Anybody know anything about this one? It's $35 from Roboshop:
2.5dbI high gain and selectivity ceramic antenna
MMIC BGA715L7 from Infineon power amplify IC
SAWF (Surface acoustic wave filter) form Murata
HMC5983 from Honeywell geomagnetic
The Radiolink SE100 GPS Module for PixHawk exceed the limitation of IC sensitivity index from circuit schematic design to PCB placement.1 meters positional accuracy, positioning in 23 seconds and valley station keeping ability.

Markus, is this the one you use?

Hey Markus.
Could you please tell me which droteck GPS exactly you mean?
Thankyou!
I have this gps is not good the droteck is 2x better , droteck 15sat hdop 0,78 radiolink 7sat hdop 2,05
This would seem to emphasize the importance of good GPS antennas.
see RC Tech.se description....
Ceramic? Weight/dimensions? Those specs are not even on the radiolink website.
Is that pure Kryptonite in the center of it?
I wonder what the actual performance is like? As we know, the specific implementation actually does matter. Just because the same chips are employed, does not mean the performance will be the same as properly engineered alternatives.
