Tern AI wants to reduce reliance on GPS with low-cost navigation alternative 

The article profiles Tern AI, which raised a $4.4M seed round to develop an AI-driven Independently Derived Positioning System (IDPS) that provides precise positioning without satellite signals, aiming to mitigate risks from GPS jamming and spoofing. The model fuses vehicle and smartphone sensor data with map data, targets integration with mapping apps, claims ~4m accuracy aligned with DOT guidance, and plans commercial testing in July with a logistics partner ahead of a September launch. Target users include logistics, emergency services, and potentially DoD/DOT, positioning the solution as a low-cost, scalable alternative to satellite-based navigation.
