air traffic data


Satellite-based coverage

Ground based air traffic surveillance is designed to work around airports and populated areas but it falls short, or simply doesn’t exist over oceanic areas or the poles. Satellite-based coverage is free from those limitations and is the only way to reliably track aircraft over oceans and remote regions.

Uniquely Qualified

In 2016, Spire launched Sense, a ship tracking product, which relays the position of every Automatic Identification System (AIS) equipped ship in the ocean. ADS-B, which is used to track aircraft, is a very similar technology. The first Spire satellites equipped with ADS-B tracking are currently being built.

AirSafe Fully Operational in 2018

Spire’s complete AirSafe service will go live in 2018 in time for our customers to meet the ICAO 15-minute mandate.

Vastly Improved Emergency Response

Mandatory tracking standards are designed to make the skies safer and decrease the amount of time it takes to respond to emergencies. In many aircraft disasters, the lack of reliable tracking technology has left first responders to search insurmountably large regions.
