“…Several attempts on indoor positioning have been made. The most successful and promising technologies seems to be the use of WiFi (Moen and Jelle 2007, Schrooyen et al 2006, Fry and Lenert 2005, Muñoz et al 2003, ultrasound (Mautz 2009) and the new Galileo system (Yang et al 2007). Based on this we believe that indoor positioning will be available in the near future.…”

ABSTRACT:Efforts within cartography on indoor maps have previously not received a lot of attention. Work that has been carried out on indoor maps often focus on map design very similar to an architectural style (Klippel et al. 2006, Ciavarella andPaternò 2004). In some cases the design has been of a more novel character where approaches with augmented and virtual realities have been carried out (Radoczky 2007, Müller et al. 2006). Common to these approaches is the depiction of one floor per map. As well, the primary user task is often solely personal navigation. In this article we present an innovative approach to indoor maps. The design is directly inspired by underground tube maps first developed by Harry Beck (Garland 1994) and today a common design for public transport maps. The main advantages of the map design are its simplicity and the possibility of including all floors in one map view. This allows the map user to easier comprehend the structure of the building without using several maps, as commonly needed with today's indoor map designs. We present two different map styles each intended to satisfy different user groups and tasks depending on the user's familiarity with the environment. In addition we motivate for new application areas suitable for indoor maps, especially large hospitals. We hypothesize that the design proposed in this article leans very well to displaying real-time dynamic geospatial information, such as patients, staff, equipment and room availability within hospitals. Due to the early phase of the work presented here we outline the needed further work and possibilities of technological platforms as well as evaluations necessary in order for the design to gain acceptance and success.

“…Apart from solutions designed for many places, applications for navigation in selected buildings are also developed. An example of such a solution is the 'Copernicus Science Center Guide 4 ' issued by Samsung Electronics in April 2012. The application aggregates general information for visitors and navigates them around the site.…”

The development of indoor navigation systems should utilize advanced teleinformation, geoinformation and cartographical knowledge. The authors analyzed available specifications of prototypes of indoor navigation systems and drew conclusions about how to enhance the use of cartographical methods in the whole process of designing a new system. The analysis proves that cartographical methodology is still very limited in the process of designing indoor navigation systems. Researchers focus mainly on improving the positioning accuracy, and they often neglect the issue of developing spatial databases and the rules of their effective visualization. The process of designing indoor navigation systems, just like in the case of outdoor navigation systems, consists of a number of tasks that can be supported by the theory and practice of cartography. This article presents the issues of determination of spatial database model appropriate for an indoor system, improvement of accuracy of positioning algorithms utilizing spatial data and methodology of generating graphical and voice directions for indoor navigation. In the authors' opinion, the discussed cartographical methods and techniques may considerably enhance indoor navigation systems and accelerate their development. The fundamental knowledge of cartographical methods should be within the interest of designers of these systems. At present the first attempts in this field may be observed, although they are still not mature and complex. Keywords:mobile cartography, building modeling, indoor navigation, GIS, LBS. INTRODUCTIONMobile applications, including Location-Based Services (LBS) and navigation systems for cars, bicycles, pedestrians as well as air and marine navigation systems have recently been widely popularized. These services utilize Global Navigation Satellite Systems (GNSS) to track the position of a user. As the GNSS signal is too weak indoors in order to provide navigation inside buildings, there are attempts to use other positioning technologies based on radio infrastructure (WiFi, RFID 1 tags, Bluetooth, UWB 2 ), ultrasounds, 1 RFID -Radio Frequency Identification. 2 UWB -Ultra WideBand, technology based on sending ultrashort pulses. vision systems, dead reckoning and other experimental approaches. In the near future it will be possible to locate a user inside shopping malls, in underground parking areas, hotels, hospitals, office buildings, etc. It will also be possible to navigate a user to a shelf with specific goods and provide personalized advertisements or send promotional coupons (mobile marketing). In case of emergency, the user will be updated with evacuation routes from their current location.

The development of indoor navigation systems utilizes advanced teleinformation, geoinformation and cartographical knowledge.

“…For any sufficiently small dt, a rotation vector can be derived directly from 3-axis gyroscope reading: (2) where: rv -rotation vector, gx, gy, gz -gyroscope readings (axes X, Y and Z) scaled to rad/s. Rotation vector can be converted to quaternion Q (or angle-vector representation) with the following:…”

Abstract.A method of attitude estimation with a low-cost, strap-on MEMS sensor was proposed in the article. The method relies on dynamic gyroscope bias change estimation and updates during detected stops of the robot. The algorithm has been tested in laboratory with iRobot Roomba robot and should be improved to be useful in an industrial environment. The measurement of attitude of a mobile platform is necessary for correct navigation, especially in autonomous vehicles, which use dead reckoning between position updates from external sources. Since the system is intended to operate indoors, in industrial halls and shops, it cannot avail of GPS and Earth magnetic field sensors because of anomalies, which are common inside the steel constructions. Therefore, the accuracy of the gyroscope-based attitude estimation is significant. The proposed method aims to address the common problem of gyroscope bias drift, by dynamic update of sensor bias and simultaneous use of all gyroscope axes, to improve the quality of the measurements. A popular 3-axial gyroscope and 3-axial accelerometer sensors were used during the test runs. Obtained results suggest that it is possible to improve short-term accuracy of inertial dead reckoning, to get a system that could be of practical use in industrial AGV systems or intelligent vehicles.
