SpacePNT has developed NaviLEO, a high performance GNSS receiver platform designed to meet the most stringent needs and challenges of the New Space market


Unique Features

Highest autonomous positioning and timing precision

  • Autonomous on-board proprietary real-time precise orbit determination (POD) algorithm provides <10 cm (3D rms) in real-time onboard the satellite!
  • On-board clock provides ns-level timing synchronization

Low cost and compact design

  • Based on a COTS-based “New Space” approach
  • Implementing a radiation tolerant HW/SW/FW architecture
  • Compact design (low size, weight, and power)

Upgradable and scalable

  • Supports both passive and active antennas
  • In-flight FW/SW upgradability
  • Unique platform solution for launchers, LEO, GEO, HEO, and Moon missions!

Highly reliable architecture

  • Onboard orbital propagator for improved performance and availability
  • Supports multiple GNSS (GPS, GALILEO) over multiple frequencies
  • Supports cold redundancy (with 2 units)
  • Designed to support min. 10 years in typical LEO
