Satellites are valuable tools to increase our knowledge of climate change and its impacts, and thus properly target our action plans and response activities. Thanks to satellite data, farmers can maximize the use of their lands, which in turn benefits all Canadians. Using satellites, we can monitor changes and promote the responsible use of land and natural resources to protect our ecosystems and biodiversity.
Satellites play a critical role supporting first responders and search and rescue teams in emergency situations. Earth observation satellites and space science play an active role in improving the health of Canadians. Canadian satellites are providing information to help us monitor our waters and coastlines, protect them and guide ships.
IoT devices are being integrated into more organisations and more and more communications services are spreading beyond urbanised cities into more rural areas. Banking — Banks use navigational satellites to manage and synchronise transactions of all types and authorise card activity. Energy Networks — Energy networks use navigation satellites to organise power grids. Transport — Trains use navigational satellites for signalling and autonomous vehicles require real-time location data.
Defence — Military organisations and defence need accurate, real-time guidance for weapons systems and aircraft, as well as detailed ground intelligence for their field agents. TV — Communication satellites power scheduled TV programming as well as on-field reporting. Civil — Emergency services, such as ambulances or firefighters, use navigation systems for vehicles transport.
Consumer — Many phone applications and search engines ask to use location information to improve their service. Weather — Satellites can provide a large-scale view of weather conditions across the globe. Earth Observation satellites can also monitor environmental incidents for reasons of safety, emergency response, and policy. If the signal is lost, your service might be disrupted indefinitely. Or if the signal is spoofed or blocked, the integrity of your service is left compromised.
In particular, any detriment to the quality of communications and navigation satellite service could be devastating. So no need to worry that the sky is falling! Aren't satellites out of this world?
