Abstract:

The accuracy of GPS Global Positioning System receivers depends on the geometry of the GPS satellites used in the position calculation the receiver has optimum performance when given an unobstructed view of the sky. Previous work has shown that L-band antennas mounted on 155-mm artillery projectiles have nulls or blind spots in their patterns. A Monte Carlo analysis was performed to assess the impact on system accuracy that various sized nulls would have. The analysis found that a system using the full 24-satellite constellation is very tolerant of even large antenna nulls.
