This paper presents a new type of Global Positioning System/Inertial Navigation System (GPS/INS) providing higher navigation accuracy under large initial heading error. The mechanization introduced is applicable to low cost GPS/INS systems and enhances the performance when the heading error is large. The proposed approach has the capability to decrease large heading errors very quickly and can start the strapdown navigation computations under poor heading accuracy without any special alignment procedure. Although the design is applicable to land, sea and aerial vehicles, a land vehicle is used for the performance tests. The test is conducted around a closed path and the proposed system is compared to a GPS/INS system based on small attitude error assumption. The performance of both systems is given in this paper.


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.

This work is a SMS (Short Message Service) based tracking system, that uses a Global Positioning System (GPS) and GSM module which is installed in a secret part of the vehicle and is in charge of tracking the vehicle and sending the location of the vehicle in terms of coordinates to the GSM (Global System for Mobile communication) module. The GSM module receives the coordinates via SMS in which the information is sent to the owner of the vehicle or the police and the vehicle’s position can be located in a map with the aid of the Google Maps application. This work implements the foundation of GPS, GSM, and all other embedded systems, with the use of their concepts to produce a vehicle tracking device that is cheaper and more effective than other tracking device in the market today.

In this paper, an onboard vision-based system for the autonomous landing of a low-cost quadrotor is presented. A novel landing pad with different optical markers sizes is carefully designed to be robustly recognized at different distances. To provide reliable pose information in a GPS (Global Positioning System)-denied environment, a vision algorithm for real-time landing pad recognition and pose estimation is implemented. The dynamic model of the quadrotor is established and a system scheme for autonomous landing control is presented. A series of autonomous flights have been successfully performed, and a video of the experiment is available online. The efficiency and accuracy of the presented vision-based system is demonstrated by using its position and attitude estimates as control inputs for the autonomous landing of a self-customized quadrotor.

Major significant challenge looked by the current reality is the developing measure of wastage (garbage) produced each day. Because of urbanization, population explosion and ill-advised methods for waste gathering, waste is being created on an enormous size. Hazardous infections, decrease in the nature of style in the earth, air and water contamination are for the most part resultant issues of unattended wastage primarily because of carelessness in wastage assortment. Hence, there are various accessible advances which go for successful accumulation of waste. In this paper, IoT have been utilized to handle smart wastage bins which are used to gather wastage and avoid it from spilling over. Global Positioning System (GPS), Arduino UNO microcontroller, ultrasonic sensor, ESP8266 Wi-Fi module chip and Global System for Mobile Communication (GSM) has incorporated into a framework to employ these wastage bins.

Abstract The implementation and accuracy of a low-rate (~1 Hz) horizontal wind measurement system is described for a fixed-wing aircraft without modification to the airframe. The system is based on a global positioning system (GPS) compass that provides aircraft heading and a ground-referenced velocity, which, when subtracted from the standard true airspeed, provides estimates of the horizontal wind velocity. A series of tests was performed flying “L”-shaped patterns above the boundary layer, where the winds were assumed to be horizontally homogeneous over the area bounded by the flight (approximately 25 km2). Four headings were flown at each altitude at a constant airspeed. Scaling corrections for both heading and airspeed were found by minimizing the variance in the 1-s wind measurements; an upper limit to the error was then computed by calculating the variance of the corrected wind measurements on each of the four headings. A typical uncertainty found in this manner tends to be less than 0.2 m s−1. The measurement system described herein is inexpensive and relatively easy to implement on single-engine aircraft.
