Abstract: A novel method for error correction for Very-high frequency Omni Range (VOR) Azimuth is designed and tested. The basic principle behind the working of VOR is enumerated. In the generation of phase difference at the air-borne receiver, various errors occur which impair the effective working of VOR. The aggregate value of these errors will be around 5o. Broadcom BCM2836R processor is used in the Linux environment with Mathematica10. Wolfram language is used to realize Kalman filter. Incorporating the proposed method, the aggregate error is successfully reduced to around 1o. This improvement will benefit the air operators to have more aircraft density surrounding any airport/VOR area.
