Gps comparison

Jimmy5498 · Mar 12, 2020

Tonight I had both aircraft, my Q500 and H Pro powered and connected to there respective controllers. This was inside my garage.

The Q500 locked in 10 seconds to 12 sats.

The H had 10 sats but constantly showed ‘Acquiring’

Are the gps modules the same?

They were located approx 3 feet from each other

any ideas would be a help guys

Might be better posting in a more appropriate section. Nothing really to do with H3.

The garage is not an ideal place for a test of the GPS module

They are not the same, different part numbers. There are many variables that would make one acquire sats faster than the other.

How often have you been using the H Pro? If it only every couple of weeks or less you may have to let the H sit powered up for an hour or more to replenish the battery in the GPS module.

Agree the garage is not the best place but it does show the difference in the GPS acquisition and lock of both aircraft.

Is the q500 the same in respect of the internal gps battery do you know ?

It also has an internal battery, but not sure if they are the same one. See attachment 38 in the pdf linked here Way To Fix Drones project

What it shows is you have two different GPS units, neither having a certification standard, installed in different places of two different aircraft being tested in a poor testing environment. Essentially you have no usable data to form a conclusion.
