Suppression of Pulsed Interference through Blanking

Abstract:	In November 1999, the Interagency GPS Executive Board (IGEB) endorsed a set of recommendations on implementing the third civil GPS frequency (L5) that included certain measures to be taken within the United States to ensure that L5 can coexist with government systems operating at the same or nearby frequencies. These recommendations were based on analyses conducted in 1999 that assumed that pulse blanking is employed by GPS L5 user equipment. This paper describes the impact of pulsed interference on GPS user equipment and presents the results of simulation and hardware tests that were conducted this year to validate the assumed performance of L5 user equipment with blanking.
