In November, two companies unveiled indoor location positioning systems. CSR, Plc. demonstrated its indoor location and navigation system at the Locations & Beyond Summit in San Francisco in November. CSR’s SiRFusion location platform and SiRFstarV architecture are scheduled to become available...More>>

Navizon Inc., a provider of geolocation technology, has unveiled Navizon Indoor Triangulation System (I.T.S.), an indoor positioning system. Navizon is the creator of a previous application called Navizon-One, a global positioning system combining GPS, Wi-Fi, and cellular signals.More>>

Cell-phone users are often more concerned about the speed of positioning than the accuracy, making time-to-first-fix the most important factor in a GNSS mass-market receiver’s perceived performance. However, TTFF is generally difficult to characterize and optimize because of the need to encompass...More>>

"A large number of companies and engineers have thrown billions of dollars at trying to improve GPS in urban and indoor applications,” states Locata Corporation co-founder Nunzio Gambale. “From a technological perspective, Locata has created something completely new: the capability to...More>>

Alcatel-Lucent has partnered with Polaris Wireless and Thales Alenia Space to offer a mobile device geographic positioning service. This type of service needs to be highly accurate to provide the best results for phone operators carrying out applications such as E911 as well mobile marketing....More>>

An indoor messaging system (IMES) has been developed to meet the challenges of indoor and deep indoor positioning, as a system that can be implemented in any device that has a GPS/GNSS receiver without hardware modification. IMES can provide reliable 3D position data with a single transmitter...More>>

Navteq has announced the launch of Navteq Destination Maps. Destination Maps feature a unique set of interior map attributes (for instance, escalators) with detailed place data to enable users to more efficiently navigate and explore interior spaces. With Navteq Destination Maps, location-based...More>>

This paper introduces a Smartphone positioning solution for indoors based on the wireless signal opportunities and the built-in navigation sensors in smart phones. The proposed solution is based on a hidden Markov model solved with a Viterbi algorithm. The solution takes the advantages of the...More>>

This article presents a simple solution to one of the main challenges of indoor pedestrian navigation.  Many researchers have shown the benefits of using low cost shoe mounted IMUs, but the major drawback of these systems is the rapid and dramatic growth in heading drift error.  The method...More>>

Low cost MEMS gyros and accelerometers are often considered as a potential solution for indoor navigation, but the reality is that such sensors are only sufficient to provide useful positioning for very short periods of time. This is due to sensor errors such as biases and scale factor errors that...More>>
