NTN trackers: use cases, challenges, and solutions 

Non-terrestrial networks (NTNs) extend mobile and IoT connectivity beyond terrestrial infrastructure via satellites, low-altitude platforms (LAPs), and high-altitude platforms (HAPs). NTNs bridge connectivity gaps in areas without conventional cellular coverage, fiber, or copper fixed-line infrastructure - helping to connect IoT devices such as NTN trackers in remote locations or those where terrestrial networks are compromised. NTN technology is therefore unlocking new value across a wide range of use cases including maritime and offshore operations, logistics, agriculture, energy and emergency response.

How NTN ensures global tracking coverage with reduced complexity and cost

NTN support is classified in 3GPP standards under two main modes: NR‑NTN (5G New Radio via satellite) and IoT‑NTN (extensions of NB‑IoT and LTE‑M). These enable direct-to-device communication, whereby IoT devices can connect straight to satellite infrastructure using standard cellular protocols. This takes place either via licensed Mobile Satellite Service (MSS) bands or terrestrial mobile spectrum under specific coordination. The standardization of these capabilities under IoT-NTN and NR-NTN is transforming the landscape for IoT tracking through true scalability. NTN trackers offer global reach, simple hybrid device deployment, and resilience beyond terrestrial limits, and can now be manufactured confidently at scale.  

NTN trackers also extend asset visibility without requiring designers to design in separate support for both terrestrial and satellite connectivity. This allows for reduced cost and complexity. Applications such as shipping or livestock tracking can now adopt NTN IoT devices, where costs would previously have been prohibitive. Other use examples include fleet vehicle trackers, environmental sensor trackers, and personal safety NTN tracker beacons. 

Solutions to technical and regulatory challenges in NTN tracker development

There remain considerable challenges to navigate in NTN tracker development, however. Spectrum and regulatory complexity for instance can pose a major hurdle. NTN device designers must also account for distinct technical characteristics. These including propagation delay, link budget constraints from long transmission paths, multi-RAT and frequency support for hybrid connectivity. NTN systems must handle high latency, Doppler shifts (especially with fast-moving LEO satellites), signal attenuation, seamless handovers, and power management constraints. Strong mobile and satellite network operator partnerships are also critical to success.  

By successfully navigating these challenges, designers can achieve continuous, world-wide coverage in logistics, critical infrastructure monitoring, environmental sensing, and beyond. Join this Masterclass, with leading IoT ODM Ikotek, to learn about design challenges, solutions and best practices in NTN tracking. The session includes plenty of time for Q&A with experts.
