What is cellular IoT?
What is cellular IoT? Cellular IoT refers to the use of mobile networks to connect IoT devices, enabling communication among devices using established cellular infrastructure. These devices range from smart meters and connected vehicles to remote healthcare monitoring systems and…
Designing and optimising real-time kinematics systems
Real-time kinematics (RTK) is a satellite navigation technique that offers precise positioning accuracy by using data from Global Navigation Satellite Systems (GNSS). We’ve covered satellite positioning on IoT Insider – more specifically looking at GNSS, GPS and now, RTK, to…
The accuracy of GPS: balancing power and accuracy
What is the accuracy of GPS? The global positioning system (GPS) has long been applied to use cases from smart wearables to healthcare devices and industrial applications. GPS is perhaps most widely recognised among consumers for its role in satellite-based…
