[Gpredict-discussion] Tracking Issues

[Luca B. <luc...@st...>]

Hello,

I'm using Hamlib 3.0 with Gpredict in order to control a Alfaspid Rotator with a Rot2Prog controller and I'm experiencing some problems.

I can give orders via the controller (using its buttons), via cmd with rotctl and within the Rotator Control of Gpredict (calling rotctld in cmd) and as long as these commands are given manually there are no issues. However when I track a satellite something strange happens. The rotator will be out of position while the controller indicator give a wrong reading. For example let's suppose that a tracking should finish in 0° Azimuth and 0° Elevation: the controller and all the readings give (0,0) while the antenna is still pointing up and not at North.  Every time I have to recalibrate the direction, and I can't say with accuracy when it sart to lose it.


I am assuming that is a software error since, as i said before, the other methods do not give errors.


I am using  Gpredict V 1.3-3, with the Hamlib 3.0 in Windows 8.1 (I know, but the laptop is not mine).

To activate the Hamlib driver I use:


rotctld -m 901 -r COM7 -T 127.0.0.1 -t 4533 -vvvvv


For the tracking: 3000 ms cycle and 1° Tolerance


>From the verbose in the cmd all seems fine, but I'm no expert.

Thanks in advance for any help.
