A system that allows users to find and track a specific position is known as positioning system. Global Positioning System (GPS) is one of top known position tracking system that commonly used to find position and location of object outdoor. Tracking an object indoor using GPS is not highly recommended because the signals transmitted through a satellite to a device indoor gets blocked and resulted in weak signals. Thus, an indoor positioning system (IPS) that tracks and positions object indoor has been implemented to overcome the issues of signals multipath that resulted from GPS. The aim of this paper is to provide up to date indoor positioning technologies and compares the technologies according to its technical perspectives.

In this paper, an indoor positioning system using Global Positioning System (GPS) signals in the 433 MHz Industrial Scientific Medical (ISM) band is proposed, and an experimental demonstration of how the proposed system operates under both line-of-sight and non-line-of-sight conditions on a building floor is presented. The proposed method is based on down-converting (DC) repeaters and an up-converting (UC) receiver. The down-conversion is deployed to avoid the restrictions on the use of Global Navigation Satellite Systems (GNSS) repeaters, to achieve higher output power, and to expose the GPS signals to lower path loss. The repeaters receive outdoor GPS signals at 1575.42 MHz (L1 band), down-convert them to the 433 MHz ISM band, then amplify and retransmit them to the indoor environment. The front end up-converter is combined with an off-the-shelf GPS receiver. When GPS signals at 433 MHz are received by the up-converting receiver, it then amplifies and up-converts these signals back to the L1 frequency. Subsequently, the off-the-shelf GPS receiver calculates the pseudo-ranges. The raw data are then sent from the receiver over a 2.4 GHz Wi-Fi link to a remote computer for data processing and indoor position estimation. Each repeater also has an attenuator to adjust its amplification level so that each repeater transmits almost equal signal levels in order to prevent jamming of the off-the-shelf GPS receiver. Experimental results demonstrate that the indoor position of a receiver can be found with sub-meter accuracy under both line-of-sight and non-line-of-sight conditions. The estimated position was found to be 54 and 98 cm away from the real position, while the 50% circular error probable (CEP) of the collected samples showed a radius of 3.3 and 4 m, respectively, for line-of-sight and non-line-of-sight cases.

Informasi untuk mengetahui lokasi benda atau seseorang merupakan salah satu hal yang penting dalam kehidupan sehari-hari. Selama ini, teknologi Global Positioning System (GPS) dapat diandalkan ketika berada di luar ruangan. Namun, ketika di dalam ruangan, GPS akan sulit menjangkau secara spesifik area bangunan. Dengan memanfaatkan teknologi Light Fidelity (Li-Fi), Indoor Positioning System (IPS) akan lebih mudah dilakukan dan mempunyai keunggulan dari segi akurasi dan efisiensi energi. Tetapi, jika dikaitkan dengan IPS, pemasangan lampu Light Emitting Diode (LED) perlu diperhatikan geometri pemasangannya. Penelitian ini membahas akurasi IPS pada Li-Fi apabila dengan berbagai bentuk geometri dan lokasi pemasangan lampu LED yang berbeda-beda. Teknik positioning Received Signal Strength (RSS) digunakan dengan mengambil kuat daya terima sebagai estimasi suatu jarak. Dengan membandingkan masing-masing bentuk geometri, maka didapatkan data konfigurasi terbaik untuk implementasi IPS. Hasil penelitian menunjukkan bahwa perbedaan jumlah lampu LED dan bentuk geometri akan berpengaruh terhadap akurasi positioning. Hasil menunjukkan bahwa geometri segi enam memiliki rata-rata error yang lebih kecil dibandingkan geometri yang lain, yakni sebesar 1,53×10?05m. Semakin banyak lampu LED atau poin referensi dengan rentang jarak lampu yang lebih rapat, maka dapat menghasilkan positioning yang lebih baik.

Indoor Positioning System (IPS) merupakan teknologi informasi untuk menentukan posisi objek di dalam ruangan berbasis wireless smartphone. Perangkat yang digunakan dalam penelitian ini adalah empat unit smartphone, satu smartphone sebagai transmitter, dan tiga smartphone lainnya sebagai receiver. Tujuan penelitian ini adalah mendapatkan model dan tingkat akurasi dari IPS berbasis wireless smartphone menggunakan teknik Global Positioning System (GPS) dengan metode absolut. Penelitian ini dilakukan dengan membuat dua model IPS dan melakukan pengukuran intensitas sinyal Wi-Fi berdasarkan masing-masing model IPS yang telah dibuat untuk mendapatkan persamaan linier antara jarak dan intensitas sinyal Wi-Fi. Persamaan linier yang didapatkan dari model IPS digunakan untuk menentukan jarak antara receiver dan transmitter berdasarkan intensitas sinyal Wi-Fi yang terukur pada saat pengujian model, kemudian informasi jarak tersebut digunakan untuk menentukan posisi objek (transmitter). Hasil penelitian menunjukkan bahwa Model 1 IPS berbasis wireless smartphone mampu mengestimasi posisi dengan rata-rata tingkat kesalahan mencapai 4,46 m dan tingkat akurasinya mencapai 76,51%. Model 2 IPS mampu mengestimasi posisi dengan rata-rata tingkat kesalahan 9,68 m dengan tingkat akurasinya mencapai 49,03%. Berdsarakan hasil tersebut, dapat disimpulkan bahwa model 1 IPS memiliki tingkat akurasi yang lebih baik untuk mengestimasi posisi objek daripada model 2 IPS.

Air transport is the fastest way to reach areas with no direct land routes for ambulances. This paper presents the development of a quadcopter-based rapid response unit in an efficient aerial aid system to eliminate the delay time for first aid supplies. The system comprises a health monitoring and calling system for a field person working in open areas and a base station with the quadcopter. In an uncertain situation, the quadcopter is deployed from the base station towards the field person for immediate help through the specified path using constant Global System for Mobile (GSM)- and Global Positioning System (GPS)-based connections. The entire operation can be monitored at the base station with a Virtual Reality (VR) head-tracking system supported by a smartphone. The camera installed on the quadcopter is synchronized with the operator’s head movement while wearing a VR head-tracking system at the base station. Moreover, an Infrared (IR)-based obstacle-evasion model is implemented separately to explain the working of the autonomous collision-avoidance system. The system was tested, which confirmed the reduction in the response time to supply aid to the desired locations.

Recently, indoor localization has witnessed an increase in interest, due to the potential wide range of using in different applications, such as Internet of Things (IoT). It is also providing a solution for the absence of Global Positioning System (GPS) signals inside buildings. Different techniques have been used for performing the indoor localization, such as sensors and wireless technologies. In this paper, an indoor localization and object tracking system is proposed based on WiFi transmission technique. It is done by distributing different WiFi sources around the building to read the data of the tracked objects. This is to measure the distance between the WiFi receiver and the object to allocate and track it efficiently. The test results show that the proposed system is working in an efficient way with low cost.

The number of injuries is increasing on a regular basis, as are concerns about driver and passenger safety. Countries that have minimized road traffic risk effectively have adopted a "systems approach" to road safety. The issue of road safety is centered on speed. There is a clear connection between speed and the number of accidents as well as the seriousness of the crash's consequences. This framework proposes a speed limit camera monitoring/tracking system that uses the Global Positioning System (GPS) and cloud computing with the Software-as-a-Service (SaaS) module to provide valuable information about roads in order to improve safety. It also alerts the driver about signs, breaks, and which roads it connects to in the future.
