APM 2.8 board - GPS: NO fix

I added a Ublox NEO 7M GPS with compass to the APM 2.8 board. I used Mission Planner 1.3.72 version. Compass is correct working but showing GPS: No fix. I will benefit from your help.
Thanks in advance.

Are the wires correctly connected?

Is the Neo7 supported by the 2015 firmware?

Yes. I installed the wires correctly. Please give me some solution.

Take it outside and wait. GPS: No fix means it’s recognized but no sats.

But both that Flight Controller and GPS module are as old as dirt so do yourself a favor and replace them.


Thank you.
I shall try it.
My APM 2.8 work well. I bought clone of APM 2.8 for 1 year ago. Then I was flying drone without GPS. I have installed GPS few time ago and it shows GPS: No fix.

it can take up to 20 minutes to get a fix if its not been used before.


I put it more than 20 minutes of on desktop computer.

You have to go outside.

You should use a supported autopilot.


Thank you for reply.
Which light ardupilot is better to use the older version?
Please reply

Thank you.
According to this link the latest version for APM is 3.2.1.
I shall see.

Anything with a H7 MCU and 2MB flash storage. Matek H743-x, Holybro Kakute H7 etc. AocodaRC H743Dual looks very interesting while being one of the cheapest of the pack.

I will let you know if my problem is solved.

It’s fine replace them all you need is about £500 and that’s just the start. You then have to find some where you are allowed fly it. Assuming you are talking about a quad. Do yourself a favour, buy a ready made one on line, there are plenty of cheap drones about and its amazing what they are capable of.

For an FC and GPS? 120£ for midrange stuff, 80£ if you’re counting every penny.

I don’t know about RTF quads, how much are the ones running Ardupilot?

RTF drones have their raison d’etre, both commercially and in hobby spaces, but it’s a bit like suggesting people in a DIY performance race car forum to just buy a Golf GTI, because they’re pretty fast too.

I would like to know where you can get a FC for £120. The cheapest I have seen is £300 and that doesn’t include postage.

What? I suppose you are not aware of many supported Flight Controllers for far less than that. Matek, Holybro are a couple quality brands with inexpensive boards and there is the 2nd tier from others even cheaper but would still fly circles around an old APM.


I was talking about the updated pixhawk, more than just a flight controller, something you can attach peripherals, like sensors, gimbals, servos, telemetry data etc. The latest version is the pixhawk cube which costs, over £300.

Yea, like the Flight Controller @Oli1 linked to that cost $78. Where do get the idea you need something called a “Pixhawk” to do that?

What is it missing?
