BE-880 GPS Receiver Module TTL IST8310 Compass 10th Chip 38400bps for Arduino FPV Aircraft CC3D Flight Control, Replace BN-880 GPS

Work fine, note you will need to add correct the SBAS PRNs for it to work more accurate in UK. It can go <1m accuracy in good condition. Support up to 3 concurrent systems. Give accurate route for my use. The description does not say about Glonass but I managed to enable it and it works fine too. Use U-center for the configuration. Things to consider: - The internal compass need to be well calibrated before use, (all compass does but this one has way more offset). It is useless if not combined with other sensors for tilt compensation. - The backup battery only last for around 30mins (I did leave it charged for 2 days) where it should last for at least weeks or months. This is bad so I gave it 4 stars.

As the headline says, the GPS worked great, but the compass had issues. At boot up of my Flight Controller the GPS always worked fine, even indoors, but the compass was kind of hit or miss. Sometime it would work and sometimes it wouldn't. It calibrated just fine, but during normal operating conditions sometimes it would be stuck at one particular compass angle and other times it would respond normally. Needless to say, the compass caused numerous preflight arming errors.

Be careful to get the one that supports the bad rate you need for communication. I ended up needing to buy two before I got it right, but that isn’t the fault of the module and they work great (I could also likely reprogram the rate if I dug in).

Gets fix super fast. Better than matek m10q by a lot.

I used this in a inav fixed wing build. It locks fairly quick and is tough enough to withstand a hard landing or 2.
