It was started as a response to the 1998 North Korean missile test over Japan. The satellite program’s main mission is to provide early warning of impending hostile launches in the region. This program is under the direct control of the cabinet. All Information Gathering Satellites have been launched by H-IIA rockets from the Tanegashima Space Center.Table of ContentsHistory[edit]List of launches[edit]References[edit]External links[edit]History[edit]On 28 March 2003, presumably partly in response to North Korea’s launch of a Taepodong-1 missile over Japan in 1998, and partly to provide a source of satellite images other than through cooperation with the US, where the US charged roughly US$10,000 for each satellite image,[citation needed] Japan launched a radar and an optical spy satellite, officially known as IGS 1A and IGS 1B.[1]\u00b7[1] These satellites follow one another at 37-minute separation in a 492\u00a0km orbit, which passes over Pyongyang at 11:22 each day, according to observations collected on the satellite watching mailing list.[citation needed]The program suffered a setback when Japan lost the second pair of satellites because of an H-IIA launch failure on 29 November 2003.[2]Except the satellite which failed in launching, a second optical surveillance satellite IGS 3A was launched on 11 September 2006.[3]A third optical satellite IGS 4A and a second radar satellite IGS 4B were launched on 24 February 2007. IGS 4A is a more advanced and experimental optical satellite.[4]A fourth optical satellite IGS 5A was launched on 28 November 2009. This satellite has a higher resolution than the previous generations.[5]Late March 2007, the first SAR satellite in the series, IGS 1B, suffered a critical power failure.[6]\u00b7[7] The satellite has since been observed to steadily come down and was clearly no longer under control.[8] An uncontrolled re-entry of this satellite occurred on 26 July 2012.[9] Since summer 2010, another of the SAR satellites, IGS 4B has also been unable to carry out its monitoring functions.[10]On 9 February 2020, Japan launched IGS-Optical 7 reconnaissance satellite from the Tanegashima Space Center aboard an H-2A rocket. The launch had been delayed by 12-days due to a nitrogen leak, located within a system that provided conditioned air to the rocket, which was discovered sometime before the countdown to launch was aborted on 27 January. Following the discovery of the leak, the rocket was returned to its vertical assembly building, where it underwent repairs. Following the completion of the repairs, the rocket was rolled back out to Launch Pad No. 1 on 7 February, before the scheduled second launch attempt.[11]List of launches[edit]Launch Date (UTC)NORAD DesignationJapanese Government DesignationSensor TypeNORAD IDInternational codeStatusGenerationBelieved ResolutionInitial Orbital ParameterVehicleResult28 March 2003IGS 1AIGS-Optical 1Optical276982003-009ARetired1st generation of opticalPanchromatic sensor:About 1 m (mono)Multi-spectral sensor:About 5 m (color)486\u2013491\u00a0km, 97.3\u00b0, 94.4 minH2A 2024SuccessIGS 1BIGS-Radar 1SAR276992003-009BRetired [6]1st generation of SARAbout 1~3 m29 November 2003N\/ANameless for launching failureOpticalN\/AN\/AN\/A1st generation of opticalPanchromatic sensor:About 1 m (mono)Multi-spectral sensor:About 5 m (color)N\/AH2A 2024FailureN\/ANameless for launching failureSARN\/AN\/AN\/A1st generation of SARAbout 1~3 m11 September 2006IGS 3AIGS-Optical 2Optical293932006-037ARetired2nd generation of optical(Improved type)1 m478\u2013479\u00a0km, 97.4\u00b0, 94.2 minH2A 202Success24 February 2007IGS 4AIGS-Optical 3VOptical305862007-005ARetired3rd generation of optical(Largely improved type)About 60\u00a0cm481\u2013494\u00a0km, 97.2\u00b0, 94.4 minH2A 2024SuccessIGS 4BIGS-Radar 2SAR305872007-005BRetired [10]2nd generation of SAR(Improved type)1 m28 November 2009IGS 5AIGS-Optical 3Optical361042009-066ARetired [12]3rd generation of optical(Largely improved type)About 60\u00a0cmUnknownH2A 202Success22 September 2011IGS 6AIGS-Optical 4Optical378132011-050ARetired4th generation of opticalAbout 60\u00a0cmUnknownH2A 202Success12 December 2011IGS 7AIGS-Radar 3SAR379542011-075AOperational3rd generation of SARAbout 1 mUnknownH2A 202Success27 January 2013IGS 8AIGS-Radar 4SAR390612013-002AOperational3rd generation of SARAbout 1 mUnknownH2A 202SuccessIGS 8BIGS-Optical 5VOptical390622013-002BRetired5th generation of optical40\u00a0cm1 February 2015IGS 9AIGS-Radar SpareSAR403812015-004AOperational3rd generation of SARAbout 1 mUnknownH2A 202Success26 March 2015IGS O-5IGS-Optical 5Optical405382015-015AOperational5th generation of optical30\u00a0cm [13] or 40\u00a0cm [14]UnknownH2A 202Success17 March 2017IGS R-5IGS-Radar 5SAR420722017-015AOperational4th generation of SAR50\u00a0cm [15]UnknownH2A 202Success27 February 2018 [16]IGS O-6IGS-Optical 6Optical432232018-021AOperationalUnknownH2A 202Success12 June 2018IGS R-6IGS-Radar 6SAR434952018-052AOperationalUnknownH2A 202Success9 February 2020 [17]IGS O-7IGS-Optical 7Optical451652020-009AOperationalHigher performance than 30\u00a0cm[18]UnknownH2A 202Success26 January 2023 [19]IGS R-7IGS-Radar 7SAR553292023-012ATestingUnknownH2A 202SuccessReferences[edit]External links[edit] "},{"@context":"http:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki24\/#breadcrumbitem","name":"Enzyklop\u00e4die"}},{"@type":"ListItem","position":2,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki24\/2020\/06\/24\/information-gathering-satellite-wikipedia\/#breadcrumbitem","name":"Information Gathering Satellite – Wikipedia"}}]}]
