The Positioner Setup feature in enigma 2 images can be useful for several things. For example, you may use the Positioner Setup to quickly re-calibrate a ku dish motor or c band actuator. The Positioner Setup may also be used in satellite dish alignment.

Autofocus is a feature in Positioner Setup that allows or aides in the calibration of satellite positions. The Autofocus feature works very well for c band actuators, but currently needs more work to be of much use for ku dish motors. In most enigma2 images, Autofocus is extremely slow to the point that it is almost unusable. Autofocus has been sped up considerably in TNAP images, and its accuracy seems to be improved.

There are two speeds for Autofocus. These speeds are automatic and are not user adjustable. The Symbol Rate size of the transponder dictates the speed. Transponders with a symbol rate of 5000 or less should move slower because the Autofocus feature is looking for transponder lock. Transponders with a low symbol rate may take longer to lock, or have an unsteady lock which can cause problems in the Autofocus feature.

The Autofocus feature will create logs that can be stored indefinitely by the user. The default location for postionersetup logs is /tmp of receiver files. Log files should automatically be stored on hdd or usb drives if a folder named positionersetup is created for log storage at one of these locations in receiver files.

Calibration of a satellite position using autofocus may take one to two minutes or Less, depending on how wide the transponder is. Calibration time will be slower on low symbol rate transponders.

Some of the features mentioned here are available in previous versions of TNAP. All of the Positioner Setup features mentioned here will be available in TNAP-5 images.
