Error Compensation for Cricket Indoor Location System

The Cricket indoor location system

Indoor environments present opportunities for a rich set of location-aware applications such as navigation tools for humans and robots, interactive virtual games, resource discovery, asset tracking, location-aware sensor networking etc. Typical indoor applications require better accuracy than what current outdoor location systems provide. Outdoor location technologies such as GPS have poor indo...

Lessons from Developing and Deploying the Cricket Indoor Location System

The Cricket indoor location project has been active for four years. We have developed three different versions of the system. The first version was an early proofof-concept (Cricket v0), which led to the first prototype (Cricket v1). Cricket v1 has seen extensive use by us and by a few other research groups in the community. During this time, we have learned a number of lessons from application...

Error Estimation for Indoor 802.11 Location Fingerprinting

802.11-based indoor positioning systems have been under research for quite some time now. However, despite the large attention this topic has gained, most of the research focused on the calculation of position estimates. In this paper, we go a step further and investigate how the position error that is inherent to 802.11-based positioning systems can be estimated. Knowing the position error is ...

A Novel Magnetic Indoor Positioning System for Indoor Location Services

In this contribution an accurate Magnetic Indoor Positioning System (MILPS) currently under development is introduced. MILPS utilizes artificial magnetic fields generated by coils for ranging between multiple coils and a magnetic sensor. The proposed DC magnetic signals have excellent characteristics for penetrating various obstacles in indoor environments and show neither special multipath eff...
