Sasken developed hand-held satellite phones for a global customer. 

The customer needed a robust and reliable mobile device to work in their satellite network all around the world. The device should also have a longer life span in comparison to the standard consumer electronics on the market.

Sasken ended up designing two generations of hand-held satellite phones. The first generation provided good robustness, reliable connections, and long battery life. The challenge was to do the design with longer lifespan components to increase the product lifespan. 

The second generation was done with improved mechanics and features. At the same time the goal was to improve some of the Gen1 product components' availability. For both generations Sasken did the design rounds, prototype testing and type approvals 

The first-generation product was sold for several years with minor component updates. It also turned out to work in most remote places across the world and reliability good. Some components remained at their End-of-Life stage, necessitating the use of a second-generation device to address these shortages. 

The second-generation device not only prolonged the selling period of the product, functioning as effectively and reliably as the first generation, but also introduced significant updates, enhancing performance significantly.
