# Description

Sensor Fusion is a process by which data from several different sensors are "fused" to compute something more than could be determined by any one sensor alone. An example is computing the orientation of a device in three dimensional space. That data might then be used to alter the perspective presented by a 3-D GUI or game.

This educational application by Freescale Semiconductor teaches you about sensor fusion and lets you experiment with various fusion options. It does not REQUIRE that your Android device use Freescale sensors. It is compatible with the Freescale Sensor Fusion Library for Kinetis MCUs. Compatible hardware and embedded software are available at http://www.freescale.com/sensorfusion.

The application also supports the Avnet Wi-Go module paired with a Freescale Freedom board (see www.em.avnet.com/wi-go for details). When used without a development board, this app just lets you experiment with what you already have on your Android device.

This tool is the subject of a Freescale blog posting at: https://community.freescale.com/community/the-embedded-beat/blog/2013/04/08/free-android-app-teaches-sensor-fusion-basics . The fusion library is discussed at https://community.freescale.com/community/the-embedded-beat/blog/2014/02/24/xtrinsic-sensor-fusion-library-for-kinetis. As of October 2014, the fusion library is being released in source form, at no cost.

Please report issues directly to sfusion@freescale.com.

Freescale Semiconductor (http://www.freescale.com) is a global leader in embedded processing solutions including MPUs, MCUs, sensors, analog integrated circuits and connectivity.

Fantastic Technology Demonstration This is the best demonstration of the motion sensor technologies in Android based products available on Google Play. Take an opportunity to try out the different source data modes in addition to the various views. The augmented reality view is quite smooth and impressive. Also, if you are trying to use motion sensor data it is quite easy to log the sensor data using this app. Very nice all around! Can't wait for additional features!

## Sensor fusion app

This sensor fusion app is intended as an illustration of what

sensor capabilities your smartphone or tablet have.

You can watch graphs of the main sensors in real time, except for

video, microphones and radio signals. You can log data to file

or stream data to a computer. The app is bundled with a a Matlab

interface which allows for on-line processing and filtering for

prototyping and demo purposes.

The first versions of this app was developed in collaboration

with HiQ (hiq.se), funded by a SAAB award in the name of former

CEO Åke Svensson.

The second version of this app, featuring a considerable rewrite

of the code base as well as extended functionality and Matlab

support, was developed by Gustaf Hendeby as part of introducing

the app as part of a lab in the Sensor Fusion course at

University of Linköping the spring of 2013.

Pleasant sensor exploration, wishes

## ISS Detector Satellite Tracker

RunaR

1

Have you seen the International Space Station? It is visible with the naked eye!

If you like space or astronomy, you will like this ISS locator app.

ISS Detector will tell you when and where to look for the International Space Station or Iridium flares. You get an alarm a few minutes before a pass. You will never miss a pass of the International Space Station and you will never miss the bright flashes of the iridium communication satellites. ISS Detector will also check if the weather conditions are right. A clear sky is perfect for spotting.

Extensions will enhance the functionality of ISS Detector. With an in-app purchase you can add comets and planets, amateur radio satellites and famous objects, like the Hubble space telescope or the Chinese space station Tiangong.

• Overview of the coming passes

• Weather conditions for perfect sightings

• Radar screen with path indication

• Current location on a map

• Detection of Iridium flares

• Notifications and Alarms

• Share sightings with whatsapp, twitter, gmail, email etc.

• Automatic location and timezone detection

• Widget

• Dedicated tablet layout

Available Extensions (in-app purchase):

Radio Amateur Satellites

Track dozens of ham and weather satellites

Famous Objects

Track Hubble, X-37B, Fitsat, Tiangong and more

Comets and Planets

Track comets as they come closer to earth. Perfect for C/2011 L4 Panstarrs in March 2013 or C/2012 S1 ISON in November 2013.

Enable ISS Detector to display the positions of the planets on the radar view.

ISS Detector combines data from Nasa, Heavens-above.com, minorplanetcenter.net and weather from yr.no.
