Move over, GPS: Navigation satellites in low-Earth orbit are making a comeback
Xona aims to deploy 258 satellites into low-Earth orbit as a GPS alternative.
TL;DR
- LEO navigation satellites can provide 100 times stronger signals than GPS, improving accuracy in cities, under foliage, and indoors.
- These new systems are designed to be more resilient to GPS jamming and interference.
- Xona Space Systems plans to launch its first six production Pulsar satellites in October 2026, with early service in 2027.
- The full Pulsar constellation will consist of 258 satellites, aiming for centimeter-level location accuracy globally.
- Pulsar satellites will also offer precision timing signals, with an accuracy goal of within 10 nanoseconds, using a software-based approach.
- The development of LEO navigation systems is facilitated by lower launch costs and advancements in satellite technology.
- Xona is focusing on in-house satellite bus manufacturing and ensuring compatibility with various rocket launch providers.
- Other companies like TrustPoint are also developing LEO navigation services.
