Name

Angle of arrival (alpha)

Description of the information measured

Angle of arrival of RF-signal measured by the antenna array and calculated with methods like MUSIC

Units

degree

Example values

35

Frequency of generated data in operation

angular is generated nearly every second.

 

Name

Angle of arrival (phi)

Description of the information measured

Angle of arrival of RF-signal measured by the antenna array and calculated with methods like MUSIC

Units

degree

Example values

-10

Frequency of generated data in operation

angular is generated nearly every second.

 

Name

Distance Measurement

Description of the information measured

Distance between Transponder and location device measured of RF-signal

Units

Distance in m

Example values

1.23

Frequency of generated data in operation

Distance is generated nearly every second.

 

All data are recorded in a more detailed protocol file. In this file we record the different parts of the signal and their signal strength and also information from sensors like movement and barometric sensors. At the moment this protocol file is for internal use only, but there could information extracted afterwards.

After, for instance, 30 minutes operation you generate the following data sets (this is the information you will finally provide to evAAL together with this questionnaire in a format that must be agreed before the competition). Please provide information about the files with data (examples are, text file, or video) and format (.csv, .txt, .xls…).

  1. An array that include: [time, device IDs, distance, alphaAngularValue, PhiAngularValue, X-Position, Y-Position, arcRadius], nearly  every second.
