💻90s GPS Project Built on 25MHz CPU Beats First-Gen Devices
A 90s GPS project that could've been a billion-dollar business
TL;DR
A 90s GPS project using Hipparchus library on a 25MHz CPU outperformed early consumer GPS devices. It could've been a billion-dollar business but was derailed by financial issues and IP complications.
In the 90s, a GPS project was built on a 25MHz 486-SX CPU with 32MB of RAM, running Hipparchus library for GIS applications. This project, twice as fast as early consumer GPS devices, could've been a billion-dollar business but was derailed by financial issues and IP complications. The project's unique approach to math calculations, using Voronoi Cells and reducing most math to 8- and 16-bit integers, allowed it to work well on limited hardware. The first consumer GPS devices had tiny monochrome screens, while this project updated a 1024x768 color display every 2 seconds.
Key Points
Project built on 25MHz 486-SX CPU with 32MB RAM, 1990s
Hipparchus library used for GIS applications, 1990s
Project twice as fast as early consumer GPS devices, 1990s
Updated 1024x768 color display every 2 seconds, 1990s
First consumer GPS devices had tiny 360x240 monochrome screens, 1990s
Why It Matters
If you're working on hardware-constrained GIS applications, the Hipparchus library's approach to reducing math to 8- and 16-bit integers could be a game-changer. It allowed the project to run efficiently on a 25MHz CPU, outperforming early consumer GPS devices. However, the project's financial issues and IP complications highlight the importance of clear ownership and funding in tech ventures.
