Hi everyone

I have had my p3s for a few weks and absolutley loving it.  Getting more advetnurous each flight.  Ihave just uploaded my flight logs to healthy drones and when reviewing each of my flight the gps does not show better then Good.  Every track is poor or good.  I am flying in a rural area with no interference, signal scores have been all good.  Just wondering if it is a thing for Australia that we have less satalite coverage.
cheers
Adrian

I average about 8, what are you getting and where are you flying?

Looking on healthy drones it says POOR 6 to 10 and then I get good which says 10 to 15.  I am in Inverleigh, Victoria.  I guess I'm not too bad if you get 8.

OK, I have a friend in Ombersley, not too far from you. You should see all available satellites there as there are no deep valleys or high mountains. I average 8, but often get a few more. Don't forget, we hardly get any of the Russian GLONASS sats, are they are mostly in the northern hemisphere, wheras the Americans get them.

8??? Where are you flying?? Between a valley?? in a basement??
I'm in Sydney and I get 14-16 on average.

There could be a chance that your puck could be cracked and losing once of the Glonass/GPS frequency.
It doesn't take much, just a microfracture in the ceramic puck to make it drop a handful of sats.

He has a Standard so it doesn't pick up the Glonass sats at all.
Eight is fine and the number you see will vary as the sats come and go.
Being in Australia won't afffect how many of the US GPS sats you see.

I didn't know the Standard did not receive GLONASS, something to add to the memory store. Yet more reason to steer away from one.

To quanthonytrang, yes, I am in a bit of a valley in the Gippsland hills. It limits my view of the sky to the west and north to some degree.

im near la ca. out of the city in on av. 12 in city 8,9. the most
15

no glonass on standard

Ooops my bad.
I didn't see the little 's' in the topic.

I still think 8 is terrible.
My obsolete P2 Vision Plus with a foil mod picks up 10-14 sats.

Eight is not terrible for a P3S, it's just on the low side. I have one and average between 8 and 10, with 11 being the best I've ever gotten. When I use the UAV Forecast app it usually only shows 9 or 10 sat in view on a good day with a GPS Elev. Mask set at 5°. So if there's only 9 or 10 in view can't be higher than that can it.

Don't think Healthy Drones adjust it's GPS rating just because we have a Standard. You will NEVER get it to show "Excellent" (green) on their site with a Standard. It would need to be 15+ for that. Poor or Good is about as good as it gets.

A GPS unit needs 4 sats to get a proper fix (as long as the geometry is good).
DJI set the Phantom to only use P-GPS mode with 6 to allow a safety margin so 8 might be toward the low end but still quite acceptable.

I see what you are saying. 4 sats is a proper fix. Its good when that device is your car or in your hand like a mobile phone.
But when that device is hardly visible, 6-8 is a high chance of a lost bird to me.
6 is red/green flashes ATTI mode and 7 is only enough to find its way home.
If you live in valley and the sats happen to move and its not in your favour...

Thanks wmcvey, that is what I was thinking, happy to have it confirmed.

Damn, I just ripped off my P3S' CF skin thinking somehow it's interfering with the GPS reception. Sigh, there goes $25.
