Naval Ocean Surveillance Satellites - a 'UFO'
5th March 2004
NOSS is a group of satellites that travel as a group of three in orbit
around the Earth and sighting of this trio has given rise to many UFO
reports in the UK. On 25 October, 1999, the British Astronomical
Association offered a brief description of NOSS:
A couple of summers ago, meteor observers certainly became familiar with
the NOSS trio of satellites, which were in an equilateral pattern. Onboard
sensors apparently allowed researchers to measure precise distances
between these, and how they were affected by gravitational perturbations
over time. The NOSS satellites were also comparatively faint - visual
magnification +3 or thereabouts.
