Question: I'm looking for a platform that offers centimeter-level accuracy for navigation in challenging environments.

If you need a platform that can deliver centimeter-level accuracy for navigation in difficult environments, Point One is a good option. It offers a precision location stack through its RTK corrections, which means you get the same level of accuracy anywhere in the world. The solution includes Polaris RTK, a corrections network with cm-level accuracy, and Atlas INS, which combines precision GNSS with inputs from an inertial measurement unit (IMU) and other sensors for truth-level positioning in real time. It supports a broad range of GNSS devices and has features like real-time observability and advanced device management.

Another good option is Radar, an all-in-one location platform that's got a good reputation for hyper-accurate geofencing and mapping. Radar offers unlimited geofences and 5-meter accuracy, along with trip tracking and live ETAs. Its mapping abilities include geocoding APIs, search APIs and routing APIs, so it can be used for a variety of navigation needs. It also integrates with common tools and comes with enterprise-grade privacy and security.

If you need aerial navigation, Skydio has an interesting option with self-piloting drones that use AI and high-resolution cameras. The drones can fly autonomously and gather detailed information in difficult terrain, offering the best optics and remote operations. They're designed to be portable and rugged, so they're good for industries like Energy & Utilities and Defense.

Last, Mapbox is a powerful location intelligence platform that offers customizable maps, advanced navigation and precise location search. It offers interactive maps with live updating data and advanced routing engines, and it has global datasets for boundaries, traffic and movement. Mapbox is used in many different applications, including connected navigation and data analysis, and offers a tiered pricing model with a free tier.
