UNIFORM-1

UNIFORM-1 or University International Formation Mission is a Japanese micro-satellite launched in 2014.[2] The satellite is built around a wildfire detection camera and features the following instruments:[3][4]

  • Microbolometer infrared camera with resolution 200m and swath width 100 km.
  • visible-light camera to assist in wildfire detection

Launch

UNIFORM-1 was launched from Tanegashima, Japan, on 24 May 2014 at 03:05:00 UTC by an H-IIA 202.[5]

Mission

The satellite is intended for wildfire detection, especially in the south-east Asia region.[6] The satellite has a less accurate infrared sensor compared to other infrared satellites, but an envisioned constellation of UNIFORM satellites would allow for a short revisit time at the fraction of the cost of the Landsat 7 or MODIS satellites. Mission data is down-linked in S-band and X-band, while control up-link is S-band only.[4]

The Wakayama University and JAXA has refused to publish data and/or information which are not officially published.
