Space is full of exciting applications! But no other application has become as indispensable as GPS –  or other systems like BeiDou in China or Galileo in Europe. We can call them all “GNSS” for Global Navigation Satellite Systems.

Imagine for a minute if GPS stopped working: How would people call an Uber and who’s using paper maps these days? Financial transactions using its accurate timestamping would also come to a halt. In the UK alone losing GNSS just for 5 days would impact the economy by £5.2bn.

There is simply an insatiable demand for tracking objects. IoT analytics estimate that by 2025 there will be over 600 million tracking units using LPWAN (low power wide area network) technologies, with an expected global asset tracking market worth $36.3B.

As much as GPS is an amazing system, it has a few limitations when used in isolation.  Especially with battery powered devices, it can consume significant power, it can’t work indoors and its location reporting is only as good as the availability of a communication network needed to transmit the location info. Read on to see what we can do about these!
