description: Urban Sky is a Denver-based aerospace company, founded in 2016, that designs and operates reusable stratospheric
  microballoons for high-altitude remote sensing, persistent aerial surveillance, communications relay, and atmospheric data
  collection. Its balloons launch in under five minutes, float at 61,000-75,000 feet for multi-day missions, and carry the
  modular Wallabee payload platform with RGB, VNIR, and LWIR thermal sensors delivering 10cm-resolution imagery with real-time
  downlink. Through its Atmosys software platform, Urban Sky publishes an SDK for developers (JavaScript and Python, delivered
  via CDN loader) that streams real-time balloon telemetry over WebSocket and provides mission imagery access, serving defense
  and intelligence, commercial monitoring, and science and weather markets. Urban Sky is a Techstars portfolio company.
