BIRD (satellite)

BIRD (Bispectral and Infrared Remote Detection) is a satellite launched by ISRO in 2001 for DLR. This small (92 kg) boxlike system, with solar panel two collectors on stub wings, has remarkable fire-detection qualities. It hosts a two-channel infrared sensor system in combination with a Wide-Angle Optoelectronic Stereo Scanner (WAOSS). It also features a neuronal network classificator in orbit to reduce downlink bandwidth and cost.[2]

The unique combination of a stereo camera and two infrared cameras gives the opportunity to acquire:

  • More precise information about leaf mass and photosynthesis for the early diagnosis of vegetation condition and changes
  • Real time discrimination between smoke and water clouds

The attitude&control system of the BIRD satellite was reused in the TET-1 satellite.

gollark: Nope. It runs over TCP.
gollark: Better than what? For what?
gollark: I don't see why you would want to stuff your entire request body in headers when there's a perfectly good request body system.
gollark: Primarily that some things won't be happy with it because nobody does it. Other than that:- servers may allocate limited-sized buffers for incoming request headers so you can't put too much in them (this is somewhat problematic for cookies)- headers have character set limits while bodies can be arbitrary bytes- request bodies are generated by forms and all sane clients so stuff is mostly designed to deal with those- request bodies can probably be handled more performantly because of stuff like the length field on them
gollark: In HTTP, you mean?
