A

GPS or IMU. This key word explains the content of the file.

GPS :This file contains the GPS-coordinates.

IMU :This file contains the GPS-coordinates and IMU angles.

 

A

Usually it is expected that for every event the time is indicated, the GPS-data are reduced to the projection centre and the IMU rotation angles are indicated in grades with the data and rotation sequence φ, ω, κ. These settings can be changed by the following options:

+e :The GPS-coordinates are related to the antenna position.

+o :Data and rotation sequence of the angles is ω, φ, κ.

+9 :The IMU angles are indicated in degree.

-t :Time indications are not included in the file.

4F

Factor(s) for standard deviations of the GPS/IMU data.
The first two values are for X/Y and Z of the GPS coordinates, the third value for φ and ω, the fourth value for κ.
With these values all standard deviations in the data file will be multiplied. For missing standard deviations in the file these values will be used instead.

An unlimited number of files can be indicated for GPS or IMU data. When using the option +e, a vector e´ is automatically assigned to the corresponding camera, which shows from the projection centre to the antenna.

If multiple FILE statements are used in one data set, all of them have to be of the same type: GPS or IMU. It is forbidden to use different key words. But different vectors e´ can be used from the projection centre to the antenna, per camera one vector.

If the option +o is indicated, BINGO transforms the angles ω, φ, κ immediately after reading into rotation sequence φ, ω, κ. This conversion will be done by creating the rotational matrices for the ω-φ-κ rotation angles and estimation of the φ-ω-κ rotational angles according to the formulas in chapters 2.1.1.1 or 2.1.1.2. Changing simply the rotational angles would lead to wrong results. The transferred values can be indicated in the list file when the related output option is set.

Attention:
The GPS event numbers have to be unambiguous about all GPS-data files. No number has to be there twice.
