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

All instruments are powered by solar cells mounted on the spacecraft body and stub wings, with estimated electrical power of over 100W.

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 MOSIS 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.
