With the development of related applications, indoor positioning techniques have been more and more widely developed. Based on Wi-Fi, Bluetooth low energy (BLE) and geomagnetism, indoor positioning techniques often rely on the physical location of fingerprint information. The focus and difficulty of establishing the fingerprint database are in obtaining a relatively accurate physical location w...

Superconducting Quantum Interference Devices (SQUIDs) are known to be the most sensitive magnetometers, used in a wide range of applications like biomagnetism, geomagnetism, Non Destructive Evaluation (NDE), metrology or fundamental science. For all these applications, the SQUID sensor is used in analog mode and associated with a carefully designed room-temperature control and/or feedback elect...

Geomagnetic field is highly applicable to indoor localization due to its pervasive spatial presence, high signal stability and infrastructureless support. Previous work in the area often fuses it with pedometer (step counter) via particles. These approaches are computationally intensive and require strong assumptions on user behavior. To overcome the weaknesses, we propose Magil, a pedometer-fr...

Abstract The application of magnetic field detector in the actual road section mainly depends on layout these detectors traffic environment. For example, geomagnetism and coils are easily disturbed by vehicles near road, resulting missed or false detection; Video detection equipment weather, visibility other environmental conditions, there will be a large degree detection. Compared with disadva...

Abstract. Measurement of the geomagnetic field in Indonesia is undertaken by Meteorological, Climatological, and Geophysical Agency (BMKG). Routine activities at each observatory include determination declination, inclination, total using absolute variation measurements. The oldest Tangerang (TNG), started 1957, followed Tuntungan (TUN) 1980, Tondano (TND) 1990, Pelabuhan Ratu (PLR) Kupang (KPG...

Indoor localization has become a popular topic with the development of location-based services (LBS) and indoor navigation systems. Beside these circumstances positioning been focus attention for researchers as most important component applications. Many signals are used distinguishable features positioning. RF-based Wi-Fi BLE systems ones have preferred because their high feature. The use geom...

Abstract. Palaeomagnetism is a relatively unknown part of Earth sciences that not well integrated into the school curriculum in UK. Throughout recent years, there has been decline number science students In 2018 and 2019, we developed outreach activities resources to introduce scientifically engaged general public palaeomagnetism raise awareness how geomagnetism affects society today, thus putt...
