Aralık 2019’da Çin’in Wuhan kentinde ortaya çıkan COVID 19 pandemisi birçok sektörde olduğu gibi havacılık sektöründe de büyük değişimlerine yaşanmasına neden olmuştur. Söz konusu zaman dilimine kadar “Dünyanın “sıfırdan yapılan en havalimanı” ile “yeni merkezi” şeklinde konumlandırma çalışmaları beraber strateji değiştirmiştir. Kriz nedeniyle yeniden yapılanan stratejisi, İstanbul Havalimanı i...

This paper presents an evaluation of Bluetooth positioning in a general positioning platform. Proceeding the evaluation a Bluetooth based positioning system was implemented in order to complement the theoretical evaluation with em-

Currently a platform to investigate the underwater environment is required. In this paper, we propose an autonomous underwater vehicle (AUV) with an accurate positioning system. The positioning system is developed to be accurate enough to utilize the superior navigation ability of our AUV feature. The navigation ability is acquired by the variable vector propeller mechanism. The accurate positi...

This paper discusses and investigates the effects of mobility on positioning of wireless ad hoc networks. We present a Mobility-enhanced Ad hoc Positioning (MAP) scheme, where we leverage on the mobility of nodes within the network. The scheme uses the hop counts information from fixed reference nodes to perform positioning and improves accuracy by using mobile nodes to “bridge” gaps within nei...

The paper presents an image-guided positioning robot for a single-port brain surgery robotic manipulator. Due to its limited workspace, the robotic manipulator that performs a fine operation needs to be precisely and stably positioned near the target area. For this purpose, an accurate guidance of a positioning robot to the target position using CT images is developed. The developed brain surge...

The Global Positioning System demonstrates the significance of Location Based Services but it cannot be used indoors due to the lack of line of sight between satellites and receivers. Indoor Positioning Systems are needed to provide indoor Location Based Services. Wireless LAN fingerprints are one of the best choices for Indoor Positioning Systems because of their low cost, and high accuracy, h...

The Global Positioning System (GPS) is widely used in outdoor environmental positioning. However, GPS cannot support indoor positioning because there is no signal for positioning in an indoor environment. Nowadays, there are many situations which require indoor positioning, such as searching for a book in a library, looking for luggage in an airport, emergence navigation for fire alarms, robot ...

Owing to trade imbalance, shipping companies position empty containers between ports or depots periodically. The most difficult problem for positioning is that it is not possible to know the exact amounts of empty containers required in the future. The paper deals with the problem of positioning empty containers in a port area with multiple depots. Customer demands and returning containers in d...

Many applications, such as marine navigation, land vehicles location, etc., require real time precise positioning under medium or long baseline conditions. In this contribution, we develop a model of real-time kinematic decimeter-level positioning with BeiDou Navigation Satellite System (BDS) triple-frequency signals over medium distances. The ambiguities of two extra-wide-lane (EWL) combinatio...

As functional integration has increased in hand-held consumer devices features such as Global Positioning System (GPS) receivers have been embedded in increasingly more devices in recent years. For example, the train positioning system based on GPS provides an integrated positioning solution which can be used in many rail applications without a cost intensive infrastructure. The network built i...
