Results of R. F. I. Measurements Made in the G. P. S. Band on a General Aviation Aircraft.

Abstract

The U.S. Department of Transportation/Transportation Systems Center performed tests aboard a General Aviation aircraft in an effort to characterize the radio frequency interference (R.F.I.) environment, encountered by the receiving system of this type aircraft, in the Navstar Global Positioning System (G.P.S.) L sub 1 frequency band, 1575 MHz + or - 10 MHz. Results of the R.F.I. measurements, performed in the Boston, Mass. area in December 1978, are presented along with an analysis of the interference potential of the third harmonic of television station Channel 23 to the performance of a G.P.S. receiver designed to operate on the L sub 1 C/A signal. The results show that no significant R.F.I. was observed in the L sub 1 band of the G.P.S. which leads to the conclusion that R.F.I. should not pose a serious limitation to low cost G.P.S. receiver design for General Aviation.
