چکیده

در سال‌های اخیر تقاضا برای سرویس‌های مکان‌یابی با پوشش مناسب و دقت بالا به سرعت افزایش یافته است. سیستم‌های مکان‌یابی ماهواره‌ای تقاضای بسیاری از کاربران را رفع می‌کنند و سرویس‌های مکان‌یابی با پوشش جهانی و دقت مناسب ارائه می‌دهند. با این وجود این سیستم‌های مکان‌یابی ماهواره‌ای توسط کشورهای توسعه‌یافته ساخته و کنترل می‌شوند و سرویس‌های مکان‌یابی دقیق آن به ندرت در اختیار کاربران غیرنظامی و سایر کشورها قرار می‌گیرد. همچنین سیگنال سیستم‌های ماهوارهای نویزپذیر و کم قدرت بوده و مناسب مکان‌های بسته نیست. استفاده از سیستم موقعیت‌یابی محلی در کنار موقعیت‌یابی جهانی از جمله برنامه‌هایی است که دولت‌ها در آینده نزدیک به منظور افزایش قابلیت اطمینان موقعیت‌یابی، افزایش پوشش کاربران و کاهش خطای سیستم به دنبال آن هستند. در این پژوهش پس از معرفی سیستم‌های موقعیت‌یابی محلی، به مهم‌ترین کاربردهای آن و مقایسه شاخص‌های آن با استانداردهای موقعیت‌یابی بین المللی پرداخته می‌شود و بازار آن در ایران مورد تجزیه و تحلیل قرار می‌گیرد.

چکیده [English]

Demand for positioning services with proper coverage and high accuracy has been increased rapidly in recent years. A global positioning system solves many users’ requirements and presents positioning services with global coverage and proper accuracy. However, satellite-based positioning systems are made and control by Developed countries and their precise location services are rarely available to civilians and other countries. Also, the signals of the satellite systems are fallible and low-power, and are not suitable for closed locations. The use of a local positioning system along with global positioning is one of the programs that governments are urging in the future to enhance the reliability of the positioning, increase coverage of users and reduce the system error. In this research, after introducing local positioning system and its most important applications, its indicators will be compared with international positioning standards and its market in Iran will be analyzed.
