Abstract

This paper is about a navigation system for unmanned
or automized vehicles which is one of the important issues nowadays. We propose
a system that solves the issue about navigating where GPS system does not work
or cannot reach to enough accuracy. Proposed system basically consists of
setting beacons alongside the road and navigate according to bearing angles of
those beacons. The system can assist vehicles that are navigated with GPS, in
cities or between cities. The advantages of the proposed system are, providing
quick automation and being less sensitive to environmental conditions. Proposed
system can provide much cheaper maintenance and more sensitive automation than
GPS when it is assisted by a map in its data base. The MATLAB simulations of the
system prove that system is practicable and developable. In simulations it is
verified that; with this system, vehicle can keep its line with high precision.

Otomatik Araçlar İçin Radyofar Temelli Yön Bulma

Abstract

Bu makalede günümüzde yaygın bir çalışma alanı olan insansız veya otomatik araçlar için geliştirilmiş bir yön bulma sistemi sunulmuştur. Amaç, GPS(Global Positioning System) sisteminin çalışmadığı veya hatalı çalıştığı noktalarda yön bulmayı sağlamaktır. Sunulan sistem temel olarak yol boyunca arka arkaya dizilmiş radyofarlardan aldığı açı bilgisi ile yön bulma üzerine kuruludur. Otomatik araçlarda, şehir içinde veya şehirlerarası yön bulmada, GPS'e destek olma potansiyeline sahiptir. Sistemin avantajları ise; hızlı bir şekilde araç otomasyonu sağlayabilmesi ve ortam koşullarından oldukça az etkilenmesidir. Kullanıldığı mesafeye göre, GPS’den daha ucuza daha hassas otomasyon sağlayabilmektedir. Yapılan MATLAB benzetimlerinin sonuçları sistemin uygulanabilir ve geliştirilebilir olduğunu kanıtlar niteliktedir. Benzetimlerde hem düz yolda hem de virajlı yollarda; bu sistemle, yüksek hassasiyetle aracın şeridini korunduğu sonucuna ulaşılmıştır.
