Daytime Satellite Tracking

Ground-based optical observation of satellites during local daytime is now possible thanks to Numerica’s daytime satellite tracking technology.

LEO to GEO 24/7

Daytime tracking represents a major innovation for the commercial space domain awareness market, increasing the observation opportunities on LEO to GEO satellites and enabling the potential for a global network of low-cost telescopes to maintain custody of satellites through the current daylight coverage gap.

  • World’s first ever daytime optical tracking service
  • Demonstrated tracking of satellites from LEO to GEO at extreme solar elevations
  • Data-as-a-service and sensor systems available commercially
Numerica Daytime Satellite Tracking

Until now, there has not been a daytime tracking solution capable of global proliferation, let alone a commercial daytime tracking service. Closing the ground-based optical coverage gap will significantly enhance space domain awareness and space traffic management missions.

Daytime tracking technology features

  • Enabled by high-speed shortwave infrared cameras, customized optics & advanced algorithms
  • Observes Earth-orbiting satellites in broad daylight at altitudes of more than 36,000 kilometers (22,000 miles)
  • Detects space objects using shortwave infrared (SWIR) sensors during daytime hours without the use of cryogenic cooling components
  • Collects 15 GB/minute & applies image processing algorithms that fuse the data to reduce noise to near theoretical limits
  • Trial satellite observation data available from integration of the daytime tracking systems with the broader Numerica Telescope Network (NTN) comprised of more than 130+ optical sensors spanning 20+ sites worldwide
