017, a SpaceX Falcon 9 rocket departed from Vandenberg Air Force Base in California, carrying Taiwan's FORMOSAT‐5 Earth observation satellite into orbit. The lightly weighted solo payload enables the rocket to fly a lofted trajectory for direct insertion at the mission altitude of 720 km. This unique nearly vertical trajectory is different from the usual satellite launches that the rockets fly over horizontal trajectory and insert satellites at 200 km altitude followed by orbit maneuvers to its mission altitudes. Consequently, the rocket launch generated a gigantic circular shock wave in the ionosphere covering a wide area four times greater than California. It is followed by ionospheric hole (plasma depletions) due to rapid chemical reactions of rocket exhaust plumes and ionospheric plasma. The ionospheric hole causing large spatial gradients could lead to ~1 m range errors into GPS navigation and positioning system. Understanding how the rocket launches affect our upper atmosphere and space environment is important as these anthropogenic space weather events are expected to increase at an enormous rate in the near future.
