Kalman+ is Android Location Manager that delivers location predictions based on a Kalman filter. Use Kalman+ in Android to receive filtered Location estimates.

It takes advantage of a Kalman filter algorithm to predict fixes (ordinary Android Location objects). Measurement updates are gathered from either the GPS or Network provider (or the combination of both),  taking into account the difference of those updates to calculate their contribution to the predicted fix.

Gain accuracy by setting a filter update interval slower than the real provider update interval. Each fix measurement improves the accuracy obtained for a filter estimate.

All results you can see in two files with name "config.txt" and "follow.txt". You can find files in your mobile under the folder DCIM and sub folder "Kalman".

When you start Kalman+ both txt files will be deleted.

- Request location updates with the highest possible frequency
- For the network provider, which gives locations with less accuracy (less reliable), request updates every 5 seconds.
- For the filter-time argument we use a "real" value: the predictions are triggered by a timer.

Geodetic 6 Parameters Transformation

Don't forget to subscribe my youtube channel. Ne zaboravite da se prijavite kao pratilac na moj youtube kanal

The Estimation of Geodetic Datum Transformation Parameters. App Geodetic6parameters is developed for the computation of the 6 parameters of the 3D similarity transformation between geodetic reference frames, calculates from identical points in different geodetic Reference Systems (3 translations, 3  rotations).

I am adding SD card (storage) permission in my code, but whatever i recommended to check SD card (storage) permission. Go to settings, app, find app geodetic7parameters and allow SD card (storage) permission.

Input coordinates must be only in Cartesian format : name Y X Z (system A and system B).

The Affine 4 parameters transformation



Don't forget to subscribe my youtube channel. Ne zaboravite da se prijavite kao pratilac na moj youtube kanal

The parameters are: two East/North translations, rotations, the scale factor and the rotation angle.

The Affine 4 parameters transformation is one of the possible methods to transform coordinates in plane. Mathematically, to transform the coordinates from one reference system to another, at least the coordinates of 2 points in both systems are needed

Even though 3 known points in both systems are sufficient to solve this transformation, it is obviously advised to use more points in order to have a more accurate calculation

I am adding SD card (storage) permission in my code, but whatever i recommended to check SD card (storage) permission. Go to settings, app, find app geodetic9parameters and allow SD card (storage) permission.
