The Need for a dedicated Foot Mounted Navigation Device for

Indoor Positioning

Introduction:

In this paper we highlight the requirements and provide a comparison of the various technologies

available in the market today. In summary we conclude that, a foot mounted inertial navigation sensor is

the ideal solution for indoor position market as it is not dependent on prior presence of infrastructure.

Requirements:GPS does not work indoors and companies are racing to map and capture the Indoor positioning market.Some of the popular applications for indoor positioning can be classified into

1.

Navigation and Guidancepedestrian navigation

2.

Tracking and Monitoringfriend/co-worker finding

3.

Situational AwarenessFirst Responders

The key parameters to be considered during the selection of indoor positioning system application are -

1.

Accurate 3D co-ordinates (needs to be in the order of tens of meters or lower; for example, in

which floor is the first responder? Co-ordinates must be reliable in the presence of interferencelike multipath/fading)

2.

No/less dependency on infrastructure for computing location (WiFi/BT routers require

permission from site owners to use the equipment; Battery and Co-ordinates of the

infrastructure equipment must have less impact the co-ordinate readings )

3.

Time to first fix (can the system report the location in < 1s)

4.

Update rate (can the system track at a rate of 100Hz+)

5.

Open System (no licensing cost)

6.

Ease of integration and ability to fuse multiple sensor data

7.

Low total System Cost (infrastructure, device, monthly service cost)

8.

Power Consumption9.

Privacy Concerns

10.

Availability of indoor 3D maps
