Hi everybody. I have apm2.8 with BeStar BN-880 (U-blox m8n) gps.
In u-center everything is ok ; i am getting 7-8 sats. in indoors with hdop1.1.
When i connect to apm via usb everything is also ok.
But when i connect the battery to power module which powers the apm, escs. and everything else; gps is getting crazy. For one second it captures 5-7 sats than suddenly nothing and again 5-7 sats for a sec. than again 0.
Gps is at least 15 cm. away from escs.
Any ideas???
Thanks.
Hi Ruby81,
this is my first post here, but I would like to help you.
I have the M8N GPS (but not BeStar BN-880), have you checked that all parameters are set correctly?
You should dowload the U-center from ublox website and connect the GPS (throught USB) and check if all parameters are ok.
I use the M8N on Pixhawk, and I have to set the parameters before use, unless it doesnāt recognize the module.
I would like to say ācheck if the cable is okā but I donāt know if you buy a cable or do it yourself.
Hope I can help further, sorry for my english!
Hi. Thanks for replay. I had problem with cable also the shield was not soldered good. A few days ago it almost flyed away and crashed in to the tree. For more than 2 weeks I didnāt touch anything. No one is helping here so I think I am gonna quit.
If you have another cable try it! I had problem with GPS in the past for the stupid DF13!!
Are you using the original power module?
- With the voltmeter measure if the voltage out of the power module is the same that arrives at the GPS module (it should be equal or really close too)
- Check if power cable runs close to GPS cable
P.S. Sorry for āstupid DF13ā but I really donāt really like that connectors! I would like to have 2 version of pixhawkā¦1 with DF13 for small UAV and 1 version with better connectors.
