#8459: [PATCH] Calculate correct Azimuth positioning for Diseqc Rotor
---------------------------------------------------+------------------------
Reporter: Pieter Hoekstra <pieter@…> | Owner: janne
Type: defect | Status: new
Priority: minor | Milestone: unknown
Component: MythTV - DVB | Version: 0.23rc2
Severity: medium | Mlocked: 0

I'm not 100% sure this is a mythtv bug or my misunderstanding.
When positioning a rotor using GotoXX-diseqc (Diseqc1.3) commands, Myth
calculates the Azimuth-angle for the current latitude/longitude.
This Azimuth is visible when running "mythbackend -v important,channel"
When I compare the Azimuth with other software, like kaffeine, SMWLink
(www.smw.se/FreeSoftware.htm), xdipo
(http://panteltje.com/panteltje/satellite/) or sites like
http://www.dishpointer.com
http://www.satsig.net/ssazelm.htm myth seems a few degrees wrong...
Example: For my location the Astra19.2E satellite should point to 15.3E,
but myth calculates 13.5E
I have attached a patch that calculates the same value as the calculators
above.
The current code also calculates the elevation, I removed those lines in
the patch.
